Abstract
A device for measuring the wake of a sailing model in a trail tank is equiped with a platform capable of pursuing the model in the same direction and at the same speed as the model. The device includes five optical point measurement heads, carried on the platform and capable of moving horizontally with respect to the platform and crosswise with respect to the direction of pursuit of the model, thereby scanning the wake transversely and measuring the water surface undulation due to the model wake, in five adjacent vertical parallel planes forming a strip.
Claims8
Device for measuring the wake of a model sailing in a trial tank equipped with a moving platform capable of pursuing the model in the same direction and at the same speed as the model, wherein said measuring device includes at least one optical measuring head measuring the water level corresponding to at least one local point and being carried by the platform and capable of moving horizontally with respect to said platform in a transverse direction with respect to the direction of its motion of pursuit of the model, in such a way as to provide by transverse scanning a measurement of the undulations of the water surface due to the wake of the model in a vertical plane parallel to said transverse direction.
