Propellant Static Gas Generation Simulation Study

Summarize the influencing factor of burning rate theoretically after read a great deal of literature, study how to realize the approach of propellant's progressive combustion and its controlling means, and analyze the data by typical values. Expound the insufficiency of traditionary pressure correction method in the abstract, summarize a kind of pressure correction method overall process which is true of propellant's combustion. Comparing with conventional methods, the new method present practical sense.Because there is a declension when we count the burning rate of propellant with geometry comburent law, so the notion of relative pressure impulse is introduced which correspondent statistical average thickness in the law of gasses generation, ultimately acquire theΨ-Z curve by p-t curve which is measured by closed bomb. Establish the practical model of combustion rate about propellant, and formate the software for analog calculation.Comparing with the burning rate from closed bomb,the new model erase the error caused by shape of propellant,theΨ-Z curve is inserted to the interior ballistic system of equations to count conon's parameter.
