Launching device for high-speed series-parallel water entry test

Abstract

The invention provides a launching device for a high-speed series-parallel water entry test, which comprises a high-pressure gas cylinder, a gas cylinder support, a high-pressure gas storage tank, a gas storage tank support, a launching pipe support and a plurality of launching pipes, and is characterized in that the high-pressure gas cylinder supplies gas to the high-pressure gas storage tank through a gas inlet pipeline, a rotary shaft is arranged in the high-pressure gas storage tank, rotary isolation fan blades are arranged on the rotary shaft, the interior of the high-pressure gas storage tank is divided into a plurality of gas distribution chambers by the rotary isolation fan blades, the gas distribution chambers are sealed through sealing structures, a plurality of outlets are formed in the high-pressure gas storage tank, each outlet is provided with agas outlet pipeline, each gas outlet pipeline is sequentially connected with a first ventilation pipeline, an electromagnetic valve, a second ventilation pipeline and a launching pipe, the rotary shaft is rotated, the gas distribution chambers supply gas to the same launching pipe one by one to realize serial launching of the structures in the same launching pipe; and the electromagnetic valve controls the simultaneous emission of the plurality of launching pipes to realize parallel launching. According to the invention, continuous high-speed serial launching of the structures and parallel high-speed launching of different structures are realized.

Description

technical field [0001] The invention belongs to the technical field of hydrodynamic high-speed water entry test, in particular to a launching device for high-speed series-parallel water entry test. Background technique [0002] With the development of science and technology, especially the upgrading of high-speed photography technology, scholars' research on water entry has changed from low speed to high speed, and from a single structure to multiple structures connected in series and parallel. For series-parallel water entry, the existing experimental devices mainly focus on the study of low-speed water entry at a speed of several meters per second through free fall, and there is a lack of research on series-parallel high-speed water entry experimental devices. [0003] For the high-speed water entry test, everyone has made corresponding design improvements to the launching device, water tank design, and test data collection. However, in the existing invention design, ther...

AI Technical Summary

Problems solved by technology

However, in the existing invention design, there is only one launch structure, but in actual naval battles, in order to destroy the target, the ship will launch several torpedoes or missiles continuously (in series) or in parallel (in parallel). The experimental research of water entry needs to be solved urgently
