Abstract : The HARVEST project's objective consists in developing a new type of turbo- machine, named hydrolien, made of inverse flux turbines. The research conducted in this dissertation deals with the implementation of the stream tube of a hydrodynamic tunnel; it consists in the experimental determination of hydrodynamic performances of models designed for the turbines and, more specifically, of measuring the angular evolution of hydrodynamic efforts on the blades. The efforts were measured through piezoelectric sensors device, along with a regulatory and transformational energy device, by way of synchronous power generator. The elaborations of the design, as well as the different steps of adjustments and characterization of the subsets, are then described. Finally, a series of experiments leads to methodological and technological conclusions concerning the entire project.
