Piloting a Hovercraft

Piloting a Hovercraft
Driving a hovercraft requires many different skills and techniques. Since it has nothing in contact with the surface it has a greater turning radius and a greater stopping distance. Directional control is maintained with a rudder. There is a slight time delay between the moving of a control and the reaction of the vehicle. All motion is provided by thrust. The hovercraft can be stopped by applying reverse thrust, reducing power, making a 180 degree turn and applying thrust, or any combination of these.

First time drivers should practice in a empty lake or field. A hovercraft will travel faster over land, ice, or snow than over water. On water the air pressure that supports the craft presses the surface of the water down. As the craft is pushed forward a wave is created in front. A hovercraft must have sufficient propulsion to push itself over the wave at which point it planes off. After exceeding planing speed the hovercraft will require very little power to keep going.

At speeds greater than 4 times the planing speed (30 to 40 mph) other drag types take effect. Many kinds of drag exist on a hovercraft. Aerodynamic drag depends on the size, shape, and frontal area of the craft. Momentum drag due to lift systems (usually located in the front of the craft) depends on the amount of air you are supplying to lift the craft. In addition to these forms of drag over water you have wave impact drag, water spray drag, and drag by the skirt occasionally contacting the water.

As a result, you see why it would be easier for a hovercraft to go faster with a tail wind rather than a head wind, or smooth water as opposed to rough water.

Why a Hovercraft?
A well-designed hovercraft is superior to a boat because it has less drag and requires less horsepower to operate. A hovercraft is 100% more fuel-efficient than a boat with similar capacity or size. Rising fuel prices and shortages will make the hovercraft a desirable form of transportation in the future. It is conceivable that someday all watercraft will use the hovercraft principal due to its many advantages.

Hovercraft ride much smoother than boats because they travel over the surface of the water, not through it. It travels over water with no concern for depth or hidden obstacles. They will go against the current of a river with no speed reduction. The hovercraft also works well in rapids and white water, making it an excellent rescue vehicle.

Safety around swimmers and water skiers is far superior to a boat since there is nothing in or on the water. The hovercraft will pass safely over a swimmer or skier. This technique has proven useful when returning the line to a fallen skier.

A hovercraft will eliminate the need to climb in and out at crowded docks or piers. No more tying up every time you dock. Simply drive up onto land, shut off the engine and step out. Your hovercraft will launch from almost anywhere and does not require a special launching ramp like a boat.

Now you will be able to enjoy numerous year-round activities while investing in only one craft. Use it as a boat in the summer to go water skiing, fishing, or camping. In the winter the hovercraft is even more useful. It will travel over soft or heavy snow. You will never have to worry about the thickness of the ice you're traveling over. It makes no difference to the hovercraft.

这应该主要叫做地效飞行器,结合了气垫船的设计。有意思!
自制超轻型飞机,轻型飞机,Mini-max,航空,飞行

恩是地效应器

做的最好的是俄罗斯,里海怪兽那都是前苏联的事了。就没见过国内的在航空上能拿的出手的,除了导弹哈。
