在假定燃油泄漏的情况下,发动机加力燃烧室外侧二次流通道内存在失火的可能性。不同的喷油方式,不同的喷油量和不同的二次流速度对失火有一定的影响。本试验研究对飞机空中失火的故障分析有一定的帮助。
Under the assumption of fuel leakage, there is a possibility of misfiring in the secondary flow passage outside the engine afterburner. Different injection methods, different injection quantities and different secondary flow rates have a certain impact on misfire. This experimental study has some help to the aircraft fault analysis in the air.
