Abstract:

Linearized supersonic lifting-surface theory is used in conjunction with structural influence coefficients to formulate a method for analyzing the aeroelastic behavior in roll at supersonic speeds of a rectangular wing mounted on a cylindrical body. Rolling effectiveness and aileron-reversal speed are computed by using a numerical solution which incorporates matrices. Results obtained for an example configuration by using this method are compared with the results obtained by using simplified methods of analysis. For the particular configuration considered, the variation of rolling effectiveness with Mach number is found for two constant-altitude flights.
