In the Common Research Project (CRP) HiLiNo (High Lift Noise), the DLR Institute of Aerodynamics and Flow Technology is working together with the French research company ONERA on the experimental and numerical quantification of pre-wing noise. These so-called slats of an aircraft, are aerodynamic bodies that can be extended at the leading edge of the wing to increase lift at low speeds - for example, during takeoff and landing. The slat is one of the most powerful sound sources of a high-lift system. In order to be able to predict the overall noise of the aircraft and reduce it in the future, it is important to correctly simulate the sound generation by the slat. HiLiNo is the conclusion of a more than 10-year series of CRP's and follows the CPR's LEISA II and SWHAILI with a measurement of the F16 high-lift system in the Low-Speed Wind Tunnel Braunschweig (NWB) and numerical simulations of the model setup. Following the measurements in the NWB, the project participants will evaluate the results in order to create an acoustic reference data set, which will make it possible to determine correction methods for measurement data from small acoustic wind tunnels or small anechoic measurement sections.
