JET ENGINE, MISSILE AND JET ENGINE OPERATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a jet engine capable of preventing reduction in thrusting force of the jet engine due to reaching of a high pressure region to an inlet, a missile and an operating method for the jet engine.SOLUTION: A jet engine 2 comprises a plurality of fuel injectors including a first fuel injector 20 and a second fuel injectors 30, 30A and a plurality of flame holders including a first flame holder 22 and a second flame holders 32, 32A. The first injector 20 in the plurality of fuel injectors is arranged at the upper-most stream side. Fuel injection control units 90; 90A; 90b; 90C are constituted in such a way that a first operation mode in which at least the second fuel injectors 30; 30A are set to the operation state and a second operation mode in which at least the first fuel injection unit 22 is set to the operation state can be selectively executed. A rate of fuel injection amount injected from the first fuel injection unit 20 with respect to a total amount of fuel injection TA injected from the plurality of fuel injectors in the second operation mode is larger than that of the first operation mode.SELECTED DRAWING: Figure 5C
