Abstract
A computer-simulation study is presented on geometric- and aerodynamics-factor screening. The optimized response is the lift for a tandem-biplane wing configuration, the so-called Henry Mignet's "Pou du Ciel" (Flying Flea) configuration. Ad-hoc software was developed as an application of the lifting surface method of vortex-rings on the assumption of incompressible potential flux. The developed computer code was verified against wind-tunnel experimental data. The study showed that the code yielded good estimation of lift values. A saturated factorial experimental design was used to estimate from computer simulations the effects of seven factors on the lift-value responses. Such initial screening was followed by a factorial design for some relevant interaction-effects between active factors. The results from screening suggest that all considered "geometric" factors, but that of wing "inflexion", may have a significant effect on lift coefficient and Clα values. The employed scheme shows the feasibility of (a) combining active parameters into dimensionless-factors to reduce the number of studied inputs, and of (b) using "expert knowledge".
