Description

40mm rocket launcher is with general accuse projectile body that has of autonomy separation

Technical Field

The utility model relates to a small-bore guidance ammunition technical field, concretely relates to 40mm rocket launcher is with independently separating general accuse projectile body.

Background

A40 mm individual rocket launcher is conventional hard-attacking weapon equipment for infantry short-distance counter-personnel, tanks, armors and workers, is favored due to the characteristics of low cost, light weight, simple operation and convenient carrying, is still greatly equipped and used by various countries at present, and the total equipment amount reaches more than one million. However, all the existing ammunitions of the platform are uncontrolled rocket projectiles, and the maximum firing range is only 300m under the condition that the CEP (scattering accuracy) is 0.45 m. This greatly limits the effectiveness of the 40mm rocket mount long range combat.

The effective way for solving the problem is to develop a guided rocket projectile for a 40mm rocket launcher launching platform, and realize the accurate striking of the 40mm rocket launcher launching platform on a target far from 1500m through an accurate guiding technology, namely, components such as a control cabin are added on the original 40mm rocket projectile, and the requirement of the guided rocket projectile on the striking accuracy after the range is increased can be met. The control cabin of the missile is used for resolving the space position information of the missile given by the guidance guide or receiving component and generating a control instruction by combining the rolling attitude angle of the missile in the flying process to control the missile to fly to a target; and simultaneously supplies power to the missile electrical system. However, the special launching structure of the 40mm rocket launcher determines that the standard rocket launcher used on the rocket launcher can only adopt a flight engine and a tail wing assembly structure with the caliber less than 40mm, the space size is very limited, and in the launching process, the components of the rocket launcher positioned in the launching launcher need to bear the bore pressure exceeding 80MPa, so that the arrangement of a precise guiding and guiding or receiving assembly at the tail part is difficult to realize in the process of developing the guiding rocket launcher; meanwhile, the tail guidance guide or receiving assembly and the ultra-caliber section control cabin are in power supply and signal transmission.

One possible solution to solve the above problems is to place the guidance or receiving assembly at the ultra-caliber ring part at the rear end of the ultra-caliber section of the rocket projectile, and such a structural layout arrangement can well solve the influence of high chamber pressure on the guidance or receiving assembly. However, due to the limitation of the special structure of the rocket projectile, the guidance or receiving assembly is arranged in the middle of the projectile body, so that the guidance signal is shielded by the rear structure of the projectile body, and for a laser beam-driving guidance mode, the laser signal is not continuous due to shielding; for infrared angle measurement plus instruction guidance, blocking can cause discontinuity of ground receiving rocket projectile position information and uploading control information. Discontinuous guidance information can bring great problems to the design of a guided rocket projectile control system and the guarantee of control precision.
