摘要

The dramatic increase of power and energy density in electric systems has enabled practical application of battery-powered model aircraft and unmanned vehicles. This will soon enable practical electric man-carrying aircraft including VTOLs. These vehicles can take advantage of a new system paradigm of distributed pathways for electric power, shaft power and sensing/control signals such that reliability and safety are not compromised. All elements in potential future electric prime-power systems have wide application and thus there exists industry-wide evolutionary pressure to improve performance and reliability of batteries, power-dense alternators, power-dense motors, drive trains, conductors, power semiconductors, monitoring systems and controllers. This paper presents results of a preliminary NASA-Sponsored effort conducted by M-DOT Aerospace to identify potential failure modes of a man-rated VTOL aircraft power system and to generate resultant designs that accommodate failure modes through redundancy of critical-path elements. The effort consisted of identification and ranking of failure modes of a notional system, identification of possible design solutions, construction of reliability models and finally, preliminary design and solid modeling of several potential power trains. A common feature of all power trains was an electric motor with multiple separate stator windings such that one or more could fail without loss of aircraft.
