High-temperature-fragment heat-conduction ignition device

Abstract

The invention discloses a high-temperature-fragment heat-conduction ignition device. The high-temperature-fragment heat-conduction ignition device comprises a body, a conduit and slide block component, a temperature measuring component, window components, decompression components, pressure measuring components, a vacuum pump, a tubular furnace, a stepping motor, a high-speed camera, a data collector and a light source. Simulative high-temperature fragments are heated to certain temperature and released onto grains produced by gun propellants, and the response process during thermal stimulus of the gun propellants can be observed and recorded. The combustion chamber space of the high-temperature-fragment heat-conduction ignition device can be changed by the silica gel pouring method, and response situations of same samples in the range of 0-10MPa (mega Pascal) under different pressure conditions are studied, so that relative property of experiments is high; through designed sealing and insulating ways among components, all the components are in threaded connection, so that mounting and dismounting are facilitated, and replaceability of the components is high; and the special decompression components for discharging air are designed to realize automatic air discharging protection under different pressure, so that safety of the device is high.

Description

technical field [0001] The invention belongs to the technical field of propellants and explosives, and in particular relates to a heat conduction ignition device for high-temperature fragments. Background technique [0002] The high-temperature fragments produced by hollow charge jets or kinetic energy penetrators are the main threat to the battlefield survivability of armored weapon systems. During the process of penetrating armor, some fragments convert kinetic energy into heat energy, which makes the kinetic energy of fragments very small, and the temperature rises further. When it enters the ammunition charging chamber and comes into contact with the propellant, the propellant may be ignited by the thermal stimulation of the high-temperature fragments, which will cause the combustion or explosion of the armored weapon system. In order to improve the battlefield survivability of the weapon system, it is necessary to develop thermal stimulation Insensitive propellants, tha...

Problems solved by technology

[0003] (1) The volume of the combustion chamber is fixed, and the filling density can only be changed by adding or subtracting the amount of drug, and the response of the same sample under different pressure conditions cannot be studied, and the test comparability is not strong;

[0004] (2) The connection of each component is a non-detachable welding method, and the maintenance and replacement of wearing parts such as transparent windows are poor;

[0005] (3) There is no pressure relief and deflation component, which is not conducive to the safety of the test
