The nose wing cargo hold part 1 comprises a nose 101, a nose landing gear 102, a front wheel 103, a belly cargo hold 104, a rear landing gear 105, a rear wheel 106, an under-wing engine 107 and wings 108, the safety mechanism part 2 comprises a cockpit 201, a cabin 202, a tail supporting plate 203, a parachute 204, an air bag 205 and a cabin bottom jet pad 206, the tail part 3 comprises a tail rudder 301, a tail 302 and a tail 303, so that the safety mechanism part 2 is quickly separated from the nose wing cargo hold part 1 and the tail part 3, and rescue can be better carried out in the case of an air emergency through the mutual matching of structures such as the cockpit 201, the cabin 202, the parachute 204, the air bag 205 and the cabin bottom jet pad 206, so that the falling speed of the safety mechanism part 2 can be reduced, a driver has sufficient visual field, judgment and operation can be carried out according to actual conditions, the driving direction can be carried out, dangers can be avoided, and the life safety of passengers in the cabin 202 can be ensured as much as possible, thereby achieving the purpose of saving the lives of the passengers of the crashed aircraft.

In use, the bottom of the passenger cabin 202 is provided with an air injection pad 206 and a rubber anti-collision air bag 205 which is inflated with carbon dioxide and is similar to a shipboard anti-collision tire, so that the passenger cabin can play a role in buffering when falling down; the passenger cabin 202 outlets are several side inlets and outlets (including emergency outlets) in normal times; after landing, the passenger cabin 202 may be low in exit, possibly close to the ground, without the wings 103, the nose gear 102 and the rear gear 105, the front wheels 103 and the rear wheels 106, and the belly cargo compartment 104, and no slide is necessary; however, if the slide needs to be put, an emergency slide filled with carbon dioxide is prepared like a common airplane, a crew member puts the cabin door handle at a standby position at that time, then the cabin door and the emergency exit are opened, the emergency slide is automatically inflated and expanded, and passengers can sit on the elastic slide to the ground; if the emergency slide is dropped on water, the inflated emergency slide can also be used as a lifeboat or a floater.

The aircraft of the invention can be decomposed into three parts of connection, one is a device which should be fastened, released and supported, the other is a device which should be used for sliding the track, so that the parts are easy to separate, and the other is a connection device which should be used for pulling out the wire and cable plug and the oil and gas transmission pipeline, namely automatically closing, so that the leakage of electricity, oil and gas can be rapidly prevented when the parts of the aircraft are separated. The nose 101, the wing 108, the wingtip and the tail 302 should be provided with collision sensors. In terms of the separation mode, a method of separating and adding a super-strong spring (electromagnetic or flame-jet pushing and the like can also be adopted) can be used according to actual conditions, so long as the purpose of separating the airplane into three parts is achieved; in terms of time control, automatic starting and manual control can be separated; when the wing tips of the nose 101 and the wings 108 (which are the most common collision positions of an airplane) suddenly encounter impact and collision and exceed a certain force (such as impact force of more than 10 tons) or are exploded and ignited by a bullet, because a driver is difficult to react, the driver needs to set an automatic starting separation key to enable the safety structure part 2 and the tail part 3 to be separated from the nose wing cargo compartment part 1 instantly, and certainly, if the driver worrys that the automatic starting separation key can be automatically opened due to small collision or small fault, the driver also needs to have a method for closing the key, so that the separation key can be only manually operated and opened. If the disengagement key is automatically or manually started, the lock at the joint of the top of the nose 101 of the nose wing cargo compartment part 1 and the bottom of the cockpit 201 of the safety mechanism part 2, the lock at the joint of the top of the belly cargo compartment 104 and the bottom of the passenger cabin 202 and the bottom of the tail support plate 203, and the lock at the joint of the back side and the top side of the outer surface of the tail support plate 203 and the front side and the bottom side of the outer surface of the tail 302 of the tail part 3 are all released immediately, and under the action of a strong spring (or electromagnetic or flame-jet, etc.), the safety mechanism part 2 is quickly disengaged from the nose wing cargo compartment part 1 and the tail part 3 (only the nose wing cargo compartment part 1 or the tail part 3 can be arranged, which is required by airplane designers and drivers, and how the accident happens, if only the tail part 3 has a problem, only the tail part 3 can be thrown away, the safety mechanism part 2 flies back to the airport safely along with the nose wing cargo hold part 1; if only the nose wing cargo hold part 1 has problems, only the nose wing cargo hold part 1 can be thrown away, the safety mechanism part 2 still uses the tail part 3 as the micro-power safe driving direction and safely descends), then a window on the top of the passenger cabin 202 is opened, the parachute 204 inside is automatically opened, the bottom cabin air cushion 206 device at the bottom of the passenger cabin 202 is opened, the anti-collision air bag 205 is automatically filled with carbon dioxide, and the safety mechanism part 2 can slowly and safely descend. The cockpit 201 is connected with the passenger cabin 202 and is not separated, if the airplane fails, because drivers who are trained professionally continue to operate and control the landing speed and direction of the safety mechanism part and the size of the air injection at the bottom of the passenger cabin, whether the tail part 3, the parachute 204, the time and the like of the safety mechanism part are taken off or not can be regulated and controlled according to the situation, the safety coefficient is greatly improved, and the lives of passengers are guaranteed. The tail part 3 is collided and hit suddenly, when the impact force exceeds a certain force (for example, over 10 tons of impact force), or is exploded and ignited by a medium missile, because the driver is difficult to react, the automatic starting separation key is set to be better, so that the tail part can be separated from the nose wing cargo hold part 1 and the safety mechanism part 2 instantly and automatically. If the airplane crashes or encounters danger but the starting point of automatic starting tripping decomposition is not reached, the pilot can decide whether to press the starting manual control tripping key according to actual conditions, whether to throw away all the nose wing cargo hold part 1 and the tail part 3 or only one of the nose wing cargo hold part 1 and the tail part 3. If the safety mechanism part 2 falls into water after a accident and can be like a large buoy, at the moment, if the tail part 3 is still reserved, a mini engine (APU) can also be used as propulsion power and can drive away from a dangerous situation or drive to the land through the propulsion and steering of the jet pad 206 at the bottom of the cabin, so that passengers can conveniently escape from the shore; a small parachute can be pre-set on the top of the cabin near the tail. When the airplane crashes and the safety mechanism part 2 is descended, if the tail part 3 is not thrown, the parachute should be opened; however, if the tail section is thrown away, the parachute can be thrown away by the driver operating the keyboard, which makes it possible to keep the safety mechanism section 2 more balanced during the descent. If a hijack happens, because the hijack person often fails to bind the safety belt, a driver can secretly press and start the manual control airplane trip decomposition key, the hijack can be suddenly and seriously fallen down or even injured by inertia under the sudden strong trip force, and the driver and passengers cannot fall down because the safety belt is bound on the seat, so that the hijack person can be caught, the hijack crisis is resolved, and the occurrence of the similar 9.11 event in the United states is avoided.
