Turbine of thermostructural composite material, in particular a turbine of large diameter, and a method of manufacturing it |
摘要 |
The turbine comprises a plurality of blades disposed around a hub between two end plates, with the blades, the hub, and the end plates being made of thermostructural composite material. The hub is made by stacking plane annular plates of thermostructural composite material along a common axis. Each blade is made individually by shaping a two-dimensional fiber fabric in plate or sheet form to obtain a blade preform, by densifying the preform with a matrix to obtain a blade blank made of thermostructural composite material, and by machining an outline for the densified preform. Each end plate is obtained by making an annular preform by means of a two-dimensional fiber fabric in plate or sheet form, and by densifying the preform with a matrix to obtain a part made of thermostructural composite material. The blades are assembled to the hub between the end plates, with each blade being connected to the hub by a portion forming a blade root.
