▎ 摘  要

NOVELTY - The shovel (1) has a shovel blade (3) with an extension (E1) in radial alignment regarding a main rotational axis (A) of a fluid-flow machine (7) and another extension formed transverse to the former extension. A blade root (5) is connected to the shovel blade and closes the shovel blade in the former extension, where the shovel is made of monocrystalline graphene. The graphene encloses preformed inner bodies. The graphene is formed in a form of layers of sheet-like graphene structures connected with each other by impregnation and/or fusion and/or bonding. USE - Low pressure shovel for a thermal fluid-flow machine (claimed) e.g. gas turbine, steam turbine and compressor, in an airplane engine. ADVANTAGE - The shovel is made of monocrystalline graphene, thus increasing stability and thrust transmission of the shovel, simultaneously reducing density, weight and cost of the shovel, and manufacturing the shovel in an effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a shovel for a thermal fluid-flow machine. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a shovel. Main rotational axis (A) Extension (E1) Low pressure shovel (1) Shovel blade (3) Blade root (5) Fluid-flow machine (7)
