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.

Optimization of aerodynamic design of human powered helicopter

Popela R.

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

1999

nr 9

207-210

This paper deals with the application of genetic algorithm as an optimization technique to the aerodynamic design of helicopter rotor. A special kind of helicopter, human powered helicopter, is optimized as a test case. The main result of this work is a development of aerodynamic optimization tool for helicopter rotors and propellers.
