A fluidic sensor system for the reliable detection of flow separation at low speed was developed, manufactured and tested in view of flight application.

It comprised an optimised combination of fluidic micro sensors as well as a multichannel measurement system including sensor control and calibration as well as data acquisition and communication electronics.

Starting from different types of fluidic micro sensors and combinations thereof, the sensor system development was performed with the aim to provide a robust and reliable measurement tool for flow control operations in view of flight tests. Ability for flush mounting and easy integration was essential for the sensor front end. The readout electronics should be designed for minimum space and low power consumption. The whole sensor system was examined in view of reducing complexity and was integrated and tested in preparation of a large scale wind tunnel test and in view of flight.

Such a sensor system was expected to be the basis for monitoring and validation of the function of open loop separation control systems and at a later stage the essential control input for future closed loop flow control systems in high lift applications.

These provided a new potential for fuel saving, noise reduction and safety.
