Objective The subject of the proposed project LEBox will be design of an integrated leading edge (L/E)-Box with pneumatic flow control devices for mid-scale wind tunnel testing on a suitable swept constant chord (2.5D) model. Dynamic vortex generator jets (VGJs) are chosen as the most suitable active device to control turbulent flow separation at the leading edge. The geometry of these devices in particular with respect to a swept integration will be evaluated to find important parameters such as the optimum skew angle, optimum position at the leading edge and optimum size, e.g. relative to the boundary layer. This will be done by means of comprehensive numerical simulations. The actuator geometry will be designed for the proposed (new) L/E-Box as well as for an already existing actuator system on the shroud (if a specific wind tunnel model will be used). A new L/E-Box for a swept mid-scale wind tunnel model will be designed to the point of production drawings, manufacturing (preferably by an external partner from the SFWA /WP114 consortium) will be supported. The device will be integrated with the sensor and actuator systems and tested in a mid-scale facility. For these steps background knowledge will be taken from previous or current projects as well as from the results of the numerical evaluation and from previous wind tunnel tests. The results will be analysed with respect effectiveness, efficiency and to the preparation of large-scale wind tunnel tests.
