Hovercraft Project/seminar Report PDF And PPT Download For Mechanical Engineers
Introduction To Hovercraft : A Hovercraft is a vehicle that,
Flies like a plane but
Float like a boat
Drive like a car
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 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%, depending upon surface characteristics. Modern Hovercrafts are used for many applications where people and equipment need to travel at speed over water but be able load and unload on land. For example they are used as passenger or freight carriers, as recreational machines and even use as warships. Hovercrafts are very exciting to fly and feeling of effortlessly traveling from land to water and back again is unique.
Examples Of Hovercraft Plans
Hovercraft principle:
The principle of working of a Hovercraft is to lift the craft by a cushion of air to propel it using propellers. The idea of supporting the vehicle on a cushion of air developed from the idea to increase the speed of boat by feeding air beneath them. The air beneath the hull would lubricate the surface and reduce the water drag on boat and so increasing its speed through water. The air sucked in through a port by large lifting fans which are fitted to the primary structure of the craft. They are powered by gas turbine or diesel engine. The air is pushed to the under side of the craft. On the way apportion of air from the lift fan is used to inflate the skirt and rest is ducted down under the craft to fill area enclosed by the skirt.
At the point when the pressure equals the weight of the craft, the craft lifts up and air is escaped around the edges of the skirt. So a constant feed of air is needed to lift the craft and compensate for the losses. Thus craft is lifted up. After the propulsion is provided by the propellers mounted on the Hovercraft. The airs from the propellers are passed over rudders, which are used to steer the craft similar to an aircraft. Hovercraft is thus propelled and controlled and its powerful engine makes it to fly.
Working Principle Of Hovercraft Mechanical Project
MAIN PARTS
Lower hull- It is the basic structure on which the Hovercraft floats when the engine is stopped while moving over water. It supports the whole weight of the craft.
Skirts- They are air bags inflated by air are fitted around the perimeter of the craft hold air under the craft and thus upon a cushion of air. It enables to obtain greater Hover height. The material used is rib stop nylon or Terylene.
Lift fan-It is fitted to the primary structure of the Hovercraft. The air is pumped under the craft between the skirt space to produce a cushion of air.
Propeller-It is used to obtain the forward motion of the craft. It is fitted to the top of the craft and is powered by a powerful gas turbine or diesel engine.
Rudders-They are similar to that used in an aircraft. Rudders are moved by hydraulic systems. By moving the rudders we can change the direction of the craft.
Application of Hovercraft
• It will travel against a current of river with no reduction of speed
• A Hovercraft travel over the surface of water without concern for depth or hidden obstacles
• It can travel with great speed of up to 60 knots
• Hovercraft are unaffected by small waves and offer a comfortable smooth ride
• It is safe around swimmers as there are no propellers in water
• Many Hovercraft have sufficient hover height, ranging from 8 in to 18 in to pass right over a person in water
• The air cushion enables Hovercraft to operate over environmentally sensitive areas such as mudflats without disturbing the surface
• The lack of wake on water minimizes the potential for bank erosion
• It can load and unload peoples and equipments on land
• Unlike many boats, engine exhaust fumes are not directed into water and poisonous antifouling compounds are not required on Hovercraft
