Model-based Failure Anticipation and Predictive Maintenance: a Landing Gear Application
Authors:   Airbus Helicopters, Rocher Antonin ,   INSA Toulouse, Maré Jean-Charles , Becquet Roland
Published: October 2022

In order to reduce maintenance for the operators and improve the availability of their aircrafts, new failure anticipation methods are being implemented at Airbus Helicopters. This paper focuses on the rapid development and entry into service of a monitoring and alerting algorithm able to provide a diagnosis for the most common faults encountered in-service on a landing gear system. This development is based on a hybrid approach combining analysis on historical data and multiphysics modelling and simulation. Reliable health indicators are built to greatly reduce the amount of data to be continuously analyzed from in-service measurements. The monitoring of their values assesses the system health and diagnoses a potential on-going degradation mode. The implementation of such methods aims at paving the way for a condition-based maintenance on aircraft on-board systems, given the promising results and operational gains already exhibited by the in-service implementation.
Probabilistic Damage Estimation for Rotorcraft Condition-Based Maintenance
Authors:   Georgia Institute of Technology, Musso Dakota , Rogers Jonathan
Published: October 2022

Predicting the probability of dynamic component failure in aircraft is of interest to both civilian and military operators for safe and cost-effective component retirement. While aircraft OEM assumed usage spectra have been used throughout the years for fatigue forecasting and for creation of part replacement timelines, advancements in aircraft regime recognition and instrumentation have made it possible to track the portion of consumed useful life in lifelimited components based on actual usage. This paper introduces a novel approach to condition based maintenance (CBM) that is designed to be used in conjunction with a probabilistic regime recognition scheme. The proposed methodology results in a probability distribution of incurred damage for specified life-limited components on an individual aircraft basis, with applications to fleet-wide probabilistic damage spectrum. The primary advantage of the proposed methodology is the rigorous treatment of regime uncertainty that is quantified in probabilistic regime recognition. A Gaussian probability density approximation is used to improve computational efficiency of the damage estimation method, and effects of the flight condition on the uncertainty in the damage estimation are investigated. Following a detailed explanation of the proposed methodology, results are provided by applying the algorithms to simulated data for the SH-60B and compared against a rule-based approach for individual aircraft damage tracking.
Predicting a Maximum Stress using Machine Learning and Parametric Flight Data
Authors:   Mercer Engineering Research Center, Sweet Michael , Forgerson Samuel , DeMontfort Chad
Published: October 2022

Mercer Engineering Research Center (MERC) developed a neural network-based regression method for predicting maximum stress per flight values at four structural tracking locations on the United States Air Force HH-60G helicopter airframe using Individual Vehicle Health and Usage Monitoring (IVHMS) data. Maximum stress per flight is utilized when evaluating a failure criterion within the HH-60G service life analysis, so an accurate, fleet-wide estimation of maximum stress magnitude and likelihood is critical for accurate service life determinations. The model was trained using parametric flight data time histories (from IVHMS) and stress time histories from a strain survey aircraft. The stress time histories were developed from the strain signals using two different methods depending on the location of strain gauges in the vicinity of the tracking locations. For two of the tracking locations, they were derived from a global finite element model using a collection of strain gauge signals throughout the strain survey aircraft. At the other two tracking locations, the strain time histories were derived from single strain gauges installed in close proximity to the tracking locations. Multiple regression methods and input data configurations were evaluated in order to identify an appropriate regression method that predicts a maximum stress per flight accurately without over-fitting the training data. MERC identified that the relationship between parametric flight data and aircraft component strain can be exploited to a high level of accuracy using machine learning regression tools. Achieving a high level of accuracy required an extensive review of independent and dependent variable data quality and thoughtful consideration of model inputs.
Unified Statistical Framework for Rotor Fault Diagnosis on a Hexacopter via Functionally Pooled Stochastic Models
Authors:   US Naval Test Pilot School, Geyer William , Gordon Barbara , Mattei Christopher , Robinson Dwight
Published: October 2022

