Abstract
A flight vehicle includes a fuselage and a gas turbine engine. The gas turbine engine is coupled to the fuselage to provide thrust when air surrounding the flight vehicle is admitted to the gas turbine engine and combusted with fuel. The flight vehicle further includes a generator coupled to the gas turbine engine to provide power to equipment included in the vehicle.
Claims17
A flight vehicle comprising:
- a fuselage including a nose and a tail spaced apart from the nose,
- a gas turbine engine located in a space formed in the fuselage and located between the nose and the tail, and
- a generator unit coupled to the gas turbine engine via a generator shaft, at least a portion of the generator shaft located exterior to the generator unit and the gas turbine engine, to cause a portion of the generator unit to rotate therewith, the generator unit being located in spaced-apart relation to the gas turbine engine between the nose and the gas turbine engine,
- wherein the flight vehicle further includes an air inlet duct coupled to the gas turbine engine and formed to include an air passageway therein and an air inlet defining an aperture opening into the air passageway to communicate air surrounding the flight vehicle through the aperture, through the air passageway, and into the gas turbine engine for combustion,
- wherein a portion of the generator unit extends into and lies in the air passageway.

A flight vehicle comprising
- a fuselage including a nose and a tail spaced apart from the nose,
- a gas turbine engine, comprising a compressor and a combustor, located in a space formed in the fuselage and located between the nose and the tail, and
- a generator unit coupled to the gas turbine engine to cause a portion of the generator unit to rotate therewith, the generator unit being located in spaced-apart relation to the gas turbine engine between the nose and the gas turbine engine,
- wherein the flight vehicle further includes a first air inlet duct formed to include a first air passageway, a second air inlet duct spaced apart from the first air inlet duct and formed to include a second air passageway, and a common duct interconnecting the first and second air inlet ducts and the gas turbine engine and formed to include a common air passageway therein in fluid communication with the first and second air passageways, and a heat exchanger in the generator unit extending into one of the first air passageway, the second air passageway, or the common air passageway.
