Structure and function of the feeding apparatus in the common musk turtle Sternotherus odoratus (Chelonia, Kinosternidae)
Authors: Natchev Nikolay , Heiss Egon , Singer Katharina , Kummer Stefan , Salaberger Dietmar , Weisgram Josef
Published: April 2019

The present study examined the kinematic patterns of initial food uptake, food transport, pharyngeal packing and swallowing in the common musk turtle Sternotherus odoratus. These data are supplemented by morphological descriptions of the skull and the hyolingual complex. Although the hyoid is mainly cartilaginous, S. odoratus still use exclusively hydrodynamic mechanisms in prey capture and prey transport. The tongue is relatively small, with weakly developed intrinsic musculature. We propose that the elasticity of the hypoglossum and the hyoid body impacts the capability of S. odoratus to suction feed, but allows these turtles to effectively re-position the food items within the oropharyngeal cavity during transport, manipulation and pharyngeal packing. We standardised conditions in all feeding events by using food items of the same consistence and size, and by always offering the food at the same position at the bottom of the aquarium. Nonetheless, the measured kinematic values varied considerably. The duration of prey capture and prey transport cycles were relatively long in S. odoratus compared to other freshwater turtles studied so far. The initiation of hyoid retraction relative to the onset of jaw opening can be modulated not only in prey capture but also in prey transport cycles. In the common musk turtle, the jaw and hyoid movements apparently have a low level of integration.
Molecular phylogeny and shell microstructure of Fungiacava eilatensis Goreau et al. 1968, boring into mushroom corals (Scleractinia: Fungiidae), in relation to other mussels (Bivalvia: Mytilidae)
Authors: Owada Masato , Hoeksema Bert W.
Published: April 2019

Research on the evolution of the symbiosis between the boring mussel Fungiacava eilatensis (Bivalvia: Mytilidae) and its mushroom coral hosts (Scleractinia: Fungiidae), which requires phylogenetic reconstructions of both the Mytilidae and the Fungiidae, contributes to the understanding of the complexity of coral reef ecosystems. Previously, Fungiacava was regarded as a genus that had descended from Leiosolenus or as belonging to the subfamily Crenellinae, but no phylogenetic support has been obtained for this hypothesis. In the present study, the 18s rRNA sequences of ten mytilid species and the shell microstructures of 12 mytilids were investigated. The phylogenetic position of F. eilatensis is discussed in relation to its associations with its host species. The results of the molecular phylogenetic analysis indicate that F. eilatensis forms a sister group with Leiosolenus simplex, a livecoral- boring species within the Leiosolenus clade. Scanning electron microscope observations indicate that the shell of F. eilatensis is constructed of 3 layers: the outer shell layer with a homogeneous structure, the middle shell layer as a sheet nacreous structure, and the inner shell layer with an irregular simple prism structure. This shell microstructure of F. eilatensis is similar to that of Leiosolenus malaccanus and L. simplex. These findings show that F. eilatensis has descended from a coral-boring Leiosolenus species and that it would be adequate for Fungiacava to be treated as Leiosolenus. However, because of its extraordinary shell shape it has been kept as a separate genus.
The ecology of shell shape difference in chirally dimorphic snails
Authors: Schilthuizen Menno , Haase Martin , Koops Kees , Looijestijn Sylvia M. , Hendrikse Sigrid
Published: April 2019

