依靠发动机向后喷射工作物质产生的反作用力而推进的飞行器,称为火箭。它的特点是自身携带燃料和氧化剂,既可在大气中飞行,又可在没有大气的外层空间飞行。现代火箭是远距离快速投送工具,可用于发射人造卫星、载人飞船、航天站以及助推其他飞行器。火箭用于投掷弹头,便称为火箭武器,其中可制导的又称为导弹。 Aircraft propelled by reaction forces generated by the engine’s rearward jet of work material are called rockets. It is characterized by its own fuel and oxidant, can fly in the atmosphere, but also in the outer space without the atmosphere flight. The modern rocket is a long-range rapid delivery tool that can be used to launch satellites, manned spacecraft, space stations and other aircraft. Rocket used to throw warheads, they are called rocket weapons, which can be guided also known as missiles.
