Automatic life-saving protection device and method for preventing aircraft from falling or being hijacked

technical field

The invention relates to an automatic life-saving protection device and method for preventing aircraft from crashing, falling or hijacking and forced landing, and belongs to the technical field of aviation safety.

Background technique

At present, in the field of aviation technology worldwide, the accident rate of aircraft (passenger aircraft) is on the rise. With the continuous improvement of science and technology, people have invented and used equipment or facilities such as parachutes, life buoys, life jackets and rescue chambers, and black boxes. But, the integral life-saving problem of aircraft airliner still has not solved fully. When the plane suddenly breaks down or has problems, the plane is in the process of emergency landing (falling or colliding), or is hijacked by terrorists, basically the plane crashes or is difficult to control, all of which are catastrophic accidents. Moreover, such catastrophic aviation accidents or crashes have occurred repeatedly in recent years, and they have continued unabated, and they are still unresolved.

The accident of the whole plane crashing and killing people has been bothering the safe flight of human beings, affecting people's long-distance travel or transportation, and endangering the safety of human life. How to reduce the occurrence of accidents involving overall aircraft crashes and fatalities during aircraft flight has become a major issue that has been studied and must be resolved around the world.

A method for preventing an aircraft from falling or being hijacked by the life-saving protection device. When the aircraft has a problem and needs to make an emergency landing or cannot land normally, the crew immediately presses the button of the life-saving umbrella to control the opening of the umbrella cover 3 to open quickly, and the When the umbrella protective cover 3 is opened, the system sends a message to the pop-up controller 8, and the pop-up controller 8 controls the ejector rod device to pop up, so that the flame-proof, explosion-proof and life-saving umbrella 12 pops up on the top of the aircraft instantly, and immediately opens the umbrella in the air. The airflow resists the life-saving umbrella so that it can be fully opened, forcing the aircraft to fly or fall to slow down, so as to ensure that the aircraft can land safely or minimize the loss.

As an improvement of the method for preventing the aircraft from falling or being hijacked, the said parachute-opening protective cover 3 is equipped with an independently separated flame-proof and explosion-proof positioning communication box 13, and the flame-proof and explosion-proof positioning communication box 13 is equipped with a flame-proof and explosion-proof positioning communication box 13. Box protection umbrella 14, fire-proof and explosion-proof positioning communication box 13 is equipped with satellite positioning system, signal transmitter and independent fire-proof and explosion-proof battery. The flame-proof and explosion-proof positioning communication box 13 on the upper part of the protective umbrella 12 is quickly thrown into the air. Due to the wind force, the flame-proof and explosion-proof positioning box protective umbrella 14 is quickly opened, and the flame-proof and explosion-proof positioning communication box 13 is hung in the air. The explosion-proof positioning communication box 13 just independently and continuously transmits its geographical position signal to the ground when the aircraft takes off, and the high-speed movement formed at the moment when the flame-proof and explosion-proof positioning communication box 13 is ejected quickly or the large-scale movement formed by the wind in the air. The amplitude fluctuates, causing the signal transmitter to be activated at the same time, the SOS emergency system in the box is turned on, and immediately sends a continuous distress signal to the ground command and dispatch system for up to 10 minutes.

An embodiment is provided below, the metal pipe refers to the reinforced pipe body 2, the small iron box refers to the flameproof and explosion-proof positioning communication box 13, and the life-saving umbrella refers to the flame-proof and explosion-proof lifesaving umbrella 12.

