Authors:   University of Texas at Austin, Mortimer Patrick ,   Technical University Munich (TUM), Platzer Stephan , Sirohi Jayant , Rauleder Juergen
Published: July 2023

A hovering two-bladed, 2-m-diameter rigid rotor was used to investigate the effects of dynamic pitch inputs at multiple blade loading coefficients. Unsteady rotor loads and the flow field were measured using an internal load cell and time-resolved particle image velocimetry, allowing for inflow, tip vortex trajectories and strength to be measured. Two sets of measurements were performed with an image acquisition rate of 44/rev: constant pitch angle (CT/σ = 0.06, 0.08, 0.10), and measurements with dynamic pitch ramp inputs (Δθ0 = 1° amplitude change over four rotor revolutions) at CT/σ = 0.06 and 0.08. The measurements at constant pitch angle and with dynamic pitch inputs were performed over 670 rotor revolutions, in both cases yielding statistically converged averages. In addition, the experiment was simulated using a finite-volume CFD solver. The results were correlated to the experimental data to assess the accuracy of the flow simulations and to gain further insight into the flow phenomenology. Vortex trajectories and axial velocities (inflow and wake) correlated well, and the tip vortex strength was slightly underpredicted by the CFD. From measurements and predictions, it was found that (independent of the thrust setting) the axial velocity in the rotor plane steadily increased to the value after the pitch input. Furthermore, vortex trajectories were little affected by the increased thrust and inflow. The vortex strength revealed trends similar to the axial velocity and gradually increased to the values after the pitch ramp input.

Authors:   NASA Langley Research Center, Boucher Matthew , Christian Andrew , Krishnamurthy Siddhartha , Rizzi Stephen
Published: July 2023

A psychoacoustic test was performed that aimed to test how well Sound Exposure Level (LAE) is at indicating changes in annoyance to helicopter noise for simple changes in design as well as for realistic changes found from flight tests. In particular, LAE was evaluated for auralizations of optimized designs of rotor geometries when compared to a baseline design and for recordings that compare different helicopters and maneuvers. Paired comparisons consisted of the 10dBA-down portion of flyovers, which is the same portion used to calculate LAE. When played at the same LAE, annoyance responses showed in which cases LAE is a good indicator as well as when other aspects not included in the calculation of LAE may be important. Annoyance responses for relative differences in LAE allowed the calculation of an Equal Annoyance Point, giving further insight to the performance of LAE. Confidence intervals calculated with Monte Carlo simulations showed when responses are statistically different from the equal LAE comparison and also gave an indication of the necessary reduction for designers to be confident that a low noise design is impactful or that a difference in rotorcraft or maneuver is perceptually favorable.
Aeroacoustic Analysis of a Side-by-Side Hybrid VTOL Aircraft
Authors:   University of California Davis, Jia Zhongqi , Lee Seongkyu
Published: July 2023

This paper investigates the acoustics of a side-by-side Urban Air Mobility (UAM) aircraft with 0%, 5%, 15%, and 25% rotor overlaps in forward flight based on high-fidelity Computational Fluid Dynamics (CFD) simulations. The CFD and acoustics simulations are carried out using the HPCMP CREATETM-AV rotorcraft simulation and analysis tool Helios and the acoustic prediction tool PSU-WOPWOP. The influence of the finest wake-grid spacing size on acoustic prediction of the side-by-side rotor with 0% overlap is studied based on two wake-grid spacing cases: 5% Ctip and 10% Ctip. No significant difference in overall sound pressure level (OASPL) is found between the two cases. The effect of rotor overlap on rotor acoustics is also assessed, and it is shown that the 25% overlap case yields higher OASPL than the other overlap cases particularly due to stronger rotor-to-rotor blade-vortex interactions (BVIs). Furthermore, the noise of the side-by-side rotor with 0% and 25% overlaps is compared against similar-sized helicopter noise and various background noise levels. It is shown that the side-by-side rotor noise is comparable with the noise of a similar-sized four-bladed helicopter in cruise. The OASPL difference of the overhead case is less than 10 dB, which does not meet the guideline that the UAM noise should be 15 dB lower than similar-sized helicopter noise. The results also show that the side-by-side rotor noise could not be fully masked by the freeway background noise at an altitude of 1,500 ft. Thus, noise reduction technology should be developed to overcome the barrier of public acceptance of UAM noise.

