Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] figure 1 (a), 1(b) are cross-sectional views of the structure of this embodiment along its axial direction. Such as figure 1 (a), shown in b, according to the bullet that has helical deceleration device of the present invention comprises housing 1, empennage seat 2, helical wing 3, wing pin shaft 4, fuze 5, medicine box 6, push rod 7, Shear pin 8 and drive disc 9.

[0040] The casing 1 is a hollow structure, one end of the shape is a cylindrical barrel, and the other end is a conical barrel combined with one end of the cylindrical barrel, so as to ensure a good aerodynamic shape of the bu...

Abstract

The invention discloses a bullet with a helical deceleration device, comprising: a tail wing seat mounted on the tail of a casing, which evenly defines a plurality of grooves along the circumferential direction; a helical fin, comprising a fin and a fin seat arranged at the end of the fin. The pivot seat has gear teeth, which are accommodated in the groove; the fuze is installed in the hollow hole inside the tail wing seat, and the medicine box is accommodated therein; Racks are opened on the spaced prism surfaces, and the edge surfaces of the racks correspond one-to-one with a plurality of grooves on the tail wing seat; after the fuze is ignited, the charge box is detonated, and a force is generated to push the transmission disc to move axially, so as to pass through its outer surface. The rack drives the pivot seat meshed with it to rotate, so that the helical fins are spread by covering the surface contour of the bullet shell, and the helical deceleration of the bullet can be realized under the action of aerodynamic force. The invention adopts the helical fins to realize the effective and stable deceleration of the bullet, and solves the problems of complex structure and low reliability of the existing bullet deceleration device.

Description

technical field [0001] The invention belongs to the technical field of submunitions, and in particular relates to a bullet with a deceleration device. Background technique [0002] The submunition is a carrier with a certain number of bullets inside. After launching, the mother bullet opens the cabin at a predetermined position and throws bullets to complete the ammunition for destroying targets and other special combat tasks. Submunitions can be used to damage cluster tanks, armored vehicles, technical equipment, etc., and can also be used to deliver leaflets and rescue supplies, etc., which can effectively deal with cluster targets, expand the range of action of the warhead, and improve combat efficiency. There is a wide range of applications on the warhead of artillery shells and the like. [0003] Due to the special ballistic characteristics of the sub-munition, the bullet is usually accompanied by high-speed and irregular motion after being thrown out of the parent bom...
