The Study of Gun Propellant Self-ignition Test

摘要

A experimental method of measuring thermal self-ignition of propellant in different humidity is introduced. Thermal self-ignition times of single base propellant and double base propellant in different humidity are measured by this method. The experimental result is discussed and analyzed. The heat self-ignition tests of some gun propellants in the stack containers with diameter 50 ～300mm were carried out. The self-ignition times at given temperature have been obtained and compared with those in the stack container with diameters 37 ～ 85mm.under the different humidity condition. It is shown that the Self-ignition of propellant depend on thermal and humidity effect
