The invention relates to a warhead structure for improving the ballistic stability of a projectile penetrating a concrete target plate, which belongs to the technical field of a projectile penetrating a concrete target plate, and solves the problem of easy deflection of the ballistic trajectory when the projectile structure penetrates a concrete target plate in the prior art technical problems. The projectile structure of the present invention comprises a projectile body, the front end of the projectile body is provided with a first circular platform, the diameter of the upper bottom surface of the first circular platform is smaller than the diameter of the lower bottom surface of the first circular platform; the outer surface of the first circular platform is provided with a plurality of ribs along the generatrix direction of the first circular platform The end of the rib far away from the first circular platform is the front end of the rib, and the other end of the rib is the rear end of the rib; the height of the front end of the rib is greater than the height of the rear end of the rib; the diameter of the rear end of the rib is equal to the first circular platform Bottom diameter. The invention can suppress the deflection of the projectile and improve the ballistic stability of the projectile penetrating the concrete target plate. At the same time, when the ballistic stability is improved, the lateral force and moment acting on the projectile are reduced, which is more conducive to preserving the projectile and the fuze.

The invention discloses an aircraft guidance system and method for realizing the landing angle constraint. The system can firstly set the launching angle of the aircraft by inputting the desired landing angle and target distance coordinates; Then measure the sight angle of the projectile of the aircraft in real time, and transmit the measured sight angle of the projectile to the guidance law calculation module in real time; the guidance law calculation module solves the problem in real time according to the measured sight angle after the aircraft starts control. The guidance law is calculated, and the calculated guidance law information is transmitted to the execution module in real time; the execution module can control the movement of the aircraft according to the calculated guidance law information, thereby completing the present invention to realize the landing angle constraint of the aircraft.

The invention discloses a heterogeneous integrated safety system applied to a small-caliber bomb and an implementation method thereof.

The invention relates to a warhead active fragment with a sealing layer and its preparation method and application. In the invention, firstly, the fluoropolymer composite material is injected into a pipe with an inner wall grid by hot pressing. Due to the flow of the polymer It can fully match the shape of the unit cell of the pipe with the inner wall grid and fully seal. Secondly, fluoropolymer composites can also stimulate chemical reactions during high-speed collisions, further improving damage efficiency. The traditional method of pressing a pipe with an inner wall grid into a steel end cap requires high processing accuracy for the cooperation between the end cap and the pipe. The pipe material of the inner wall grid simplifies the process and improves the production efficiency.
