Drag coefficient — In fluid dynamics, the drag coefficient (commonly denoted as: cd, cx or cw) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment such as air or water. It is used in the drag equation,… … Wikipedia
Aircraft flight mechanics — In aeronautics, aircraft flight mechanics is the study of the forces that act on an aircraft in flight, and the way the aircraft responds to those forces. [Clancy, L.J. Aerodynamics . Section 14.1] Aircraft flight mechanics are relevant to… … Wikipedia

Aircraft fairing — A fairing is a structure whose primary function is to produce a smooth outline and reduce drag.Crane, Dale: Dictionary of Aeronautical Terms, Third Edition , page 206. Aviation Supplies Academics Inc, Newcastle Washington, 1997. ISBN 1 56027 287… … Wikipedia
Drag divergence Mach number — The drag divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase[1]. This increase can… … Wikipedia
Aircraft engine — An aircraft engine is a propulsion system for an aircraft. Aircraft engines are almost always a type of lightweight internal combustion engine. This article is an overview of the basic types of aircraft engines and the design concepts employed in … Wikipedia
Drag equation — In fluid dynamics, the drag equation is a practical formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The equation is attributed to Lord Rayleigh, who originally used L2 in place … Wikipedia
Aircraft — An aircraft is a vehicle which is able to fly through the Earth s atmosphere or through any other atmosphere. Rocket vehicles are not aircraft if they are not supported by the surrounding air. All the human activity which surrounds aircraft is… … Wikipedia
