AbstractAerodynamic characteristics of three dimensional wings for a wide range of Reynolds number from 10(exp 4) to 10(exp 6) have been studied using variable-pressure wind tunnels. Rectangular wing and the delta wing with NACA0012 and flat plate cross sections were tested. The wind tunnel tests show that the aerodynamic characteristics for all the wings are almost linear at high Reynolds numbers up to the angle-of-attack of stall. The aerodynamic non-linearity appears significantly as the Reynolds number decreases especially for the thick wing that have NACA0012 cross section. But the wings that have flat plate wing sections do not have such an aerodynamic non-linearity even at low Reynolds numbers.
