A kind of multi-fragment synchronously launching magazine and its assembling method

Abstract

The invention discloses a multi-fragment synchronously launching bomb support device, comprising a bomb support body and a bomb support separator matched with the bomb support body. The bomb support body includes an envelope body, a bracket, a base, a bottom push plate and a base The sleeve is provided with a plurality of enveloping bodies on one side of the base and are respectively connected with the base. The plurality of enveloping bodies are circumferentially distributed around one point to form a semi-enclosed structure, and the base sleeve is connected with the other side of the base. The bottom push plate is installed inside the base sleeve at the connection between the two, and the bracket is installed inside the base between the bottom push plate and the enveloping body. The invention adopts the design of a multi-piece envelope body, which ensures the experimental accuracy, ensures sufficient scattering space for fragments, and adopts a replaceable bracket, which improves the practicability of the invention and expands the scope of application. In addition to firing a large number of fragments, it can also fire multiple regular-shaped projectiles by changing the bracket. The ejector separator adopts the screw-fastening installation method, which can be used repeatedly.

Description

technical field [0001] The invention relates to the technical field of ultra-high-speed collision loading tests, and in particular relates to a multi-fragment synchronously launching catapult support device for a light air gun and an assembling method thereof. Background technique [0002] At this stage, the impact damage of explosive fragments (speed 300m / s-1000m / s) and space debris (speed 1000m / s-5000m / s) hypervelocity impact damage tests in the laboratory are mainly based on light gas guns. However, since the caliber of the light gas gun is not adjustable, it is necessary to use a magazine matching the caliber of the light gas gun to cooperate with the fragments to accelerate in the gun barrel to complete the loading test. Due to the need of separation, the traditional ejector support structure is only suitable for projectiles with regular shapes, which limits the choice of fragment shapes and cannot meet the reality of different shapes of explosive fragments and space fr...

Problems solved by technology

[0004] Purpose of the invention: To solve the above problems, that is, to solve the problem that the existing bullet holder can only launch a single fragment to simplify the projectile, and many experiments are required to simulate the high-speed impact of a large number of fragments, resulting in experiments that cannot reflect the real damage of high-speed fragments and seriously affect the test data. In order to solve the problem of accuracy, the present invention provides a multiple irregular fragment synchronous high-speed firing bullet support device for light gas guns, and provides its assembly method
