Abstract
本申请属于航空发动机技术领域，特别涉及一种燃烧室试验件，包括：进气段、试验段与火焰筒；进气段包括：位于进口的速度分布模拟孔板、平直整流段以及等压渐扩段；试验段安装在等压渐扩段后端，试验段尾端安装出口挡板，出口挡板安装出口导管，火焰筒头部通过浮动结构与进气段壁面连接，火焰筒尾部插入出口导管的进口端；出口挡板还安装外引气隔板与内引气隔板；外引气隔板、试验段和出口挡板形成外引气隔腔，内引气隔板、试验段和出口挡板形成内引气隔腔，外引气隔板与内引气隔板具有进气孔，试验段上具有将外引气隔腔，内引气隔腔气体排出的排气通道；所述进气孔分布模拟真实发动机气孔，能够有效实现热补偿，解决机匣与火焰筒膨胀不协调问题。
