Description

The present invention relates to drones.

Recently, an unmanned airplane called a drone, which is controlled by a surveillance camera, a wireless communication device, and a body operation device with a small computer, has attracted attention. A commercial drone is a small machine with a total length of several tens of centimeters, equipped with about four rotary blades with a small radius, and is used for delivering packages and spraying pesticides.

Offshore voyages are equipped with lifeboats for personnel to escape, in case of fear of sinking.

In principle, drones can be cheaper because they do not carry humans. In order to reduce the price, it is quick to make the aircraft lightweight. However, if the aircraft is made lightweight, it is weak against wind. The problem is how to reduce the influence of wind.
In addition to sinking, there is a possibility that an open ocean ship may be injured due to an unexpected accident by a seafarer, or may be suddenly ill with food poisoning and cecum. There are few large ocean-going vessels carrying advanced medical equipment such as MRI and heart-lung machines.
Since the lifeboat is small, it sways greatly due to the large ocean waves and is too slow. Not useful for patients in an emergency.
It takes too much time to call the helicopter from land and transport the patient to land again. In many cases, the helicopter is rarely transported in a sleeping state, and when the sleeping state is required, the helicopter is often bundled and transported outside the helicopter. Death can occur from hypothermia. If the patient is asleep and cannot go to the hospital, it will be difficult to help.

To make it strong enough to withstand the wind, we use the keel material used on ships. A flat shape is used to allow wind to escape above and below the airframe.
Prepare a kettle material (1) consisting of a storage battery or a hollow lightweight material (titanium, carbon resin, duralumin, or polyimide. Lightening can be achieved by making it hollow. Various cables may be passed through the hollow part) in the front-back direction of the machine. The horizontal rib members (2) are fixed to the kerosene member (1) on the left and right sides at right angles to the kerosene member (1) at several positions. The lower vertical rib material (3) is fixed to the kerosene material (1) right below the keel aggregate (1) and the horizontal rib material (2). If used as a storage battery, it can be used as a standby power source. The front battery (13) described later can also be removed.
It consists of a hollow lightweight material whose major axis is the length from the left end of the left horizontal rib (2) to the right end of the right horizontal rib (2) and whose minor axis is twice the height of the lower vertical rib (3). An elliptical ring (4) is fixed to the ends of the three rib members. The ring is embedded by making a depression on the tip. Alternatively, a hole is provided at the tip end to pass the ring. A hollow rod spacer keeps a space around the top of adjacent rings. Align it with a straight line or the surface of the covering material (5).
The surface of the elliptical ring (4) is covered with a covering material (5) obtained by processing the surface of polyimide or carbon resin with Teflon so that (machine height) <(machine width) , (machine width) <(front end in flight direction) To the rear end) to form a hollow ellipsoid.
The front end of the hollow ellipsoid is closed with a transparent and removable transparent elliptical cone lid (36), and the rear end is closed with a carbon resin elliptical cone (7).
A surveillance camera, a wireless communication device (the sensitivity of which is improved when the antenna is taken out of the machine), and a small computer-equipped body operation wireless device are built in a space surrounded by a transparent elliptical cone lid (36). The surveillance camera, the wireless communication device, and the wireless device for operating the airframe with a small computer are fixed to the transparent elliptic cone lid (36) or the back side of the floor plate extended in front of the lowermost vertical rib member (3) in the traveling direction. The wireless device is used in consideration of the weight of wires, the complexity of wiring, and the difficulty of repairing after a wire cutting accident.
The floor plate (8) (total length: 3 meters, width: about 1 meter) is passed over the horizontal rib material (2) (fixed with screws so that it can be detached) and fixed. It is also possible to fix it with cemedine or double-sided tape.
An intake port (6) for intake of air is provided on the upper surface of the hollow ellipsoid.
A front battery (13) and a front electric motor (12) for operating a front compressor (11) described later, and a rear battery (23) and a rear electric motor (22) for operating a rear compressor (21) described later are provided. It is fixed so that it can be detached (screwed) on the back side of the floor plate near each compressor. For emergency, each battery is connected to all compressors. Compressors and electric motors have built-in components that transmit and receive signal waves from wireless devices. The compressor and electric motor are directly connected to the electric wire that extends from the battery.
The rear compressor (21) is detachably (screwed) fixed to the left side and the right side of the carcass (1) on the back side of the floor plate behind the rearmost vertical ribs (3) in the traveling direction.
Two on-off valves for air discharge are laid on the left side post-compressor (21). One of the valves is connected to a thrust jet (213) extending rearward. A nozzle is connected to the discharge destination of the propulsion jet pipe (213). The remaining one valve is connected to a rear downward jet (212) extending vertically downward. A nozzle is connected to the discharge destination of the rear downward jet pipe (212).
Two on-off valves are also laid on the right-side post-compressor (21), one valve is connected to the propulsion jet pipe (213), and the other valve is connected to the rear downward jet pipe (212). Connect the nozzle first.
The front compressors (11) are detachably (screwed) fixed to the left side and the right side of the keel aggregate (1) on the back side of the floor plate behind the foremost vertical rib members (3) in the traveling direction.
Two on-off valves for air discharge are installed in the left front compressor (11). One of the valves is connected to a forward downward spout tube (112) extending vertically downward. A nozzle is connected to the discharge destination of the front downward jet pipe (112). The remaining one valve is connected to a lateral jet (111) extending horizontally transversely to the carcass (1). A nozzle is connected to the discharge destination of the lateral jet pipe (111).
The front compressor (11) on the right side is also provided with two opening/closing valves, one valve is connected to the front downward jet pipe (112), and the other valve is connected to the lateral jet pipe (111). A nozzle is connected to the discharge destination of each tube.
If the intake port (6) and the compressor are connected by a pipe, the internal temperature control becomes easy.
Each compressor is driven by an electric motor.
The discharge air is discharged to the outside from the nozzle through the rear downward jet pipe (212) by the opening/closing operation of the valve installed in the rear compressor (21), and the discharged air is operated by the opening/closing operation of the valve installed in the front compressor (11). The vertical motion of the airplane is controlled by discharging the air from the nozzle to the outside via the front downward jet pipe (112).
The left and right motions of the airplane are controlled by discharging the discharge air from the nozzle to the outside through the lateral jet pipe (111) by opening and closing the valve laid on the front compressor (11).
An unmanned lifesaving aircraft characterized by operating forward movement of an airplane by discharging discharge air from a nozzle to the outside through a propulsion jet pipe (213) by opening and closing a valve laid on a post-compressor (21). ..
Even if the front part of the fuselage is turned upward and the discharge air is discharged from the nozzle to the outside via the propulsion jet pipe (213), it can rise.
The nozzle outlets other than the nozzle laid on the propulsion jet pipe (213) are in contact with the covering material (5) to reduce the protrusions as much as possible.
The lower part of the lower vertical rib material (3) is connected to the convex landing cushion (9) so that the entire keel material (1) receives the impact at the time of landing. The convex landing cushion (9) is an inflatable (rubber balloon) or low resilience urethane foam. Below the rearmost convex landing cushion (9), landing legs (10) imitating bird's feet are laid.
If you prepare low-resilience urethane foam at the landing point, you can steadily land.
When the patient is transported, a heat-insulating capsule is mounted and the patient is stored in the capsule.

