AIR-BOAT

An airboat, also known as a fanboat is a flat-bottomed vessel propelled in a forward direction by an aircraft-type propeller and powered by a motor.

The first airboat, called the Ugly Duckling, was built in 1905 in Nova Scotia, Canada.

The airboat travel over places where normal boats cannot go, such as shallow rocky water, swamps, ice and sometimes-even grass.

ACTION PLAN: To design and construct an airboat by using appropriate

materials and accordingly utilize a motor ,battery and servo motor to provide maximum efficiency. efficiency.

utilize a motor ,battery and servo motor to provide maximum

efficiency.

BALSA WOOD : Light weight with a low density of about 160kg/m3 and has a very high stiffness. It is easily workable.

LITHIUM ION BATTERY: It is a rechargeable battery in which lithium ions move from negative to positive electrodes during discharge and back when charging. This is much lighter than other energy equivalent batteries. Very light weight and wide variety of shape and sizes available.

BRUSHLESS DC MOTOR : These are also know as electronically commutated motor. These are

synchronous motors powered by DC electric source via a switching power supply which produces an

AC electric signal to drive the motor . The advantage as

compared to brushed motor is that it is very cheap and

adjustment of speed is better. They can develop high torque with good speed response . In addition they can be easily automated for

remote control.They have good thermal

characteristics and high energy efficiency.

RUDDER: It is used to steer

the air boat by minimizing aero-dynamic drag. It is made of flat plate section of balsa wood . It is carved and sanded to a smooth section.

PROPELLER: Type of fan

that transmits power by converting rotational motion into thrust.

SERVO MOTOR: A servo

motor is a rotating actuator that allows for precise control of angular position. It consists of a motor coupled to a sensor for position feedback.

RADIO CONTROLLER: It

uses radio signals to remotely control a device. It is hand held radio transmitter for the control of the device.

ELECTRONIC SPEED

CONTROLLER: It is an

electronic circuit with the purpose to vary the electric motor speed, its direction and for dynamic break. It is often used on electrically powered radio controlled models. It provides an electronically generated three phase electric power for brushless motors.

MANEUVER OVER SWAMPY AREAS WHERE UNDER WATER PROPELLER CAN GET STUCK.

AMPHIBIOUS APPLICATION(USED IN LAND AS WELL AS WATER). HENCE MAKES

IT VERSATILE.
