The Transonic Small Disturbance (TSD) equation provides a fast and efficient tool for calculating both static and dynamic nonlinear aerodynamic effects. To become an accepted part of the aircraft design process, time-accurate TSD equation solvers for aeroelastic calculations now need to be evaluated on realistic aircraft configurations that have complex geometry. Discussed here is the application of NASA Langley's Computational Aeroelastic Program - Transonic Small Disturbance (CAP-TSD) code for both static and dynamic transonic aeroelastic calculations for McDonnell Aircraft Company's F-15 and F/A-18 fighter aircraft. The results for flutter speed and aileron reversal speed are compared with results from standard linear aerodynamic analysis.
