Lift producing system for aircraft - has endless rotating belt with wing profiles for ensuring vertical lift

摘要

The vertical lift producing bodies are installed on aircraft or spacecraft for ensuring vertical takeoff and landing. The lift is applied directly on the aircraft fuselage by a lifting bodies fitted on fuselage upper part. Conventional power units are used for propulsion. The lift is provided by individual aerodynamic wing profiles held on an endless belt moved by a driving wheel. The upper part of this belt is open and lower part is enclosed. The belt assembly can be tilted for increasing lift. The belt may be stopped for horizontal flight.
