ANALYSIS

Skirt Data Bonding Method

Data from sailrite.comFrom seas.columbia.edu material and parts guide for hovercraft

Plastipane 30 Gauge Weight: 30.00 +/-1.5 oz. per sq. yardColor: ClearEmboss: Polished face and backTensile Strength (5100): 300 +/-25 lbs/in. (warp and fill)Tear Strength (5134): 7 +/- 2 lb. (warp and fill)Hydrostatic Resistance (5512): 150 +/- 20 psiElongation at break: >300%Good optical clarityFlexibleUV resistant0 degree cold crack (ASTM D 1790)

Neoprene Adhesive -- Solvent-based,

waterproof, flexible contact cement.

Bonds tenaciously. Bond strength

increases with age. Ideal for bonding

hovercraft skirt material to itself or

other surfaces, even metal surfaces.

Apply to both surfaces, let dry for 30

mins., then mate the surfaces for a

permanent bond. Clean-up with

acetone. Amber color.

ANALYSIS

Lift Data Thrust Data

Data from using Hover Hawks Lift Calculator based on Jame Perozzos Book “Hovercrafting as a Hobby” Data from hand calculations and WolframAlpha.com analysis

Given:Board Surface Area max =12.5ft^2Length: 5ft Max Width: 2.5ftPayload: 300lbs

Solved:Life Perimeter=15ftTotal Cushion Area=12.5ft^2Cushion Pressure=24 psfAir Velocity= 87.6 ft/sLift Air Volume = 55 CFSMin Lift Engine Power = 4hpMin Fan Diameter = 14” 47/64

Given:Payload = 300 lbsWanted Velocity =20mph

Using Equations:

1) Power = Pressure * Volume Flow2) Pressure = Force * Velocity

Solved:• Need roughly 4 ft^2 output at 4hp

min.• At nominal 15hp, need 1.1 ft^2

ANALYSISConstruction and materials:The board will be constructed out of 6 plys of 1/8” Baltic Birch. Using Baltic Birch will allow for a sturdy board, but still some flexibility. Titebond 3 will be used to glue the laminates together. Titebond 3 provides water resistance and a superior bonding strength. The 6 layers will be compressed together with a jig built specifically for shaping this board. Size:The board will be 5 feet long and an estimated 2.5 feet wide at the widest point. The shape is still under determination. The board will be approximately 3/4” thick. Weight:The board will be approximately 25lbs. Process:The first Baltic birch prototype will be made using a jig and purpose built clamps. Using this setup will provide the concave needed in the board. If a composite board is chosen we plan on building a male mold and using a vacuum press. Using a vacuum press will allow for even distribution of pressure of 14.7psi over the entire board. This will prevent air bubbles and provide a uniformly bonded board.
