Description

Technical Field

[0001] The present invention belongs to the field of airdropping, and particularly relates to a gravity airdropping method applicable to a combat vehicle airdropping system. Background Art

[0002] Currently, the combat vehicle airdropping system adopts the traction airdropping method: as Figure 1 and Figure 2 shown, the combat vehicle airdropping system includes a central guide rail located in the cabin, a mechanical lock installed at the lower front side of each combat vehicle, a main parachute system installed on the top of each combat vehicle, and a drag parachute system provided at the front side of each combat vehicle. The parachute pack of the first drag parachute system is installed on the cabin door, and the parachute ropes are traction-connected to the mechanical lock of the first combat vehicle. The parachute packs of the remaining drag parachute systems are installed at the rear of the previous combat vehicle, and the parachute ropes are traction-connected to the mechanical lock of this combat vehicle. The mechanical locks on the same combat vehicle are traction-connected to the main parachute system. Initially, the lock shaft of the mechanical lock is inserted into the central guide rail for limiting, and the combat vehicle is fixed. After the cabin is opened, the first drag parachute system is opened to form a traction force, which unlocks the mechanical lock of the first combat vehicle and pulls it out of the cabin. At the same time, the mechanical lock of the first combat vehicle pulls the main parachute system of the first combat vehicle to deploy. Then, the first combat vehicle drives the second drag parachute system at the rear to open to form a traction force, and the second drag parachute system unlocks the mechanical lock of the second combat vehicle and pulls it out of the cabin. The mechanical lock of the second combat vehicle pulls the main parachute system of the second combat vehicle to deploy, and so on, gradually driving and pulling all combat vehicles out of the cabin.

[0003] When using the above combat vehicle airdropping system for traction airdropping, the landing point range is calculated according to the three-piece continuous airdropping mode. The landing field range of the three pieces of equipment is about 3 kilometers, and the landing points of the equipment are relatively scattered. It can be seen that there are problems such as a wide landing range, slow combat vehicle assembly, and low combat efficiency in the existing combat vehicle airdropping system under the condition of continuous airdropping. Summary of the Invention

[0004] The purpose of the present invention is to provide a gravity airdropping method applicable to a combat vehicle airdropping system. This method can achieve the gravity airdropping of combat vehicles only by making a little improvement to the existing combat vehicle airdropping system. The interval time between combat vehicles leaving the aircraft in sequence is short, and the landing points are relatively concentrated. All improvements are concentrated on the attachment parts of the combat vehicle, without the need to improve the combat vehicle itself and the cabin. The improvement is convenient and the cost is low.

One end of the pilot chute rope is slidably hung on the original parachute-opening steel cable in the cabin without coming out, and the other end is connected to the pilot chute pack. The canopy of the pilot chute is accommodated in the pilot chute pack, and the connecting rope is connected to the main parachute system; initially, the lock shaft of the electronic lock is inserted into the central guide rail for positioning. After reaching the predetermined airdrop area, the aircraft flies at an elevation angle, the cabin door is opened, all the electronic locks are synchronously unlocked, and the combat vehicle slides out of the cabin under the action of gravity. After the combat vehicle exits the cabin, the pilot chute rope opens the pilot chute pack to expose the pilot chute, and after the pilot chute opens, the main parachute system is opened.

[0007] Further, the electronic lock includes a lock body, a lock shaft and a power component. The lock shaft is slidably fitted on the lock body, and the power component is used to drive the sliding of the lock shaft. The power component is powered by a battery module.
