固体燃料火箭发动机的构造更简单、分量更轻，而且相对更安全。 在固体燃料火箭发动机里，燃料和氧化剂被预先混合成稳定的液态推进剂，然后被塞满火箭发动机的燃料箱里。
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.
铝已经成为了许多火箭燃料小却关键的组成部分，包括航天飞机固体燃料推进火箭和国家宇航局下一代的Ares火箭。
Aluminum already represents a small but critical part of many rocket fuels, including the propellants for the space shuttle's solid booster rockets and NASA's next generation Ares rockets.
该火箭的第一级是发射航天飞机用的固体燃料火箭的马力加强版；顶端一级是同样增强了马力的用在土星火箭上的J2巨型发动机。
Its first stage is a souped-up version of one of the shuttle's solid-fuel rockets; its top stage is a similarly muscled-up model of the Saturn's massive J2 engines.
6秒之后，航天飞机的双固体燃料火箭推进器点火，固定航天器的爆炸螺栓切断，整个航天飞机一飞冲天。
After those six seconds, a shuttle? S twin solid rocket boosters ignite, explosive bolts holding the spacecraft down are severed and the entire stack soars spaceward.
在使用固体燃料的火箭中，燃料混合物的反应比较缓慢而稳定，而不是爆发性的。
In a solid-fuel rocket the reaction of fuel mixture is relatively slow and steady rather than explosive.
它是一种二级、重量15吨固体燃料推进火箭可以改为携带一枚重量半吨的侵彻、高爆弹头，连同专用制导系统一起(一套雷达和图像识别系统)。
It's a two stage, 15 ton, solid fuel rocket that could instead carry a half ton penetrating, high-explosive warhead, along with the special guidance system (a radar and image recognition system).
由于氧化剂和燃料的燃烧方式不同，固液火箭发动机工作过程和液体火箭发动机及固体火箭发动机有很大的区别。
Owing to the dissimilar combustion mode, their working process is different form that of solid rocket motors and the liquid rocket engines.
