,A Short Review on Electric Aircraft Development and Futures, Barriers to Reduce Emissions in Aviati |
Selcuk Ekici,Alper Dalkiran,T. Hikmet Karakoc |
|
Abstract
Electric aircraft are being proposed as a solution to climate change and global warming, as they do not produce greenhouse gas emissions, which are harmful to both humans and the environment. Electric aviation is expected to reduce operating and maintenance costs, reduce fuel costs, and bring financial advantages. Hybridization is the process of reducing the amount of fossil fuel needed in aircraft propulsion systems by providing both electric and gas turbine engines. Hydrogen-powered propulsion systems are an alternative to hybrid systems that can directly use hydrogen as a fuel, but are not included in range limitations. Electric aircraft may be powered autonomously by a flying aircraft to reduce noise pollution and pollutants, and improved measuring methods or procedures should be defined to support noise legislation and community noise effect.

,Design Considerations for Hybrid-Electric Propulsion Systems for FW-VTOL Aircraft, |
Daniele Obertino,Phillip Sharikov,Jay Matlock,Afzal Suleman |
|
Abstract
This paper aims to present the ongoing research effort on hybrid-propulsion unmanned aerial vehicles (UAVs) carried out at the University of Victoria Centre for Aerospace Research (UVIC-CFAR). The study involves the development and updating of an optimization framework capable of evaluating vertical takeoff and landing (VTOL) and conventional takeoff and landing (CTOL) unmanned aerial vehicle (UAV) hybrid propulsion performances, with a recent focus on more unconventional configurations mounting fuel cells onboard. A preliminary sizing and mass analysis for the hybrid propulsion system of a UAV with VTOL capabilities was accomplished. A similar analysis was also performed for a CTOL configuration powered by hybrid fuel cell schemes. Finally, a hybrid test bench used to validate the models and test the components is presented. The paper concludes with the general statement that for small UAVs, a hybrid power plant can lead to improvements in endurance, fuel consumption, and efficiency along the mission.

,Influence of Battery Aging on Energy Management Strategy, |
Teresa Donateo,Ludovica Spada Chiodo,Antonio Ficarella |
|
Abstract
In the context of Hybrid Electric Propulsion Systems, one of the main aspects to investigate is the most suitable energy management strategy, which would allow the objectives of fuel consumption minimization and electric backup availability to be attained. The present study aims at comparing two different energy management strategies for a Hybrid Electric air-taxi vehicle: although both are based on the same set fuzzy rules, the first one has been implemented neglecting battery aging effects, while the second adjusts the optimal battery discharge according to its age. The impact of such adaptation on fuel consumption and battery state of charge is evaluated along a typical mission profile.

Delia Teresa Sponza,Nefise Erdinçmer |
|
Abstract
In this study, the impact of the leather industry to the environment was studied by the utilization of a Life Cycle Assessment protocol. An inventory for life cycle analysis (LCA) was carried out. This inventory contains the energy, the wastes discharged to the receiving media in a limited matrix containing all the inputs and outputs of the leather industry. The methodology of this mass-balance inventory is an accepted estimation for assessment of the environmental factors relevant to the sustainable operation of leather industry. The environmental impacts were evaluated for leather industry based on inputs (raw materials, energy recovery) and emissions of the environmental waste and wastewater as outputs.

,Resampling Based Particle Filter Estimation of a Quadrotor, |
Aziz Kaba,Ahmet Ermeydan |
|
Abstract
Quadrotors have dynamic nonlinearities, coupling effects and unstable open-loop characteristics. Control of quadrotors are still an open issue. Flight controllers need the sensor outputs to calculate the attitude angles. However, unmanned aerial vehicles are prone to sensor noises and disturbances. To control a quadrotor, its states must be effectively estimated. So, in this work, resampling based particle filter is presented and effect of particle size is investigated for attitude estimation problem of a quadrotor.

,Electric Aircraft: Motivations and Barriers to Fly, |
Paul Parker,Chelsea-Anne Edwards |
|
Abstract
Electric aircraft became a certified aviation option in 2020, but will stakeholders make it a market success? The new technology offers several potential benefits that motivate adoption, including reduced greenhouse gas emissions, reduced noise and reduced operating costs. However, barriers such as technology uncertainty, limited battery capacity/endurance and the dominance of existing fossil fuel technologies may limit the adoption of e-planes. The rate of adoption of this technology in the first target market, flight schools, will depend on the perceived strengths of these benefits and barriers among key stakeholders: student pilots, instructors, managers/owners, and others. This study provides insights from 186 survey respondents. The top motivation to fly e-planes differed across cohorts as student pilots rated reduced emissions highest while instructors and flight school managers rated reduced costs for training as their strongest reason. Managers also rated the benefits of quieter operations and reduced accident risks more highly than other stakeholders. Battery endurance and the continued dominance of fossil fuel technology were rated as the strongest barriers to adopting e-

