Airboat Airboat Presentation Transcript

  • AIR-BOAT
  •    An airboat, also known as a fanboat is a flatbottomed 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
  • 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.
