![]() In short, the following airfoil qualities had a major affect on pitch stability and CG range: A pattern developed in the aircraft’s response to different airfoils. Why would Burt specify an older, draggier airfoil for the Long-EZ? I learned the answer while investigating the Cozy wing using Airplane PDQ. ![]() The E1230 is a forward loaded, turbulent flow airfoil with higher drag than the GAW1. Burt then designed the Long-EZ in 1978 and selected the Eppler 1230 airfoil, which he also modified to reduce pitching moment. ![]() He modified the cusp to reduce its pitching moment, but the section remained a modern (at the time) laminar flow, high-lift airfoil. Airfoil Design “Airfoil optimization requires the application of science, intuition, and perseverance” When Burt Rutan designed the Vari-EZ in 1974, he selected NASA’s GA(W)-1 airfoil for the wing.
