A test system for the whole process of heat-stimulated ammunition charge ignition and its reaction growth

Abstract

The invention provides a test system for the whole process of charge ignition and combustion reaction growth of heat-stimulated ammunition, which simultaneously monitors the temperature of the projectile body, charge temperature, internal pressure of the projectile body and expansion rate from the stages of preheating, ignition and combustion , to realize the simultaneous measurement of the temperature change, ignition response, internal pressure change history and shell expansion rate of the constrained projectile charge under thermal stimulation, and has good measurement accuracy, to solve the problem of charge response under thermal stimulation, combustion after ignition The research on the growth mechanism and the evaluation of the response intensity lack the problem of the whole process of multi-parameter complete and systematic quantitative data, which can promote the progress of the insensitive ammunition base and have good social and economic benefits.

Description

technical field

[0001] The invention belongs to the technical field of basic research on insensitive ammunition, and in particular relates to a test system for the whole process of charge ignition and reaction growth of heat-stimulated ammunition. Background technique

[0002] During the whole life of ammunition, such as storage, transportation, or service, it is inevitable to encounter accidental thermal stimulation such as fire or long-term exposure to high-temperature environments, which will cause the ammunition charge to ignite and burn until it explodes or even turns into a detonation and other typical non-shock ignition accidents, resulting in disastrous consequences. The reaction evolution process of this non-shock ignition accident is very complicated, and is affected by many factors such as the strength of the constrained structure, the inertial restraint capacity, the intrinsic intrinsic combustion characteristics of explosives, and the development and evolution o...

Embodiment Construction

[0039] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] like figure 1As shown, a test system for the whole process of heat-stimulated ammunition charge ignition and reaction growth, including cook-off test bomb, heating module, temperature test module, pressure test module, PDV test module, cooling module and processing module, wherein, bake Combustion test bomb comprises projectile body 11 and charge 12;

[0041] The heating module is used to heat the projectile body at a set temperature rise rate, so that the temperature of the charge inside the projectile body increases accordingly, until the temperature reaches the ignition point of the charge, so that ignition and combustion occurs, and the projectile body ruptur...
