查询词典 scramjets

China already has such segmented solid rocket motor and ramjet capabilities today,but scramjets are a much greater challenge.

中国已经掌握了这种分离式火箭助推器和冲压发动机技术，但液态氧是一个更大的挑战。

Combustion control and performance evaluation for scramjets need effective measurement information, therefore it is important to choose the optimal location and number of sensors. This problem is a combinatorial optimization problem which is difficult to solve.

超燃冲压发动机的燃烧控制和性能评估需要有效的燃烧室测量信息，而如何确定传感器的最佳位置和数量是非常重要的，要求选择最小的传感器数目和最佳的测量位置来较准确的描述燃烧室工作特性，这是一个组合优化问题，直接求解比较复杂。

China already has such segmented solid rocket motor and ramjet capabilities today, but scramjets are a much greater challenge.

中国已经拥有这种分离式火箭助推器和冲压发动机技术，但超音速燃烧冲压发动机是一个更大的挑战。

With fuels of hydrogen and hydrogen-ethylene mixture in the wind tunnel heater, experiments to study hydrogen combustion in scramjets were carried out.

本文选择氢气及氢气－乙烯混合气体两种燃料在风洞加热器中加热空气来开展氢气燃烧的研究实验。

All are based on so-called scramjets, which mix fuel with air and ignite the mixture as it flows through the engine at supersonic speeds.

这些都依赖于被叫做超音速冲压喷射引擎（即超音速燃烧冲压喷射引擎），当燃料与空气混合后再点燃就能以超音速的速度飞出引擎。

Although a dual-mode scramjets configuration is simple and mainly consists of inlet, combustor and wake nozzle, its working process is complicated, especially in the combustor, involving a lot of subjects, including hypersonic aerodynamics, combustion chemistry, etc.

虽然双模态冲压发动机结构简单，主要由进气道、燃烧室和尾喷管三部分组成，但其工作过程却十分复杂，尤以超音速燃烧室的工作规律最为复杂，设计难度最大。
