固体燃气控制阀内流场参数计算

Analysis on the flow field parameters of a solid pro- pellant hot-gas valve

对用于飞行器横向机动控制的固体推进剂燃气控制阀的内流场参数进行了初步分析。通过二维轴对称模型的数值求解,得到了控制阀在运动过程中活塞体两个典型位置的流场参数分布,可为工程研制提供参考。

The preliminary analysis is made on the internal flow field parameters of a solid propellant hot-gas valve for maneuver control of flight vehicles. The distributions of flow field parameters of two typical piston positions in the valve are obtained based on the numerical analysis on a 2-D axial symmetrical model. It is available for reference in engineering developments.