The Southeast-Asian tree snail subgenus Amphidromus s. str. (Gastropoda Pulmonata: Camaenidae) is unusual among all gastropods for its genetic antisymmetry: populations consist of stable mixtures of individuals with clockwise (dextral) and counterclockwise (sinistral) coiling directions. Although previous studies in A. inversus suggest that this genetic dimorphism is maintained by sexual selection, it cannot be ruled out that environmental factors also play a role. Adult shell shapes in A. inversus are known to show subtle differences between both coiling morphs, and it is known that in snails in general, shell shape is under environmental selection, thus creating the possibility that micro-niche use of both coiling morphs differs. In this paper, we first confirm that hatchlings also differ in shell shape. We then proceed with field studies to compare dextral and sinistral juveniles and adults for (i) direction and rate of dispersal within the vegetation and (ii) micro-niche occupation. However, we failed to detect any difference in both ecological traits. In addition to earlier data that show that there is no clustering of morphs in the field and that both morphs suffer identical predation pressure, these new data do not provide any evidence for a role for environmental factors in maintaining the coil dimorphism in this species.
Correct type designation of the Linnaean name Satureja graeca, basionym of Micromeria graeca (Lamiaceae)
Authors: FERRER-GALLEGO PEDRO PABLO , SENAR ROMÀ , LAGUNA EMILIO
Published: April 2019

Some aspects concerning the typification of the Linnaean name Satureja graeca, basionym of Micromeria graeca (Lamiaceae) are discussed. This name had previously been “typified” by Siddiqi in 1985 from a specimen kept at LINN, and also later by Morales in 1991 from another specimen preserved in the same Linnaean herbarium. However, it is not sure that these specimens are part of Linnaeus’s original material so neither cannot be considered a lectotype. An illustration published by Morison in 1699 and cited by Linnaeus in the protologue of Satureja graeca is designated as the lectotype of the name.
A new species of lizard of the Liolaemus elongatus clade (Reptilia: Iguania: Liolaemini) from Curi Leuvu River Valley, northern Patagonia, Neuquén, Argentina
Authors: AVILA LUCIANO JAVIER , PEREZ CRISTIAN HERNAN FULVIO , MEDINA CINTIA DEBORA , SITES, JR. JACK WALTER , MORANDO MARIANA
Published: April 2019

A new species of the Andean-Patagonian Liolaemus elongatus clade is described. Liolaemus burmeisteri sp. nov. differs from other members of its clade in a character combination of light brown general coloration, plain dorsal pattern, dark lateral areas, a very bright orange-yellow coloration on femoral area and lower belly, and other morphological and genetic traits. It is distributed on a restricted area on sedimentary rocky outcrops found in an intermountain valley. Liolaemus burmeisteri sp. nov. is known only for its type locality in Curi Leuvu River Valley in northwestern Patagonia above 1037 m. A mitochondrial DNA gene tree analysis found this new species as the sister taxon of Liolaemus smaug.

The concerned specimen is briefly described and illustrated. A key to the species of Loxopsis Westwood, 1859 is presented
Redescription of Leptolalax gracilis (Günther, 1872) from Borneo and taxonomic status of two populations of Leptolalax (Anura: Megophryidae) from Peninsular Malaysia
Authors: DEHLING J. MAXIMILIAN
Published: April 2019

A number of populations of Leptolalax from Borneo and Peninsular Malaysia have been assigned to Leptolalax gracilis in thepast, rendering it a supposedly morphologically variable and widespread species. Whereas some of the Bornean populationshave since been described as distinct species, many lowland populations from Borneo and montane populations from Peninsu-lar Malaysia remain assigned to L. gracilis. Several distinct species appear to be hidden under this nominal taxon. In order toresolve the identity of L. gracilis and clarify the character states and their variation within the topotypic population, the speciesis redescribed based on examination of the holotype and recently collected topotypic material. Furthermore, the taxonomic sta-tus of two populations from Peninsular Malaysia (Gunung Benom, Gunung Tahan) that have been assigned to L. gracilis isreassessed. Reexamination of the corresponding vouchers revealed strong morphological differences between the two popula-tions and between each population and L. gracilis from Borneo. The population from Gunung Benom differs from all species ofthe genus and is apparently undescribed. The population from Gunung Tahan is represented only by two not fully metamor-phosed juveniles and cannot be assigned unambiguously to any of the described species of the genus. It is possibly another undescribed species but more specimens, especially adults, need to be collected.
Two new species of Roquettea Mello-Leitão, 1931 from northern Brazil (Opiliones: Laniatores: Cosmetidae)
Authors: KURY ADRIANO B. , FERREIRA CLÁUDIO P.
Published: April 2019

