Abstract
Difficulties in starting a gas turbine engine at high altitudes may be avoided by the method of starting such an engine which includes the steps of introducing fuel into the combustor (26) of the engine through at least one fuel injector (46) having an outlet (76, 78) within the combustor (26), atomizing the fuel with a burst of oxidant at elevated pressure from a source (92) of pressurized stored oxidant until ignition is obtained, and thereafter discontinuing the burst of oxidant from the source (92).
