There is a range of applied force over which the regression rate remains constant . 施加的力有一個(gè)范圍,在這個(gè)范圍內(nèi)遞減率保持不變。
The plateau domain is defined as a pressure regime in which the regression rate is insensitive of pressure . 平臺區(qū)是定義為這樣一個(gè)壓力區(qū),即其中壓力對速度沒有影響。
Model about regression rate of hybrid rocket motors was studied 研究了固液發(fā)動(dòng)機(jī)固體燃料退移速率預(yù)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 通過對兩臺發(fā)動(dòng)機(jī)試驗(yàn)結(jié)果的分析,找出了試驗(yàn)中氧化劑流量偏高、燃料退移速率和發(fā)動(dòng)機(jī)性能偏低的原因,并提出了具體的改進(jìn)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 研究結(jié)果表明:壓強(qiáng)、推力和燃料退移速率隨發(fā)動(dòng)機(jī)工作時(shí)間增加而降低,氧化劑和燃料的配比升高;節(jié)流時(shí),發(fā)動(dòng)機(jī)比沖降低。
