The Air-cushioned Vehicle that Travels Clear Out of Sea and Land
The air-cushioned vehicle is not an airplane, since it does not have wings.It is neither a ship nor an automobile, since it travels clear of sea and land.It has a conventional gasoline engine, but no wheels.How does it travel？What keeps it in the air？
Under the air car is an air chamber with a large propeller parallel to the ground.The gasoline engine supplies power that causes the propeller to whirl.This fills the chamber with air.Some of the air is forced toward the ground through tiny holes around the edges of the car.
These air jets create a wall that keeps the air from escaping from the chamber.As more and more air crowds into the chamber, the molecules of air become compressed.Their pressure becomes so strong that it lifts the car off the ground.
Once the car is floating, the driver releases some of the compressed air.This makes the car speed forward.
脫離海面和陸地行駛的氣墊船
氣墊船不是飛機，因為它沒有雙翼。它不是輪船，也不是汽車，因為它脫離海面和陸地行駛。氣墊船裝有常規(guī)的汽油發(fā)動機，但沒有輪子。它是怎樣行駛的呢？是什么使它懸在空中的呢？
氣墊船下面是一個空氣箱，里面裝有一個與地面平行的大螺旋槳。汽油發(fā)動機供能后，螺旋槳便旋轉(zhuǎn)起來，這就使氣箱內(nèi)充滿了空氣。部分空氣通過氣墊船邊緣的小孔被壓向地面。
這些噴射出的氣流形成一道屏障，阻止空氣從氣箱逸出。由于越來越多的空氣聚集在氣箱內(nèi)，空氣分子受到壓縮。正是這些空氣分子的強大壓力使汽墊船脫離地面。
當(dāng)汽墊船浮動時，司機釋放出一部分壓縮空氣，使汽墊船高速向前飛行。
