Today UEC (Russia’s United Engine Corporation) announced they are starting the second phase of the PD-14 engine flight tests. UEC claims the PD-14 is a fifth generation engine being developed for powering the MC-21 airliner. They also claim using up-to-date technologies and materials, including the composites. The PD-14 is the first completely new Russian aeroengine for the civil airliners in a very long time. The test engine is seen here in the flight test aircraft.
UEC has built 11 test engines so far. During 2015-2016 the first stage of the flight tests were successfully performed at the Flight Research Institute at Zhukovsky. The second stage of the flight tests is planned to remove the “limitations regarding the engine’s thrust ratings and with provision for the high altitude engine starts”. The performance of the PD-14 engine will be tested at all speeds, altitudes and thrust ratings.
