| Abstract: |
| Based on the theory of fluid mechanics and the knowledge of plasma a theoretical model of electromagnetive properties of propellant exhaust plume is developed.The effect of afterburning or electron-capturing additives on electromagnetive properties of exhaust plume is modeled by application of the model together with noneqibibrium chemistry reactions. The calculation coincides with the experimental results well,the maximum error is about 10%.The calculation results showed that microwave attenuation can be reduced by additives of capturing free electron and reducing quantity of aluminium. |
