eng Abstract:
In order to study the aeroelasticity in a blade cascade experimentally, simplifications must be made to make any measurements possible. Therefore, most researchers use linear cascades: parallel blades with constant cross-sections which essentially reduce the problem to 2D. Although linear cascades lack some key features such as rotational periodicity and the radial flow component, it is still possible to obtain and study aeroelastic couplings. The aim of the experimental cascade presented in this paper is to include the radial flow component by creating a bypass flow loop on the wind tunnel and having deformable blades fixed on one side only. When such blades oscillate, the channel width between the blades changes unevenly along the blade span. This experimental setup allows the effect of 3D flow in a blade cascade to be studied.\n
