pdf on advantages and disadvantages of hovercraft

Hovercraft operate on a cushion of air and during their earlier years were considered to fly above the surface below. They generate a volume of lift air, maintained by a flexible skirt at a higher pressure than the atmospheric pressure above. Their weight is therefore balanced by the lift that is generated.

Our hovercraft use commercially available technology, are diesel powered, and use aluminium as the primary hull structure to make them easy to maintain and repair in the field.

HOVERCRAFT CAN USE ON ANY SURFACE.

i-VTEC system is more sophisticated than earlier variable-valve-timing systems, which could only change the time both valves are open during the intake/exhaust overlap period on the transition between the exhaust and induction strokes. By contrast, the i-VTEC setup can alter both camshaft duration and valve lift. i-VTEC Technology gives us the best in vehicle performance. Fuel economy is increased, emissions are reduced, derivability is enhanced and power is improved.

HOVERCRAFT
1. INRODUCTION
Vehicles designed to travel close to but above ground or water. These vehicles are supported in various ways. Some of them have a specially designed wing that will lift them just off the surface over which they travel when they have reached a sufficient horizontal speed (the ground effect). Hovercrafts are usually supported by fans that force air down under the vehicle to create lift, Air propellers, water propellers, or water jets usually provide forward propulsion. Air-cushion vehicles can att ....etc

HOVERCRAFT



INTRODUCTION

A hovercraft is a vehicle capable of traveling over most surfaces on a cushion of air trapped under the body for lift. Air propellers, water propellers, or water jets usually provide forward propulsion. Air-cushion vehicles can attain higher speeds than can either ships or most land vehicles due to lower frictional forces and use much less power than helicopters of the same weight. Figure 1 below illustrates the operational principles and basic components ....etc

A Hovercraft is a vehicle that flies like a plane but can float like a boat, can drive like a car but will traverse ditches and gullies as it is a flat terrain. A Hovercraft also sometimes called an air cushion vehicle because it can hover over or move across land or water surfaces while being held off from the surfaces by a cushion of air. A Hovercraft can travel over all types of surfaces including grass, mud, muskeg, sand, quicksand, water and ice .Hovercraft prefer gentle terrain although they are capable of climbing slopes up to 20%, depe ....etc

Abstract :
A hovercraft or air-cushion vehicle (ACV) is a craft, designed to travel over any smooth surface supported by a cushion of slow moving, high-pressure air, ejected downwards against the surface below, and contained within a skirt. Because they are supported by a cushion of air, hovercraft are unique among all forms of ground transportation in their ability to travel equally well over land, ice, and water.
The main parts of a hovercraft are:
Skirt Hull
Lift Fan Thurst Fan
Basic Design:
The lifting motion is controlle ....etc