Two new species of the genus Roquettea Mello-Leitão, 1931 (Opiliones: Cosmetidae) are described from Pará State,northern Brazil. Roquettea carajas sp. nov. has two broad swellings on mesotergal area I of male and Roquettea peba sp.nov. has a wide and high eye mound with globoid eyeballs and the closest structure to a chelate pedipalpus in Laniatoresso far described. Both species have greatly thickened conic apophyses on mesotergal area III. A key is given to the (now)6 species of Roquettea. The described diversity of genus Roquettea increased from only one species to six in only a few years, mostly known from only a few specimens, suggesting a high degree of undersampling of those rare cosmetids.

For genus Arcynopteryx type species is fixed(under Article 70.3 of the Code) as Arcynopteryx dichroa (McLachlan, 1872), misidentified as Arcynopteryx compacta (McLachlan, 1872) in the original designation by Klapálek (1912).
Water mites delineating the Oriental and Palaearctic regions—the unique fauna of southern Iran, with description of one new genus, one new subgenus and 14 new species (Acari: Hydrachnidia)
Authors: PEŠIĆ VLADIMIR , SMIT HARRY , SABOORI ALIREZA
Published: April 2019

This paper deals with a collection of epigean and hypogean water mites from the Hormozgan and Sistan va Baluchestan prov-inces in southern Iran. One new genus, Haloaxonopsis, is described, characterized by the presence of so-called wheel-likeacetabula, a unique character so far known only in marine mites of the family Pontarachnidae. One new subgenus, Halolimne-sia, and fourteen new species are described: Hydrachna sistanica, Nilotonia hormozgana, Torrenticola asadiae, T. hormozgan-ensis, Monatractides martini, Neoatractides calidus, Limnesia diversipes, Atractides hormozganus, Javalbia persica,Axonopsis gloeeri, A. interstitialis, A. hyporheica, Haloaxonopsis salina and Albia hyporheica. The first descriptions of thefemale are given for Neumania cf. maharashtris Cook, 1967 and Arrenurus bharatensis Cook, 1967. The following species arereported for the first time in Iran: Hydrachna cf. vaillanti K. Viets 1951, H. globosa lacerata Lundblad, 1969, Diplodontus sil-vestrii (Daday, 1898), Hygrobates hamatus K. Viets, 1935, Atractides biscutatus Cook, 1967 and Arrenurus bharatensis Cook,1967. The zoogeographical and ecological characteristics of the water mite fauna of southern Iran are discussed. The fauna ofSE Iran is of Oriental character, and no typical Palaearctic species were found. Our study shows that this fauna is not transitional, suggesting a rather ‘sharp’ boundary between the Palaearctic and Oriental regions in southern Iran.

Three new species of land flatworms and comments on a complex of species in the genus Geoplana Stimpson (Platyhelminthes: Continenticola)
Authors: AMARAL SILVANA VARGAS DO , DE OLIVEIRA SIMONE MACHADO , LEAL-ZANCHET ANA MARIA
Published: April 2019

Three new species of Geoplana Stimpson, 1857 from south Brazil, Geoplana ficki sp. nov., G. carbayoi sp. nov., and G.baptistae sp. nov., with dark, nearly homogeneous dorsum, reddish or orange venter, and eyes spreading over the dorsum,are described. The three can be included in the Graff group of “large, broad and flat species”, designated the G. applanata-group by C. G. Froehlich (1967). The first described species presenting this pattern was G. rufiventris Schultze & Müller,1857. Later, several other authors described various species exhibiting the “dark dorsal surface and orange or reddish ven-tral side” pattern. These species constitute an assemblage which will be here designated the G. rufiventris-complex. Apartfrom presenting a similar pattern, a further considerable difficulty in differentiating these taxa from the other large, broadand flat species of the genus Geoplana which were included in Froehlich’s original G. applanata-group, resides in theirpossessing a very homogeneous copulatory apparatus. Characteristics of their external and internal morphology are here discussed to simplify the differentiation of sub-groups and comparison of species.

