ABSTRACT:
An air vehicle has a passenger section, a tail section including variable camber air foil wings and horizontal and vertical control surfaces, ducted fan propellers and landing gear wheels driven by an engine. The landing gear wheels accelerate the vehicle until the fans produce sufficient thrust, at which time the ducted fans propel the vehicle into flight. In one embodiment, while the tail section is detached, the passenger section can be used as a land vehicle. Alternatively, the passenger section and tail section are formed as a single unit in which case the vehicle is used solely as an airplane.
