nozzle throat area

influence of gas generator nozzle throat area on missile launch power

燃气发生器喷喉面积对导弹发射动力的影响

Results show that pintle could change the nozzle throat area and thus the motor pressure and thrust, which provided the capability for thrust control.

结果显示喉栓能够有效改变发动机燃烧室压力和推力，满足发动机推力控制要求。

The technical difficulty is accurately controlling the low-pressure rotor speed through adjusting nozzle throat area.

技术难点在于通过调节喷管喉道面积,精确控制发动机低压转子转速.

Based on the interior trajectory calculation model of the launch system, the parameters of missile movement and interior trajectory performance are numerated and analyzed for the influence of gas generator nozzle throat area on launch power.

根据发射系统内弹道计算模型，针对燃气发生器喷喉面积对导弹发射动力的影响进行导弹运动参数、内弹道性能的计算与分析。
