leading edge of the airfoil
21Aerodynamic center — The aerodynamic center of an airfoil moving through a fluid is the point at which the pitching moment coefficient for the airfoil does not vary with lift coefficient i.e. angle of attackcite web last = Benson first = Tom coauthors = year = 2006… …
22Ice protection system — Ice protection systems are designed to keep atmospheric ice from accumulating on aircraft flight surfaces while in flight. The effects of ice accretion on an aircraft can cause the shape of airfoils and flight control surfaces to change, which… …
23Parachute — This article is about the device. For sports involving a parachute, see Parachuting. For other meanings, see Parachute (disambiguation). Parachutes opening A parachute is a device used to slow the motion of an object through an atmosphere by… …
24Pitching moment — In aerodynamics, the pitching moment on an airfoil is the moment produced by the aerodynamic force on the airfoil if that aerodynamic force is considered to be applied, not at the center of pressure, but at the aerodynamic center of the airfoil.… …

29Kutta condition — The Kutta condition is a principle in steady flow fluid dynamics, especially aerodynamics, that is applicable to solid bodies which have sharp corners such as the trailing edges of airfoils. It is named for German mathematician and aerodynamicist …
30stagnation point — The point on the leading edge of an airfoil where the airflow separates, with some going over and some under the surface of the airfoil. It is the point where the full dynamic pressure plus whatever static pressure is effective at the time will… …
