The torques or moments acting on an airfoil moving through a fluid can be accounted for by the net lift and net drag applied at some point on the airfoil, and a separate net pitching moment about that point whose magnitude varies with the choice of where the lift is chosen to be applied.
Aerodynamics, from Greek ἀήρ aer (air) + δυναμική (dynamics), is the study of the motion of air, particularly its interaction with a solid object, such as an airplane wing.
Aeronautics (from the ancient Greek words ὰήρ āēr, which means "air", and ναυτική nautikē which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere.
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft.
An airfoil (American English) or aerofoil (British English) is the shape of a wing, blade (of a propeller, rotor, or turbine), or sail (as seen in cross-section).
In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord.
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating.
Flaps are a type of high-lift device used to increase the lift of an aircraft wing at a given airspeed.
A gas turbine, also called a combustion turbine, is a type of continuous combustion, internal combustion engine.
A glider is a heavier-than-air aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine.
Laurence Joseph Clancy (15 March 1929 to 16 October 2014) was an Education Officer in aerodynamics at Royal Air Force College Cranwell whose textbook became standard.
The leading edge is the part of the wing that first contacts the air;Crane, Dale: Dictionary of Aeronautical Terms, third edition, page 305.
A fluid flowing past the surface of a body exerts a force on it.
In aerodynamics, lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it.
An aircraft propeller, or airscrew,Beaumont, R.A.; Aeronautical Engineering, Odhams, 1942, Chapter 13, "Airscrews".
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other conveyance that moves through a fluid medium (generally air or water).
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes.
The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge rejoins.
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion.
The turbojet is an airbreathing jet engine, typically used in aircraft.
A turboprop engine is a turbine engine that drives an aircraft propeller.
The vertical stabilizers, vertical stabilisers, or fins, of aircraft, missiles or bombs are typically found on the aft end of the fuselage or body, and are intended to reduce aerodynamic side slip and provide direction stability.
A wing is a type of fin that produces lift, while moving through air or some other fluid.
The wing configuration of a fixed-wing aircraft (including both gliders and powered aeroplanes or airplanes) is its arrangement of lifting and related surfaces.
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip.
