Description

technical field [0001] The invention belongs to the field of microwave technology, in particular to an ignition powder device. Background technique [0002] In the artillery launch technology, the traditional ignition method has the disadvantages of low ignition efficiency and insufficient combustion. The application of laser ignition and plasma ignition technology in recent years provides reference and reference for the improvement of ignition technology. However, laser ignition has the disadvantages that the ignition channel is easy to be polluted, and plasma ignition has a large plasma generating device, which limits its application in emission. Contents of the invention [0003] The object of the present invention is to provide a device for igniting propellants to realize high-efficiency, safe and reliable ignition. [0004] The technical solution that realizes the object of the present invention is: [0005] A pointing propellant device is characterized in that it ...
