Propellant grain cook-off device

The invention discloses a propellant grain cook-off device which comprises a heating cylinder with a heating function, end covers are detachably connected to the two ends of the heating cylinder respectively, and the two end covers are rotationally connected with fixing mechanisms used for fixing a propellant grain and monitoring the temperature of the propellant grain respectively. One of the twofixing mechanisms is in transmission connection with a driving mechanism arranged outside the heating cylinder, and a first temperature sensor, a humidity sensor and a safety pressure release valve are installed on the heating cylinder. The device has the characteristics that heat conduction and heat radiation heating of the propellant grain can be performed, the operation is safe, and the service life of each part is long. The invention is suitable for the technical field of propellant grain cook-off. 本发明公开了一种发射药药柱烤燃装置，包括具有加热功能的加热筒，于所述加热筒的两端分别可拆卸连接有端盖，两端盖分别转动连接有用于固定发射药药柱并用于监测发射药药柱温度的固定机构，两所述固定机构择一与设于加热筒外的驱动机构传动连接，于加
