Abstract
A vertical lift aircraft includes a central cabin and a set of concentric, circular, counter-rotating power blade assemblies. Gas turbine engines located in the central cabin provide power for rotating the power blade assemblies to cause lift and motion of the aircraft. The turbine engine exhaust gases are directed through a rotatable exhaust nozzle for aiding in the thrust and momentum of the aircraft. The gas turbine engines drive electric power generators which provide the necessary power for operation of the aircraft.
Claims6
An aircraft capable of vertical take-off and landing comprising:
- (a) a substantially disc-shaped body having a cross-section generally in the shape of an airfoil;
- (b) a central cabin located in the center of the body;
- (c) a pair of concentric, circular power blade assemblies disposed within said body, wherein the power blade assemblies are positioned one above the other, and wherein each power blade assembly comprises;
- (i) a first circular band generally disposed around the periphery of the disc-shaped body and a second circular band generally disposed inward of the periphery and surrounding the central cabin;
- (ii) a plurality of rotor blades extending generally radially outward from the center of the disc-shaped body and fixedly secured between the first and second bands, wherein the rotor blades are oriented at a fixed angle in relation to the flow of air through the power blade assembly and to the direction of rotation of the power blade assembly such that the air flows in a single direction;
- (iii) a plurality of roller bearings securely positioned above and below each circular band;
- and
- (iv) controllable means to adjust the bearing pressure compressing each set of bearings;
- and
- (d) means located in said cabin to cause the pair of power blade assemblies to rotate in opposite directions.