In this work, a statistical time series method that is capable of effective multicopter rotor fault detection, identification, and quantification within a unified stochastic framework is introduced. The proposed framework is based on the functional model based method for fault magnitude estimation tackled within the context of statistical time series approaches. Estimator uncertainties are taken into account, and confidence intervals are provided for the fault magnitude of multicopter rotors. The framework employs functionally pooled (FP) models which are characterized by parameters that depend on the fault magnitude, as well as on proper statistical estimation and decision-making schemes. The validation and assessment is assessed via a proof-of-concept application to a hexacopter flying forward with a constant velocity under turbulence. The fault scenarios considered consist of the front and side rotor degradation ranging from healthy to complete failure with 20% fault increments. The method is shown to achieve fast fault detection, accurate identification, and precise magnitude estimation based on even a single measured signal obtained from aircraft sensors during flight. Furthermore, fault quantification is addressed via the use of both local ( boom acceleration) and global (IMU) sensors, with the signals collected from the boom supporting the identified faulty rotor proven to achieve better performance than the global signals, yet with a shorter signal length.
Effect of load limiting control on rotorcraft maneuver performance and component damage growth
Authors:   Georgia Institute of Technology, Shah Aarohi , Mballo Chams , V. J. , Rimoli Julian
Published: October 2022

Control strategies for damage mitigation of rotorcraft components and consequently their life extension mainly take the form of Load Alleviation Control by reducing peak-to-peak component dynamic loads. This results in a conservative approach and also has a significant effect on maneuver performance. Load limiting control offers an opportunity to overcome this challenge, provided an effective strategy is used to select which harmonic load should be limited and by how much. In this work, we study the sensitivity of a localized damage parameter to limiting different harmonic loads by introducing a damage mitigation control metric, which we call the integrity ratio that also includes information about the effect of load limiting on the maneuver performance. We use a surrogate model for damage prediction and a load limiting control scheme to analyze the integrity ratio by conducting open-loop simulations. We also conduct threshold sensitivity studies to identify an appropriate threshold measure for load limiting. Our findings indicate that limiting the harmonic load with a higher integrity ratio helps in reducing damage growth along with preserving the maneuver capability. Depending on the allowable effect on maneuver, this metric can enable a less conservative damage-driven control strategy for extending the operational life of a component.
Floyd Carlson: The Legacy and Contributions of One of America's Greatest Rotary Wing Test Pilots
Authors:   US Army (Retired), Fardink Paul
Published: October 2022

Floyd Carlson was a true pioneer and major contributor in the early development and testing of a broad-range of cutting-edge vertical flight aircraft. His contributions are numerous. Starting with the birth of Bell Helicopter in Gardenville, New York (1942-1945), he performed the first flight of every helicopter Bell designed and built until 1960. His biography mirrors the early history of Bell Helicopter. During this time, Carlson became one of the most experienced and renowned helicopter test pilots in the world, testing aircraft which included the Model 30 (1942); Model 47 (1945); HSL-1 Tandem Rotor Helicopter (1953); XV-3 (1955), forerunner of the XV-15 and V-22 Osprey tiltrotors; and XH-40 (1956), prototype of the iconic UH-1 “Huey.” Floyd Carlson’s passion for aviation began with the guidance of his older brother Milton, whose tragic accident and death left an enduring impact on Floyd’s life as he continued to develop and master the techniques of vertical flight.
History of the Vertol Aircraft Corporation, 1956 to 1960
Authors:   Boeing Vertical Lift (Ret.), Bartie Kenneth
Published: October 2022

With an overall company lifespan of only four years, Vertol Aircraft Corporation continued the tandem-rotor helicopter legacy of its predecessor, Piasecki Helicopter Corp., as well as research, development and testing of other V/STOL aircraft and technologies while concurrently designing two medium-lift transport helicopters that are still in worldwide use and/or production today. During this short timeframe, the company finalized production and deliveries of the H-21C Shawnee/V-44 for the US Army and international customers. The company designed and flew the world’s first tilt-wing VTOL, the NACA/Army/Navy/Vertol VZ-2A. Application of T53 and T58 turbine powerplants led to twin-turbine engine trials and flight tests with experimental H-21 variants. With Vertol’s in-theater customer support, the French Army and Navy introduced the H-21 into combat in Algeria which included the early use of armed, troop-carrying helicopters. The design, test and successful US and worldwide demonstrations of the privately-funded Vertol 107 led to development and certification of the 107-II airliner version and follow-on military transports as the Boeing H-46 Sea Knight. The contract to design and build the YHC-1B was won by Vertol in 1959 and led to the enduring Boeing H-47 Chinook.
Preserve, Educate and Inspire - Founding the American Helicopter Museum and Education Center
Authors:   American Helicopter Museum, Beggs Robert
Published: October 2022

