As has been observed in Chapter 3, aeroelastic phenomena can have a significant influence on the design of flight vehicles. Both theoretical and computational methods of analysis are covered. This course provides an in-depth treatment of the fundamental mechanisms behind various types of aircraft flutter instabilities and other aeroelastic phenomena. If in the analysis of these structural dynamic systems aerodynamic loading is included, then the resulting dynamic phenomena may be classified as aeroelastic. Theoretical and Computational Aeroelasticity. In particular, the mechanical systems considered were one-dimensional continuous configurations that exhibit the general structural dynamic behavior of flight vehicles. Ashley in Principles of Aeroelasticity (John Wiley and Sons, Inc., 1962.)Ĭhapter 2 dealt with the subject of structural dynamics, which is the study of phenomena associated with the interaction of inertial and elastic forces in mechanical systems. … There is no evidence that flutter will have any less influence on the design of aerodynamically controlled booster vehicles and re-entry gliders than it has, for instance, on manned bombers. Achievements include flutter suppression and gust load and buffet alleviation developments, active flexible/aeroelastic wing development, contributing to flight flutter clearance, and launch vehicle dynamics assessments. Stiffness criteria based on flutter requirements are, in many instances, the critical design criteria. The branch has a rich history of aeroelastic experimentation, analyses, and computational accomplishments. … The flutter problem is now generally accepted as a problem of primary concern in the design of current aircraft structures. The pilot of the airplane … succeeded in landing with roughly two-thirds of his horizontal tail surface out of action some others have, unfortunately, not been so lucky.
