quarter-chord point
1quarter-chord point — The point on the chord line at one quarter of the chord length behind the leading edge. Sweepback is usually quoted by the angle between the line of the quarter chord points and the normal to the aircraft fore and aft center line …
2chord position — The position defined by the location of a quarter chord and the inclination to the aircraft x y plane; a point being defined on primary centerline coordinates. Chord position is described in relation to X and Y axes …
3Chord (music) — Instruments and voices playing and singing different notes create chords. This article describes pitch simultaneity and harmony in music. For other meanings of the word, see Chord. A chord in music is any harmonic set of two–three or more notes… …

6Center 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… …
7Airfoil — 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… …
8Pitching 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.… …
9Aerodynamic 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… …
10Center of mass — In physics, the center of mass of a system of particles is a specific point at which, for many purposes, the system s mass behaves as if it were concentrated. The center of mass is a function only of the positions and masses of the particles that …
