| Abstract: |
| The "Generalied Coordinate Grain Simulation Method" which has been used to design solid propellant grain widely is improved in this paper.The basic geometry shapes used to simulate the surface of grain becomes more reliable and general.The mathematical treatment also becomes more simple and convenient. This method can be applied to the geometry calculation of different types of three dimensional grains quickly and accurately. The use of the method in a three dimensional slotted tube grain has demonstrated that the results are satisfactory. |
