  • Skirt Data Bonding Method Data from sailrite.com From seas.columbia.edu material and parts guide for hovercraft Plastipane 30 Gauge Weight: 30.00 +/-1.5 oz. per sq. yard Color: Clear Emboss: Polished face and back Tensile Strength (5100): 300 +/-25 lbs/in. (warp and fill) Tear Strength (5134): 7 +/- 2 lb. (warp and fill) Hydrostatic Resistance (5512): 150 +/- 20 psi Elongation at break: >300% Good optical clarity Flexible UV resistant 0 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.
  • 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^2 Length: 5ft Max Width: 2.5ft Payload: 300lbs Solved: Life Perimeter=15ft Total Cushion Area=12.5ft^2 Cushion Pressure=24 psf Air Velocity= 87.6 ft/s Lift Air Volume = 55 CFS Min Lift Engine Power = 4hp Min Fan Diameter = 14 47/64 Given: Payload = 300 lbs Wanted Velocity =20mph Using Equations: 1) Power = Pressure * Volume Flow 2) Pressure = Force * Velocity Solved: Need roughly 4 ft^2 output at 4hp min. At nominal 15hp, need 1.1 ft^2
  • Cost Analysis Material/Tools quantity Price Total Price 15 hp engine 1 $299 $299 Board material $100 Skirt material 54in*1yd $9.98 $9.98 Nuts & Bolts 1 $17.99 $17.99 Metal Rod 2 $7.67 $15.34 Total $442.31
  • Construction 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. 3-point Bending Analysis