Published: July 2023

Acoustic characteristics of two- and four-bladed rotors with a 1.108 m radius in hover were measured experimentally at rotor speeds up to 1200 RPM and tip Mach number up to 0.41. The Rotorcraft Comprehensive Analysis System (RCAS) using a viscous vortex particle method (VVPM) coupled with PSU-WOPWOP were used to simulate the acoustic characteristics of the same rotors. Simulations were also conducted for a stacked rotor over a range of azimuthal spacings with zero axial spacing. PSU-WOPWOP predictions included thickness, loading, and broadband noise. Both experiments and simulations showed that broadband noise was the dominant contributor to A-weighted sound pressure level at a distance of 8.25 radii from the rotor center. Simulations showed a sharp increase in the broadband and overall noise at higher thrust, but the experiments did not show such an increase. Higher harmonic components of the tonal noise were nearly as large as the blade passage frequency noise in the experiments, but were underpredicted in the simulations by up to 30 dB. Simulations incorporating wind showed closer agreement in the higher harmonic tonal components. The unweighted overall sound pressure level in the stacked rotor simulations showed 5 dB to 10 dB variations with azimuthal spacing, but the A-weighted tonal and overall SPL was insensitive to azimuthal spacing.
Computation and Extraction of Boundary Layer Parameters from Numerical Simulations for Use in Rotor Acoustics Models
Authors:   University of Maryland, Costenoble Miranda ,   US Army CCDC Army Research Laboratory, Hrynuk John , Baeder James , Singh Rajneesh
Published: July 2023

Low-order rotor broadband noise models require the boundary layer, displacement, and momentum thicknesses around the rotor's component airfoils to be provided. This data is often unavailable from prior literature, and may not be accurately computed (if at all) by simplified aerodynamics codes. To obtain the boundary layer thicknesses, this study builds on an integrated and robust meshing and solution approach using HAM2D, a Navier-Stokes computational code with advanced flow transition computations. This approach using HAM2D is already used to compute airfoil performance tables, and the computation of the boundary layer thicknesses imposes negligible additional overhead. The boundary layers computed by HAM2D are validated against prior data and wind tunnel PIV measurements conducted specifically for this study. In general, HAM2D shows good agreement with both experimental data sets, particularly with the PIV measurements conducted for this study, and where HAM2D diverges from historical data, so too do the PIV measurements. A few specific points of disagreement are noted, and future work will seek to reduce these inconsistencies.

Published: July 2023

An extensive flight test campaign was recently completed, which aims to reduce the operational noise generated by helicopters in an effort to improve community acceptance. Using a ground-based microphone array, acoustic measurements were acquired on helicopters in the medium-sized vehicle weight class over a number of flight conditions including steady level flight, steady descents, and approaches. While data were collected across four helicopters, the Leonardo AW139 and Sikorsky S-76D will be the focus of this paper. Source noise hemispheres are computed for the steady test points, but the ground noise contours measured during approach conditions cover only a small portion of the area impacted by noise because of practical constraints on the size of the deployed array. Thus, the Noise Informed Community Environment Operations Planning System (NICEOPS) in conjunction with the flight test data was used to estimate how changes in the approach procedures impact noise exposure over a larger ground area. It was found that even small longitudinal accelerations can have a substantial influence on the noise generation processes during approach and must be modeled appropriately to develop new flight procedures which minimize the acoustic impact on the ground.
CFD and Aeroacoustic Analysis of Wingtip-Mounted Propellers
Authors:   University of Maryland, Jayasundara Dilhara , Baeder James , Jung Yong
Published: July 2023

The wingtip-mounted propeller configuration is widely used in many aircraft, especially with the emergence of urban air mobility. This study focuses on analyzing the aeroacoustic properties of this configuration by understanding the aerodynamic interaction between the propeller and wing. Computational Fluid Dynamics based on Reynolds Averaged Navier-Stokes equations was used to calculate the flow field and the aerodynamic loads on a wingtip-mounted propeller model and were compared with experimental data for validation. The resulting surface pressure was fed as input data for the acoustic analysis performed using a Ffowcs-Williams Hawkings equation-based acoustic solver at multiple angles of attack. It was observed that the presence of the wing significantly increases the propeller noise along the rotational axis. As the angle of attack increases, the propeller noise increases further. However, the wing noise decreases with the angle of attack due to propeller wake dissipation, leading to only a small increase in the maximum total noise.
A Comparison of Multicopter Noise Characteristics with Increasing Number of Rotors
Authors:   Rensselaer Polytechnic Institute, Smith Brendan , Gandhi Dr. , Niemiec Dr.
Published: July 2023

