11induced 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 ),… …
12Rope drag — In rock climbing, rope drag is the friction felt when pulling a rope through a number of pieces of protection, or over rock prominences. It is exacerbated by having great numbers of anchor placements, and especially if they form a zig zag rather… …
13Polymer turbulence drag reduction — In 1948 Toms discovered by experiments that the addition of a small amount of polymer into a turbulent Newtonian solvent (parts per million by weight), whichresults in a Non Newtonian fluid solution, can reduce the skin fictional drag on a… …
14vortex 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 …

17Drop tank — A 330 US gallons (1,200 L) Sargent Fletcher drop tank being moved across the flight deck of an Aircraft carrier In aeronautics, a drop tank (external tank, wing tank, or belly tank) is used to describe auxiliary fuel tanks externally carried …
18Tailless aircraft — A tailless aircraft (often tail less) traditionally has all its horizontal control surfaces on its main wing surface. It has no horizontal stabilizer either tailplane or canard foreplane (nor does it have a second wing in tandem arrangement). A… …

20Falconry training and technique — Training raptors (birds of prey) is a complex undertaking. Books containing hundreds of pages of information and advice by experienced falconers are still rudimentary at best.Many important details vary between individual raptors, species of… …
