Abstract
Abstract An aircraft with vertical landing and take off capability comprising a stator having a housing for control means as well as a cockpit for operational personnel and a turbine like rotor driven by reaction jets mounted on the stator, the turbine rotor having an air inlet on the upper surface of the stator and an air outlet on the bottom of the stator with means for directionally deflecting the air outlet for control purposes; the stator also including weight means mounted along the vertical axis of the stator and displaceable radially from the vertical axis.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
An aircraft having vertical takeoff and landing capabilities comprising, a. a generally hollow housing, b. an annular turbine mounted for rotation within the housing, c. fixed reaction jet means mounted within the housing to impinge said jet upon the turbine, d. the housing having upper air inlet opening means immediately above the turbine and lower air outlet opening means immediately beneath the turbine, e. the jet means generating sufficient rotation of the turbine to induce a lift-producing flow of air downwardly through the upper air inlet opening means and outwardly through the lower air outlet opening means, exhaust from the jet means passing downwardly and outwardly through the lower air outlet opening means, f. air deflection means in the lower air outlet opening means, and g. rotational reaction-countering means on the housing positioned to balance the rotational reactive forces of the said fixed reaction jet means and the tubine.
Claim 2
Dependent Claim
149 words
An aircraft having vertical takeoff and landing capabilities comprising, a. a generally hollow housing, b. an annular turbine mounted for rotation within the housing, c. fixed reaction jet means mounted within the housing to impinge said jet upon the turbine, d. the housing having upper air inlet opening means immediately above the turbine and lower air outlet opening means immediately beneath the turbine, e. the jet means generating sufficient rotation of the turbine to induce a lift-producing flow of air downwardly through the upper air inlet opening means and outwardly through the lower air outlet opening means, exhaust from the jet means passing downwardly and outwardly through the lower air outlet opening means, f. air deflection means in the lower air outlet opening means, and g. rotational reaction-countering means on the housing positioned to balance the rotational reactive forces of the said fixed reaction jet means and the tubine.
Claim 3
Dependent Claim
56 words
An aircraft having vertical take-off and landing capabilities comprising, a. the structure in accordance with claim 1 in which, b. said air deflection means being adjustably movable to deflect the said stream of air eminating from the lower outlet opening means sufficient to counter rotatable reaction induced in the housing from said jet means and turbine.
Claim 4
Dependent Claim
64 words
An aircraft having vertical takeoff and landing capabilities comprising, a. the structure in accordance with claim 1 and b. means for moving the center of gravity of the aircraft radially with respect to the turbine including weight means mounted on a vertical shaft extending through the nominal center of gravity of the aircraft, said weight means being movable both in vertical and horizontal planes.
Claim 5
Dependent Claim
52 words
An aircraft having vertical take-off and landing capabilities comprising, a. the structure in accordance with claim 1, and b. a conduit in the housing, the conduit extending between the said upper air inlet opening means and lower air outlet opening means, c. the turbine lying within the conduit intermediate the opening means.
Claim 6
Dependent Claim
64 words
An aircraft having vertical takeoff and landing capabilities comprising, a. the structure in accordance with claim 2 and b. means for moving the center of gravity of the aircraft radially with respect to the turbine including weight means mounteD on a vertical shaft extending through the nominal center of gravity of the aircraft, said weight means being movable both in vertical and horizontal planes.
Claim 7
Dependent Claim
38 words
An aircraft having vertical takeoff and landing capabilities comprising, a. the structure in accordance with claim 5 in which b. a control means including universal mounting means for the said shaft movable simultaneously in vertical and horizontal planes.
