1.Scramjet is the perfect propulsive device to hypersonic vehicle, and is a hot issue in current hypersonic technology area.

超燃冲压发动机是高超声速飞行器理想的动力装置，是当前高超声速技术领域的研究热点。

2.The Chinese allowed a peek into multiple aspects of their scramjet efforts at the recent American Institute of Aeronautics and Astronautics Joint Propulsion Conference in Cincinnati.

在最近辛辛那提举行的美国航空航天联合推进技术研究所大会上，中国让外界得以一窥其在冲压发动机方面的多个进展。

3.In such a scheme, a payload vehicle (holding, say, a satellite) would piggyback to high altitude aboard the scramjet, which in theory could reach near-orbital speeds.

在这个方案中，一个载物飞行器(比如说搭载着卫星)将(首先)搭载超燃冲压发动机进入相当高度，理论上能够达到近似轨道速度。

4.The longest previous hypersonic scramjet flight test, performed by a NASA X-43 in 2004, was faster, but lasted only about 10 seconds and used less logistically supportable hydrogen fuel.

先前最长的冲压式喷气发动机下极超音速飞行测试，是在2004年由NASA的X-43进行的，速度更快，但只持续了10s。

5.Fuel supply control system is the core of the scramjet control system. Its performance and reliability decide the performance and reliability of the scramjet.

燃油供给系统控制是超燃冲压发动机控制系统的核心，它的性能和可靠性决定了整个超燃冲压发动机系统的优劣和发动机的安全可靠。

6.Scramjet combustor design optimization for a test scramjet model engine is conducted by employing genetic algorithms, and an optimal design much better than original design is obtained.

采用遗传算法对某试验超燃冲压模型发动机的燃烧室构型参数进行了优化设计，所得方案的性能大大优于实际方案。

7.Regenerative cooling technology is one of the key technologies to thermally protect scramjet chamber.

再生冷却技术是超燃冲压发动机燃烧室热防护的关键技术。

8.The internal flow fields in scramjet are very complex, due to the interaction of shock waves, expansion waves, boundary layer and strong reactions.

超燃冲压发动机的内部流场很复杂，存在激波、膨胀波、附面层和剧烈的化学反应等相互作用，给数值模拟带来很大的困难。

9.Here it would reach supersonic speeds and then shift to its scramjet engine. The scramjet scoops up air and mixes it with fuel so it burns as the mixture flows through the engine at supersonic speeds.

这里它将达到超音速然后超高速冲压喷气发动机切换成工作状态，迎面气流进入发动机，与燃料混合，混合物在超音速状态流过引擎。
