| 21 | Lift generating method and apparatus for aircraft | US732637 | 1991-07-19 | US5240204A | 1993-08-31 | Bernard P. Kunz |
| A lift generating method and apparatus for aircraft is provided which generates lift in forward flight, in vertical flight or while hovering. A disk (24) is positioned between first and second counterrotating blade assemblies (22 and 36). The disk (24) generates lift in vertical flight or while hovering due to radial flow of air over an upper surface (28) thereof. In forward flight, the disk (24) functions as a fixed wing to generate lift. The assemblies (22 and 36) may be rotated to provide equal and opposite torques so that a torque compensating tail rotor is unnecessary. | ||||||

| In a vertical take-off and landing craft, a pair of nested dome-shaped shells are spaced apart and rigidly interconnected by struts. The outer shell has a central opening formed in its top, and the shape of the shells is such that the space between the two shells progressively widens from the central top part of the shells to the peripheral bottom part of the shells. A circular series of arcuate airfoil units is disposed in the annular space between the bottoms of the shells, and is driven in rotation by an engine mounted on the inner shell. Upon rotation of the circular series of arcuate airfoil units, low pressure is generated above the airfoil units and high pressure below, such that air is drawn down through the central opening of the outer shell to produce a thrust which permits vertical displacement of the aircraft. | ||||||

| An apparatus for producing lift in a flying vehicle comprising a top deck of a flying vehicle having a cylindrical well formed thereinto, a discoidal member positioned within the cylindrical well, an air intake system formed in the center of the discoidal member for drawing air through the discoidal member for use elsewhere in the flying vehicle, and a labyrinth member formed on the periphery of the discoidal member for restricting the clearance between the discoidal member and the wall of the cylindrical well. The discoidal member is adapted and powered for rotating within the well. The top deck has a generally flat exterior surface. A fluid passageway extends through the interior of the flying vehicle for passing air from the air intake system. The discoidal member has a flat top surface generally parallel to the top deck of the flying vehicle. The top surface of the discoidal member is positioned within the well below the upper surface of the top deck. A second discoidal member is positioned within the fluid passageway at a location adjacent the bottom of the well. The second discoidal member is coaxial with the first discoidal member and connected by a common spindle. The common spindle is rotatably powered by the prime mover means. The labyrinth comprises of plurality of rimmed cavities positioned so as to be in close proximity with the wall of the well for the first discoidal member and the wall of the fluid passageway for the second discoidal member. | ||||||

| Thrust or carrying force generates a tubular fluid jet, which is created in that a fluid after radial acceleration in a disk-shaped driven rotor (11) mixes with another fluid (28, 32) in the peripherally disposed annular chamber (20) before being deflected in a nearly axial direction. | ||||||

| The flying/lifting mechanism consists of a moving object, a static object, and a driving mechanism. When the moving object moves relatively to the static object, the pressure reduction on surface of the static forms the lifting force. Variety of applications of lifting mechanisms was disclosed in this invention. | ||||||
