A frequency-domain lifting-line solution algorithm for the prediction of unsteady aerodynamics wings is presented. The Biot–Savart law applied to determine normalwash generated by wake vorticity distribution, whereas steady and airfoil theories (Glauert’s Theodorsen’s, respectively) are used evaluate sectional aerodynamic loads, namely lift pitching moment. released at trailing edge derives fro...

Analysis of the aerodynamic, thermal and aeroelasticity (including vibration) processes in gas turbine stage is principal for a design creating turbines jet engine integrally. In this article was review showed basic problems, which are solved by engineers take numerical analysis flow. The special aspects appearance vanes blades channels turbojets turbine. fundamental structure boundary layer vo...
