    摘要: Turbine and compressor casing abradable component embodiments for turbine engines, with nested loop pattern abradable surface ridges and grooves. The nested loops comprise nested fully closed loops or a spiraling maze pattern loop. Some embodiments include distinct forward upstream and aft downstream composite multi orientation groove and vertically projecting ridges planform patterns, to reduce, redirect and/or block blade tip airflow leakage downstream into the grooves rather than from turbine blade airfoil high to low pressure sides. Ridge or rib embodiments have first lower and second upper wear zones. The lower zone optimizes engine airflow characteristics while the upper zone is optimized to minimize blade tip gap and wear by being more easily abradable than the lower zone.

    摘要: A blade arrangement with a rotor and a plurality of blades which are arranged on the periphery of the rotor in a ring and a plurality of damping elements are provided. Between two directly adjacent blades at least two damping elements are arranged in series in the circumferential direction of the rotor. As a result of a centrifugal force, which acts in the radial direction, during a rotation of the rotor around a rotor axis adjacent damping elements come into contact with each other, and one of the two damping elements comes into contact with one of the two blades and the other of the two damping elements comes into contact with the other of the two blades.

    摘要: With a gas-turbine engine, a sealing and damping element (9), which is loosely held between two adjacent platforms (6a, 6b) of turbine blades attached to a rotor disk, generally has a cross-section in the form of a straight three sided prism corresponding to an equilateral triangle, however with convex rubbing surface sides. Due to small swiveling movements enabled by the curvature of the sides, an increased rubbing and wear area is created during operation, which is adapted to the blade geometry and can be determined in advance, thus increasing damping and sealing efficiency.

    摘要: A method for repairing or replacing a mechanically retained vane is provided. The method comprises the steps of forming an oversized cavity in an outer base, inserting a flared end of a vane in the oversized cavity, and inserting a wedge for mechanically retaining the flared end of the vane in the oversized cavity. The wedge has a first surface with a constant pitch angle to match the outer base cavity and a second surface with a variable pitch angle to match the vane tip dovetail.
