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.
