| Abstract: | n solid propellants,the porous solid propellants with ultra-high burning rate are greatly different from general solid propellants in burning mechanism. The ignition of porous solid propellants with ultra-high burning rate are more difficult than that of general solid propellants. So long asthe parameters concerning igniting performance should be selected properly. When propellant density,ignition space and nozzle throat size are determined, the key factors to affect ignition are the weightand the type of igniter's charges, the material and the thickness of nozzle closures. The concerned experimental results for igniting research on porous solid propellants with ultra-high burning rate are also given in this paper. |
