Abstract:
To study the combustion stability of base bleed unit under rapid depressurization,a simulating test equipment and a high-speed digital video recorder are used in the systematic researches of combustion of composite base bleed charge(AP/HTPB) under instantaneous depressurization.The results show that the instantaneous combustion can be classified into three categories,i.e.reignition,oscillation combustion,and irreversible extinguishment.The initial pressure and the depressurization velocity are the core factors that determine the combustion characteristics of composite base bleed charge.Based on the results,the characteristic time formulation of combustion gas is conducted by unsteady combustion system.
