Design and Analysis of a Subcritical Airfoil for High Altitude, Long Endurance Missions.

Abstract

An airfoil was designed using the 'inverse design' method. The airfoil was tailored to meet the requirements of high altitude, long endurance missions. The cruise Mach number was 0.65 so compressibility effects were included. In the procedure used, a basic airfoil was generated to meet the thickness and moment requirements. It was then refined to ensure desired behaviour of the boundary layer at the operating angles of attack. Computer codes designed by Richard Eppler were used for this study. The airfoil was anlayzed by using a viscous effects analysis program designed by Shang et al and a comparison was made with results obtained through Eppler's code.