This study examines the acoustic behavior in hover of manned-size, multi-rotor, eVTOL aircraft in the classical quadcopter, hexacopter and octocopter configurations. The rotors are assumed to have collective pitch control and operate at a specified RPM, with orthogonal and tip-to-tip rotor phasing considered. All configurations have the same disk loading and tip Mach number, with the rotor radius decreasing and RPM increasing, going from the quadcopter to the octocopter. The simulations use the Rensselaer Multicopter Analysis Code (RMAC) for the aerodynamic loads on the blades, coupled to PSU-WOPWOP for predictions of propagated noise. From the simulation results, orthogonal phasing between rotors is shown to produce significant noise reductions along inter-boom bisectors (between 9-14 dB relative to an equivalent single rotor, at 6lb/ft2 disk loading and 0.51 tip Mach number). Further reducing the tip Mach number not only reduces the propagated noise but produces even deeper regions of quiet along the inter-boom bisectors (18-25 dB quieter at 3lb/ft2 with 0.36 tip Mach number). An examination of the overall sound pressure frequency spectra indicates that smaller faster spinning rotors (going from the quadcopter to octocopter) produce more tonal peaks at higher frequencies which results in penalties in A-weighted noise.

Published: July 2023

The valuable extract of bioactive compounds from Gynura procumbens has been widely manufactured into various health products. The demand for these compounds is continuously increasing, but production through conventional farming methods is insufficient due to limited agricultural land and environmental stresses. An alternative to producing plant biomass is in vitro cultivation methods. This method requires less space and enables biomass propagation in a controlled condition that can facilitate stable and efficient production of plant secondary metabolites. This study evaluated the effect of inoculum subculture periods and culture methods on G. procumbens biomass and secondary metabolite production in a bioreactor. The 3-L airlift balloon type-bubble bioreactors was modified in this study to adopt the treatment of 1st-5th subculture periods and fed- and batch-cultivation strategies. We found the G. procumbens adventitious root culture was optimally derived from the 1st subculture produced biomass of 148.02±1.45 g FW and 8.59±0.12 g DW, and TPC (14.48±1.08 mg GAE/g DW) and TFC (116.89±0.44 mg KE/g DW and 33.97±0.13 mg QE/g DW). Additionally, the fed method after 28 days of culture using double distilled water replenishment improved adventitious root biomass (213.75±35.00 g FW and 11.21±0.18 g DW), while nutrient replenishment improved TFC (52.14±0.44 mg KE/g DW and 14.54±0.13 mg QE/g DW). These results can be used to optimize the cultivation of G. procumbens adventitious roots in a large-scale bioreactor.

Published: July 2023

Improvements in locomotive wheel-motor unit (WMU) design over the last decade have been made in terms of the transition to rolling motor-axle bearings (MAB) instead of plain bearings, which was the basis for the proposed study.

   The study is aimed to provide a theoretical estimation of power losses in different types of locomotive WMU MAB and its validation depending on heating temperature and bearing specifications.

   The study is aimed to determine power losses in MABs using new approaches to their determination.

   New methods of determining the power losses in the plain and rolling MABs of locomotive WMUs are suggested. These methods allow calculating the values of power losses depending on the specifications of MAB and its heating temperature. Depending on the bearing heating temperature, recommendations are provided with regard to operating conditions of a particular type of locomotive WMU bearing. It is recommended to operate motor-axle plain bearings in the temperature range of 10 to 20 °C, and rolling bearings from 20 °C and above. The suggested methodologies for calculating power losses of locomotive WMU MABs can be used to determine the energy efficiency of a given drive type, taking into account the type of the grease, its temperature, design features and operating conditions. The obtained results can serve as recommendations for the selection of the type of MAB.

