Fluctuating pressure provides an important basis for the analysis of structure response and for the study of the dynamics environment. A new technical approach is presented, by which numerical simulation of the mean fluid field is integrated with the engineering prediction model based on experiments. For the transonic rotated aircraft, the surface fluctuating pressure environment is analyzed and predicted. And the fluctuating pressure coefficient curves and the power spectral density curves are presented at different transonic Mach numbers and different angles. The results essentially accord with the experiment results.
