Multi-fragment synchronous launch sabot device and assembly method thereof

Abstract

The invention discloses a multi-fragment synchronous launch sabot device. The multi-fragment synchronous launch sabot device comprises a sabot body and a sabot separator matched with the sabot body, the sabot body comprises multiple enveloping bodies, a bracket, a base, a bottom push plate and a base sleeve, the multiple enveloping bodies are arranged on one side of the base and connected with thebase, the multiple enveloping bodies are sequentially distributed in the circumferential direction with one point as the center to form a semi-surrounded structure, the base sleeve is connected withthe other side of the base, the bottom push plate is arranged at the joint of a cylindrical barrel and a circular truncated cone barrel and is installed inside the base sleeve, and the bracket is arranged between the bottom push plate and the enveloping bodies and is installed inside the base. According to the multi-fragment synchronous launch sabot device and an assembly method thereof, the design of the multi-piece enveloping body is adopted, the experiment precision is guaranteed, enough flying space is provided for fragments, the replaceable bracket is adopted, the practicability of the device is improved, and the application range is enlarged; besides launching a large number of fragments, a plurality of shots in regular shapes can be launched by replacing the bracket; and the sabot separator adopts a threaded fastening installation mode and can be repeatedly used.

Description

technical field [0001] The invention relates to the technical field of ultra-high-speed impact loading tests, in particular to a multi-fragment synchronous launch bullet support device for a light gas gun and an assembly method thereof. Background technique [0002] At this stage, the ultra-high-speed impact damage tests of explosive fragments (velocity 300m / s-1000m / s) and space debris (velocity 1000m / s-5000m / s) 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 bullet holder matching the caliber of the light gas gun with fragments to accelerate in the barrel to complete the loading test. Due to the need for separation, the traditional bomb rest structure is only suitable for bombs with regular shapes, which limits the choice of fragment shapes and cannot meet the reality of different shapes of explosive fragments and space debris. At the same time, the high-speed impact in the ac...

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
