涡轮泵

A separate disc was utilized in the J-2 LH2 turbopump for a double-acting balance piston.

一个单独的光盘是利用在J型2 lh2涡轮泵为双作用平衡活塞。

In this paper an order tracking technique and double threshold trigger technique are developed to ensure the synchronous data acquisition and to eliminate the disturbance and noise in rocket speed signal.

由此可保证各倍频分量幅值的精度，减少频率泄漏，同时保证了各帧数据具有相同的相位基准。同步、同相基整周期采集需由转速信号触发采集来实现。一般情况下，涡轮泵转子上的测速盘为多齿盘。

This has brought a lot of difficulties for the design of the turbopump.

这给涡轮泵的设计带来了很大的困难。

Such as the working demands on turbopump technology.

如工作的要求，涡轮泵技术。

The turbopump configuration is highly dependent on the engine cycle and the engine requirements for flow and pressure.

涡轮泵的配置是高度依赖于引擎周期和发动机的要求，流量和压力。

The type of engine cycle selected also influences the turbopump requirements and configuration.

该型发动机的周期选定也影响了涡轮泵的要求和配置。

Turbopump is an important part in liquid rocket engine.

涡轮泵是液体火箭发动机的重要组成部份。

The turbopump is optimized for performance and weight within the minimum possible envelope size to facilitate engine packaging.

涡轮泵是优化性能和重量与最低可能的信封尺寸，以方便发动机的包装。

The engine throttling requirements define the range of flow and discharge pressure that the turbopump must deliver with stable operation.

发动机节流的要求，界定范围的流动和排放的压力，涡轮泵必须提供与稳定运行。

Static and dynamic seals are employed to preclude mixing of propellants within the turbopump which would result in burning and catastrophic failure.

静态和动态密封是受雇于排除混合推进剂内部的涡轮泵这将导致燃烧和灾难性的失败。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
