Abstract

The herein invention is presenting a lift generating method based on a semi-open fluid jet flowing in a closed circuit around a lifting airfoil. A VTOL aircraft with maximized pay load room and car-like shape is the preferred embodiment of the invention. The herein aircraft uses no wings, exposed propellers, hot gas jets or other high injury risk means for propulsion and life, and it can be driven by ordinary skilled people. Furthermore the aircraft has a small footprint and can land, take off and even cruise on water in one of the preferred embodiments.

Claims

1. A lifting method using a regenerative semi-open fluid jet with an airfoil surface that creates lift by circulating on an expose to the outer medium airfoil surface and returns on the closed side of the airfoil to the source of the jet, where the source is mounted between the closed side of the airfoil and a containing body, which containment body hermetically contains the fluid jet on the return path and allows the exposure of the fluid jet to the outer medium on the open side of the airfoil.

2. A lifting surface apparatus that is based on the method of claim 1, comprising of an airfoil that is rigidly connected to an outer body in such way that a fluid jet generated by a jet source contained between the airfoil and the outer body can circulate in a close path around the said airfoil;

and the containing body hermetically guides the fluid jet on the return path around the closed side of the airfoil and allows the fluid jet to be in contact with the external medium when flows on the open side of the airfoil, therefore creating lift on that open side of the airfoil.

3. A lifting element comprising one or more lifting surfaces as described in claim 2, which can achieve VTOL and horizontal flying when connected to a power source and control unit, and furthermore can be the propulsion system of a car-like aircraft when connected to a car-like cabin including the power source, control unit driver and passenger'"'"'s seats and payload room.
