The concept of avoiding complete loss of thrust by a multiplexed motor system was proposed for the purpose of reducing the accidents due to engine failure of single engine aircraft. The developed multiplexed motor system consists of four motor elements and can provide totally 60 kW power. Even if one motor element loses the power during takeoff and climb, the aircraft can safely continue to climb due to the output of 45 kW from the remaining motor elements. The pilot can maneuver with the same feeling as in the conventional aircraft without any discomfort in the multiplexed motor system. The motor system and the pilot interface were mounted on a demonstrator and manned flight tests were conducted. This paper describes about the summary of flight tests in FEATHER (Flight-demonstration of Electric Aircraft Technology for Harmonized Ecological Revolution) project at JAXA and discusses the design method of the multiplexed motor system for aeropropulsion.
