Abstract

During different investigations the aircraft slats were identified as one of the major sources for airframe noise. This suggests that design modifications of the wing especially the slats could reduce aircraft noise. For this purpose different wing model configurations from a standard to a slatless wing were designed. Within the German Aerospace Center (DLR) project LEISA these wing configurations will be investigated. The wind tunnel measured lift and drag coefficients can be integrated in the fast time flight simulation tool (NAPSim) developed by DLR. With this tool it is possible to simulate noise abatement flight procedures flown by generic airplanes. The tool has an interface to the DLR noise calculation software SIMUL to compute and compare the different noise impact produced by these configurations. Furthermore the simulation can calculate economical aspects like time and fuel consumption, which are used to evaluate the different configurations, because one constraint is to achieve nearly the same performance that results from a standard wing design. In this paper the calculation of flight paths and the flight mechanics of an airplane with different wings and thus resulting noise is described.
