• Airfoil — An airfoil (in American English) or aerofoil (in British English) is the shape of a wing or blade (of a propeller, rotor or turbine) or sail as seen in cross section. An airfoil shaped body moved through a fluid produces a force perpendicular to… …   Wikipedia

• Aerodynamic force — Forces on an aerofoil. Aerodynamic force is exerted on a body by the air (or some other gas) in which the body is immersed, and is due to the relative motion between the body and the gas. Aerodynamic force arises from two causes: [1] [2] …   Wikipedia

• NACA (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 …   Aviation dictionary

• Slip (aerodynamic) — A slip is an aerodynamic state where an aircraft is moving sideways as well as forward relative to the oncoming airflow. In other words, for a conventional aircraft, the nose will not be pointing directly into the relative wind . Flying in a slip …   Wikipedia

• mean aerodynamic chord — The chord of an imaginary regular airfoil having the same force vectors under all conditions and throughout the flight range as those of an actual wing. Practically, it is very close to a mean chord …   Aviation dictionary
