Combining a rocket, a jet and a racing-car engine into one vehicle is engineering of an extremesort, but record-breaking often demands that new problems be solved. Mr Jubbs task was tobuild a rocket that could be used safely in a car, but was also controllable and could beswitched off quickly in the event of an emergency.
将火箭发动机、喷气式发动机和赛车发动机整合到一部车里,是一种极不寻常的设计,但是破纪录经常需要解决很多新问题。兆伯的工作是建造一枚可以在汽车里安全使用的火箭发动机,但是它也要可控制并且在出现紧急情况时可以快速关掉。
A rocket works by burning fuel with an oxidiser,which provides a source of oxygen for combustion.The hot exhaust gases are then blasted through anozzle to produce thrust. Rockets using liquidpropellants can be shut down reasonably easily byturning off the pumps delivering the fuel andoxidiser, but they tend to be complex and theirpropellants, such as liquid hydrogen and liquidoxygen, difficult and hazardous to handle.
火箭发动机工作通过燃烧带有氧化剂的燃料,氧化剂提供燃烧需要的氧气,排放的热气于是通过一个喷嘴喷出以产生推力。使用液态推进剂的火箭发动机可以通过关闭输送燃料和氧化剂的泵而被相当容易地关掉,但是它们往往很复杂,而且它们的推进剂操作困难且有危险性,比如液态氢和液态氧。
