Abstract:

Prediction of unsteady pressure distributions is an important step towards analyzing the flutter characteristics of an airplane. For this purpose, the TRANAIR code, originally developed for predicting steady transonic flow past bodies of complex geometry, was extended to handle unsteady problems, in which the unsteady solution could be viewed as a harmonic perturbation to the steady transonic flow.
