space rocket engine

Based on a space liquid rocket engine system, the static and dynamic characteristic of pressure-fed Liquid Propellant Rocket Engine was studied, furthermore, analyses of the static and dynamic characteristic were also carried out for the valve of the system.

本文以挤压式液体火箭发动机为研究对象，以工程研制为背景，对小型的空间液体火箭发动机系统进行静态特性及动态特性的研究，并且对系统中的电磁阀的静、动态特性进行了分析。

Materials and application methods of solid lubrication applied to bearings in jet aeroplane engine, liquid propellant rocket, space vehicle, driving mechanism of neuclear reactor, and high temperature bearing are presented.

本文介绍了喷气式飞机发动机轴承、高温轴承、液体燃料火箭轴承、宇宙飞行器轴承及原子能反应堆驱动机构轴承用的固体润滑材料与润滑法。

Then, soon after the 27-engine rocket roared into space, he tweeted near-surreal footage of one of his red Tesla Roadster cars with a dummy astronaut strapped onboard orbiting the Earth.

然后，在这枚搭载27台引擎的火箭轰鸣着进入太空后不久，他在Twitter上发布了一段超现实的画面：他的一辆红色特斯拉跑车Roadster绕着地球飞行，车里面坐着一具身穿宇航服的假人。

Based on the condition that the performance test data of liquid rocket engine is subject to normal distribution with constant standard deviation, the Bayes method is used to analyze the environment factor of ground and space performance test.

基于液体火箭发动机性能试验数据服从正态分布的条件，假定天地试验环境下分布的标准差不变，运用Bayes方法对正态分布天地试验条件下的环境因子进行分析。
