Aerodynamic Testing of Wing Sections Using the Laser Doppler Velocimeter

Abstract

An experimental program was conducted in the wind tunnel to ascertain velocity distribution about a wing section at various angles of attack using a laser Doppler velocimeter (LDV) and conventional pressure measuring techniques. In addition, an analytical method was developed to determine the pressure distribution over an arbitrary airfoil surface given the geometry and coefficient of lift. The results of the different measurement techniques are compared with the analytical computations. Agreement between experimental data and fluid flow theory was obtained.
