SEGELSCHIFF MIT EINEM AERODYNAMISCHEN PROFIL UND EINEM SYSTEM ZUR BESTIMMUNG DER EIGENSCHAFTEN DES LUFTSTROMS, DER AUF EINE VORDERKANTE DES AERODYNAMISCHEN PROFILS TRIFFT

摘要

In order to accurately determine the position of the stagnation point in different zones along the leading edge of a sail of a sailboat, a system comprises series (S1-S5) of pressure sensors (16) distributed from and other of the leading edge (14) and virtually forming patterns (M1-M5) spaced from each other in the form of simple polygonal lines, and a computer (20) connected to the pressure sensors. The calculator determines, along each of the patterns, a respective stagnation point position, defined by a curvilinear abscissa (a1-a5) for which a pressure P * interpolated from pressure measurements provided by the pressure sensors of the corresponding series is maximum, and by an altitude (z1-z5), evaluated from respective altitude data of the pressure sensors of the corresponding series determined from positions of the pressure sensors and the orientation of the sailboat.
