听力原文: A little airplane has given new meaning to the term "going hyper".
The Hyper-X recently broke the record for air-breathing jet planes when it traveled at a hypersonic speed of seven times the speed of sound. That's about 5,000 miles per hour. At this speed, you'd get around the world-- flying along the equator-- in less than five hours.
The Hyper-X is an unmanned, experimental aircraft just 12 feet long. It achieves hypersonic speed using a special sort of engine. Actually, engineers have been experimenting with such an engine since the 1960s.
For an engine to bum fuel and produce energy, it needs oxygen. A jet engine, like those on passenger airplanes, gets oxygen from the air. A rocket engine typically goes faster but has to carry its own supply of oxygen. This special engine goes as fast as a rocket, but it doesn't have to carry its own oxygen supply.
Its design allows it to extract oxygen from the air that flows through the engine. And it does so without letting the fast-moving air put out the combustion flames.
A booster rocket carried the Hyper-X to an altitude of about 100,000 feet for its test flight. The aircraft's record-beating flight lasted just 11 seconds.
In the future, engineers predict, airplanes equipped with such engines could transport cargo quickly and cheaply to the edge of space. Hypersonic airliners could carry passengers anywhere in the world in just a few hours.
