Goodrich is moving the technology of dual-channel full-authority digital engine controls (Fadec) into smaller and smaller turboshaft engines. At Heli-Expo’09, the company (Booth No. 3241) is showing dual-channel Fadec systems like the unit installed on the 1,050-shp Pratt & Whitney Canada PW210S that powers Sikorsky’s new S-76D, which made its first flight on February 7. “This is the first dual-channel control on a turboshaft engine,” said Tony Gentile, Goodrich vice president of marketing and programs.
The company certified a dual-channel Fadec on Honeywell’s HTS900, which had been slated to power Bell’s canceled 417 and the Army ARH. The HTS900 Fadec received FAA certification last December. It is also developing dual-channel Fadecs for Turbomeca’s Ardiden, Arriel and Arrius engines, according to Gentile. The 1,000-shp power level is where most dual-channel Fadec development is taking place, he added.