A new species of Araucnephia (Diptera: Simuliidae) from the Northeast Region of Brazil
Authors: PESSOA FELIPE ARLEY COSTA , RÍOS-VELÁSQUEZ CLAUDIA MARÍA , PY-DANIEL VICTOR
Published: April 2019

We describe and illustrate the pupa, larva, and both adults of a new species in the genus Araucnephia Wygodzinsky &Coscarón, 1973 (A. cearensis nov. sp.). The species was found in a highland area in Ceará State, Northeast Brazil. The pupa canbe separated from those of other Araucnephia pupae based on the number of gill filaments, which range from 25 to 35 branches(versus 9 or 14), and by it being completely encased by the cocoon. The larva can be separated from those of other Araucnephiabased on the presence of a median accessory anal sclerite. Adults are typical of the genus. This species extends the northern range of the genus Araucnephia, which is postulated to be Gondwanan in origin.

Redescription of Orthopristis ruber and Orthopristis scapularis (Haemulidae: Perciformes), with a hybridization zone off the Atlantic coast of South America
Authors: MARCENIUK ALEXANDRE PIRES , CAIRES RODRIGO ANTUNES , MACHADO LEONARDO , CERQUEIRA NAJILA NOLIE CATARINE DANTAS , DE S. SERRA RAYLA ROBERTA M. , OLIVEIRA CLAUDIO
Published: April 2019

The genus Orthopristis includes seven valid species, three from the western Atlantic and five from eastern Pacific, while the available identification guides and taxonomic keys incorrectly recognize Orthopristis ruber as the only valid species found on the Atlantic coast of South America. Efforts to expand the inventory of fish species from the northern coast of Brazil led to the identification of two distinct species of Orthopristis from Atlantic South America, based on the analysis of coloration patterns and meristic data, as well as DNA. In the present study, the limits of Orthopristis ruber are reviewed, while Orthopristis scapularis is recognized as a valid species for the northern and northeastern coasts of South America. Based on intermediate morphological characteristics and nuclear DNA markers, a hybrid zone was identified off the state of Espírito Santo, on the eastern Brazilian coast. Additionally, considerations are made on the diversity and biogeography of the coastal marine and estuarine fishes found on the Brazilian coast.

School segregation and residential segregation are generally highly correlated. Cities in the Netherlands are considered to be moderately segregated residentially, while the educational landscape is choice-based but publicly funded. This article analyses how school and residential segregation are interrelated in the educational landscape of Dutch cities. Drawing on individual register data about all primary school pupils in the 10 largest cities, it demonstrates that segregation by ethnicity and social class is generally high, but that the patterns differ strongly between cities. By hypothetically allocating children to the nearest schools, this article demonstrates that even in a highly choice-based school context school segregation is to a large extent the effect of residential patterns. The role of residential trends, notably gentrification, is therefore crucial for understanding the differences in current trends of school segregation across Dutch urban contexts.

Published: April 2019

This article analyzes Turkey's policy response to the health needs of Syrian refugees since 2011. The innovations in immigration health policy cannot be explained solely on the basis of factors exogenous to the health sector, such as the massive arrival of Syrian refugees, the gradual Europeanization of Turkish immigration policy or new funding from the European Union. They also display several stages of endogenous learning driven by a reassessment of problems and reevaluation of preferences by Turkish authorities. The paper aims to explain three successive stages of Turkey's organization of migrant health care services: a pre-institutionalization stage in which existing facilities were repurposed, the establishment of the first dedicated migrant health centers and promotion of partnerships with non-governmental organizations (NGOs), and finally the employment of Syrian medical professionals and the decreasing role of NGOs in migrant health centers following the impact of the 2016 European Facility for Refugees in Turkey.

