Combustion instability not only affects the stability of the aero-engine work, but also caused the combustion chamber flame tube thin-walled structure acoustic-vibration coupled fatigue.
燃烧不稳定不仅影响航空发动机的工作稳定性，而且还是造成燃烧室火焰筒薄壁结构声振耦合疲劳破坏的重要原因。
The conclusion points out that the ripples appeared in the laminar microgravity V flame are due to the effect of acoustic interaction coupling with the harmonic instability.
因此，微重力环境下V型火焰锋面的不稳定性可能是声波与谐波相耦合的结果。
