CARL AZUZ: It's one thing to design an alternatively fueled aircraft but a plane with no moving parts, now that's electro aerodynamic propulsion for ya.

设计一种替代燃料的飞机是一回事，但是设计一有活动部件的飞机，这就是你的电子空气动力学推进器。

These continuous thrusters succeeded. The pulse thrusters never have.

这种方式的推进器成功了。脉冲推进器从未有过。

But the spacecraft suffered helium leaks and thruster outages.

但是飞船遭遇了氦泄漏和推进器故障。

Our reloading collecting trucks are what's called a pusher packer.

我们的装卸卡车叫做推进器打包机。

It will fly with the help of two sets of four propellers.

蜻蜓号将在2套推进器的帮助下飞行，每套包含4个推进器。

It might even alter its trajectory with an airfoil or mini compressed-gas thruster.

它甚至可以通过翼面或小型压缩气体推进器改变自身道。

Investigations have centered on helium leaks and thruster problems with Starliner.

调查主要集中在 “星际客机” 的氦气泄漏和推进器问题上。

He also suggested the three play a role as thruster in global development.

他还建议三方在全球发展中发挥“推进器”的作用。

Whoa, okay. Satellites have detected ion thruster activity, guys.

卫星已经侦测到离子推进器活动了 各位。

Martinez, what if we point our thrusters in the same direction?

马丁内兹，要是我们把推进器朝同一方向推进呢？

Should we use the thrusters to slow?

需要用推进器来减速吗？

But all these concepts are massively expensive, require safety certification standards for road and air, need dual controls, involve complex folding wings and propellers, and have to be flown from air-strips.

但是所有这些概念都成本高昂，要求路面与空中的安全准，需要双重控制，涉及复杂的折叠机翼和推进器，而且必须从飞机跑道起飞。

We're moving, moving to actually is if we drive current in the opposite direction in the tether and if we could force the current to go the other way it becomes a propulsive device, so a propellantless spacecraft.

我们在移动，实际上是如果我们把系链上的电流往相反的方向牵引，如果我们能迫使电流往相反的方向流动，它就变成了一个推进装置，就是一个无推进器的航天器。

Its ion thrusters put out less force than it takes to push a single key on a keyboard, but it accelerated to over 11 km per second by firing that tiny engine for nearly six years.

它的离子推进器产生的力比按下键盘上的一个键要小，但是通过点燃这个微型发动机将近六年，它加速到每秒 11 公里以上。

It was Starliner's first time carrying astronauts to the ISS but technical issues with thrusters made NASA reconsider the ride home, opting instead to return the crew on a SpaceX spacecraft that's scheduled for an upcoming mission.

这是星际客机首次搭载宇航员前往国际空间站，但推进器的技术问题让美国国家航空航天局重新考虑了返程，选择让宇航员乘坐于即将执行任务的太空探索技术公司的航天器返回。

Nearly three months later, the spacecraft experienced thruster issues when delivering two NASA astronauts, Butch Wilmore and Suni Williams, to the space station in June.It returned to Earth without them on board.

将近三个月后，推进器出现了问题，这发生在六月份飞船向空间站运送两名美国宇航局宇航员布奇·威尔默和苏尼·威廉姆斯的过程中。他们并未跟随飞船一起返回地球。

NASA has been working with Boeing on solutions to the helium leaks in the spacecraft's thruster and now has a plan to get them home in the safest way possible.

NASA 一直在与波音公司合力解决飞船推进器氦气泄漏的问题，现在已经有了一个尽可能安全地送他们回家的计划。

On their way back across the Channel, Bernard insisted on stopping his propeller and hovering on his helicopter screws within a hundred feet of the waves.

在他们俩回来路过英吉利海峡的时候，伯纳坚持要关掉推进器，靠螺旋桨悬浮在海浪上空一百英尺的地方。

To avoid a fiery end, humankind decides to propel our home planet to another galaxy, precisely 4.2 light years away, using thousands of giant rocket thrusters.

为了避免激烈的结局，人类决使用数千个巨大的火箭推进器，将我们的母星推进到另一个星系，精确到 4.2 光年之外。

After Williams and Wilmore arrived at the orbiting outpost about nine months ago, staff found a helium leak and thruster problems on the Starliner vehicle.

威廉姆斯和威尔莫尔大约九个月前抵达道站后，工作人员发现“星际客机” 上存在氦气泄漏和推进器问题。