A reinforced pipe body 2 carrying the aircraft capacity is installed at the center of gravity of the aircraft, and the reinforced pipe body 2 is made of an alloy metal pipe. The metal tube is vertically inserted into the aircraft cabin, the bottom of the metal tube is fixed on the frame body at the lower part of the aircraft cabin, the upper part of the metal tube is fixed on the frame body at the upper part of the aircraft cabin, the top of the upper body in the tube is made hollow, and the hollow protective cover memory Put a high-grade flame-proof and explosion-proof life-saving umbrella that can shrink neatly. Inside the metal tube, there is an automatic ejection device and mechanism for the flame-proof, explosion-proof and life-saving umbrella. When the plane breaks down or is out of control, and the plane is about to fall, the pilot or flight administrator immediately presses the life-saving umbrella button, and the plane's life-saving umbrella pops up on the top of the plane instantly, and immediately opens the umbrella in the air, and the strong airflow withstands the life-saving umbrella . Because the life-saving umbrella pops up at the center of gravity of the aircraft body, and the aircraft is hung by four draw rings 11, these four draw rings have played a stabilizing control effect on the stability of the aircraft. Therefore, no matter how strong the wind in the air or how the wind direction changes, the aircraft still does not lose its balance, it is difficult to form an upside down or tilt, roll over, and it cannot form a free fall. The air travels and falls with the wind, thus ensuring the slow landing of the aircraft. The plane slowly lands on the land, so that there will be no crash (it will not have a violent impact on the land, cause the plane to catch fire, or damage land personnel or buildings). If the plane slowly lands on the water (ocean, river, lake), it will not sink immediately, which creates time for the escape of the crew on board and wins the opportunity for the rescue of land personnel.

Tests have proved that when the life-saving umbrella is fully extended, the falling speed of the plane will be greatly slowed down under the strong wind force in the air. At present, the brake deceleration parachute used when the plane lands can shorten the landing glide of the plane from more than 2,000 meters to 800 meters. ~900 meters. Therefore, the present invention can alleviate or avoid the possibility of the passenger plane falling directly into land, ocean, rivers and lakes or rolling in the air (controlling the center of gravity) during the falling process, ensuring the relative safety of the aircraft body or passengers. Therefore, the plane uses a life-saving umbrella, and its falling speed can be reduced by at least half, which buys time for emergency measures or emergency rescue. When there is a misoperation or the plane is falling, the plane flies normally again. The invention can automatically cut off the parachute traction rope through the button, close the parachute protection cover, and the aircraft can fly normally again.

The upper and lower parts of the reinforced pipe body 2 should be firmly fixed on the metal frame inside the aircraft body, and tightly connected with the upper and lower floors (cabins) of the aircraft, so as to ensure that the overall internal force of the aircraft is balanced when the lifesaving umbrella is suddenly opened. It can organically carry the entire body of the aircraft to prevent the body from being disconnected or other accidents. The upper part of the reinforcement pipe body 2 leads to the "protective shell" of the outer casing of the body. 4 pull rings are welded on the upper part of the metal pipe, and the pull rings are connected with a fire-proof and explosion-proof life-saving umbrella with a fire-proof and explosion-proof rope. The anti-flammation and explosion-proof life-saving umbrella is stacked under the "protective shell".

The installation positions of the four pull rings are symmetrically welded to the frame around the metal pipe at the positions calculated by the center of gravity of the machine body. The 4 pull rings are like the 4 steel claws that grasp the center of gravity of the aircraft, tightly grasping or stabilizing the center of gravity of the aircraft, so as not to make the aircraft lose its balance. Therefore, its four pull rings not only play the role of connecting the center of gravity of the aircraft with the anti-flammability and explosion-proof lifesaving umbrella, but also play a role in stabilizing the balance of the aircraft in the air (wind blowing and falling). Because not only the wind in the air is unpredictable, but also sometimes there will be lightning, thunder, and wind, snow and rain. It is difficult for any important object in the air to be manipulated.

Described reinforced pipe body 2 is the inside of the metal pipe, preferably smooth, and is equipped with an automatic promotion fire-proof explosion-proof life-saving protection umbrella, pop-up device and stretching device in the inside. There are wires in the unit that run through the inside of the aircraft to buttons in the cockpit or in the controller's cabin in the aircraft.

The reinforced pipe body 2 is the upper part of the metal pipe, which is fixed on the top plate in the body (the interior is firmly fixed with the aircraft frame). The top of the metal pipe leads to the outer casing of the upper part of the aircraft, and the outer periphery of the top of the metal pipe is welded with a metal plate, and the metal plate is fixed together with the outer casing of the upper part of the aircraft. Make a drum-type streamlined umbrella opening protective cover 3 on the aircraft upper casing. The small box of satellite positioning system and the fire-proof and explosion-proof life-saving umbrella are housed in the parachute-opening protective cover 3, and the protective shell is fixed on the aircraft outer casing. Umbrella-opening protective cover 3 can be designed as two fan-open drum-shaped doors, and the two shafts of the door are fixed on the casing with the pages removed, and the door can be locked with an automatic lock. When an emergency occurs, the pilot will automatically open the door lock of the protective shell through the button, and the two doors will be opened to both sides in an instant, and the life-saving umbrella will pop up immediately, and the umbrella will be opened in the air with the help of a strong wind.

