Simulation of flow around oscillating rotor blade section with aeroelastic flap

Autor: F. Dehaeze, L. I. Garipova, George N. Barakos, S.A. Mikhailov, A.N. Kusyumov, Rene Steijl

Publikováno v: Russian Aeronautics (Iz VUZ). 58:419-425

Flows around rotor blade sections equipped with active flaps with a degree of freedom in the flap deflection angle are considered in this paper. Results for oscillating flaps are presented. The resultant flap motion was found to couple with the unste
