Embodiment Construction

[0040] Figure 1A , Figure 1B and Figure 1C are simplified diagrams showing a single-row cross-flow water turbine engine, a perspective view of a stage of the turbine engine, and a partial cutaway view of a stage of the turbine engine, respectively. These views are simplified in particular in that they do not show components for attaching or connecting the turbine engine. The turbine engine 1 consists of a set of stages 3 , each stage comprising a cross-flow turbine 5 and a generator 7 . For example, each basic turbine is of the type described in patent application 04 / 50209 (B6412) and is firmly attached to a shaft 8 which is rotatably fitted between an upper flange 9 and a lower flange 10, the upper The flange 9 and the lower flange 10 are connected by a rod 11 . The shafts of the individual turbine-generator stages are independent of each other. Each shaft 8 drives a rotor 12 of a generator 7 , which rotates inside a stator 13 , which provides an electrical supply via ...

Abstract

The invention relates to a turbomachine comprising a stack of stages each of which comprises a transverse-flow turbine and a generator, in which machine each turbine-generator stage has an independent shaft, and in which each stage is associated with an independent fairing (31-32) that orients it with respect to a current, each fairing being of the diffuser type, with symmetric profiled vanes.

Description

technical field [0001] The invention relates to a cross-flow water turbine engine composed of at least one row of stacked turbines. Background technique [0002] The inventors have filed a set of applications for cross-flow hydro turbine engines in which: [0003] - French patent application 04 / 50209 (B6412) filed on February 4, 2004, which relates to a cross-flow hydraulic turbine engine comprising a row of turbines, each turbine comprising blades in the form of V-shaped airfoils; [0004] - French patent application 05 / 50420 (B6869) filed on February 14, 2005, concerning a support structure for stabilizing and avoiding deformation of a turbine train; and [0005] - Patent application PCT / FR2008 / 051917 (B8450) filed on October 23, 2008, which relates to a turbine engine consisting of two double-row assemblies rotating in opposite directions. [0006] These patent applications, which are hereby considered known, describe turbine engines consisting of at least one row of st...
