• 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

• Center 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… …   Wikipedia

• center-of-airfoil movement — The point about which the basic airfoil moment coefficients are given, usually the aerodynamic center of one quarter of the mean aerodynamic chord …   Aviation dictionary

• Aerodynamic potential flow code — Aerodynamic potential flow or panel codes are used to determine the velocity and subsequently the pressure distribution on an object. This may be a simple two dimensional object, such as a circle or wing and it may be a three dimensional vehicle …   Wikipedia

• Aerodynamic Park — The Aerodynamic Park (Aerodynamischer Park) of the Humboldt University in Berlin Adlershof was once part of the German Johannisthal Air Field. Laboratories, motor test beds, wind tunnels and hangars, erected in the 20s and 30s, are historical… …   Wikipedia

• aerodynamic damping — Whenever in flight maneuvers result in rotation of an aircraft about or near its center of gravity, a restoring moment is created by the changed relative airflow. This restoring moment opposes the control demands, and it arrests maneuvers as and… …   Aviation dictionary

• 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

• aerodynamic forces — The forces on a body moving through a gaseous medium. In an aircraft, the thrust acts forward, drag acts rearward, and lift acts vertically upward. The weight of an aircraft produces a force that acts vertically downward. The tailplane also… …   Aviation dictionary

• aerodynamic stance — In order to create less drag, the vehicle is lowered closer to the ground. This improves the flow of air over the vehicle. A better aerodynamic stance helps the vehicle to go faster when it is going in a straight line as well as give better fuel… …   Dictionary of automotive terms

• center-of-gravity limits — The fore and aft limits of the center of gravity expressed as a percentage of the mean aerodynamic chord. See center of gravity envelope …   Aviation dictionary
