摘要
本文提出的探测航空发动机主燃烧室熄火的方法,是以发动机转速下降率作为判别主燃烧室熄火的指示参数。在FADEC控制系统中,该方法只需在控制软件中增加一小段计算程序,无须添加额外的硬件设备。论文设计了原理试验样机,并在发动机试车台上进行了试验验证。
A method to probe engine main chamber outfire in the paper regards engine rational speed drop rate as a indicating parameter to identify main chamber oulfire.The method demands only to add a little block of calculation programme in the FADEC control system,and does not demand additional any hardware.A test prototype has been designed in the paper and has been demonstrated on a engine test rig.