Victoriia Khrutba,Inessa Rutkovska,Tatiana Morozova,Lesia Kriukovska,Natasha Kharitonova |
|
Abstract
The paper proposes a list of criteria for environmental impact assessment in construction and reconstruction projects of transport facilities. The list of criteria includes impact on the quality of the surface layer of atmospheric air; volume of consumption of non-renewable resources; impact on the quality of the aquatic environment; waste management efficiency indicator; impact on the quality of land resources; impact on the quality of the geological environment; physical factors influencing the environment; impact on flora and fauna, protected objects; impact of TF on the social environment; impact of the transport structure on the man-made environment. Each of the criteria is a set of local indicators. The method of quantitative evaluation of these criteria has been developed, which provides for expert evaluation of each criterion according to the proposed scale. The method was implemented during the environmental impact assessment of the project “Construction of a state road H-31 Dnipro – Tsarychanka – Kobeliaky – Reshetylivka from the village of Loboykivka to the border of Dnipropetrovsk region I-b technical category with 4 lanes bypassing Loboykivka, Petrykivka, Mohyliv, Kita

,Two-Phase Heat Exchangers for Thermal Control of Electric Aircraft Equipment, |
Leonard Vasiliev,Alexander Zhuravlyov |
|
Abstract
Thermal control systems based on two-phase heat transfer devices providing efficient removal of excess heat from cooled objects are considered. The heat pipes and thermosyphons are autonomous and noiseless. Their operation does not require energy consumption. These devices can take heat from the object to be cooled, remove it outside the volume filled by the equipment, and then transfer it to the coolant or air. The attractiveness of two-phase passive heat transfer for use in electric and hybrid aircrafts is noted. With a help of heat pipes and loop thermosyphons it is possible to equalize the battery temperature by transferring heat from its modules to a liquid cooling system. A possibility to successfully remove heat from a rotor and stator of an electric motor is analyzed and discussed. A rotor of an electric engine can be cooled using rotating centrifugal heat pipes (vapor chambers). The heat pipe cooling system is attractive due to its simple and reliable design, moving parts absence, and the relatively low weight of the device.

Utku Kale,Omar Alharasees,Joszef Rohács,Dániel Rohács |
|
Abstract
In aviation working environment it is really important that operators (Pilots, ATCOs) make optimum judgments and a timely decision under different subjective work scenarios, which is influenced by a variety of factors such as skills, experience level, and the human response factor. By applying a novel generalized model that employ the operator’s environmental and physical conditions, the study explored the endogenous dynamics of the pilot abilities of decision-making under varied experiences and skills using the modified Lorenz attractor on MATLAB for modelling for comparing the subjective decision-making of pilots for the following experience levels: (i) pilot cadets, (ii) less-skilled pilots, (iii) skilled pilots, and (iv) expert pilots. For two flight tasks: landing and go-around circumstances, the “hesitation frequency” and “decision-making time” were calculated during the final approach. In addition, this research investigated several specific aspects of operators that influences the aviation safety.

,Acoustic Operational Monitoring of Unmanned Aerial Vehicles Near Vertiports, |
Vitalii Makarenko,Vadim Tokarev |
|
Abstract
Operational safety will become of a prime concern, as many of UAS would fly close to residential areas. This paper is devoted to small UAS (sUAS) collision risk with static ground objects in populated zones. Solutions of sense and avoid problem involve the use of a passive localization method to detect collision threats. This method uses the acoustic signature of the UAS. The method is based on resampling of received signals of moving UAS for Doppler shift compensation, evaluation of generalized cross-correlation with phase transforms and signal delays grouping using cyclic sums and products.

,Test Bench for Electric Propellers and Distributed Propulsion, |
Castroviejo Daniel,Patrick Hendrick |
|
Abstract
In the quest for a sustainable aviation many new innovations are taking place while other old technologies are being revised. Such is the case of distributed electric propulsion. For this type of technology (the same used as on the NASA N3-X (Felder JL, NASA N3-X with turboelectric distributed propulsion (2014, November). https://ntrs.nasa.gov/archive. Accessed 10 Jul 2020) for instance), ducted propellers are used to increase overall efficiency and aerodynamic performance of the aircraft. It is no doubt that electric distributed propulsion has some advantages (Kim HD, 27th International Congress of the Aeronautical Sciences at NASA Glenn Research Center, Distributed Propulsion Vehicles, 2010; Kim HD, Felder JL, Brown GV, Turboelectric distributed propulsion in a hybrid wing body aircraft, 2011) over classic propulsion configurations such as for instance improved maneuverability, control surfaces area reduction and hence weight reduction, boundary layer ingestion (Friedrichs J, Budziszewski N, Energies 11, Modelling of a boundary layer ingesting propulsor, 2018) and more. In this paper it is the effect of the duct over the propeller efficiency which will be quantified. To do so, a

