Development and Flight Demonstration of Energy Regeneration System for Aircraft

Abstract

The development of energy regeneration system and the result of flight demonstration were described in this paper. The regeneration system was designed and integrated to regenerate potential energy of aircraft to electric energy. The autors experimentally clarify the conditions to maximize regeneration efficiency. The display system and a power lever included as pilot interface in the system are configured to adjust the regenerated power without any increase of pilot workload. As the result of test flights in 2015, functions of the system are properly demonstrated and succeeded to realize stable `Regenerative Soaring' for the first time in the world.
