Measuring device of the wake of a sailing model

摘要

The invention relates to a device for measuring the wake of a navigation model (17) in a test basin (1) equipped with a movable platform (2) capable of being displaced in order to follow the model at the same speed as the latter. This device comprises five heads (3) for the optical spot measurement of the water level, these being carried by the platform (2) and being capable of being displaced horizontally relative to the latter in a direction transverse to the direction of its movement following the model (17), in such a way as to provide, by transverse scanning, a log of the undulations of the water surface (8) attributable to the wake of the model (17) in five juxtaposed parallel vertical planes forming a band (16). …IMAGE…
