EXPERIENCE IN AERODYNAMICAL TESTS AND CFD SIMULATIONS OF OVERSIZED WING DEMONSTRATOR IN LARGE LOW-SPEED WINDTUNNEL

摘要

The subsonic aircraft wing demonstrator is designed and produced by the consortium in the frame of FP7 SARISTU project. To change the morphing wing shape electrical actuators are used. The demonstrator morphing concept is provided by deflection of leading edge (EADN), trailing edge (ATE) and winglet trimmer (WATE). Experimental investigations in the large low-speed wind tunnel (WT) T-104 (TsAGI) with opened test section are carried out in order to demonstrate the wing devices operation.The numerical simulation of the flow in WT with model installed is carried out in the Reynolds equation system framework with EWT-TsAGI [1] software jointly with the experiment. Computational model created for experimental investigations modeling consists of isolated wing, wing in the WT (Fig. 1), peniche without wing, as well as WT nozzle and diffusor. As a result of calculations additional characteristics are obtained. This allows to estimate an influence of WT flow boundary and experimental setup elements (peniche, sting) on wing integral loads.The research leading to these results has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration under grant agreement no 284562.
