## Title
Vertical take-off and landing aircraft

## Abstract

A vertical take-off and landing aircraft has an airframe body that defines a loop-shaped path of travel for a plurality of movably-mounted wings that are transversely disposed relative to a longitudinal axis of the aircraft. The airframe body has two side frames that are transversely spaced apart in parallel relation to one another and interconnected by a pair of fixed wings that do not follow the path of travel of the movably-mounted wings. A passenger compartment is positioned between the two side frames and within the loop traveled by the movably mounted wings.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an airplane that no runway is necessary and it can vertical takeoff and landing on the land, the water and the snow and characterized in a method of generating lift.
2. Background Art
Since a current jet plane generates lift by accelerating propulsion power of a very long wing, it requires very large propulsion power and is accompanied with an economic loss, increase of a cost for complete equipment.
A horizontally long wing occupies surplus area other than minimum utilization for passenger and freight and requires a large hanger, and thus it cannot be a familiar transportation.
Since a jet plane requires an airfield with a long runway and noise pollution of a high power engine, it requires a vast place in an inconvenient remote area and needs to construct terminal buildings. It also requires a wasteful expense and time to go to and from place and incidental facilities investment for transportation such as buses and trains.
Although the jet plane is suitable for a long-distance trip to foreign countries and characterized in its high speed and mass transport, since it cannot make small turn, it is not adequate to transportation for domestic, short distance.
A helicopter can vertical takeoff and landing, however, a large hangar is required because of its very long rotor.
Takeoff and landing on a residential area is difficult and the spread to the public is limited because of the noise of a high power engine.
Car-oriented society has approached the limits as follows.
A. Increase of car accidents and a bodily injury and generation of a traffic jam caused by cross moving on the same plane (road).
B. Social and human cost, economic loss and strong pressure of mental strain caused by frequency of accidents.
C. Uneven distribution and waste of a huge financial investment such as a highway construction, a tunnel digging and signal equipment.
D. CO2 emission, global warming and early coming of depletion of resources caused by mass consumption of fossil fuel.
E. Social anxiety of health hazard and larger burden of medical expenses caused by exhaust gas.
F. A traffic congestion caused by an accident of drowsy driving of trucks with unbroken tension in long-distance service.
G. An accident induced by a structural defect in opposite action of the right foot and instant judgment of a throttle and a brake.
H. Economic and social loss, storing of stress, etc. caused by a speed restriction and a traffic jam.
SUMMARY OF THE INVENTION
Problems to be solved are that the present invention is characterized by a method for generating lift, and since it can vertically takeoff and landing from a home garden and a building rooftop and does not scatter dust to a neighborhood, it can be active in every place such as desert, a skiing area and water surface. It is suitable for forest fire extinction because of its quick water absorption and for safety and quick escape guiding with respecting for human life if a road is destroyed in the brunt of the earthquake, and it has wide range of activity in personal, family and every industrial world as well as another competent authorities, and thus it can solve the problems which has approached limits in car- and airplane-oriented society of the twentieth century as a new trinity transportation system on the land, water surface and in the air.
Propulsion power and lift are not generated at near its center of a existing propeller but are generated at a peripheral part that cuts air in high speed. Consequently noise pollution is caused by amplification of noise of a high power engine and wind noise at ultra high-speed in confrontational wind speed at a propeller end. In the method for generating lift in the present invention, since whole wing of plural rotary wings is evenly rotated at a constant speed, whole surface of the wing and each wing independently can generate lift, and thus it does not disturb the neighborhood by noise pollution and the wind pressure as well as triggering the simultaneous action of lift and propulsion power.
Since, it provides simple body structure, low cost of body manufacturing, flight by a small power engine and a size of a little larger than a car, it does not require a surplus area other than utilization for passenger and freight like a long wing jet plane and a helicopter and a large hanger. Therefore, it can expect of the spread as a private plane for all over the world (developing countries and remote islands).
The axis is attached to the wing to be the rotary wing. The axis(axes) of plural rotary wings are rotated in the paths of both sides, and the wing generates a lift in moving upper forward of a path wall and attenuates the same in moving lower backward.
In this method, since lift is not generated by propulsion power like a jet plane but is generated by rotating wings in standstill on the land (or the water), propulsion for takeoff is conducted after airframe weighting becomes around zero, and thus it can almost vertically takeoff and landing without a runway.
Since lift is generated by the rotary wings at almost whole area of the airframe and the whole lower area of the airframe can be used for passenger and freight compartment, there are no long things such as a main wing of a jet plane and a rotor of a helicopter, and thus the area of the whole airframe dose not become large.
It can on-site response by reducing occupation area for passengers when it is always used in a small group and by coupling and building more same planes when it is used for mass transport.
In slow flight and taxiing, it can use front lift by entering the rotary wing having changed angle of approach into the path for moving forward lower in front of the main axis.
No runway is required and if the forward thereof is open, it can takeoff and landing from a home garden and a building rooftop, and thus it has promise as near future transportation of domestic and short distance.

The effect that the present invention brings to future society is great. Since it requires little investment expense for infrastructure improvement such as highway construction, tunnel digging and road incidental facilities, it does not require a very long runway like a current airport, a terminal building and transportation for access, it can eliminate a traffic jam, frequent accident, loss of access to an airport and noise pollution, and it is characterized by its small size, the method for generating lift and vertical takeoff and landing, “Wing Rotary” is a new future trinity transportation which can freely navigate on the land, the water and in the air.
Since whole upper area of the airframe is covered with wings, it can make a soft-landing safely in a crash due to machine fault. Thus, it can fly in peace and safely if rare accident happens.
It is suitable for forest fire extinction because of its quick water absorption after landing on the water. It can quick escape guiding with respecting for human life if a road is destroyed in the brunt of the earthquake.
It also suitable for takeoff and landing on the water, the snow and desert because it does not blow on the ground.
Since a cockpit and a entrance can be separated completely in a coupled plane, it cannot be hijacked, and thus it is safely operated. In the case of mass transport, there is the convenience of immediate on-site response by coupling and building more same planes.
