Abstract
Aspects of this disclosure relate to externally accessible auxiliary power unit (APU) pump assembly, comprising: a pump configured to pressurize an accumulator that is used to start an APU of an aircraft; a pressure gauge for the accumulator; and a support frame configured to be mounted within an outer wall of the aircraft, wherein the support frame defines an externally accessible compartment and secures the pump and the pressure gauge within the externally accessible compartment.
Claims20
A system for externally providing pneumatic/hydraulic pressure for an auxiliary power unit (APU) of an aircraft, comprising:
- a pump configured to pressurize an accumulator that is used to start the APU of the aircraft, wherein the accumulator is located within a ceiling of the aircraft and the pump is located within an externally accessible compartment at a rear portion of the aircraft behind a main cabin of the aircraft;
- a removable pump handle used to actuate the pump;
- a pressure gauge for the accumulator;
- and
- a support frame mounted within an outer wall of the aircraft at the rear portion of the aircraft behind the main cabin, wherein the support frame defines the externally accessible compartment and secures the pump, the removable pump handle, and the pressure gauge within the externally accessible compartment.
