An implicit numerical scheme for unsteady gas-dynamic processes in cascades of vibrating turbine airfoils is presented. The scheme is second-order accurate in time and space and based on modified second-order Godunov’s scheme. Proposed scheme is suitable for upgrading existing explicit unsteady flow...
