摘要：
The Space Shuttle Orbiter currently uses three hydrazine-fueled auxiliary power units (APUs) to provide hydraulic power for the vehicle aerodynamic surface controls, main engine thrust vector control, landing gear, steering, and brakes. Electric APUs have been proposed as possible replacements to the hydrazine APUs. Along with the potential advantages, this paper describes an electric APU configuration and addresses the technical issues and risks associated with the subsystem components. In addition, characteristics of an electric APU compared with the existing APU and the direction of future study with respect to the electric APU are suggested.
