LEK94 - MTU Aero Engines develops new material
Munich – Light in weight, heat-resistant and affordable: for use in low-pressure and intermediate-pressure turbines, MTU Aero Engines has succeeded in developing LEK94, a material that is setting new benchmarks. "A material of this type was still missing in the current offerings of high-temperature materials. There're lots of pricey and heavy high-end materials around, but with their overwhelming temperature and strength capabilities they tend to be overgunned in some of the applications," explains Dr. Jörg Esslinger, who supervises materials engineering at MTU. The new lightweight has promptly found a prominent home in the low-pressure turbine of the GP7000 powering the Airbus A380.
