Reynolds number (Aviation)Reynolds Numbers
REYNOLDS NUMBER  In fluid mechanics, a number that indicates whether the flow of a fluid (liquid or gas) is absolutely steady (in streamlined, or laminar flow) or on the average steady with small, unsteady changes (in turbulent flow; ... Reynolds Number: A nondimensional ratio expressing conditions for similar motions in viscous fluids such as air. Comparisons of Reynolds Numbers permits comparison of wind tunnel results for small models with fullscale practice. Reynolds number: definition, 18.3.2 The Reynolds number of wing sections is reduced, increasing parasite drag and reducing maximum lift capability. Similarity Parameters ..Interactive** A model aircraft is a small unmanned type made to fly for fun, for static display, for aerodynamic research (cf Reynolds number) or for other purposes. A scale model is a replica of some larger design. development of everything from the twoseat Legacy to the Columbia 300/350 (back when the companies were combinedthe airplane is now known as the Cessna Corvalis). Cole is considered especially adept at designing airfoils with low Reynolds numbers ... See also: Aircraft, Wing, Weight, Speed, Drag © MiMi