The Voters Behavior Towards Women Candidates in the 2019 Legislative Election in North Luwu Regency
Authors: Ananda Rezky Wibowo
Published: July 2023

The results showed that the absence of female candidates who passed the legislative body in North Luwu Regency showed that the implementation of the policy affirmative action of the 30 percent quota of women's representation was not optimal, even though voter behavior was no longer significant in questioning gender issues in politics. This is due to the dominance of male political elites which still have a big influence because the voting community still sees the existence of these political elites. In addition, it is due to the failure of political parties to regenerate and build political commitment to women. Although in the 2014-2019 period there were two female representatives in the legislative body of North Luwu Regency, in the 2019-2023 elections they were not re-elected because they no longer had a network of power and kinship. The most crucial factor is that money politics is still a compromise tool in the electoral process, political actors play a role in money politics, so this makes no female candidates elected because of their inability to compete with the flow of money politics even though they have incurred political costs. which is not the least. Voters will choose a certain candidate if he feels there is a reciprocal that will be accepted as well as political candidates who are afraid of losing their votes, this irrational act (playing money politics) becomes the last resort.

Moral education is a part that cannot be separated from religious education, because what is good according to morals is also good according to religion, and bad according to religious teachings is also bad for morals. Morals in Islamic life are not just a model or a lifestyle that a Muslim may abandon at any time. Morals are not clothes that can be worn and then removed whenever desired. However, morality is a functionalization of religion, meaning that diversity will be meaningless if it is not proven by morality. Strengthening moral education in today's modern era is very important to fortify generations from the negative influence of the development of science and technology, especially information technology which can all be accessed through smartphones. This study aims to formulate moral education to fortify generations from moral decline.

This research is a library research, to build a concept or theory that becomes the basis of study in research. The data used in this study is qualitative data in the form of concepts, theories, and formulations that are relevant to the research made. The data analysis used is content analysis and descriptive analysis to analyze the culture of the Gayo community related to moral education.

The results of the research related to strengthening moral education in the culture of the Gayo community, among others, through strengthening the value system of Gayo culture in society and through strengthening the application of Sumang and Kemali concepts in Gayo culture.

Published: July 2023

The paper seeks to investigate how the state, specifically the Department of Trade and Industry's Bayanihan COVID-19 Assistance to Restart Enterprises (CARES) program, responds to women's economic struggle and how Filipina entrepreneurs make use of the internet for ICT-based business as a solution for income-generating means and sales during the COVID-19 economic struggle. The research locale covers the experiences of online Filipina Entrepreneurs during this pandemic in the Philippines' Region VII, Central Visayas. The research is a qualitative and descriptive case study that uses a purposive sampling technique for data collection utilizing a researcher-made questionnaire and their experiences are analyzed using Colaizzi’s method. In our investigation, we found out that the pandemic has a detrimental effect on women’s businesses, from causing large losses in income and necessitating other sources of income to cover these losses. In solution, these women have entered into an online-operated business employing various marketing strategies to keep their businesses running. Fortunately, there is a consensus that entering in the online business has been a great economic opportunity and helped foster feelings of independence and financial freedom. However, despite this, challenges with internet connectivity in transacting with the government and customers have been a great obstacle and disadvantages such as; increased competition, the possibility of fraudulent transactions, and lack of transportation services experienced- all of which necessitate a systematic solution from the government.  As a recommendation, the research's output is an innovative strategic governance framework integrating two vital aspects: Information and Communications Technology (ICT) and Gender and Development (GAD). Finally, the Philippines' new governance framework combines ICT-GAD to strengthen digital technologies and gender equality in addressing economic challenges. This breakthrough framework marries stale-led finance and individual-based gathering initiatives championed by one of the most vulnerable sectors in society — women.

Published: July 2023

The telecommunication industry faced a negative headwind due to the emergence of OTT (over the top) services, resulting in lower service prices, limited network-based services, and increased network capex. This led to a scissor effect, with significant growth in capex and stagnant revenue growth. In Indonesia, telco operators attempted to enter the digital economy market but failed to increase revenue. To address this, European operators spun off the service telecommunication company (ServeCo) and the telecommunications network provider company (InfraCo, NetCo, and FiberCo), a strategy in the consolidation of the telecommunications industry. The largest telecommunications company in Indonesia is currently conducting a diversification strategy review to encourage growth by leveraging its market leadership in the FTTH (Fiber to the Home) business. This study calculates the business potential and valuation of each potential scenario implemented by Telkom using DCF and conducts a decision analysis using the AHP method to determine the most appropriate scenario. After calculating the projections and valuation, the authors conduct interviews with experts to weigh each criteria required and targeted by Telkom for analysis using AHP.

