Reduce The Double Base Propellant Pressure Index

The thesis reaserches the method,that depress NG's index of pressure.The method uses different catalyzers to reaserch the influence of NG's index of pressure,when appends them.First,the closed bomb test is used to reaserch NG that appends different catalyzers. The experimentations gain the curve of pressure and time,by the program that deal with the curve of pressure and time,the index of pressure in the different range of pressure can be attained.Variety of the index of pressure will give expression to the catalyzers to the NG's combustion.Through being compared with the NG without catalyzer,reaserch finds some good catalyzers.Second, the Differential Thermal Analysis method was used to research the thermal decomposition property of the NG with different catalyzers. And the affection of the additives will be reflected by analyzing on chemical kinetics.Through reaserch,the method that uses different catalyzers to depress NG's index of pressure is primarily found.The result of reaserch approach or primarily achieve expectant goal.
