Abstract:

Aluminum containing solid propellant will produce a large number of aluminum oxides and protoxides in the combustion process. Understanding the physical and chemical characteristics of combustion products is of great significance to the fine research of combustion， flow and multi physical processes in the motor and to solving the safety problems in the combustion process. In this paper， the physical parameters of aluminum and alumina， chemical reaction parameters of aluminum and oxygen， carbon dioxide and water vapor， specific heat capacity and enthalpy of formation of protoxide of aluminium such as AlO， Al₂O₂， Al₂O， AlO₂， and reaction heat， activation energy and pre-exponential factor of AlO reacting with oxidizing components were investigated. The experimental test and theoretical calculation methods and results at different temperatures at home and abroad are reviewed. The physical and chemical characteristics of multi-phase combustion products in the motor are comprehensively studied.