,Aircraft Accidents and Their Causes, |
Samer Al-Rabeei,Simona Pjurová,Utku Kale |
|
Abstract
The number of accidents with fatal consequences is falling lower with each decade since 1950s, which is noteworthy accomplishment if we consider the constantly growing frequency of air travel. While in 1949, there were 40 fatal accidents in total per one million departures, during the next decades this number significantly dropped to less than two accidents per one million departures. According to IATA, civil aviation safety is still on the lowest rate in history based on current number of accidents per one million departures. This improvement in safety is based on a number of factors. Reliability of jet engines has huge impact on this safety. Other than that, improvements in sensors, navigation, and air traffic control technology are one of these factors too. Finally, reducing human error during crew and cockpit management and data monitoring is one of the most important improvements in recent decades. The aviation industry’s remarkable record of safety during the last years is mostly thanks to big technological leaps during the second half of twentieth century.

,Solar-Electric Long Endurance Reflector Craft for Meteorology and Climate Simulation, |
Narayanan M. Komerath,Ravi Deepak,Adarsh Deepak |
|
Abstract
Combating climate change requires temporally and spatially-resolved atmospheric and solar data planetwide. The Glitter Belt HALE architecture of reflective vehicles serves both as meteorology platforms and as a scalable, reversible option to reduce insolation. The 30.5 km altitude and 12-h night glide requirements, rendezvous, and swarm operation for high-precision distributed antenna applications all pose unique challenges, but are shown feasible with the present approach. Conceptual design, small scale design-build-fly tests, and dynamic flight simulation are used to remove uncertainties and derive system properties.

,Examination of Different Systems Used for UAV Detection and Tracking, |
Alpaslan Durmuş,Erol Duymaz |
|
Abstract
The use of unmanned aerial vehicles (UAV) has increased rapidly in recent years and has become widespread. The reason for this is that UAV systems are cost-effective compared with many aircraft and their maintenance costs are relatively lower. Of course, the prevalence of UAV systems in our daily lives in such a short time brings security threats. In recent years, different systems have been used to prevent security threats from UAV systems. These systems are classified as radar systems, acoustic detection technologies, radio frequency (RF) emission detection applications and electro-optical (EO) detection methods. These systems have different advantages and disadvantages. In this study, UAV detection and monitoring applications that can be used to prevent security threats that may arise from UAV systems, which are expected to become more widespread with the stretching of regulations in the next five years, are examined. At the same time, the advantages and disadvantages of different UAV detection and tracking applications were examined and tips were presented to the designers.

,Misunderstandings in Aviation Communication, |
Omar Alharasees,Abeer Jazzar,Utku Kale |
|
Abstract
The consequences of ineffective communication can be life-threatening and dramatic. Communication misunderstandings are often cited as the cause of paranormal events in aviation which could lead to accidents/incidents. As a result, the risk of lack of communication is relatively high. Many factors that directly or indirectly influence the rate of misunderstandings in communication, such as language barriers, non-standardized phraseology, ambiguous communication, regional differences, and premature communication, are the causes of communication errors in flight. The study focuses on distinguishing and emphasizing various perspectives of communication and making suggestions to operators to reduce misunderstandings in aviation communications. The study is based on a survey highlighting the important communication loads such as flight training, standard expressions, operator’s native language, and cultural background. The survey collected 110 responses from pilots and ATCOs, from various countries, with approximately 20% being ATCOs and 75% being pilots. Some suggestions concluded based on the results of this study are (i) improving aviation training by further focusing on radiotelepho

,Modeling of Exhaust Gases Jet from Aircraft Engine for Different Operational Conditions, |
Kateryna Synylo |
|
Abstract
Emission inventories analysis at European and Ukrainian airports highlighted that aircraft is a dominant source of air pollution. To evaluate the aircraft contribution in airport air quality, it is important to consider some features of the aircraft, as a special source of air pollution. For the most part of landing-take-off cycle, the aircraft is maneuvering on the ground, and it is subjected to fluid flow that can create a strong vortex between the ground and engine nozzle, which have essential influence on structure and basic mechanisms of exhaust gases jet from aircraft engine. The paper demonstrates the results of CFD modeling and analysis for the jets close to ground surface, simulating the aircraft engine jets’ performances in airport. The numerical simulation of wall jet by Fluent 6.3 was implemented for different combination of initial jet velocity and height of engine installation to evaluate the influence of the ground on jet’s parameters (height and longitudinal coordinate of buoyancy effect, length of jet penetration). Obtained results provide improvement of PolEmiCa model.
