  • Aerodynamic 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… …   Wikipedia

  • aerodynamic center — The aerodynamic center is a point on the wing chord that results in a constant moment when the wing angle of attack is changed. An AC lies approximately at the quarter chord position at subsonic speeds and at approximately the half chord position …   Aviation dictionary

  • mean chord — i. The chord of an imaginary wing of a constant section having the same force vectors under all conditions as those of the actual wing. That chord of an airfoil is equal to the sum of all the airfoil’s chord lengths divided by the number of chord …   Aviation dictionary

  • quarter-chord — The locus of all points on an airfoil or wing lying at a 25% chord. These measurements are made in the plane parallel roots along the longitudinal axis of an aircraft. Normally, the reference wing is in a clean configuration, but it includes… …   Aviation dictionary

  • Longitudinal static stability — is important in determining whether an aircraft will be able to fly as intended. Static stability As any vehicle moves it will be subjected to minor changes in the forces that act on it, and in its speed. * If such a change causes further changes …   Wikipedia

  • Lift-induced drag — In aerodynamics, lift induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting… …   Wikipedia

  • center-of-pressure travel — i. The linear distance the center of pressure travels along a chord over the entire range of angles of attack, ignoring the effects of compressibility and subsonic flow. The center of pressure moves forward as the angle of attack increases until… …   Aviation dictionary