One of the most significant challenges for an unmanned aerial vehicle (UAV) is to autonomously navigate in complex environments, as the signals from the global positioning system (GPS) are subject to disturbance and interference. To improve the autonomy and availability of the UAV navigation system without GPS, we design a new autonomous navigation system and implement it for real applications in this paper, in which one integrates the inertial measurement unit (IMU), the bionic polarization sensor (BPS), and the air data system (ADS). The BPS can provide effective heading angle measurement, and the ADS is used to output information for continuous velocity and height. The combination of BPS and ADS is a solution the inertial error drift. Kalman filter is selected to estimate the error state of the integrated navigation system based on the measurements from the BPS and ADS, and then the estimation is used to correct the navigation system error in real time. The simulation and experimental results have shown that the new integrated navigation system can perform with high precision and autonomy without GPS signal.
The cost of democracy: The determinants of spending on the public administration of elections
Authors: Clark Alistair
Published: April 2019

Managing the electoral process requires considerable administrative and organizational capacity. Poor performance can lead to voters being disenfranchised and the integrity and legitimacy of elections undermined. Providing sufficient capacity to manage a national electoral process is expensive. Little research assesses how much electoral democracy costs, and what drives those costs. These are crucial questions for democracies, political science and public administration. Using rare comprehensive data from Britain, this article’s major contribution is to begin identifying some of the drivers impacting on the cost of electoral administration in advanced democracies. It presents an overview of influences on spending on electoral administration, before developing a multivariate model utilizing socio-economic, organizational and administrative data on election spending. It finds that costs in an important advanced democracy have been driven in a major national election by the need to provide capacity, notably on the ground close to electors.
Understanding Immobility: Moving Beyond the Mobility Bias in Migration Studies
Authors: Schewel Kerilyn
Published: April 2019

This article suggests that there is a mobility bias in migration research: by focusing on the “drivers” of migration — the forces that lead to the initiation and perpetuation of migration flows — migration theories neglect the countervailing structural and personal forces that restrict or resist these drivers and lead to different immobility outcomes. To advance a research agenda on immobility, it offers a definition of immobility, further develops the aspiration-capability framework as an analytical tool for exploring the determinants of different forms of (im)mobility, synthesizes decades of interdisciplinary research to help explain why people do not migrate or desire to migrate, and considers future directions for further qualitative and quantitative research on immobility.
Self-efficacy of pre-school and primary school pre-service teachers in musical ability and music teaching
Authors: Burak Sabahat
Published: April 2019

Pre-service non-music major teachers deem music and music teaching essential, but they do not perceive themselves to be competent in this field due to various reasons. This research aims to reveal the effects of factors such as gender, age, the year of study they are currently in at university, and musical experience on their self-efficacy in music skills and music teaching. The research was conducted with the participation of 395 pre-service teachers studying pre-school education and classroom teaching in the department of basic education in the faculty of education. The data were collected by employing the self-efficacy scale developed for musical abilities and music teaching. The findings of the research indicate that while the self-efficacy of the participants in musical abilities and music teaching does not show meaningful difference by gender, it does show meaningful difference according to the year they are in at university. According to the regression analyses, the important variables predicting perceived musical ability are music teaching self-efficacy, having previously played an instrument, and currently playing an instrument. However, the variable of music teaching self-efficacy is predicted meaningfully only by musical ability self-efficacy.

Published: April 2019

Latin anatomical terminology of venous perforators (communications between superficial and deep venous systems of the lower limb) was adopted as late as 2001 as an appendix to the official nomenclature following the clinicians’ request. Terminologia Anatomica, last version of the Latin anatomical nomenclature, published in 1998, unfortunately contains no terms concerning these veins. During the 14th World Congress of the International Union of Phlebology, a consensus document was laid to expand the nomenclature of the lower limb veins, above all 36 new terms for perforators of the lower limb, both in Latin and English languages. This consensus document will be incorporated in the next version of the Terminologia Anatomica. But there are more constant and well-described ones, especially in the foot, and this article reviews in particular the current knowledge on the anatomy of the venous perforators of the whole lower limb.

