Active ow control can be used to improve the aerodynamic e ciency of passengeraircraft, road tra c and wind turbines amongst other applications. This workdescribes the fabrication of an ultra-compact microvalve that has been designed aspart of an active aerodynamic ow control system that generates airjets of a scaleand velocity that have been shown to have desirable e ects on the macroscopic airow. The design of the microvalve is based on criteria speci ed by the requirementsof active ow control and the piezoelectric bimorph actuator which opens and closesthe valve outlet. Cont/d.
