Coupling roasting combustion method based on special roasting combustion device for propellant grain

The invention discloses a coupling roasting combustion method based on a special roasting combustion device for a propellant grain. Heat conduction heating, heat radiation heating or heat convection heating of the propellant grain is realized in the roasting combustion device, at least two heating modes in the three heating modes can be realized, and different humidity of the propellant grain canbe controlled according to actual test conditions. According to the invention, the accuracy of spontaneous combustion and spontaneous explosion of the simulated propellant due to environmental influence is improved, and the test is safe. The method provided by the invention is suitable for the technical field of propellant grain roasting combustion. 本发明公开了一种基于发射药药柱专用烤燃装置的耦合烤燃方法，在烤燃装置中实现发射药药柱热传导加热、热辐射加热或热对流加热，亦可实现三种加热中至少两种加热方式，同时可根据实际试验情况，控制发射药药柱的不同湿度。本发明提高了模拟发射药受环境影响而发生自燃自爆的准确性，并且试验安全。本发明适用于发射药药柱烤燃的技术领域。
