Embodiments relate to a gas turbine blade for an aircraft engine, the gas turbine blade having a flow leading edge, a flow trailing edge, a suction side, and a pressure side, where the suction side and pressure side extend from the flow leading edge to the flow trailing edge, wherein the gas turbine blade has a damping layer on the flow leading edge and the damping layer comprising at least one matrix material and particles held in position by this matrix material. Further embodiments relate to a method of coating a gas turbine blade and a gas turbine incorporating a plurality of gas turbine blades in accordance with embodiments of the invention.

Gas turbine blade for an aircraft engine and method for coating a gas turbine blade

Method for repairing a gas turbine component, which at least at the spot to be repaired consists of a ceramic composite material, where an energy beam locally heats the gas turbine component in a zone, and where one or more auxiliary materials and optionally fibers and/or particles are fed to this zone, wherein a ceramic is generated in the melting zone through the one or more auxiliary materials, and, optionally, the one or more auxiliary materials together with the fibers and/or particles forms a ceramic composite material.

Method and apparatus for repairing gas turbine components made of ceramic composite materials

Device () for recontouring a gas turbine blade (), comprising:

Device for recontouring a gas turbine blade

A method for recontouring a blade of a gas turbine includes systematically melting a portion of a leading edge of the blade using an energy beam so as to form a new contour of hardened material substantially without incorporating additional material.

Method for recontouring a compressor blade or a turbine blade for a gas turbine

A device for recontouring a gas turbine blade includes at least one support configured to rest on an edge of the gas turbine blade during the recontouring, at least one side bearing configured to rest on an intake side or an outlet side of the gas turbine blade during the recontouring and a machining unit for machining the gas turbine blade. The machining unit is configured to fuse at least one partial area of the edge of the gas turbine blade using a beam of energy that is targeted such that material of the blade solidifies into a new contour, substantially without the addition of supplementary material.
