Presentation On Hovercraft

Guided By:Dr Subrata Das

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
