• 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

• Lift-to-drag ratio — In aerodynamics, the lift to drag ratio, or L/D ratio ( ell over dee in the US, ell dee in the UK), is the amount of lift generated by a wing or vehicle, divided by the drag it creates by moving through the air. A higher or more favorable L/D… …   Wikipedia

• induced drag — That part of total drag caused by the same aerodynamic factors that produce lift. Total drag is the sum of the parasite drag and the induced drag. Induced drag is dependent on the airfoil shape, its lift coefficient (CL 2 ), velocity (1/V2 ),… …   Aviation dictionary

• 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

• 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

• Zero-lift drag coefficient — In aerodynamics, the zero lift drag coefficient CD,0 is a dimensionless parameter which relates an aircraft s zero lift drag force to its size, speed, and flying altitude. Mathematically, zero lift drag coefficient is defined as CD,0 = CD − CD,i …   Wikipedia