The self-promoting fire-proof and explosion-proof life-saving umbrella device is installed inside the metal pipe. The automatic pushing device is sleeved on the metal rod in the metal tube, and the metal rod is fixed in the metal tube. The upper part of the automatic pushing device is connected with the tray with the lifesaving umbrella, and the lower part is connected with the automatic pop-up device and the electric wire button. When the firing device is fired, the compressed spring springs up instantly, and the protective umbrella on the flat plate pops out of the protective shell. The protective umbrella opens under strong wind force, pulling or hanging the aircraft.

The described flame-proof and explosion-proof life-saving umbrella must be flame-proof and explosion-proof, and must be light, durable and corrosion-resistant. The main components of the life-saving umbrella are the canopy, the paracord, the parachute opening parts, the pulling rope and the pulling rope. The canopy is made of light fabric. The towing rope is fixed on the pull ring of the metal pipe. The lifesaving umbrellas are stacked on the bottom of the protective shell in an orderly manner. The anti-flammation and explosion-proof lifesaving umbrella should be determined according to the size of the aircraft body and the carrying weight of the aircraft. Generally, it should be larger than the surrounding area of the aircraft body. When the aircraft falls, it can quickly support most of the weight of the aircraft body itself, forcing the aircraft not to fall like a free fall, reducing the acceleration of gravity, and relatively improving the safety of the aircraft. When the out-of-control aircraft reaches the ground or water surface, it will not produce violent impact or quickly sink to the bottom of the water, ensuring the relative safety of personnel.

The flame-proof and explosion-proof life-saving umbrella should be uniformly painted in yellow, which can be clearly eye-catching, and the outside of the umbrella is painted with the words SOS with obvious signs. Once an emergency occurs, when the life-saving umbrella is fully deployed, it can ensure people's early detection, identification and rapid rescue.

Simultaneously, an independent miniature fire-proof and explosion-proof parachute is stacked on the upper part of the life-saving umbrella, and a positioning communication box 13 is hung on the lower part of the parachute, and the positioning communication box 13 is made into a fire-proof and explosion-proof small iron box. device. The positioning (system) device not only has no connection with the aircraft, but the power supply must also be disconnected from the aircraft power supply. It is equipped with a flame-proof and explosion-proof battery that can be used for at least half a year. The switch of the battery power is controlled by the sound and motion of the aircraft engine. When the plane is ready to take off and the engine starts, the roaring sound of the engine and the vibration of the aircraft caused by it will connect and turn on the power switch of the positioning system in the box, and the positioning system will start the positioning work - automatically send a positioning signal to the ground dispatching command system , together with the aircraft's own locator to send a message to the ground. When an emergency occurs, the life-saving umbrella is instantly ejected, and the miniature parachute stacked on the upper part of the life-saving umbrella is quickly thrown into the air with a small iron box. Due to the action of the wind, the parachute is quickly opened and the small iron box is hung. Floating in the air with the wind, the positioning system transmits its geographic location signal to the ground. At the same time, the moment the small iron box was quickly thrown into the air, it also sent a strong SOS signal to the ground command and dispatch system. Based on the location information or irregular curves transmitted by the positioning system and the distress signal received, the ground dispatching and commanding agency immediately activates the emergency plan and organizes rescue.

The SOS distress signal sent by the fire-proof and explosion-proof small iron box is that a ready-to-go SOS distress system and an opening device are installed in the small iron box. When the small iron box is quickly ejected, the high-speed motion formed at the moment or the large-scale drift in the air due to the wind force triggers the SOS emergency system opening device in the small iron box, and immediately sends a continuous long-distance signal to the ground command and dispatch system. SOS for up to 10 minutes.

The satellite positioning (system) device in the fire-proof and explosion-proof small iron box will automatically turn off the power immediately when the aircraft does not fly or remains stationary for one hour, and its positioning system will be in a dormant state, not working or sending out signals . When the aircraft starts to fly or the small iron box is wandering in the air, it starts working again, indicating its geographical location signal and providing information for the ground dispatching command agency.
