Projects

The overall goal of the joint project is the development of processes or methods to perform an active, energy-efficient and robust manipulation and control of the turbulent boundary layer flow at an airfoil to a significantly reduce its drag. This manipulation of the turbulent boundary layer is effected by a controlled array of micro actuators. The task of IMTEK within the consortium is the development of a suitable actuator array. The projected requirements for the actuators with a stroke of up to one millimeter at frequencies up to a few 10 kilohertz exceed well the characteristics of previously known actuators. Therefore, there is a considerable need for research concerning the actuation principles and the structural design of the actuators.
