Production and repair techniques
Engines are high-tech products that call for innovative production techniques. For this reason, MTU is continuously working to develop not only new production processes but also new inspection and measurement methods. Among the most important high-tech processes are laser caving to produce cooling air holes in high-pressure turbine airfoils, as well as adaptive milling, friction welding and precise electrochemical machining (PECM). At its facility in Munich, MTU operates one of the world’s most advanced blisk manufacturing facilities for compressor rotors with integrated disks and blades.
Additive manufacturing methods are gaining in importance. Sometimes also referred to as industrial 3D printing, such processes can be used to produce even complex components, in most cases without the need for conventional tools. This reduces production times and makes components lighter while adding to their functionality. MTU is already using additive processes to produce borescope bosses on an industrial scale for the GTF engine powering the A320neo.