Experimentally induced hypoxia triggers migraine and aura attacks in patients suffering from migraine with aura (MA). We investigated the blood oxygenation level-dependent (BOLD) signal response to visual stimulation during hypoxia in MA patients and healthy volunteers. In a randomized double-blind crossover study design, 15 MA patients were allocated to 180 min of normobaric poikilocapnic hypoxia (capillary oxygen saturation 70–75%) or sham (normoxia) on two separate days and 14 healthy volunteers were exposed to hypoxia. The BOLD functional MRI (fMRI) signal response to visual stimulation was measured in the visual cortex ROIs V1–V5. Total cerebral blood flow (CBF) was calculated by measuring the blood velocity in the internal carotid arteries and the basilar artery using phase-contrast mapping (PCM) MRI. Hypoxia induced a greater decrease in BOLD response to visual stimulation in V1–V4 in MA patients compared to controls. There was no group difference in hypoxia-induced total CBF increase. In conclusion, the study demonstrated a greater hypoxia-induced decrease in BOLD response to visual stimulation in MA patients. We suggest this may represent a hypoxia-induced change in neuronal excitability or abnormal vascular response to visual stimulation, which may explain the increased sensibility to hypoxia in these patients leading to migraine attacks.
Effects of Charging Infrastructure and Non-Electric Taxi Competition on Electric Taxi Adoption Incentives in New York City
Authors: Jung Jaeyoung , Chow Joseph Y. J.
Published: April 2019

With major investments in electric taxis emerging around the world, there is a need to better understand resource allocation trade-offs in subsidizing electric vehicle taxis (e-taxis) and investing in electric charging infrastructure. This is addressed using simulation experiments conducted in New York City: 2016 taxi pickups/drop-offs, a Manhattan road network (16,782 nodes, 23,337 links), and 212 charging stations specified by a 2013 Taxi & Limousine Commission study. The simulation is based on a platform used to evaluate taxi operations in California and Seoul. Eleven scenarios are analyzed: a baseline of 7,000 non-electric taxis, five scenarios ranging from 1,000 e-taxis to 5,000 e-taxis, and another five scenarios in which the e-taxis have infinite chargers as an upper bound. The study finds that the number of charging locations recommended in the earlier study may be insufficient at some locations even under the 3,000+ e-taxi scenarios. More importantly, despite an average revenue of $260 per taxi for the 7,000 non-electric taxis and about $247 per taxi for electric taxis over the finite charger scenarios, the revenue gap between e-taxis and non-electric taxis in a mixed fleet increases significantly as the e-taxi share increases. This is because the increasing queue delay imposed on e-taxis gives non-electric taxis an increasing competitive advantage, raising their average revenue from $260 per taxi (1,000 e-taxis) up to $286 per taxi (5,000 e-taxis, 150% revenue gap increase), all other operating costs being equal. This has implications for individual versus whole-fleet policies, as the individual-oriented policies may be less effective.

Published: April 2019

A blisk is one of the key parts of an aero-engine, whose surface processing quality directly affects aero-engine performance. Different degrees of vibration occur during the process of new open belt grinding which seriously affect the precision of the dimensions and the surface quality of the entire blade profile. With the aim of addressing this problem, this study constructed a physical model of blisk belt grinding, analysed the low-rigidity characteristics of the grinding system, and researched the vibratory mechanism of the blisk belt grinding system based on a dynamic analysis method. In addition, the factors affecting the stability of the grinding process and the stability conditions of the grinding were considered. Then, the belt grinding process of a blade surface was simulated through a numerical method. The technological parameters were quantified for different conditions of the blisk belt grinding vibration. The optimal combination of process parameters was obtained. Finally, the optimised process parameters were validated experimentally. The research demonstrates that vibration from blisk belt grinding is related to the process parameters as follows, in the order of the greatest influence: the grinding pressure, belt velocity, feed speed, and contact wheel hardness. After optimisation, the cross-sectional profile is 0.031–0.041 mm and the surface roughness is 0.1–0.2 μm; the surface is smoother and has better consistency.

