WebIn aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag … WebIn aerodynamics, drag refers to forces that oppose the relative motion of an object through the air. Drag always opposes the motion of the object and, in an aircraft, is overcome by … matt henson on facebook
THE COEFFICIENT OF LIFT/DRAG CURVE - Aviation …
WebJun 20, 2024 · Drag has two components: induced drag and parasitic drag induced drag is directly related to lift production and is greatest at low speeds and high angle of attack parasitic drag increases in proportion to the square of the aircraft speed. At any speed total drag is the sum of the above two components WebI've been writing a series of short aviation articles called "Behind the Drag Curve: Anecdotes from an Aviation Career". The intent is to give a flavour of… 35 comments on LinkedIn The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). Drag may be expressed as actual drag or the … See more The significant aerodynamic properties of aircraft wings are summarised by two dimensionless quantities, the lift and drag coefficients CL and CD. Like other such aerodynamic quantities, they are functions only of the See more For propeller aircraft (including turboprops), maximum range and therefore maximum fuel efficiency is achieved by flying at the speed for maximum … See more • Drag coefficient • Lift coefficient • Angle of attack • Lift (force) See more One example of the way the curve is used in the design process is the calculation of the power required (PR) curve, which plots the power needed for steady, level flight over the operating speed range.
