摘要
In the present study, the NASA Ames code, LTRAN2 is improved in order that it may be employed to predict unsteady aerodynamic loads on an airfoil oscillating even in high frequency. The modified version presented here is based upon a two-dimensional full transonic small perturbation equation. The main modifications are obtained by adding appropriate higher order terms with respect to time, to the governing equation and to the boundary conditions.
