The invention belongs to the technical field of aircrafts, and discloses an aviation auxiliary power device and an aircraft. The aircraft comprises an aviation auxiliary power device, the aviation auxiliary power device comprises a power converter, a starting permanent magnet motor, a floating spline shaft and a turbine gas generator, and the power converter is electrically connected with the starting permanent magnet motor. The starting permanent magnet motor comprises a rotor shaft and a stator assembly, the stator assembly is arranged on the periphery of the rotor shaft in a winding mode, the rotor shaft is connected with a main shaft of the turbine gas generator through the floating spline shaft, and the starting permanent magnet motor is used for starting the turbine gas generator. The turbine gas generator can drive the starting permanent magnet motor to generate power when running to a full rotating speed. According to the aviation auxiliary power device, the rotor shaft is connected with the main shaft, the starting permanent magnet motor can be driven to generate electricity when the turbine gas generator runs to the full rotating speed, and the electricity utilization requirement of an aircraft is met.
