Hovercraft Air Cushion Calculator
This hovercraft calculator will
provide you with the general lift air requirements of your proposed hovercraft
design. Use this information to assist in choosing the correct lift fan, pressure fan
or hull size, for the gross weight you intend to transport.
The shape of your hovercraft is
assumed to be rectangular. A length to width ratio of 2 to 1 is the most stable size
and shape for a hovercraft. If your hovercraft is of another shape (round, oval, etc.),
then enter an estimated length and width dimensions that will be approximately the air
custion area of your craft.
Use the measurement from the
ground contact point of the hovercraft skirt, not the hovercraft hull dimensions.
The air gap you will specify is the distance between the ground and the bottom
"contact point" of the hovercraft skirt to the ground, not the distance
from the ground to the bottom of the hovercraft, and is typically 0.5 inch.

Thanks are given to Alex Olshove for developing this
calculator based on James Perozzo's book, Hovercrafting as a Hobby.
Additional credit is given to Juergen Schoepf for incorporating metric units of measure
into this calculator.
