Title: Starting of turbine engines

Abstract

This patent describes a relatively small turbine engine. It comprises: a rotary turbine wheel; a rotary compressor coupled to the turbine wheel; an annular combustor for receiving air from the compressor and fuel from a fuel source combusting the same and providing gases of combustion to the turbine wheel to drive the same; substantially identical main fuel injectors including fuel injecting nozzles angularly spaced about the compressor; fuel and air from the compressor being introduced into the combustor generally in the tangential direction; a fuel pump; a control schedule valve; and first and second main fuel solenoid valves. The first valve being operable to connect a minority of the injectors to the control schedule valve and the fuel pump for starting the engine, there being an even number of the injectors and the minority of injectors consisting of two diametrically opposite injectors; the first and second valves being operable to connect all of the injectors to the control schedule valve and the pump for causing normal operation of the engine; the engine further being characterized by the absence of start fuel injectors for the combustor.
