A multifunction integrated power unit (MIPU) (10) for use aboard aircraft provides the functions both of an auxiliary power unit and of an emergency power unit while being smaller, lighter, and less expensive than the two units it replaces. Additionally, the integration of both functions in a single unit allows elimination of duplicated service devices and a further reduction in size, cost, and weight in the aircraft itself. The MIPU (10) includes two turbine engines (12, 22) operable under differing conditions, an integrating gear box (34) receiving pow...


A combined auxiliary and emergency power unit comprising: a gear box; energy producing equipment mechanically coupled to said gear box to be driven when said gear box is provided with a rotary power input; first and second turbine wheels for producing said rotary power input; first and second clutches respectively coupled to said first and second turbine wheels; a rotary compressor connected to said first turbine wheel to be driven thereby and for providing a compressed air source; a first combustor for receiving fuel and compressed air from said compres...
