A 40 mm system projectile launching system may also be used as the launching system of the present invention, in place of the launch engine 10.

The overall working process of the embodiment is as follows:

when the simple fire control setter module works, a shooter enters a position and then sets geomagnetic geographical reference information, target position information, meteorological condition information, altitude information and shooting angles and shooting directions calculated by simple fire control to a projectile body platform by using the simple fire control setter module according to instructions of a superior command system. After the operation is finished, the shooter loads the full-reserve missile into the rocket tube, places the rocket tube on the shoulder, adjusts the launching angle to a set range through the rocket tube sighting device, activates the guidance assembly 6 and finishes the initial alignment of the inertial navigation device. The shooter pulls out the missile wing locking fuse 15 of the reverse missile wing component 1, and the missile wing opening control circuit 16 of the reverse missile wing component 1 is started at the moment; then the shooter pulls the trigger to ignite the launching engine 10, the launching engine 10 pushes the missile body to accelerate to a preset speed after being ignited, as shown in figure 1 and figure 2, the missile flies towards the opposite side of the target in the throwing stage, the launching overload generated in the process simultaneously activates the on-missile heat battery and the igniter 20 of the reverse propelling engine 5, and simultaneously the forward overload switch of the missile wing opening control circuit 16 of the reverse missile wing assembly 1 is started; after the thermal battery is discharged from the blast hole for about 0.5s, the thermal battery works normally and stably; in the flight process, the guidance assembly 6 resolves the motion states of the projectile body such as real-time position, attitude and the like in real time; after the projectile body flies to a preset position, an ignition device 20 of the reverse thrust engine 5 simultaneously ignites a reverse thrust propellant 19 and a separation powder 22; after the reverse propelling agent 19 is ignited, a thrust opposite to the flying direction of the missile is generated, so that the missile is decelerated, and flies in the direction opposite to the original speed direction, and the missile enters a deceleration attitude-adjusting stage; after the separation powder 22 is ignited, the gas generated by the ignition powder pushes out the connecting stud 23, and the front part and the rear part of the projectile body are separated. When the reverse-thrust engine 5 starts to work, a reverse overload switch in the missile wing opening control circuit 16 of the reverse missile wing assembly 1 senses reverse acceleration, the reverse acceleration is started, at the moment, the missile wing opening control circuit 16 sends an action command signal to the linear motor 14, the linear motor 14 drives the missile wing locking ring 13 to move, the missile wing 12 is unlocked, and the missile wing 12 is opened in place. At this time, the reverse missile wing assembly 1 serves as the tail of the missile, the guidance assembly 6 serves as the head of the missile, and the missile enters a reverse flight phase in the shape. After the projectile body enters a reverse flight phase, the guidance assembly 6 continues to work and continuously calculates the motion information of the projectile body; after receiving the space position information of the projectile body and the attitude information output by the attitude measuring device, the missile computer generates a corresponding control instruction by combining the flight time sequence of the missile; and the control instruction is transmitted to the electric steering engine 2, when the head direction of the missile is adjusted to point to the target, the missile enters an attack stage, and the electric steering engine 2 controls the missile body to fly along a planned trajectory until the missile body hits the target.

In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
