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

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.

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 ...

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

Poster: All-Electric Ground Operations for More Electric Aircraft

2022
Raising awareness about environmental issues shifts the aerospace industry towards electrification and the corresponding solutions are already present from the airport perspective. Commercial aircraft are the missing links in claiming the all-electric ground operations. They rely on fossil fuels without any electric alternative due to the technological

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.

Flight Safety Issues of an All-Electric Aircraft

IEEE Transactions on Aerospace and Electronic Systems, 1984
Flight safety issues of an all-electric aircraft include flight control system reliability, protection from electromagnetic interference and lightning, and protection from design errors (primarily in software) and handling qualities when failures occur if the all-electric aircraft does not have traditional aerodynamic stability. Some of these questions
