Patent ID: 7766274

Claim:
An apparatus for flight comprising: an elongated airfoil portion having a tip end and a root end defined in longitudinal direction and a leading edge and a trailing edge defined in transverse direction; a body portion rigidly affixed to the root end of the airfoil portion; a propulsion means for generating a thrust jet of pressurized gas, the propulsion means provided within the body portion and the airfoil portion; a thrust delivering orifice located near the tip end of the air foil portion for delivering the thrust jet of pressurized gas away from the leading edge and along a tangent to the tip end of the airfoil portion, wherein the apparatus' center of mass is located in the body portion whereby the thrust jet of pressurized gas causes the body portion and the airfoil portion of the apparatus to rotate together about the center of mass and enables the airfoil to generate lift for the apparatus; and at least one upwardly-directed jet provided immediately adjacent to the trailing edge of the airfoil for delivering a flow of gas for adjusting the lift of the airfoil, wherein the flow of gas is a portion of the pressurized gas generated by the propulsion means that has been redirected to the at least one upwardly-directed jet.
