Abstract

To provide a flying object which does not have disadvantages of conventional helicopters capable of performing a vertical flight by rotating a rotor using a gas turbine engine and decelerating rotation thereof: that the gas turbine is heavy and expensive; and that flight depending on only one main rotor is risky because failure of the main rotor will instantly cause crash.SOLUTION: The time has come when automobiles are driven by electricity, and soon the time will come when aircrafts are driven by electricity, as well. To fly for long hours, fuel cell generation is to be used to obtain electric energy for flight. Rotating turbo fan engine (1) by respective electric motors (15) can finely control output with high reliability, and the fuel cell generation produces no harmful exhaust gas. Electricity can be obtained from fuel cells (3) with a suitably selected number of cells. Four fans can be rotated by respective electric motors to allow a light flying object to fly quietly and safely. Thus, electrically-driven flight may become possible and the new generation flying object can be provided.SELECTED DRAWING: Figure 1

Description

    A flying object that changes to a helicopter allows vertical take-off and landing, making it easy to fly. Electricity is generated by using a fuel cell using hydrogen and oxygen in the air as an energy source, and a fan is rotated at high speed with an electric motor as power, eliminating the need for a conventional gas turbine. The engine becomes much lighter, and there is no expensive gas turbine, and a highly reliable electric motor can fly with motive power. By using multiple fans, it is possible to fly with a large wind pressure. In addition, since it does not require thermal power because it is electrically operated, it will provide a new generation vehicle that does not generate harmful exhaust gas.

    In the present invention, hydrogen automobiles that are operated with the power of a hydrogen fuel cell are also commercially available in recent years. Noisy helicopter rotor blades are too dangerous and expensive. Since the present invention is driven by a general-purpose electric motor and is operated by several engines, the safety can be improved and the maneuverability can be simplified. If charging is sufficient, it is possible to fly over short distances using only electricity, but if hydrogen is used as high-pressure gas or liquid hydrogen, long-distance flights are also possible.

  The main rotor of a general helicopter is driven by a fan jet engine and is rotated at a low speed by a large speed reducer to increase the rotational force. Heavy weight and fuel costs. A flying object that can be easily maneuvered, cheaply manufactured, light, safer and easier to maneuver. It is a flying object that can be taken off and on without choosing a place and can be easily operated like a car, and can be obtained by ordinary people.

  By generating electricity with a fuel cell using hydrogen, high electric power is possible, and flight is possible for a long time. Hydrogen is the lightest element, so the weight of the fuel is light. The transmission for deceleration is not necessary, and there is no overhead rotor like a helicopter, so it becomes quiet, and the turbofan engine (1) of the present invention can be electrically driven to fly by aerodynamic force and take off and landing anywhere. As shown in Fig. 1, the number of turbofan engines can be increased to 4 or several so that the aircraft can be more stable, move forward and move straight ahead, and the production cost of the engine does not use a gas turbine. It is also cheaper and good for global warming because the fuel gas is used and the combustion gas does not generate heat.

  By flying electrically, the structure is simple and the manufacturing cost is low. Since the turbofan is rotated by electricity, it becomes easier to control the output electrically by using a new jet engine, and the aircraft is lighter and cheaper. Unlike a plane, this flying object can be used to save lives on isolated islands and mountains because it can be used where there is no runway and no road. Since the aircraft can go close to the building, it can be especially effective for building fires. It becomes a new vehicle and can be expected to play an active part in the event of a disaster.

Fig. 1 Perspective view of flying object When the number of seats is five, the flying object is levitated by four units with the turbofan engine (1) of the air facing upward. The fuel is stored in two spherical high-pressure double tanks (2) using high-pressure hydrogen gas or liquid as fuel. Oxygen is generated from the air and is used as electric energy of a flying object using a commercially available solid polymer fuel cell of hydrogen and oxygen fuel cell (3).
A dedicated pilot controls the cockpit (9). The body (10) is lightly made of glass fiber resin or aluminum. It is a lightweight aggregate such as duralumin in the chassis (11) of the fuselage.

Fig. 2 Plane with flying object The aircraft is protected by the outrigger (12) while the body (10) is placed on the chassis (11) as seen from the elevation and side view. Two high-pressure double tanks (2) for hydrogen of fuel are mounted at the rear.

  Fig. 3 System diagram of the flying object Hydrogen is compressed to high pressure, depressurized from the spherical high pressure double tank (2) by the pressure reducing valve (26), controlled by the control valve (27), and enters the hydrogen-oxygen fuel cell (3) Power is generated by electrochemical reaction. Air is pressurized by the air blower (28) to a constant pressure of the control valve (27), electricity is generated by the combination of oxygen and hydrogen in the air, and the electric power is determined by increasing or decreasing the number of cells of the fuel cell. The lithium battery (4) temporarily stores electricity. Increase the voltage with the power unit (5). Appropriate flight control is carried out by a computer of a control panel (7) which converts it into an alternating current by a three-phase converter (6) and converts it into a three-phase alternating current in order to make the motor input 200V. A lever that controls the aircraft with the control can (8). Since hydrogen gas and liquid are replenished at high pressure in the spherical high-pressure double tank (2), the safety valve (29) is necessary. When flying for a long time using liquid hydrogen as a fuel, the liquid is vaporized by an electric heat or the like by a vaporizer (33).

Fig. 4 The figure of the electric turbofan engine (1) and the internal structure in half section. The electric motor (15) drives the fan at high speed. The fan (17) has two stages. In order to further increase the pressure for sending air, the fan (18) is raised again by the fan (18) and the air is turned in a three-stage system to increase the pressure. A structure that reduces the area and increases the flow velocity near the exit of the engine. There is a blade (19) for protecting the electric motor (15) from rain and dust with the motor cover (16) to protect the engine body from birds and foreign objects. The ball bearing (20) is a high-speed bearing and can be unpaid or lubricated.

New industries such as new aircraft industry and pilot training.
Police, fire departments, hospitals, rescue teams, and other current helicopters can be changed. Goods and people can also go to remote islands and mountains that have no runway. It can be used as an empty taxi, and it can be used at low prices and can save lives. It can also be used for sightseeing because it can be used for observation in agriculture and fisheries to see things in three dimensions.
