• Group 2
• Presented By
• Josh Balsam, Justin Coe, Curtis Sharkey

Overview

• Selected a specific lift fan that will work for
  our design
• Selected propulsion fans as well as power sources
• Will use a bullet shaped body
• We are planning to use a differential sensor to
  keep the hovercraft on track
• Have found sufficient materials for the deck and
  skirt

Team Status

• We have been keeping up with our weekly meetings
• Our subgroups have met and decided on what parts
  and are working on different tasks to contribute
  to the overall design
• We are still uncertain with certain parts of our
  programming though
• For example we are working on how to keep the
  hovercraft on track/maneuver it so that it does
  not completely lose the tape.

Introduction

• We are currently working on different aspects of
  the design so that we can first create a
  hovercraft that floats
• Our most pressing issue is acquiring first a
  sufficient lift fan that can support all the
  parts
• We need to have the lift fan in our possession
  before we can determine the deck size
• The correct size for the axial fans will be
  determined by how much leeway we have in the
  hovercrafts weight range, which is set by the
  power of the lift fan.
• The axial fans will just have to run for short
  increments and shift the craft slightly left or
  right

Technical Stuff
This is the lift fan that we are currently
planning to use. We have not yet determined the
price but have contacted the manufacturer

Technical Contd
To the left is a P and Q cure (pressure and flow
rate) for the 3 different size fans of this
model. We are thinking of using the largest
one. Model BCB1012UH is the largest fan and the
chart below shows some of its specifications and
statistics (very bottom)

Technical Contd
This is one of the axial fans that our group is
considering using for our hovercraft. We will
have two fans one on the left and one on the
right side of the hovercraft We have not yet
determined if they will be placed in the very
back or the middle. We will decide after
experimenting with our design.

voltage for the different sizes of this axial
fan Below are the specifications for the axial
fans. We are looking at the first model,
FFB0612HHE

Technical Stuff Contd

• The base material will be Lexan.
• The skirt material will be the inner tube of a
  tire
• We have 2 rechargeable battery packs(9.6 volts
  each)

13
Summary

• Now that we have begun working on the
  construction phase we have a better idea of what
  parts the hovercraft will need.
• We have decided specifically which fans we need
  to accomplish our mission
• We have come up with 2 possible arrangements for
  the axial fans, which provides maneuverability is
  yet to be determined
• We now have a adequate, rechargeable power supply
• We know what materials we will use to construct
  our deck and skirt with

14
Future Work

• Our whole group will continue to meet Wednesday
  nights at 800 and in class as well
• The subgroups will continue to meet separately so
  that they can work on their target specific
  objectives
• Programming how to write a program to make turns
  and find/track the line
• Skirt and Body Making a strong, durable, and
  balanced deck that is leak free sealed to the
  skirt
• Lift and Propulsion Order all the fans that we
  need and other necessary parts so that we can
  start to put the craft together
