JIG FOR MEASURING LIFT FORCE IN UNDER THE SEA OF SAIL YACHT

摘要

The present invention relates to a jig for the underwater lift force-oriented measurement of a sail yacht. The jig includes a base plate placed on a floor surface of a yacht; a pair of support blocks installed on an upper surface of the base plate, and placed in parallel with each other; a control shaft installed to rotate by penetrating the support blocks; a connection rod placed between the support blocks, and fixed on the control shaft; and a component force system fixing plate fixed on an upper part of the connection rod, and having a 6 component force system installed. According to the present invention, as an action center point of a keel and the center of inertia are easily and conveniently found and matched, the straightening force of the yacht is secured.
