| Abstract: | The objective of this paper is to develope an integrated grain design computer program for computation of grain geometry, including internal ballistics, grain strength and drafting display, so as to quickly perform preliminary design of solid propellant grains.
At present, one program for designing three-dimensional finocyl grains has been developed. The program is modular, and calculations are performed step by step allowing parametric studies. The use of this program in a thre-edimensional finocyl grain has demonstrated that preliminary design is available within one day on a miciocnmputer PC-286/386 and is performed with good accuracy, generality, flexibility and reliability.
This program can be applied to other grain configurations such as star, slotted tube, etc. Furthermore, an expert system can be developed. |