Indonesia is a country that has very diverse natural resources, one of which is spices. Various kinds of spices such as cloves, nutmeg, ginger, turmeric, candlenut, pepper, cinnamon, and vanilla are what make Indonesian spices known worldwide and contribute to the country’s economy. Clove is a typical Indonesian spice originating from the Maluku islands (Ternate and Tidore). Currently, cloves have been cultivated in various regions in Indonesia, namely Java, Central Kalimantan, East Kalimantan, Sulawesi, and others. Clove season in Indonesia occurs once or twice a year, namely from April to May and October to November. The farmers will harvest ripe clove flowers, then the clove flowers are dried in the sun and processed as raw materials for the production of cigarettes, cosmetics, and others. CV. Rempah Jaya is one of the leading and best clove suppliers in Indonesia. Especially variations of cloves such as whole cloves, clove oil, dried clove leaves, dried clove stems, and clove ash. Usually, the supply of cloves to the cigarette factory is held every few months in large quantities, so a lot of spare time is available before sending it to the factory. Therefore CV. Rempah Jaya needs the right work to be done when there is a time vacuum. The purpose of this study is to increase the time utilization of CV companies. Rempah Jaya during the clove harvest interval. In this study, a situation analysis was carried out using the Kepner-Tregoe method, then external and internal analysis was carried out using Mendelow’s Matrix and SWOT Analysis methods. After that, root cause analysis was carried out using Ishikawa Diagram. Then the decision-making process is carried out using the Analytical Hierarchy Process (AHP) method. From the results of the AHP method, alternative values were obtained for the three available criteria, namely oil distillation, spice mixtures, and collaboration with the food and beverage industry with values of 0.64, 0.19, and 0.17.

This paper presents a research study focusing on investor behaviour patterns and decision-making processes when selecting investment products and exploring alternative options, P2P lending and gold saving. The study also explores the potential attractiveness of banking as an investment option if banks can offer alternative products that are currently not available within the banking sector through collaborative banking with FinTech companies. By understanding investors’ perspectives and addressing their pain points, companies can propose solutions and develop effective marketing approaches that cater to their needs. The research methodology employed a qualitative approach, involving in-depth interviews with ten respondents selected through purposive sampling. Data analysis was conducted using NVivo software. In conclusion, alternative investment products generate enthusiasm among investors as they offer convenience in managing their portfolios in one banking platform. Banking is perceived as the safest place to put the money compared to other investment platform. However, for banks to successfully cater to customer needs, it is crucial for banks to provide a user-friendly interface, performance review that allows for daily monitoring of investments, clear product info and tutorials, as well as protection for high-risk products like P2P lending.

Script for the Balinese people is not just a symbol of sound, but is considered a symbol of the birth of knowledge which is commemorated as Saraswati day. Deeper than that, the script is a symbol of Ida Sang Hyang Widhi Wasa and His manifestation. This study aims to reveal the theology of script in the Saiwasogata religion in Bali. The research data was collected through literature study, and analyzed by symbol theory. The result of this research is the script used to represent Saiwasogata theology in Bali. These scripts include the Pre-Nagari script and Pallawa script derivatives, namely Old Bali and New Balinese script. Currently, the New Balinese script is used more to represent Saiwasogata theology, classified into Wréastra, Swalalita, and Modré scripts. Based on the results of the analysis it can be stated that the script is used as a symbol to express the concept of divinity and the religious teachings of Shiwa and Buddha. In the Kasogatan religion in Bali, it is used to express the Tathāgata concept, using sacred scripts from éka scripts to Buddhist tenets and mantras that explain the Buddha as the true truth. The Buddha through his dharma advised that humans try to defeat māra and try to reach nirwana. In the Shiwaist religion, the script is also used as a symbol of God, including manifestations. This script is used as a medium to understand the essence of Shiwa Tattva. This concept is explained using sacred scripts from ékaksara to sodasaksara and mantras that explain Shiwa Tattva, is the philosophy of divinity and the universe. An understanding of Shiwa Tattva is needed so that Atmika Tattva tries to realize his own purity as a spark of God in order to achieve true happiness or moksha.
