17Supercritical airfoil — it has since been mainly applied to increase the fuel efficiency of many high subsonic aircraft. Research in 1940 by DVL s K. A. Kawalki led to subsonic profiles very similar to the supercritical profiles, which was the basis for the objection in …
18NACA (National Advisory Committee for Aeronautics) airfoil — A method of indicating characteristics of an airfoil. This can be done by describing the airfoil using 4, 5, 6, 7, or 8 digits. In a NACA 4 digit airfoil, the first digit expresses the camber in the percentage of chord, the second digit gives the …
19trailing edge — noun The rearmost edge of a wing or other airfoil. Ant: leading edge …
20Center of pressure — The center of pressure is the point on a body where the sum total of the aerodynamic pressure field acts, causing a force and no moment about that point. Mathematically it can be said that the net pressure force on the body acts through this… …
