人們已經(jīng)用過(guò)各種類(lèi)型的機(jī)械控制面來(lái)偏轉(zhuǎn)固體推進(jìn)劑火箭的排氣流。
Solid-fuel rockets, in which the fuel and oxidiser are pre-mixed into a stable, solid propellant and then packed inside the case of the rocket, are simpler, lighter and relatively safer.
固體燃料火箭發(fā)動(dòng)機(jī)的構(gòu)造更簡(jiǎn)單、分量更輕，而且相對(duì)更安全。在固體燃料火箭發(fā)動(dòng)機(jī)里，燃料和氧化劑被預(yù)先混合成穩(wěn)定的液態(tài)推進(jìn)劑，然后被塞滿火箭發(fā)動(dòng)機(jī)的燃料箱里。
