The improvement of the aerodynamics characteristics of aircrafts requires introduction of the new progressive approaches, one of which is the application of an adaptive flexible-skin wing. In a kind of constructive, layout, technological and aerodynamic complexity of such unit using for its development CAD/CAM/CAE of a high level, such as UNIGRAPHICS, CATIA and others, allows conducting a life cycle support of a product. In present clause two basic tasks arising at designing of an adaptive wing are opened. This conducting a designer database of ready external contours using a principle of parametrical designing in CAD/CAM/CAE and mathematical modeling two-dimension contours of flexible coverings for various corners of a deviation of mechanization leading and trailing edges of an adaptive wing.
