Experimental Determination of Improved Aerodynamic Characteristics Utilizing Biplane Wing Configurations
Abstract
The purpose of this investigation was to study the effect of improving the aerodynamic characteristics of an airplane by proper orientation of a biplane wing system. Specifically, the study: 1) investigates the aerodynamic characteristics of a three-dimensional biplane cell, using nonsymmetrical airfoils, by varying the gap, stagger, and decalage angle around Nenadovitch's best point. The application of these findings will establish quantitative aerodynamic characteristic trends for three-dimensional biplane cell wings, as was done earlier for two-dimensional ones: 2) establishes maximum lift coefficient, maximum lift over drag, and drag coefficient at a cruise angle of attack, as a function of gap, stagger, and decalage angle; 3) determines wing efficiencies, and effects of the biplane on range and endurance over the monoplane.
