Engine manufacturer Turbomeca is revamping its Tech 600 and Tech 800 demonstrators to enhance fuel efficiency in the 500- to 1,000-shp power category and increase power density in the 1,000- to 1,500-shp bracket, respectively. The goal of Techsys, a third demonstrator, is to resduce Fadec costs by 20 percent through simplification.

The Tech 600 program targets a 15-percent cut in fuel burn at cruise. It will last until 2012. Tech 800, set to end around 2015, targets takeoff power through increased turbine inlet temperatures. “Single-crystal technology is plateauing so we are developing turbine blade cooling,” Charles Claveau, Turbomeca’s head of program and market strategy, said. “The challenge here is in the blades’ small size. Further progress in twin-centrifugal compressors is being sought, too.”
