Presentation On Hovercraft Presented By: Guided Udit Ahuja By:Dr Raayush Dhar Subrata Das Tejveer Singh Sachin Dwivedi

Objectives  Build a working, autonomous hovercraft  Complete the course, even if it takes all the allotted time.  Maximize maneuverability of the hovercraft  Make the lightest and most cost efficient hovercraft possible

Basic components of hovercraft  1. Propellers 2. Air 3. Fan 4. Flexible skirt

Equipment List  2 sheets of core board  5 motors  1 switch  1 battery connecter  1 rudder kit  1 big motor  2 batteries  Radio controller and receiver

Skirt and Body  Assignments:  Design and build a durable and lightweight body and skirt  Find the best placement of parts  Use cost efficient materials  Create a leak free seal to the body of hovercraft

Design Process  Decided to first build a prototype to test ideas on so that we don’t have to worry about perfect dimensions and appearance.  Final version is the one where we carefully measured everything and used color coordinated materials.

Lift and Propulsion  Assignments:  Choose the adequate placement of fans  Find powerful yet efficient fans to propel the hovercraft  Find reversible fans  Determine the best methods to power the fans

Structural Base

Skirt Design  We considered an open, full, and tubular design.  The tubular design was too complicated.  The open design didn’t hold enough air in.  We finally decided on a full skirt with holes to let some of the air out because it is simple and reliable.

Method of Sealing the Skirt

Number of Fans  Originally, we considered having 2 fans. 1 down for lift and 1 backwards for thrust.  Then, we thought about using each fan for both thrust and lift by dividing the air stream.  We finally decided to use a larger motor for thrust and a fan for lift.

Our Wish List  RCX  Lexan (for the base material)  Rubber (car inner tube or thin material for skirt)  Battery Holder (for 8 double AA’s)  2 axial fans  1 lift fan  Relays  Zener Diodes (6)  LED’s  Wire
