INTERSECTION OF AIRPLANE COMPONENT SURFACES FOR DESIGN OF AN AERODYNAMIC CONFIGURATION
Краткое описание
Numerical evaluation of an intersection curve of parametrically defined surfaces of different-purpose aircraft components is considered. Two methods complementing each other in practical use are presented. Iterative algorithms to search a point on an intersection curve are described in detail. Parametric singularities that require special handling during the iterations are analyzed. Methods are given to proceed with convergence to a curve point in the presence of singular points of various order, and to evaluate length and direction of a linearized step along the curve to serve as an initial guess for iteration toward the next curve point. The presented methods have been implemented in a CAD/CAM software system.
