The Tech 800 core engine demonstrator made its first run last month at Turbomeca’s Bordes, France headquarters, the company announced last week. A high-pressure spool for the 1,100-shp engine class, the Tech 800 is a precursor to the engine manufacturer’s TM800 Arrano. The Arrano turboshaft will power the Eurocopter X4 medium twin, a Dauphin successor planned for 2017.
