Lift CalculatorThe purpose of this calculator is to provide you with the general lift air characteristics of your craft. You can use this information to help you choose the correct lift fan, or hull size, for the loads you intend to carry. The shape of your craft is assumed to be rectangular. Use the table at page : " Hull construction "to get the craft size for your required payload. If your craft is of another shape, then enter length and width dimensions that will keep the area and circumference the same as your craft (use the measurements at the ground contact of the skirt-not the hull dimensions). The air gap you will specify is the distance between the ground and the bottom "contact point" of the skirt (not the distance from the ground to the bottom of the craft) and is typically between 0.5" and 1.0".
