Description

The flight car with a circular wing is a vertical star tender and landing missile, also for straight ahead flight is suitable. With a high payload, it can also be under groove floor effect. The flight car can be used as conventional motor vehicle, e.g. B. used in road traffic will.

A vertical start is known from US Pat. No. 4,049,218 of the aircraft known to have a circular wing points, which is arranged above the cell. This vehicle should be used as a flight car and also as a road vehicle be. When used as a road vehicle, the circle affects round wing due to its dimensions and effects adversely affect vehicle aerodynamics.

Furthermore, conventional aircraft, ground effect vehicles, Road vehicles and helicopters known. Beyond that models of helicopters have already been introduced, comparatively small impeller in the air rotor center suck, which through the rotor blade tips together with the Engine exhaust is expelled. By the resulting Recoil, the rotor is rotated. (E.g. P.M Magazine, issue 11/1991, page 101, Gruner and Jahr AG).

Wingless vehicles that start vertically are also known are equipped with several Wankel turbines (see Moller International, 1222 Research Park Drive, Davis, California 95616, USA).

They are also predominantly used as play and sports equipment used spreading discs and throwing rings known, which by Rotation of the disc with simultaneous forward movement under a positive angle of attack. Especially good flying characteristics are shown with flat throwing rings and for panes with internal ribbing (e.g. DE 3000 758 C2 or D-patent 23 06 132 C3).

However, all known aircraft are due to the exterior Shape or due to the drive concept not for the streets traffic, especially suitable for city traffic.

The object of the invention is based on the US patent font 4 049 218 to develop a flight car that equally is suitable as an air and road vehicle.

This object is achieved by the features of claim 1.

Advantageous embodiments of the Invention specified.

The flight car has all the features of a conventional car an uplifting outer shape.  

The flight car is adjustable in the rear area Stub wing for roads or aviation equipped. During aviation it serves as a horizontal stabilizer and stabilizes the straight flight. Works while driving them as a rear spoiler to the buoyancy-enhancing outer shape of the Compensate for flight cars.

At the bottom of the flight car is a disc-like one circular wing attached. The center of this circle round wing is fixed with a central tube Impeller connected. The impeller with high speed sucked air is at the bottom of the circular Wing ejected.

The flight car starts with a lower payload than Vertical takeoff due to the recoil of the escaping air. With a high payload, the flight car starts as Ground effect vehicle, the outflowing air only one Air cushion created under the rotating disc.

The propulsion for straight flight can be done with a sideways swiveling pressure screw or a rotary turbine with Baffles are generated.

The circular wing rotates during straight flight only at low speed and acts like a Frisbee Spreading disc. Since the distance of the circular wing to Vehicle floor for this flight phase via the central tube is adjusted, the flight car can now flow around positively positioned circular wing.

The body of the flight car is shaped by that Stub wing and through the propulsion of the pressure screw or the Wankel turbine is directionally stabilized. Furthermore stabilize the gyroscopic forces of the circular wing, which preferably with a heavy metal outer ring is equipped to fly in any position.

The flight car flies along for safety reasons Motorways at heights of up to approx. 2000 m above ground. If the The flight car drives towards the rotating disc Ground. During the road trip the circular wing becomes protected by a plastic blind. (Road trip max. approx. 120 km / h).

Instead of throwing disc-like wings you can also ring-like wings are used, which are star-shaped are connected to the central tube. The max. Starting weight is with otherwise identical conditions but lower than with Use of an airfoil-like wing, as the additional air cushion effect, which is due to the interior ping of the airfoil-like wing arises, does not apply.

The invention is illustrated by the drawing Exemplary embodiments explained in more detail.

The piston motor 9 rotates the upper friction wheel 14 o and the lower friction wheel 14 u in opposite directions. The lower friction surface 13 u of the central tube 3 is pressed against the lower friction wheel 14 u by actuating 3 hydraulic cylinders 12 , which are mounted at a 120 ° angle around the tube guide 16 . The throwing-disk-like circular wing 2 , hereinafter referred to as WSKT, is continuously accelerated to high speed (approx. 4000-5000 min. ^-1 ).

The concave interior 21 of the WSKT 2 has a plurality of star-shaped internal ribs 8 . By Innenverrippung 8, a large amount of air in the central region of the WSKT 8 from below is sucked forth offset in the concave interior 21 into rotation and accelerated toward the edge. Deflected downwards by the cylindrical inner surface 22 , it is blown out conically all around from the inner region of the edge part. The outflow speed on the circumference is very even. A considerable uplift force arises from the momentum of the ring flow. The low transverse forces occurring due to the internal ribbing 8 are compensated for by countermeasures with the pivotable pressure screw 10 .

The center of the WSKT 2 is firmly connected to the impeller 4 via a central tube 3 with a relatively large diameter. By rotating the WSKT 2 , the impeller 4 is thus also rotated. At high speed, the impeller 4 sucks air from the intake shaft 19 at the top of the aircraft 1 , compresses it in the central tube 3 and presses it into air channels 5 , which also run in a star shape from the center to the edge area on the underside of the disks. The outer shape of the air channels 5 is preferably similar to that of the inner ribs 8 . The end of an air channel 5 opens into a centrifugal force-adjustable air nozzle 6 , through which the compressed air flows out at a low speed in the approx. 60 ° direction and at high speed in a approx. 30 ° direction to the axis of rotation 7 . The radial impulse component of the outflowing air causes an additional acceleration of the WSKT 2 and consequently leads to an increase in the ring flow. The axial impulse component results in a direct buoyancy.

The flight car 1 can take off vertically provided that the vehicle weight and the sum of the various buoyancy forces are favorable.

With a high payload, the ring flow together with the air drawn in by the impeller 4 merely creates a rotating air cushion on which the WSKT 2 floats.

With the hydraulic cylinders 12 , the central tube 3 is pulled down until the upper friction surface 13 o of the central tube 3 rests on the upper friction wheel 14 o. With increasing speed of the pressure screw 10 , the flying car 1 is now moved forward, the adjustable stub wing 11 as a horizontal stabilizer controlling the positive angle of attack of the WSKT 2 .

The climb is initiated by further acceleration of the flying car 1 with a strongly positive angle of attack of the flow-around WSKT 2 . The prerequisite is that the outer surface of the convexly curved area and the outer edge part of the WSKT 2 follow the outline function of two symmetrical hydrofoils.

During the gliding flight, the friction wheels 14 u / 14 o are no longer driven by the piston engine 9 . The rotation of the WSKT 2 at low speed is generated by the air, which flows through the air intake 17 together with the engine exhaust gases 20 at approximately 60 ° from the air nozzles. In emergency situations, the headwind inlet 17 can be enlarged by opening an emergency flap 18 .
