Abstract
A lift-fan airplane lands vertically on dirt, kicking up debris but bringing a landing pad for use by others. The landing pad comprises many long slats hinged to each other at the sides. The slats are of generally increasing widths for rolling up into a tight spiral. This compact state allows low-drag air transport. After landing, the spiral is unrolled. A central slat has two stub axles sticking out the ends. Two men place a large wheel onto each stub axle, then push on the wheels to unroll the landing pad on the ground. An upturned wall at the end of the pad deflects upward the downwash from landing lift-fan VTOL airplanes, creating a shadow zone free of flying debris. This creates safe parking for massed operations. Inflated balloons, wedge-shaped to streamline necessary protuberances, detach and fill any large potholes under the landing pad.
