Abstract

The invention discloses a gun propellant dynamic combustion speed test device which comprises a body assembly, an ignition assembly, a first pressure sensor, a second pressure sensor and a data collection and processing system. The device can simulate the movement environment inside a barrel weapon chamber and can obtain combustion speed data of gun propellant on the high-speed movement and volume-variable conditions, thereby providing reliable input data for gun propellant development and weapon charge design. Influences of other trajectory factors are avoided, the influences of post-bullet space changes on gun propellant combustion are mainly researched, relevant parameters of gun propellant dynamic combustion can be precisely measured, and the gun propellant dynamic combustion speed test device fills the gap existing in the prior art.

Description

technical field [0001] The invention belongs to the field of propellant performance testing, and mainly relates to a propellant combustion performance test device, in particular to a device capable of testing the burning rate of a high-speed propellant under airtight conditions. Background technique [0002] The propellant is the power energy for the barrel weapon to complete the projectile launch. Its combustion performance directly determines the muzzle velocity of the projectile, the life of the weapon barrel and the stability of the barrel weapon launch. In the development process of the propellant used in barrel weapons, the burning rate of the propellant is generally tested by the closed detonator test method to evaluate the combustion performance of the propellant. Since the airtight detonator used in the test is a static constant volume test device, there are generally 100ml, 200ml, 500ml and 800ml models, these different types of airtight detonators can test the bur...
