ABSTRACT:
Difficulties in starting turbine engines 10 at high altitudes are avoided in a starting system which includes a combustor 34 having a gas outlet 32 adapted to be in communication with a turbine engine nozzle 28, a fuel inlet 36, and an oxidant inlet 38 so that fuel may be oxidized within the combustor 34 by an oxidant to provide hot gases at the outlet 32. The system includes a first pressure vessel 58 adapted to receive liquid oxygen and a second pressure vessel 60 adapted to receive liquid nitrogen. Pumps 62, 64, and conduits 56, 54, 68 establish a flow path between the vessels 58, 60 and the oxidant inlet 38 while a mixing valve 66 is disposed in the flow path to mix the oxygen and nitrogen flowing therein in a desired proportion.
