The effects of dynamic pitch-up maneuvers on empennage buffet environments are investigated. A double delta wing model with an instrumented aeroelastic vertical tail surface is experimentally characterized for a variety of dynamic pressures, angles of attack and pitch rates. The data is characterized using statistical techniques such as the Runtest and Chi-square tests to determine stationarity and normality. Results show that dynamic response of the empennage surface under maneuvering conditions is nonlinear as a function of AoA, dynamic pressure and pitch rate. It is also shown that maneuvering conditions cause the probability distribution function of the response to become non-Gaussian. However, the system can be modeled with a local-stationarity equation based on the steady-state response equivalent. The equations are presented which can be used as a design tool for similar aircraft platforms to predit more accurate probability distribution functions of response and subsequent fatigue analyses.