Published: April 2019

With the development of autonomous underwater glider technology, the gliders integrated with multitype sensors have been widely applied in the ocean scientific research. Among those sensors, electromagnetic velocity sensor provides a new way to acquire the unknown parameters of Petrel‐II glider. Based on the analysis of computational fluid dynamics, the optimized layout position and distance of electromagnetic velocity sensor is determined. Petrel‐II integrated with electromagnetic velocity sensor conducted a series of sea‐trials to obtain sailing data under different attitudes. By combining sea‐trial data with dynamic model of deepsea glider, the relationships between pitch, hydrodynamic forces/moment, and angle of attack are yielded. The buoyance model in the dynamics is validated by suspension experiment of glider. The dynamic simulations in the longitudinal plane with different hydrodynamic parameters obtained by, that is, optimization with electromagnetic velocity sensor, data statistical analysis combining computational fluid dynamics and parameter identification, and calculation by computational fluid dymanics, are conducted and compared with experimental results to verify validity and accuracy of those parameters. Results show that hydrodynamic parameters optimized by integrating electromagnetic velocity sensor on the glider can exhibit dynamic behavior more accurately. This work contributes to the calculation of vertical water velocities from glider and theoretical research of glider.

Authors: Li Chaoyue , Feng Shiyu , Chen Chen , Peng Xiaotian , Liu Weihua
Published: April 2019

The onboard inert gas generation system with turbocharger (OBIGGSTC) was proposed for better inerting performance of an aircraft fuel tank. The operating principle and method of the system were introduced, and the mathematical model of the major component was deduced. Then, the characteristic of the system was simulated based on the software AMESim. Compared with the traditional onboard inert gas generation system (OBIGGS), the proposed system has the potential advantages of reducing the weight and volume of the air separation system by decreasing the number of hollow fiber membrane modules (HFMMs) from a maximum number of eight to one at 0.3 MPa of the bleed air from the engine. When both inerting systems have a single HFMM configuration, the OBIGGSTC can substantially reduce the inerting time by 66.6% compared with the OBIGGS at 0.3 MPa of the bleed air. Due to the turbine applied, the mass flow rate of the bleed air of the inerting system with turbine is greater than the traditional system. The compensatory loss of the proposed system is less than the OBIGGS by a maximum of 57.39% when the bleed air pressure varies from 0.3 to 0.8 MPa with a range in flight time from 4 h to 10 h. By analyzing the two inerting system, the OBIGGSTC has better performance than the OBIGGS.
Rapid trajectory optimization for hypersonic entry using a pseudospectral-convex algorithm
Authors: Wang Jinbo , Cui Naigang , Wei Changzhu
Published: April 2019

Aiming at improving the autonomy of hypersonic entry vehicles, a rapid trajectory optimization algorithm, which has the potential to be implemented online and onboard, is proposed in this paper. The nonlinear and nonconvex hypersonic entry trajectory optimization problem is transformed into a series of convex subproblems through a proper combination of the pseudospectral method and an improved successive convexification method; thus, the high discretization accuracy of the pseudospectral method and the fast and deterministic convergence properties of the convex-optimization-based algorithm can be simultaneously exploited. The resulting subproblems can be solved efficiently by matured interior-point methods, and the solution converges rapidly by adopting a novel dynamic trust-region updating approach. The optimality of the solution is verified by the optimal control theory. The effectiveness of the algorithm is demonstrated by numerical experiments.
