Going against the common practice of replacing rather than repairing, MTU Aero Engines has teamed with General Electric to make repairs more cost effective for the operator. “It is common for maintenance facilities to use new parts to replace worn or damaged ones, but we prefer to repair. Our technicians can restore even heavily worn components to as-good-as-new condition,” said Dr.

German-based engine manufacturer MTU Aero Engines is here at the Paris Air Show (Hall 2 Stand AB 151) exhibiting a cutaway mockup of a geared turbofan. This is the basic concept for its Claire (clean air engine) technology program, whose aim is to cut carbon dioxide (CO2) emissions by 30 percent by 2035. It is making its first step under the umbrella of the European Commission’s Clean Sky joint technology initiative.
