The present chapter is focussed on different measurement techniques for in-flight experiments. Laminar flow investigation for low and high flight velocities were performed. Several types of surface sensors were used for detection of laminar-turbulent transition. Methods for acquiring information about boundary conditions like angle of attack, flight velocity and pressure distribution are an essential part of this work, too. The method of delaying laminar-turbulent transition by active boundary layer control was transferred from wind tunnel experiments to a glider in real flight. For this purpose, a sensor actuator system was developed and, together with a realtime controller, applied to a glider.
