Abstract:
The influence of the velocity of the decomposed hydrogen gas on the abnormal flameout of the hydrogen peroxide-low concentration ethanol gas generator was analyzed by experi— ment and simulation．The analysis shows that the velocity of the decomposed gas of hydrogen plays a key role on whether the gas generator works normally after ignition．When the injection pressure drop of the decomposed gas is 1．OMPa．the velocity of the decomposed gas is∞hi．gh that the flanle can not stay in the combustion chamber,the gas generator extinguishes abnormally；if the injection pressure drop reduces to 0．2MPa,the velocity of the decomposed gas is lower,the gas generator works normally．
