THE USE OF CFD IN THE REDESIGN OF A MODEL SCALE ROTOR FOR THE INVESTIGATION OF STALL ONSET AND ALLEVIATION FOR THE UKVLN ROTOR RIG

摘要

An experimental setup has been designed to example in the effect of rotor blade stall flutter. The blade has to be designed so that it does not exceed the maximum permissible load on the rotor rig to be employed for wind tunnel tests, while maximising the blade loading to allow for the blade to be excited. An original set of blades where first tested to examine the possibility of their reuse. On discovery that they required too much power drive them at the required collective computational fluid dynamics (CFD) was used to aid a new design.
