A simulated load rear section and rear load section connection structure and its assembly method

Abstract

This invention discloses a connection structure and assembly method for the rear section and rear load section of a simulated load. The connection structure includes a tension block and screws. The tension block is disposed in the central square hole of the rear load section shell, away from the rear section shell. Two screws pass through the through holes of the tension block and are fixed to the connection between the rear section shell and the rear load section shell by a fixing mechanism. This invention utilizes the spatial structure between the rear section shell and the rear load section shell, and sets up the tension block and screws to provide reinforcement for the connection between the rear section and the rear load section of the simulated load. When the simulated load is subjected to a strong impact during high-speed parachute opening in the air, the connection structure between the rear section and the rear load section provided by this invention can ensure a reliable connection between the rear section and the rear load section.

Description

Technical Field

[0001] This invention belongs to the field of underwater weaponry, specifically relating to a connection structure between the rear section of a simulated load and the rear load section, and its assembly method. Background Technology

[0002] In the live-fire tests of the torpedo-assisted flight, to obtain test data similar to that of a live torpedo launch, simulated loads were used to simulate the torpedo's shape, mass, moment of inertia, and other structural and aerodynamic characteristics. This allowed for the testing, recording, and playback of experimental data. To save costs, the design of the simulated loads was required to be as simple and reliable as possible. Because the new lightweight torpedo uses a wedge-ring connection, the connection between the rear section and the rear load section experiences significant stress. The existing simulated loads' rear section and rear load section lack sufficient impact resistance, which could lead to breakage at the wedge-ring connection of the rear section casing. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a connection structure between the rear section of the simulated load and the rear row of load sections and its assembly method. The connection structure utilizes the existing space and structure of the rear section of the simulated load and the rear row of load sections to solve the problem of fracture at the wedge ring connection of the rear section shell under the impact of high-speed parachute opening in the air of a torpedo-assisted flight.
