The state corporation Rostec reported on Thursday that the PD-8
engine, manufactured entirely in Russia for the
Superjet 100 (SSJ-100) passenger aircraft, successfully completed all its certification tests.
The engine accumulates more than 6,500 hours of operation, of
which 1,449 correspond to flight tests aboard the SSJ-100 and a flying
laboratory; in addition, it passed tests of 150 hours that simulate prolonged operations.
During the tests, the PD-8 demonstrated reliability in
scenarios of freezing, ingestion of birds, water, hail and blade breakage, Rostec said.
The deputy sales director of the United Motor Corporation,
Fyodor Mironov, specified that the results of the engine tests will be
sent to the Federal Air Transport Agency (Rosaviatsia). The review and
possible delivery of the type certificate by this body will be key
steps for the full certification of the SSJ-100 aircraft.
The PD-8 is a dual-circuit turbofan engine with a thrust of
approximately 8 tons, which incorporates 25 critical technologies, 17 of them completely new.
According to Rostec, its turbine blades, made
of materials resistant to high temperatures, stand out, as well as an advanced cooling system
, which guarantees optimal performance in extreme conditions.
