Combining a rocket, a jet and a racing-car engine into one vehicle is engineering of an extreme sort, but record-breaking often demands that new problems be solved.
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。
The idea that solar energy will have to wait for a breakthrough to reach grid parity is "crap," he says. He adds: "We're not talking about rocket science. We're talking basic engineering.
他接着说：“太阳能要达到市电同价不得不等待一个突破，这是一个赌注”，“我们在谈论的不是有关火箭的科学，我们在探讨的是基础工程。”
It was shown that the detail construction of turbulence in rocket can be predicted by LES, and the time-averaged method also can give the result with satisfiable engineering precision.
结果表明：大涡模拟技术可以得到发动机内湍流流场中详细拟序结构，时均湍流模拟对于火箭发动机内流场时均量的模拟仍有较好的工程精度。
