Specific Challenge:
To properly demonstrate the effect of flow control at the engine/pylon wind tunnel tests using a realistic detailed 3D model configuration under fully realistic flow conditions in terms of Mach number and Reynolds number are crucial. The model configuration will comprise a classic and an UltraHighBypass Ratio (UHBR) Turbofan nacelle with a cut back of the slats in the region of the pylon/wing, enabling a later translation of the flight test results with classic engines to the UHBR configuration. The wind tunnel tests shall be done with and w/o flow control, using pulsed jets, synthetic jets and steady blowing For the full topic description see the Call Text Document (Annex of Workplan) published with this call. |
