Russia Tests Demonstrator For PD-35 Turbofan

摘要

Russia?s United Engine Corporation (UEC) has made a vital step in the development of the PD-35, its largest turbofan engine. The engine-maker?s Perm-based subsidiary UEC-Aviadvigatel reported in late July that bench tests of a fan demonstrator for the new engine had begun on June 27. UEC-Aviadvigatel managing director and chief designer Alexander Inozemtsev explained the company had to make a scaled-down fan demonstrator as the development of PD-35 is at the design stage now. The new fan is being tested on the company?s smaller turbofan, PD-14, which has been developed for Russia?s new MC-21 narrowbody commercial airliner.
