加力燃烧室是现代航空发动机的主要部件,主要用于短时间发动机推力的加大及飞机机动性的增强。加力点火器的点火快速性和燃烧稳定性,特别是在低压、高速下的迅速点火以及点火高度,将对整个发动机的性能和可靠性产生很大影响。本文计算的加力点火器是长明灯式的预燃室点火器,其优点在于当发动机处于加力状态时,加力点火器始终为工作状态;尤其是在高空飞行状态,可确保加
Afterburner combustion chamber is a major component of modern aeroengine, mainly for a short period of time to increase engine thrust and enhance aircraft maneuverability. Ignition fastness and combustion stability, especially in low pressure, high speed rapid ignition and ignition height, will have a great impact on the performance and reliability of the entire engine. In this paper, the afterburning igniter is a beacon-type pre-chamber igniter, which has the advantage that when the engine is in the state of afterburner, the afterburning igniter is always in the working state; especially in the high-altitude flight state,
