Engines are high-tech products that call for innovative manufacturing techniques and repair methods. MTU pursues the full spectrum of activities, ranging from process development and new testing and measuring methods to automation and production and maintenance planning.
Among the most important high-tech manufacturing processes that we use are laser caving to produce cooling air holes in high-pressure turbine airfoils, as well as adaptive milling, friction welding, electrochemical machining (ECM) for turbine disks and precise electrochemical machining (PECM) to manufacture titanium and nickel blisks. MTU is one of the world’s leading manufacturers of these components; in Munich, it operates one of the most advanced, pioneering production facilities for producing compressor rotors this way.
Digitalization is becoming more and more prevalent in production operations: the wealth of data available from processes (smart data) can be used to monitor and control sensitive engine components as an additional mechanism for excellent quality assurance.
Additive processes are also becoming increasingly important: today, we use selective laser melting to manufacture production components for the GTF engine that powers the A320neo, and we are working on gradually expanding the range of components we produce this way.