The American Helicopter Museum and Education Center opened to the public at the Brandywine Airport on October 18, 1996. This milestone was the realization of a vision adopted at a luncheon meeting hosted by the Philadelphia Chapter of the American Helicopter Society on July 30, 1993. Chapter leaders had previously brainstormed potential ideas for commemorating the upcoming 50th Anniversary of the American Helicopter Society in 1994, but recognized the need to engage a broader constituency to do something significant. With the goal of establishing a 50th Anniversary Committee, a luncheon was scheduled at Boeing Helicopters in Ridley Park, PA. Participants included the author, several Chapter officers and an invitation list that included Philadelphia area rotary-wing business leaders, industry pioneers and influencers. Attendees at that first meeting included Lee Douglas, Frank Duke, Vincent Genovese, Euan Hooper, Warren Jacobs, Wes Moore, Ren Pierpoint, John Schneider, George Townson, Edward B. Wilford III and Peter Wright, Sr. After debating multiple options for the commemoration, the idea of a museum was embraced when Peter Wright, then President of Keystone Helicopters, offered to donate several vintage helicopters if a museum was established. Two weeks later, the nascent 50th Anniversary Committee met again with a mission to: “Lay the foundation for a permanent rotary-wing restoration, conservation and exhibition facility in the Delaware Valley.”

Referencing the documented minutes of the aforementioned meeting and that of subsequent meetings of the 50th Anniversary Committee, other documents and the recollections of the author, this paper will trace the formative years of the museum from July 1993 to October 1996. It will address the many challenges of founding an aviation museum including incorporation, location identification, building the collection and creating the exhibits and programs. It will recall the people involved and their significant contributions. This paper is particularly compelling to publish this year, recognizing the 25th anniversary of the American Helicopter Museum and Education Center on 18 October 2021.
Use of Uncertainty Quantification to Determine the Impact of Manufacturing Error on the Handling Qualities of Tiltrotor Aircraft
Authors:   University of Glasgow, Yuan Ye , Anderson David , Thomson Douglas
Published: October 2022

The tiltrotor aircraft has unique flight dynamics characteristics and handling qualities due to its multiple unique designs. However, these designs may lead to additional manufacturing errors, and these uncertainties may play a significant effect on the flight dynamics and handling qualities. Therefore, this article combines a validated flight dynamics model of tiltrotor aircraft with the uncertainty quantification method to evaluate the manufacturing errors effect on the flight dynamics characteristics and handling qualities criteria, including eigenvalues and bandwidth and phase delay results. The manufacturing errors include the blade chord length, rotor radius, blade stiffness, rotor pretwist, nacelle incidence angle, and the aerodynamics uncertainties of the fuselage, wing, and tailplane. Besides, the variance-based sensitivity analysis is introduced here to assess the effects of different manufacturing errors on the trim characteristics, stability derivatives, and controllability derivatives. The results indicate that: i). the manufacturing errors would influence the handling qualities results in the longitudinal channel, especially during the helicopter mode or high-speed flight ranges. ii). The rotor radius would alter the trim and stability and controllability results across the flight ranges, and the effect of other components (wing, fuselage, and tailplane) are more significant in the conversion and airplane mode.

Many applications in intelligent transportation systems are demanding an accurate web
application-based location prediction. In this study, we satisfy this demand by designing an automated
mobile user location prediction system based on the well-known traditional Auto-Regressive Integrated
Moving Average (ARIMA). To increase the proposed model accuracy, make it dynamic, and reduce its
execution time, the traditional ARIMA model has been modified extensively by using different combinations of
design options of the model. To perform user location prediction, the proposed model depends the previous
recorded user locations to predict the user future locations. To make the proposed model dynamic, it is
designed to regenerate all its parameters periodically. To deal with such dynamic environment, only a
specified window of the historical data is used. To reduce the regeneration of the model execution time, the
model selection process is enhanced and several model selection approaches are proposed.
The proposed model and the different design options are evaluated using a realistic user location dataset
trace that are recorded using a WIFI embedded, as well as, using traces from a previous study called the
Kaggle Dataset. To deal with any imperfection in the data used in generating the model in this study. The
results show that the proposed framework can generate ARIMA models that can predict the future user
locations of a user accurately and with a reasonable execution time. The results also show that the proposed
model can predict the user’s location for several future steps with an acceptable accuracy.

