摘要

分析了燃气发生器和高温放气阀的作用及必要性，阐述了两者的设计思路，提出了有关的设计原则，并根据该原则设计研制出了满足技术指标的燃气发生器和高温放气阀.对两者进行一系列试验，验证了设计原则的正确性.结果表明：燃气发生器在最小空气流量为0.025kg/s，最高燃气工作温度为950℃，燃气温度波动范围为±10℃，实现稳定工作；高温放气阀在1200℃时能实现不漏气、灵活可靠的工作.上述技术指标均高于我国目前地面上使用的、车用的同类试验设备.利用该两项试验设备，可准确、完整地得到涡轮增压器特性，为实现航空活塞发动机的优良高空性能提供了依据.

Abstract

The design thoughts of gas generator and high-temp gas release valve were introduced

and their design principles were developed and confirmed experimentally. The experimental results show that

the gas generator can work steadily in the environment where the air mass flow rate is 0.025kg/s

the work temperature being up to 950℃

and the fluctuation of combustion temperature being ±10℃

and high-temp gas release valve has the characteristics of no leakage at 1200℃. The indexes above are higher than those of experiments for vehicles and grounds. Using the gas generator and high-temp gas release valve

the turbocharger characteristic can be obtained accurately and completely

helping to realize optimum altitude performance of state of art aero-piston engine.
