A hovercraft (pl.: hovercraft [1]), also known as an air-cushion vehicle or ACV, [2] is an amphibious craft capable of travelling over land, water, mud, ice, and various other surfaces. Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference ...
Simply pumping air between a hull and the ground wasted a lot of energy in terms of leakage of air around the edges of the hull. Cockerell discovered that by means of generating a wall (curtain) of high-speed downward-directed air around the edges of a hull, that less air leaked out from the sides (due to the momentum of the high-speed air ...
A hovercraft, or air-cushion vehicle, is a vehicle or craft that can be supported by a cushion of air ejected downwards against a surface close below it, and can in principle travel over any relatively smooth surface, such as gently sloping land, water, or marshland, while having no substantial contact with it. [1]
Cockerell's theory was that instead of just pumping air under the craft, as Thornycroft had, if the air were to be instead channelled to form a narrow jet around the perimeter of the craft, the moving air would form a momentum curtain, a wall of moving air that would limit the amount of air that would leak out. This meant that the same cushion ...
The Zubr class, Soviet designation Project 1232.2, (NATO reporting name "Pomornik") is a class of Soviet-designed air-cushioned landing craft (LCAC). The name "Zubr" is Russian for the European bison. [5] This class of military hovercraft is, as of 2023 the world's largest hovercraft, [6] with a standard full load displacement of 555 tons.
Harrison said, for the hovercraft to be legal to use in Las Vegas' Lake Mead, it would need to have an updated 2006 EPA-compliant sticker on its motor.
