Since then, all modern jets and even some turboprops have come with their own APUs.

从那时起，所有现代喷气式机甚至一些涡轮螺旋桨机都配备了自己 APU。

However, APUs aren't all good news.

然而，APU 也不全是好消息。

Indeed, some airports have restricted APU  usage at night to soothe local communities.

事实上，一些机场已限制 APU 在夜，以安抚当地社区。

The APU was filled with water from natural and artificial reservoirs up to 3 meters deep.

APU 充满了来自深达 3 米天然水库和人工水库水。

From cabin lights to  avionics onboard, APUs have become essential for modern jets.

从机舱灯到机载航空电子设备，APU 已成为现代喷气式机必不可少。

This means crews will generally  switch off the APU when taking off and reignite it while cruising for emergency  use.

这意味着机组人员通常会在起时关闭 APU，并在巡航时重新点燃以备紧急。

Unusually, the APU on the 727 was not in  the rear of the aircraft.

不同寻常是，727 上 APU 并不在机。

Did you know about the  presence and role of the APU?

您知道 APU 存在和作吗？

APUs became common in the 1960s, with Boeing  including the first commercial APU for a jetliner in the 727 in 1963.

APU 在 1960 年代变得普遍，波音公司在 1963 年为 727 喷气客机配备了首个商 APU。

The best way to do this is to start  the APU (which is not normally running in flight).

最好方法是启动 APU（它通常不会在行中运行）。

The presence of an APU in the 727 allowed airlines to avoid reliance on ground power at smaller  airports.

APU 在 727 中存在航空公司能够避免在较小机场依赖地面动力。

The APU will power critical functions  like cockpit displays and radios, as well as passenger comforts like air conditioning, heating, lights, and galley equipment.

APU 将为驾驶舱显示器和收音机等关键功能提供动力，以及空调、供暖、灯光和厨房设备等乘客舒适设施。

Especially if we really are a couple of years away from the next generation of consoles, it's very easy to imagine a full eight-core Ryzen CPU set up inside a console APU.

特别是如果我们离下一代游戏机还有几年时，我们不难想象在一台游戏机 APU 中设置一个完整8核 Ryzen CPU。

If you've been grateful for cheaper tickets, longer nonstop flights, and a cool cabin when you  walk onboard, the APU is to thank in many cases.

如果您对更便宜机票、更长直航班和凉爽机舱感到感激，那么在很多情况下， APU 就是感谢。

An APU is a small turbine  engine that, on modern jets, is attached to the rear fuselage of the aircraft to provide power  onboard when the main engines are switched off.

APU 是一种小型涡轮发动机，在现代喷气式机上，它安装在机机身，以便在主发动机关闭时提供机载动力。

By utilizing the APU  bleed air for an engine start, it allows pilots to select the best lift to drag ratio speed to extend  the glide range during engine re-start attempts.

通过利 APU 引气启动发动机，它允许行员选择最佳升阻比速度，以在发动机重新启动尝试期扩大滑翔范围。
