Abstract Conducting thermal safety research on solid rocket motors is a method to effectively improve the battlefield survivability of rockets and missile weapons. Based AP-based cock-off reaction mechanism, 2-D unsteady axial symmetrical model motor developed. The software Fluent used calculate numerical value under stimulation conditions different heating rates. results indicate that rate coo...

Abstract In order to design a solid rocket motor with high mass ratio, it is necessary find out the parameters of grain shape meet structural strength under volume loading fraction condition. A rapid optimization method for complex motors based on parametric modeling and GA-BP proposed. Based this, neural network prediction results are optimized as function fitness in GA, show that maximum Von ...
