Abstract
Duplication of engine and secondary power system components in individual auxiliary and emergency power units is avoided in an integrated power unit including a gas turbine engine 10 having a centrifugal compressor 28 and a turbine 40, a generator 18 coupled to the engine 10, an air inlet 22 to the compressor 28, a first reservoir 82 for combustible fuel, and a first combustor 34, 36 for receiving and combusting compressed air from the compressor 28 and fuel from the reservoir 82 to generate gases of combustion and feeding the gases of combustion to the turbine 40 by the provision of a second reservoir 80 for containing a compressed oxidant for combusting fuel from the first reservoir 82, a second combustor 48 for receiving and combusting fuel from the first reservoir 82 and oxidant from the second reservoir 80 to generate gases of combustion, flow paths 64, 66, 68 for introducing fuel from the reservoir 82 into the gases of combustion from the second combustor 48 to vaporize the fuel and a conduit 50, 52 for directing the combined gases of combustion and vaporized fuel to the turbine 40 to drive the same. The apparatus is useful as an auxiliary power unit when the combustor 34, 36…