Authors: Omodero Cordelia Onyinyechi
Published: October 2022

It has become imperative that subnational governments in the Nigerian federal system faithfully represent their tax autonomy and statutory receipts through their developmental efforts. The influence of states’ independent revenue initiatives and vertical allocations on capital spending is investigated in this study. The analysis spans from 2000 to 2019nd counted on secondary data from the Central Bank of Nigeria’s Statistical Bulletin. The goal of this work is to explore how much tax income generated by states and allocated from the federation account influences infrastructure development in Nigeria’s 36 states, as well as the Federal Capital Territory (FCT) of Abuja. The point is that economic development can only be achieved if the fiscal decentralization in the country characterized by revenue and expenditure responsibilities is well maximized. Thus, the study uses multiple regression techniques to arrive at the empirical results, which indicate that the states’ tax efforts do not express tangible improvement in infrastructural development. On the other hand, the result also highlights that the statutory apportionment to the states significantly affects states’ capital projects. Summarily, the study recommends conducive business vicinity and commitment of the government to provide public goods and services required by the citizens.

Feet Don’t Fail Me Anymore! Single-Centre Results Using Low-Dose Radiation Therapy for Feet Inflammatory Disorders and Review of Current Evidence
Authors: Montero Angel
Published: October 2022

Background: Plantar fasciitis- and tendinopathy-related foot pain are common cause of functional disability. Low-Dose Radiation Therapy (LDRT) has proven to be effective in the symptomatic relief of these disorders.

Material and methods: Between February 2016 and December 2021, 31 patients were included in this prospective register. Seventeen patients suffered from calcaneodynia, 11 from tendonitis and 3 from osteoarthritis. 6 Gy (1 Gy/fraction) or 3 Gy (0,5 Gy/fraction) were delivered and repeated after 12 weeks if no adequate relief. Response was evaluated at the end of the planned courses, after 3 months and subsequently every 6 months using Visual Analogic Score (VAS), the Von Pannewitz Score (VPS) and daily analgesic drug needs.

Results: Overall, 87% of the patients experienced pain relief. Patients with a VAS score above 5 dropped from 35.5% at the end of LDRT to 32%, 13% and 6% after 3, 6 and 12 months, respectively. According to the VPS, 74% showed improvement and 26% remained stable. Lastly, 39% of patients stopped or reduced analgesic intake. Nine patients have been followed up for more than 12 months. The median pre-treatment VAS score in this group was 9 (range 7-10), whereas median VAS scores after 3, 6 and 12 months stood at 5 (range 1-7), 3 (range 0-6) and 1 (range 0-6), respectively (Fig. 2). An improvement in functionality was reported by 7 out of 9 individuals (77.7%). No acute or late complications were observed.

Conclusion: LDRT appears to be useful for symptomatic treatment of inflammatory and degenerative disorders of the foot.

RESULTADOS: Se obtuvo una muestra de 63 pacientes, de las cuales; 45 recibieron manejo médico (Grupo 1), 10 manejo quirúrgico mediante histerectomía obstétrica (Grupo 2) y 8 manejo quirúrgico conservador mediante ligadura de arterias uterinas combinado con B-Lynch modificado (Grupo 3). La técnica empleada en las pacientes si mostró evidencias significativas de riesgo, por ejemplo; los casos con histerectomía representaron prolongada estancia hospitalaria (p=0.000), mayor requerimiento de paquetes globulares (p=0.000) y riesgo de letalidad significativo (p=0.004). CONCLUSIONES: Los manejos quirúrgicos conservadores, como el utilizado en este estudio mediante sutura compresiva por la técnica de B-Lynch con la modificación realizada más la ligadura selectiva de las arterias uterinas por la técnica de Posadas si mostró efectividad en el control de la hemorragia obstétrica por atonía uterina, por lo que dicha técnica se puede recomendar como opción terapéutica escalonada, más no como primera línea de tratamiento.

The growth of companies, non-production companies and nations is often linked to quantitative evaluations that, in reality, do not show real growth in the global sense of the entity on which attention is focused. This is why the title of this article is that growth does not always mean growth. Growth requires evaluating a series of quantitative and qualitative elements in the absence of which growth is not, in reality, real growth in the global sense. The issue, posed in these terms, could have been the subject of a multivolume work covering all the various facets of the concept of corporate and state growth. This is not our objective. For this reason, in this article, we will address issues that simultaneously concern both enterprises and non-production companies, private and public, and nations. Only the simultaneous observance of all these principles, which will be analysed in the following pages, can be said to be a first step towards real growth, even if, as we have already pointed out, the global concept of growth would require an in-depth analysis of topics that are not the subject of this work.
