Closed explosion test device for quantitative temperature pressure effect evaluation of thermobaric explosives

Abstract

The invention discloses a closed explosion test device for quantitative temperature pressure effect evaluation of thermobaric explosives. The device comprises a tank body, wherein the tank body is a closed double-layer tank body; a damping layer is arranged between the double-layer tank body; a vacuumizing pipe is arranged at one end of the tank body; a filling port is formed in the other end of the tank body; a sealing door is arranged on the filling port; a tank outlet is formed at the tank body on the outer side of the sealing door; sensor mounting plates are uniformly distributed on the circumference of the inner wall of the tank body; sensor mounting holes are formed in the sensor mounting plates; an air inlet pipe, an air outlet pipe and a connector are arranged on the tank body. The actual closed environment of the thermobaric explosives is simulated in the established closed explosion environment, the conditions in the explosion and after-burning process of the thermobaric explosives are met, and the closed explosion test device is suitable for an evaluation test of the temperature pressure effect of the thermobaric explosives.

Description

technical field [0001] The invention belongs to the technical field of explosives, and mainly relates to a test device, in particular to a closed explosive tank test device for evaluating the temperature-pressure effect of thermo-pressure explosives. Background technique [0002] After the thermobaric explosive is detonated, it is first the detonation reaction stage of the explosive, which produces a shock wave overpressure effect with a steep rising front, and then enters the post-combustion reaction stage, where the explosion products and fuel particles are turbulently mixed with the oxygen in the surrounding air to produce an oxidation reaction , release a large amount of heat and produce a long-lasting quasi-static pressure effect, which has a powerful damage effect on soft targets in limited spaces, and is especially suitable for dealing with living forces in buildings or fortifications. Based on the powerful killing ability of thermobaric explosives on soft targets in ...

AI Technical Summary

Problems solved by technology

In fact, the performance of the explosion effect of thermobaric explosives is not exactly the same in the free field environment and the limited space environment. In the free ground environment, the shock wave generated after the thermobaric explosive explodes spreads to the surroundings. Due to the lack of reflection barriers, the explosion shock wave decays rapidly. , it is difficult to achieve the conditions for initiating secondary combustion. At the same time, the post-combustion of detonation products, fuel particles and oxygen is only limited to the inner area of ​​the explosion fireball. It is incomplete and inaccurate to evaluate the temperature and pressure effect of thermobaric explosives only based on the shock wave effect measured by the free ground test under the environmental conditions of long-term high temperature and quasi-static pressure.
