Abstract

The invention relates to a shock tunnel diaphragm rupture device and belongs to the hypersonic shock tunnel engineering field. The shock tunnel diaphragm rupture device includes a gun barrel connection structure, a cone supporting plate, a diaphragm rupture cone, a high-pressure cavity pipeline, a low-pressure cavity pipeline, a shock tube high-pressure section gun barrel, a shock tube low-pressure section gun barrel and a diaphragm; the left side of the gun barrel connection structure is fixedly connected with the shock tube high-pressure section gun barrel; the right side of the gun barrel connection structure is fixedly connected with the shock tube low-pressure section gun barrel; the cone supporting plate is fixedly installed in the gun barrel connection structure; the diaphragm rupture cone is axially and fixedly installed at the axis of the cone supporting plate through the gun barrel connection structure; the high-pressure cavity pipeline and the low-pressure cavity pipeline are arranged at the outer wall of the diaphragm rupture cone along the radial direction of the gun barrel connection structure; and the diaphragm is fixed between the gun barrel connection structure and the shock tube low-pressure section gun barrel. The diaphragm rupture of a shock tunnel can be both realized under high driving pressure or low driving pressure, diaphragm rupture time is significantly shortened, and the controllability of the diaphragm rupture process is high.

Description

technical field [0001] The invention relates to the field of hypersonic shock tunnel engineering, in particular to a shock tunnel diaphragm rupture device. Background technique [0002] The shock tunnel is a special hypersonic wind tunnel. The shock tunnel is to increase the total temperature of the wind tunnel through the compression of the shock wave. The shock tunnel structure is very simple and the cost is relatively low. With the modern test The development of technology, which can undertake most of the hypersonic aerodynamic and aerothermal measurement tests, plays an increasingly important role in the development of the new model's aerodynamic shape. The high-pressure section and low-pressure section of the shock wave tunnel are separated by a diaphragm. Through the sudden rupture of the diaphragm, the driving gas in the high-pressure section drives the test gas in the low-pressure section to form a shock wave to complete the experiment process; The rupture of the me...