Part of the batteries will be used up as an energy source for the site. When returning to Japan, it will be equipped with a sudden sick person, so it is reasonable to leave the used batteries at the site upon arrival in order to reduce the weight. Replace with a new battery when returning. If the used battery is a secondary storage battery, charge it locally. If it is a primary battery, bring it back to the onshore factory by ship and play it.
Many jet fighters can be refueled in the air. As an application, it would be possible to catch the unmanned aerial vehicle of the present invention in the air, tow it around the return point, and disconnect it.
Since heavy objects such as batteries are placed below the keel bone, the center of gravity is lowered enough for stable flight.
Further, if the horizontal width of the keel aggregate is made longer and flatter than the vertical height thereof, the resistance to the wind becomes small, and stable flight is possible.
Since there is no structure such as rib material in the space above the keel aggregate, cargo can be easily loaded and unloaded.
When jumping up, fully open only the valve leading to the downward jet. The post-compressor used for propulsion has a large output. The full output is used for jumping up. During flight, the propulsion jet pipe (213) will be slightly downward if the front part of the fuselage is flying slightly upward, so that an ascending force is produced.
During flight, the valve leading to the propulsion jet and the downward jet are opened. The opening and closing of the valves leading to the lateral jets are operated accordingly.
Even if there is no lateral ejection pipe (112) at the front of the airframe, the traveling direction of the airframe can be adjusted by operating the left and right propulsion ejection pipes (211). At the front of the fuselage, flight operation is possible with only the front downward ejection pipe (112).

