Abstract:

The panels of the Titan III liquid core were analyzed for flutter using the flutter criteria developed from Titan II flights. Because of the inherent conservatism build into this flutter criteria, a tolerance of 8 was applied to the criteria. Using this tolerance, no panels were found which did not meet the criteria. The conservatism of the flutter criteria is based on the fact that it is essentially a no-damage rather than a flutter criteria based on successful flights of Titan II. Additional conservatism can be attributed to the use of the maximum envelope of dynamic pressure, the neglecting of the stabilizing effect of the differential pressure across the skin, and to the relatively short exposure time during flight through the critical flutter regime. Wind tunnel flutter tests of similar panels have also shown that should flutter occur, it is of a mild variety, resulting in no damage to the panel. Author
