PD-14 engine
PD Engines based
on the common core make a family of Russian bypass two-shaft turbojet engines
with an efficient noise suppression system intended for short- and medium-haul
aircraft and IGTs.
The main specific feature of
the PD engine family is the use of a compact common core and a relatively light
shroudless fan.
Key technologies:
hollow wide-chord titanium blades, blisks and a weld section in the HP
compressor rotor, low emission combustor made of intermetallic alloy, single
crystal HP turbine blades with an advanced cooling system, ceramic coating on
the hot section components, hollow LP turbine blades, nacelle made of composite
materials.
Engine Modifications under Development
- The
family of advanced turbofan engines for short- and medium-haul aircraft
comprises the following engines: PD-14, PD-14А, PD-14М, PD-10;
- PD-14
– baseline engine for МС-21-300 aircraft;
- PD-14А
– derated modification of the engine for МС-21-200 aircraft;
- PD-14М
– uprated modification of the engine for МС-21-400 aircraft;
- PD-10
– derated modification of the engine (10...11 ton-force) for SSJ‑NG
aircraft.
Competitive Advantages by Operational Cost Efficiency
are achieved through the following specific performance-
and design-related features compared to competitors:
- Lower
combustor exit temperature is a very
important factor contributing to cost and risk reduction in reaching the
target durability and reliability of the short-cycle A/C engines.
- Smaller
fan diameter of the PD-14 engine contributes to
real engine weight and nacelle drag reduction.
- Optimum
dimensions of the core duct help resolving
the problem of relatively high compressor air bleeds for different
purposes and reduce installation thrust losses.
- High
enough fan design pressure ratio (due to somewhat
lower bypass ratio) eliminates the need in the variable fun duct nozzle
which inevitably increases engine weight and drag, and reduces
installation thrust losses.
- Conventional
configuration of the PD-14 engine without a
gearbox which has been well proven in service enables achieving the target
weight, life, reliability and maintenance costs.
Optimum combination of reasonably high cycle parameters
and a well proven engine configuration with a direct fan drive provides for
lower engine cost, MRO costs, lower powerplant weight and drag and makes the
PD-14 engine excel in operational cost efficiency and life cycle cost.

Specialists will complete the final certification stage
of flight tests of PD-14 perspective aircraft engine for the new Russian
passenger jet MC-21 by the end of 2017, Managing Director of UEC-Aviadvigatel
company Alexander Inozemtsev told TASS on Monday.
US Pratt & Whitney PW 1400G engines are currently
mounted on the airplane.
"The second stage of flight tests ended in March. We
are now preparing the third stage, already the certification one, which will
enable us to mount engines on MC-21," Inozemtsev said.
The third stage of flight tests will be completed by 2017
year-end and a special statement is planned to be signed after that,
authorizing outfit of aircraft with domestic engines, he added. Source: ruaviation.com
Development of aircraft engine PD-14 follows the plan
according to the information provided by Joint engine manufacturing corporation
(ODK). Russian certificate is to be issued in the second quarter of 2018. One
of the first flying developmental model of the new jet MC-21 will be equipped
with PD-14 engine in 2019.
Alexander Artyukhov, Head of ODK, mentioned that
performance of bench testing and flight testing of MC-21 would require
manufacture of 11 engines PD-14. At the present time there are 10 ready
engines. One more engine will be manufactured in September 2017.
“We suppose that time frames of Russian certificating,
according to the plan, during the second quarter 2018 will be provided, giving
us possibility for carrying out delivery of engines for the start of MC-21 jet
flight and certificate tests by the end of 2018”, - Alexander Artyukhov’s words
