    摘要: A rotor blade particularly adapted for turbine engines includes various injection holes on the blade tip and near the blade tip and on the root plane and near the root plane so directed as to reduce the tip leakage flow crossing the tip and to control the boundary layer by means of fluid curtain and entrainment effects.

    摘要: The invention concerns a method for determining the deformability of the surface of a test specimen. Firstly, by scanning along a line on the surface with a lightly loaded stylus, the surface texture of the specimen is measured. Secondly, the same line is traversed with a loaded indenter such that the surface of the specimen is penetrated. Finally, the same line is traversed again with a lightly loaded stylus to record the new surface texture.