In an unmanned lifesaving aircraft in means 1,
(Lower vertical rib material (3) height in the center of the flight direction) <(Bottom vertical rib material (3) height before and after the lower vertical rib material (3) in the center of the flight direction) And cover the bottom of the fuselage with a landing concave cushion (59).
To approach the conflict area, the entire surface of the airframe covering material (5), the landing concave cushion (59) surface and the elliptical cone (7) surface are covered with a dielectric wave absorbing material having a waterproof effect. The surface of the transparent elliptical cone lid (36) is covered with a transparent conductive film to improve stealth performance and is an unmanned lifesaving aircraft.
The landing concave cushion (59) is an inflatable (rubber balloon) or low resilience urethane foam.
Since the bottom surface of the central part is concave, power can be suppressed and noise can be suppressed when landing, and landing can be done like a parachute descent.
The dielectric wave absorbing material having a waterproof effect (for example, a sheet in which carbon powder is mixed with rubber) has a high waterproof effect and can fly even in the rain.
Since the surface of the transparent elliptical cone lid (36) is covered with a transparent conductive film, there is no problem in front monitoring by the camera.
By launching the unmanned life-saving airplane with various fallouts from an airplane flying over 10,000 meters at night, you can approach the destination from far behind the conflict area.

Radar detection should be made difficult to improve stealth performance.
The radio waves emitted from the radar hit the airframe and generate an induced current. Radio waves are generated from the induced current and become reflected waves. The radar receives the reflected wave. The distance between the radar and the aircraft is calculated from the time difference between the transmission time and the reception time.
In order to make it difficult for the radar to detect, the surface of the machine body should be made of a substance that absorbs radio waves and is difficult to reflect, while avoiding a low conductive metal that easily reflects radio waves. In addition it must be waterproof.
Dielectric wave absorber (patent document 1 and patent document 2. Carbon powder mixed with rubber. Carbon-containing foam urethane, carbon-containing foam polystyrene) increases dielectric loss and converts radio waves into heat to generate reflected waves. It is said to reduce. It is generally said that when an alternating electric field is applied to the dielectric, the change in polarization cannot follow the change in the electric field, and a part of the electric field energy is lost to attenuate the radio wave.
Alternatively, the cloth surface of the organic fiber may be covered with a conductive electromagnetic wave absorbing material (for example, a resin containing a highly conductive material such as carbon powder; the resin has a waterproof effect). The internal resistance of the conductive electromagnetic wave absorbing material converts the induced current into heat and reduces reflected waves.
The reflected wave can be disturbed by using a bent screen with a large number of small holes formed on the surface of the covering material or forming a saw screen.
As a transparent conductive film, there is one in which the surface of polyethylene naphthalate (thermoplastic crystalline polyester resin) is covered with indium tin oxide (transparent electrode).
If detected by radar, hovering or horizontal descent can be confusing. If it is still tracked, it will fall rapidly out of the radar range.

Instead of flammable fuel such as kerosene, an electric motor that uses a battery as an energy source provides propulsion, so even if it crashes, it is unlikely to cause a ship fire or forest fire.
Since the airframe is composed of rib material around the sturdy keel (1), even if local force is applied, it can be received by the keel (1). Since the rib material is connected to the elliptical ring (4), the stress is distributed. The wind pressure during flight is transmitted from the covering material (5) through the elliptical ring (4) to the rib material and received by the keel material (1).
The entire body is hollow and elliptical, so there is no discontinuity in the outer shape. Therefore, since the received wind flows smoothly downwind, the influence from the wind is small.
Since the outer surface of the fuselage has no protrusions such as rudders, vertical tails and horizontal tails, it is less susceptible to wind.
Since there is no airframe structure on the floor plate, there is little trouble in loading and unloading patients. In particular, since the airframe operating device is wireless, there is little hindrance to the loading and unloading of cargo and people.
Since it is possible to seal the entire body by closing the intake port, there is a possibility that it will float even if it reaches the water. Therefore, it can also be used as a substitute for a lifeboat in an emergency escape. If you don't have to think about jumping up, you can accommodate about 10 people. The unmanned lifesaving aircraft of the present invention is suitable for about one of many lifeboats.
The unmanned lifesaving aircraft should be transported to the sea area where the weather conditions where a long-distance large seaplane or helicopter can land or hover can be reached (off the coast of Nojimazaki, around the Bermuda Triangle). In order to prevent double accidents, the unmanned lifesaving aircraft should go to the dangerous waters.
Furthermore, the time required for an airplane from land to reach the patient can be shortened.
A large number of unmanned lifesaving planes of the present invention will be installed on the seaplanes and helicopters that will meet you, and if you direct the unmanned lifesaving plane to the distress ship from outside the magical waters, you will reduce the risk of secondary distress and rescue many personnel. can do.
Unmanned lifesaving aircraft with high stealth performance are also useful in radar-monitored conflict zones. The airplane of the present invention, which is driven by an electric motor, has low noise and is hard to be noticed by a person. You can glide from a high altitude to your destination, carry a patient, and fly to a safe area.
A long-distance flight is possible by attaching an infrared sensor and searching for updrafts, and then climbing on the updrafts. Or fly on a wind flow like a westerly wind.

We were able to provide a lightweight unmanned lifesaving aircraft that is not easily affected by the wind.
