The 27-year-old will undertake the first full test firing of a hybrid rocket whichhe has designed to help a British team set a new land-speed record by driving at 1,000mph.

3、0 jetengine from a Typhoon fighter aircraft and a Cosworth Formula 1 racing engine if BloodhoundSSC is to become the fastest thing on wheels. 今年夏天丹尼尔?兆伯要做的事，相当于点燃导火索然后跑开。这个27岁的小伙子将进行一枚混合式火箭发动机的第一次全程试射，他设计这枚火箭发动机用于关心英国车队缔造一个以时速1000英里驱动的地面速度记录。然而，假如侦探犬号超音速车要想成为靠轮子跑得最快的东西，那么兆伯的火箭发动机还将需要一个强大的台风战斗机EJ200喷
4、气发动机和一个考斯沃斯一级方程式赛车发动机的帮助。 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 bes
5、witched 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，但是破纪录常常需要解决许多新问题。兆伯的工作是建筑一枚可以在汽车里平安使用的火箭发动机，但是它也要可掌握并且在消失紧急状况时可以快速关掉。 A rocket works by burning fuel with an oxidiser,which provides a source of oxygen for combustion.The hot exhaust gases are then blasted throug
6、h 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，
7、氧化剂供应燃烧需要的氧气，排放的热气于是通过一个喷嘴喷出以产生推力。使用液态推动前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简单地关掉，但是它们往往很简单，而且它们的推动前进剂操作困难且有危急性，比如液态氢和液态氧。 The land-speed record 地面速度记录 How to build a 1,000mph car 怎样建筑时速1000英里的汽车 Hybrid rocketry will be used to drive faster than everbefore 混合火箭技术将用于更快地驱动车辆 May 5th 20xx | from the print edi

10、车队缔造一个以时速1000英里驱动的地面速度记录。然而，假如侦探犬号超音速车要想成为靠轮子跑得最快的东西，那么兆伯的火箭发动机还将需要一个强大的台风战斗机EJ200喷气发动机和一个考斯沃斯一级方程式赛车发动机的帮助。 Solid-fuel rockets, in which the fuel and oxidiser are pre-mixed into a stable, solid propellantand then packed inside the case of the rocket, are simpler, lighter and relatively safer. But o
11、ncea solid-fuel rocket is ignited, it is off like a firework and keeps going until all the fuel is burnedup. About the only way to stop it is to blow it apart. In a car, that would not do. 固体燃料火箭发动机的构造更简洁、重量更轻，而且相对更平安。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动前进剂，然后被塞满火箭发动机的燃料箱里。但是一旦固体燃料火箭发动机被点燃，它将象二踢脚一样放射出去并始
12、终跑，直到全部燃料烧完为止。是它停止的几乎唯一的方法，就是将它甩掉。而在汽车上，这做不到。 Rubber power 橡胶动力 The hybrid design which Mr Jubb has come up with uses a solid fuel called hydroxyl-terminatedpolybutadiene, a form of synthetic rubber used to make things like aircraft tyres. It iscontained within the case of the rocket, into which is
13、pumped a liquid oxidiser called high-testperoxide , a concentrated form of hydrogen peroxide which is relatively safe to handle.When the HTP comes into contact with a catalyst contained within the rocket, it turns intosteam and oxygen. And it does so at a high enough temperature to ignite the solid fuel. Thisprovides the added advantage of not having to build an ignition system into the rocket. 5 / 5
