CFD analysis of commercial aircraft at high lift configuration

Popela R., Komarek M.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

2000

nr 10

153-157

The paper presents results of the CFD analysis of transport turboprop aircraft. The results obtained by means of a commercial CFD package and a developed code based on 3D unstructured grids are compared to the available data. Several wing-fuselage configurations (under cruise and high lift conditions) were studied to obtain overall aerodynamic characteristics and pressure over high lift devices at different flight and to estimate level of spoiler-aileron and flap-landing gear aerodynamic interference. The comparison between numerical and experimental results shows the agreement for solving of complex geometry typical for industrial aeronautics.
