A nozzle guide vane seen after fluoride-ion cleaning [note that the fracture would disqualify the actual blade for re-use in an engine - this is a sample shown for demonstration purposes]<br>
This is one of ten blade samples showcasing the repair process developed by MTU engines to send damaged blades back into service. The blades were on display at the Paris Air Show 2013; they are high-pressure internally-cooled turbine nozzle guide vanes on the V2500 engine.
