| Abstract: | An emulating modelling method has been applied in emulation of a complex3-D grain of solid rocket motors and calculation of its burning area.The unprecedenteddesign and analysis method,reducing numerous and difficult calculation,has been pres-ented for design of solid rocket motors.It can be used for analysis of various grain.Com-pared with the existing calculation method of burning area(ie:internal ballisticscalculation,finite-element method,boundary fitting coordinate method),this method hasadvantages of easy and flexible inputting,accurate calculating of geometric area of burningand complete output information etc. |
