Results of the overall CEA analysis indicated that the XV-5A aircraft (wing), on the basis of the preliminary data utilized in the analysis, is free of flutter within the proposed flight envelope. Studies showed that mass-balancing of the aileron is a critical factor, and must be carefully evaluated for future design efforts on the XV-5A aircraft. Similarly, the overall spring restraint does affect the flutter characteristics, but the variation, at most, will still lie above 15% on V sub L or M sub L. The flutter mode, that of antisymmetric wing bending coupled with aileron rotation, indicates that proper aircraft simulation must be used in future flutter evaluation of the XV-5A aircraft with due attention given to fuselage and/or aircraft degrees of freedom.
