There is a range of applied force over which the regression rate remains constant . 施加的力有一个范围,在这个范围内递减率保持不变。
The plateau domain is defined as a pressure regime in which the regression rate is insensitive of pressure . 平台区是定义为这样一个压力区,即其中压力对速度没有影响。
Model about regression rate of hybrid rocket motors was studied 研究了固液发动机固体燃料退移速率预示模型。
The reasons for higher oxidizer flow rate , lower fuel regression rate and lower motor performance in both hot firings are discussed . several necessary improvements for the test system are suggested . 6 通过对两台发动机试验结果的分析,找出了试验中氧化剂流量偏高、燃料退移速率和发动机性能偏低的原因,并提出了具体的改进措施。
The results of research indicate that the pressure , the thrust and the fuel regression rate of the motor decrease while the o / f ratio increasing with the burning time lasting . the special impulse reduces when throttling 研究结果表明:压强、推力和燃料退移速率随发动机工作时间增加而降低,氧化剂和燃料的配比升高;节流时,发动机比冲降低。
