Kind Code:
A
Abstract:
An airplane includes a wing on which a sheet of material such as canvas or the like is disposed whereby under flight conditions, the sheet material becomes inflated to provide the required lift to the airplane. An airplane body is supported under the wing and a propellor-driving engine imparts forward motion to the plane so that the on-rushing air passes underneath the wing to inflate the latter and provide the necessary lift for take-off and sustained flight.
