The Study of Effective Parameters on Burning Rate of Ammonium Perchlorate/ Aluminum/ Hydroxyl Terminated Polybutadiene )AP/ Al/ HTPB( Based Composite Solid Propellants

Performance properties of propellant such as burning and specific impulse have a great influence on the ballistic successful of the solid rocket motors. The performance properties are directly related to the combustion process. The affecting factors on the combustion process and burning rate depends on the formulation parameters (chemical nature, amount, size and distribution of raw material particles, etc.) and external factors (effects of sound waves, mixing conditions, casting, etc.). In this paper, the effects of different components of composite solid propellants formulation based on Ammonium Perchlorate/Aluminum/ Hydroxyl Terminated Polybutadiene (AP/Al/HTPB) such as oxidizer, metal fuel, binder, and additives on combustion process in the microscopic scale were investigated. The affecting factors on the burning rate and their mechanism of influence were analyzed.
