Two pilots recently set a new altitude world record for gliders.
最近，两名飞行员创下了滑翔机高度的世界纪录。
A glider is an aircraft that does not have an engine.
滑翔机是一种无引擎的飞行器。
They are pulled into the air by powered airplanes and then released.
动力飞机将滑翔机拉升到空中后将其释放。
They are designed to ride warm, rising air to gain altitude.
滑翔机的设计旨在通过上升的热气流带动来增加高度。
The Perlan II glider reach an altitude of 15,902 meters on September 3.
9月3日，Perlan II滑翔机达到了15902米的飞行高度。
The two pilots flew their aircraft above mountains in southern Argentina.
两名飞行员驾驶飞行器成功飞越了阿根廷南部的群山。
The pilots beat the earlier world record for gliders by 441 meters.
两名飞行员打破了滑翔机飞行高度441米的世界纪录。
The pilots hope the ability of their plane to reach the edge of outer space will influence young people to follow careers in science and engineering.
飞行员们希望滑翔机能够到达外太空边缘，这将引领年轻一代向科学和工程领域进行探索。
The glider was pulled into the air by a small plane.
Perlan II滑翔机由一架小型飞机拉升至上空。
At about 3,000 meters, the plane released the connecting cable and started looking for strong updrafts of air,called the mountain waves, to take them higher.
待攀升至3000米后，飞机松开绳索并等待上升气流（地形波）来带动滑翔机继续攀升。
According to chief pilot Jim Payne it took eleven flights to reach the altitude record.
首席飞行员吉姆·佩恩（Jim Payne）称，滑翔机攀升11次后才到达如今的高度。
Basically, we take steps of certain amount of altitude and airspeed,gather data, analyze that data
“基本上，我们到达某一高度和空速后会收集数据并对数据进行分析，
and if those data conform to our theory and the model we have for the airplane - then we can safely go on to the next step.
如果数据符合理论以及飞机的模型，那我们就可以安全开展下一步工作。”
A glider flight at high altitude is very difficult. The glider has no engine to fight turbulence they may encounter.
滑翔机很难高空飞行。它没有发动机，无法应对可能遇到的不稳气流。
Also, although the airspeed instrument shows the speed of only 80 to 90 kilometers per hour,the true airspeed can be much higher.
此外，尽管空速仪显示速度仅为每小时80至90公里，但是真正的空速会快得多。
At those high speeds, the wings may flutter to the point of breaking.
在高速飞行时，滑翔机机翼可能会震颤至断裂。
Also, it is very cold said pilot and project manager Morgan Sandercock.
飞行员兼项目负责人摩根·桑德尔柯克（Morgan Sandercock）补充称，飞行时的温度很低。
We have electric socks on the pilots, we literally could not fly without those electric socks, we would get frostbite.
“我们的飞行员会穿电袜子，如果没有电袜子，根本就无法飞行，我们会被冻伤。
And heated vests and we’re looking at upgrading our heating systems for next year because cold is the big issue that we’ve been dealing with this year.
还有加热背心，明年我们会升级加热系统，因为寒冷是我们今年需要解决的一大难题。”
The Perlan II glider is made of special kind of light carbon fiber material. It also has improved mechanical properties.
Perlan II滑翔机由特殊的轻薄碳纤维材料制成。其机械性能也得到改进。
The company Airbus helped build the glider and transport it to Argentina.
空中客车公司制造了这一滑翔机并将其运往阿根廷。
Ken McKenzie, an employee with Airbus, says the company hopes the project will attract young people to science and technology.
空中客车的职员肯恩·麦肯齐（Ken McKenzie）表示，空客希望该项目能吸引年轻人关注科学技术领域。
We want to actually grab the next group of pilots, engineers, mechanics, airport operators, flight attendants,basically kids that are in high school and university right now
“其实，我们希望能够发掘下一代飞行员、工程师、机械师、机场操作员、空乘，他们基本上都是些读高中和大学的青年，
that may not have considered aerospace as a careerand we want to inspire them.
他们没有考虑过将航空列入未来职业规划，我们想鼓励这一群体。”
In the future, the pilots hope to break the world altitude record for level flight of 25,929 meters, set in 1979 by the U.S. spy plane called the SR-71 Blackbird.
未来，飞行员希望能够打破25929米高度的世界纪录，该纪录由美国的侦察机SR-71黑鸟式侦察机在1979年创下的。
The pilots also plan to turn their aircraft into a non-polluting research vehicle for the stratosphere.
飞行员们还计划将飞机改造为在平流层飞行的无污染研究机型。
