Drag freight — A drag freight is a slow, high tonnage railroad train, often carrying commodities such as coal or ore. Compared to Fast freight[disambiguation needed ] trains, drag freight trains have a very low power to weight ratio, making them somewhat… … 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
Aspect ratio (wing) — In aerodynamics, the aspect ratio of a wing is defined as the square of the wing span divided by the wing area.:AR = {b^2 over S}where: b is the wing span, and: S is the wing area.Informally, a high aspect ratio indicates long, narrow wings,… … 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
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
vortex drag — That part of total drag caused by the same aerodynamic factors that produce lift. Vortex drag is dependent on the airfoil shape, its lift coefficient (CL 2), velocity (1/V 2), weight (W 2), and aspect ratio (1/A). Also called induced drag … Aviation dictionary

airplane — /air playn /, n. 1. a heavier than air aircraft kept aloft by the upward thrust exerted by the passing air on its fixed wings and driven by propellers, jet propulsion, etc. 2. any similar heavier than air aircraft, as a glider or helicopter. Also … Universalium
