High Performance Hovercraft With Power Turning


Abstract: Hovercraft is a non wheeled vehicle which hovers over or moves across all types of surfaces including grass, mud, muskeg, sand, quicksand, water and ice very easily using high powered fans (propellers) and aerodynamicdesign. It is also called as Air Cushion (AC) Vehicle. Main Objective of this project work to be carried out is to design a Hovercraft using Lift System and Spy Camera which can be controlled by Remote and uses two high rpm BLDC motors interfaced with a Micro-Controller to achieve desired functionality. Moreover the purpose of presenting this paper is to implement new ideas and concepts to make design safer,cost effective, light in weight, more aerodynamically and importantly more environmental friendly. The motor which is below the hovercraft rotates at a very high RPM that allows it to generate a force enough to make it hover on the surface, whereas motor mounted behind it, help to push the hovercraft in forward direction. The movement of hovercraft is controlled through remote which send command to the micro-controller which generates pulse signals for the motor to be operated. A camera is also fitted on its top which records the surrounding activities and displays it on the screen.Hovercraft works on the principle of lift and propulsion. The basic mechanism of a hovercraft is very simple: there are two BLDC (Brushless DC) motors that power both fans (propeller). The motor at centre have fan i.e. which is pointed downward is used to lift the craft. When this motor is operated, it creates the cushion of air in skirt and lifts the craft slightly above the ground. Once the craft is hovered or lifted or a cushion is formed, thrust must be created to move the hovercraft in a forward direction. So the second motoris fixed at the back side if the craft. When this motor operated, it makes the craft to move in forward direction.The movement of hovercraft is controlled by using Remote Control which sends command to the controller fixed on hovercraft. Micro-controller receives the command and sends the pulse signal to the brushless motors to run. When motor is started the hovercraft is lifted slightly above the ground due to the formation of air cushion. There is also fitted a camera which capture all the recordings around the craft where the craft move. These recordings are then displayed on the screen.Aerodynamics is defined as the branch of fluid physics that studies the forces exerted by air or other gases in motion. Hovercraft works on aerodynamic principal as it float on cushion ofair created by the air developed by propellers. This air formed beneath the hovercraft help to reduce the friction between the hovercraft and ground. This reduction on friction due to air cushion increases the speed as well as efficiency of hovercraft. For maximum efficiency, the aim is usually to design the shape of an object to produce a streamlined flow, with a minimum of turbulence in the moving air
