All Electric Cooling System for Unmanned Aircrafts

Journal of Aerospace Sciences and Technologies, 2023
This study brings out two All Electric Environmental Control System (AE-ECS) configurations for Unmanned Aircraft air-conditioning and performance evaluation of these two configurations interms of power consumption and fuel mass penalty. In conventional (or traditional) Bleed Air System, hot air is extracted from the engine compressor whereas in Bleed ...

Flight management systems for all-electric aircraft

2017 IEEE Conference on Control Technology and Applications (CCTA), 2017
Recent years have marked a significant step forward in the development of all-electric airplanes, some of which have been built and tested recently. This paper proposes an optimal control framework for flight management systems of all-electric aircraft. The optimal control problems of economy mode and maximum endurance will be solved using Pontryagin's

Advanced aircraft electrical systems to enable an All-Electric aircraft

2015 International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles (ESARS), 2015
Efficient power generation techniques used in a modern aircraft are described in the form of a High Voltage Variable Frequency Starter Generator. Its advantages in enabling an All-Electric aircraft are discussed. Machine Design aspects of such a system are obtained from detailed analysis of the output equation of a high speed rotating machine.

All-electric aircraft

Power Engineer, 2003
While there are many technical challenges to overcome before a fully electric aircraft is operational, the benefits of such a system are significant. For the industry to move forward the More Electric Aircraft and its partner concept, the More Electric Engine (MEE) must become reality in the next 10 to 20 years.

All Electric System Architecture for Aircraft and Propulsion

52nd Aerospace Sciences Meeting, 2014
This paper describes a system architecture for future All Electric Aircraft (AEA). The proposed AEA system integrates electrical power management, which uses an HVDC grid system to control supply and demand of electrical power, and thermal management, which provides adjustable cooling of power electronics with an autonomous air-cooling system.

Electromechanical Actuation Technology for the All-Electric Aircraft

IEEE Transactions on Aerospace and Electronic Systems, 1984
Electromechanical actuation is a critical element that must be developed and verified to make the all-electric aircraft a viable concept. For several years the Flight Control Division of the Air Force Wright Aeronautical Laboratories has sponsored activities to demonstrate the credibility of electromechanical actuation systems (EMAS) for primary flight

HTS Machines for Applications in All-Electric Aircraft

2007 IEEE Power Engineering Society General Meeting, 2007
Environmental preservation has now become paramount as natural resources are rapidly consumed. A global reduction of the emissions of pollutants in the atmosphere is therefore needed and new technologies have to be considered. A large part of the emissions rejected in the atmosphere comes from transportation vehicles, including cars, trucks or ...
