| STRUCTURAL DYNAMICS MODEL VALIDATION |
| DTO 257 |
| Prime: Robert Cabana | Principal Investigator: K. Schultz |
| Backup: Frederick (Rick) Sturckow |
| Overview |
| This test will excite the structural dynamics of the joined Shuttle and International Space Station (ISS) to acquire several critical natural frequencies and their corresponding structural damping. This test will allow confirmation that Shuttle primary jet control algorithm tuning is acceptable prior to attitude control which uses this algorithm. This test will be performed on several early Shuttle/ISS assembly flights for which Shuttle must provide attitude control until ISS primary structural configuration is static. |
|
|
| History/Background |
| The combined Shuttle and ISS structure after docking on-orbit has some modeling uncertainty which must be validated to be within preflight predictions. These predictions are used to certify flight readiness for structural loads and attitude control stability. |
