I used nose attitude instead of modulating engine thrust to control airspeed during the climb to 15 , 000 feet 在爬升至15 , 000英尺高度的過程中我用機(jī)首的高度代替發(fā)動(dòng)機(jī)節(jié)流閥來控制飛行速度。
It indicates that thermal throat can substitute geometry throat , so structure integration can be achieved in ejectrojet mode . in addition , it showed that thermal throat will increase engine thrust and decrease specific impulse 另外還得到熱力喉道取代幾何喉道后對(duì)發(fā)動(dòng)機(jī)性能的影響,它可以提高發(fā)動(dòng)機(jī)的推力,卻要降低比沖。
