摘要

Method for starting an engine of a helicopter gas turbine powered by a circuit of combustu00ecvel, supply circuit for a camera combustu00ecvel combustion of an engine of a helicopter gas turbine, and gas turbine engine helicopter.A method of departure of a helicopter gas turbine engine comprises: feeding at least one (40a) of the injector main motor, forming an injector main departureDirectly through a feeding tube for pressurized fuel (32); impose a load loss (valve 36) between the feeding tube and the other main injectors; cause that ignition takes place in the injector main departure; and, after the ignition.To eliminate the loss of burden between the feeding tube and the other main injectors (through the valve opening (38) so that all of the main injectors are fed with fuel at substantially the same pressure, without any loss of load imposed.The invention also relates to a circuit of the fuel supply to implement the method and a helicopter gas turbine engine that has such a circuit.
