Select an airfoil that maximises this value at the calculated optimum lift coefficient. Energy means potential energy in this case $E_$ doesn't matter). Your definition of efficiency is minimum energy loss. ![]() Since this is for gliders, the answer will be quite simple. The precise answer normally depends on your means of propulsion. But your common sense is correct in predicting that this will be a slow airplane. ![]() (Questions 5-7) With some algebraic analysis, find the effects of Airspeed. The $\alpha$=0 point on the polar would be a poor metric - there is nothing special about it, and your aircraft will not fly at this polar point when you strive for longest endurance. The relationship between airfoil thickness is the greater the thickness, the greater the CLmax and AOA are. The airfoils have been designed and analyzed theoretically and verified experimentally in The Pennsylvania State University low-speed, low-turbulence wind.
