Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] The invention proposes a segmented series self-adaptive belt device for improving the firing safety of non-equal rifled guns, which includes multiple thinner belt rings and colloid with lower peeling strength.

[0018] Such as figure 1 , five elastic belt rings with small thickness (elastic belt ring Ⅰ1, elastic belt ring Ⅱ2, elastic belt ring Ⅲ3, elastic belt ring Ⅳ4, elastic belt ring Ⅴ5), through colloid (colloid Ⅰ6, colloid Ⅱ7, colloid Ⅲ8, colloid Ⅳ9) Fix the initial relative position.

[0019] The connection between the thinner elastic belt loops is as follows figure 2 shown. figure 2 The relative position of the elastic belt ring I1 and the elastic belt ring II2 is fixed by the colloid I6, and the connection relationship between the other elastic belt rings and the colloid is similar.

[0020] As the belt moves toward the muzzle, when the b...

Abstract

The invention belongs to the field of inner trajectory launching, and particularly relates to a series self-adaptive elastic band device for improving the launching safety of a non-rib rifling artillery. A self-adaptive elastic band is formed by connecting a plurality of thin elastic band rings with the same shape and size in series, the adjacent thin elastic band rings are fixed through colloid,and the peeling strength of the colloid is smaller than 1/3 of the damage strength of thin elastic band ring material. According to the series self-adaptive elastic band, due to the fact that the peeling strength of the colloid between the thin elastic band rings is smaller than 1/3 of the damage strength of the thin elastic band ring material, the colloid bonded between the thin elastic band rings is gradually peeled off under the action of elastic band torsion force caused by rifling winding angle changes in the forward movement process of the elastic band along with rifling; and the elasticband rings can rotate relatively within a certain range, so that the problems of damage and function failure of the elastic band due to forced torsion are finally avoided, and the safe launching of projectiles is realized.

Description

technical field [0001] The invention belongs to the field of internal ballistic launch, and in particular relates to a series self-adaptive belt device for improving the launch safety of non-equal rifled guns. Background technique [0002] Projectile parts such as bullet belts are mainly used to ensure the sealing performance of the high-temperature and high-pressure gas in the chamber, increase the pressure in the chamber, and give the projectile a rotational speed during the ballistic launch process of the projectile. The structure of the belt has a significant impact on the performance of the weapon system, the stability of the projectile and the safety of the launch. [0003] At present, the common rifling structures of artillery barrels include equal rifling, progressive rifling and mixed rifling, and the corresponding bullet belts are mainly integral structures. Under the action of high-pressure gunpowder gas in the bore, the bullet belt gradually squeezes into the ba...
