Abstract:
The failure mode of an engine is analyzed and the model of a corresponding part is established in this paper based on the phenomenon of low-frequency combustion instability occurred in hot fire testing of the engine. The phenomenon of the low-frequency unstable combustion was eliminated after the design improvement of a corresponding part.
