Development of smart vortex generators

Two concepts for Smart Vortex Generators have been designed, constructed and tested. The first is based upon the use of Shape Memory Alloy, whereas the second makes use of a pneumatic actuator. Experimental wind tunnel tests were undertaken using Fluorine Flow Visualisation in order to investigate their performance. It was demonstrated that both concepts enabled full control of the vortex generator angle for all speeds up to 35 ms-1.
