| Abstract: |
| The coupling behavior of the imbedded weapon store occurring between the local unsteady flow field round the store and the structure response on the processing of opening its bay-door is simulated by using numerical method based on computational fluid mechanics (CFD). The transient aerodynamic behaviors when opening door under various flight altitudes and the corresponding structure deformation evolution in the unsteady flow fields are analyzed respectively and presented. The rules of aircraft attitude parameters' impacting to the responses of structure and the bay-door's opening process are obtained by comparing with the analysis results. These rules can be applied to the structure design of bay-door and route specification of missile when disengaged and launched from within store. |
