| Problems Concerning the Natural Vibration Characteristic Calculation of Solid Propellant Rockets |
| Li Yunfeng, Zhou Kejian |
| Abstract: |
| According to incomplete statistics，85% of existing rocket-missile weapon systems either in use or in the design stage are powered by a solid propellant，therefore，studies for improving computing precision and speed in determining the natural vibration characteristics of solid propellant rockets are of practical engineering worth.
On the basis of the results of solid propellant tests and actual measurement on dynamic characteristics of solid propellant rockets in our university and in the light of theoritical calculations made by the authors of this paper，we put forward a proposal for improving computer precision and speed，which includes assumptions and selection of vibration computational theory. |
