整流支板和火焰稳定器的一体化设计及性能分析

Frame plate and flame holder integration design and capability analysis

针对航空发动机高推质比、高隐身的需求,提出一种加力燃烧室整流支板和火焰稳定器一体化设计的方法,并开展了相关模型加力燃烧室的计算和试验研究.研究结果表明:采用一体化设计加力燃烧室,能够缩短加力燃烧室长度,大幅降低非加力状态的冷态流阻,明显改善发动机加力燃烧室的性能,提高发动机的推质比.可为解决高推质比、高隐身发动机技术提供了一种新的思路和研究方向.

Based on the increasing demand for high thrust weight ratio and high stealthy aero-engine,the design method of integration design frame plate and flame holder afterburner was given and some model afterburner simulations and experiments were conducted.The results show that the length and can flow resistance could be reduced greatly,and the capability and thrust weight ratio of aero-engine can be increased apparently.This work would help to provide a new research direction and method for high thrust weight ratio and high stealthy aero-engine technology.
