Problems solved by technology

This situation will bring negative effects in two aspects: one is that the projectile movement resistance caused by the belt is low, which will lead to a relatively large acceleration of the projectile’s motion at the initial stage, which will lead to insufficient combustion of the charge in the chamber; the second is the belt The fitting effect between the barrel and the barrel is not good, which in turn affects the air-holding performance of the elastic belt
The conventional elastic belt embedded in the barrel in advance cannot solve the negative effects of these two aspects

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] The invention proposes an elastic belt device for adaptively adjusting the movement resistance of projectiles, which includes an elastic belt main body including two rectangular grooves and a semicircular groove, and two elastic belt bottom brackets including rectangular bosses.

[0020] Such as Figure 1-5 As shown, the resistance adaptive elastic belt device includes an elastic belt main body 1, an elastic belt bottom bracket I2 and an elastic belt bottom bracket II3.

[0021] Limited radial relative sliding can occur between the elastic belt main body 1 and the elastic belt bottom support I2 and the elastic belt bottom support II3.

[0022] There is a T-shaped annular groove on the inner wall of the two end faces of the main body 1 of the belt, and there is a semicircular annular groove on the inner wall of the main body 1 of the belt, which is use...

Abstract

The invention belongs to the field of internal ballistic launch, and in particular relates to a resistance self-adaptive elastic belt device. Including the main body of the elastic belt, the elastic belt bottom support I and the elastic belt bottom support II, the main body of the elastic belt is cylindrical as a whole, and the two ends of the inner surface of the elastic belt main body are respectively provided with a "T"-shaped annular groove in cross section, and the middle part is provided with a The cross-section is a semicircular annular groove; the structure and size of the elastic belt bottom bracket I and the elastic belt bottom bracket II are the same. The "T" annular groove of the main body is clearance fit, and the outer surfaces of the elastic belt bottom bracket I and the elastic belt bottom bracket II are on the same plane as the outer surface of the elastic belt main body; the elastic belt main body, the elastic belt bottom bracket I and the elastic belt bottom bracket II and the outer surface of the belt groove of the bullet jointly form a semi-cylindrical closed cavity. By changing the structure of the belt device, the invention realizes the system airtight performance and the full combustion of the charge when the projectile embedded in the barrel in advance is launched, and directly improves the launch performance of the entire launch system.

Description

technical field [0001] The invention belongs to the field of internal ballistic launch, and in particular relates to a resistance self-adaptive elastic belt device. Background technique [0002] During the internal ballistic launch process, for projectiles that need to be embedded in the barrel in advance, the matching relationship between the belt and the barrel is generally a clearance fit. This situation will bring negative effects in two aspects: one is that the projectile movement resistance caused by the belt is low, which will lead to a relatively large acceleration of the projectile’s motion at the initial stage, which will lead to insufficient combustion of the charge in the chamber; the second is the belt The fitting effect between the barrel and the barrel is not good, which in turn affects the air-holding performance of the elastic belt. The conventional elastic belt embedded in the barrel in advance cannot solve the negative effects of these two aspects. Cont...
