Title   Design of controllable combustion solid propellant and research on its combustion principle    
Abstract
The process of designing controllable combustion solid propellant’s ingredient and the combustion characteristics of HTPB propellant under the CO2 laser radiation were studied in this paper. The main contents as follows:
(1)After the research on working substance choosing standard of HTPB propellant, designed the ingredient and made the propellants based on the ingredient.
(2) Through comparative test, the role of laser radiation in the combustion of the solid propellants was researched. The result showed that the burning rate of the solid propellants increased markedly under laser radiation.
(3)The combustion controllability of HTPB propellant was studied by using high speed photographic technique.  
(4)The effects of some factors, such as laser power densities and environment pressure, on the combustion characteristics of the solid propellant were studied. Some rules about the combustion characteristics of HTPB propellant under laser radiation were obtained. A linear function in the dependence of burning rate on the laser power densities can be obtained. Under the circumstance, the burning rate increased accordingly as the laser power density increased.
(5) The brief analysis on the combustion characteristics and combustion model of HTPB propellant.
