Engines PD on the basis of a unified gas generator – a family of domestic twin-turbojet twin-engine engines intended for short- and medium-range aircraft and industrial gas turbines.
Main feature PD engine families – the use of a unified compact gas generator.
Key key technologies: hollow wide chord titanium blades, monowheels (blisks) and a welded section in the rotor of a high-pressure compressor, low-emission intermetallic alloy combustion chamber, single-crystal blades of a high-pressure turbine with a promising cooling system, ceramic coatings on hot parts, hollow blades of a low-pressure turbine, composite nacelle.

Engine modifications currently under development
The family of promising turbofan engines for BSMS consists of engines PD-14, PD-14A, PD-14M, PD-10;
PD-14 – basic TRDD for aircraft MS-21-300;
PD-14A – throttled version of the turbofan engine for aircraft MS-21-200;
PD-14M – forced version of turbofan engines for aircraft MS-21-400;
PD-10 is a variant with a reduced pressure of up to 10. 11 ts for SSJ ‑ NG aircraft.
Main parameters of engines (all parameters are given without taking into account losses in the air intake and without air bleed and power for aircraft needs)
Thrust on takeoff mode (H = 0; M = 0), tf
Specific fuel consumption in cruising mode, kg / kgf · h
-(10-15)% of the level of modern engines of a similar class of thrust and purpose
Fan diameter, mm
Dry engine weight, kg
Also, on the basis of the technologies developed in the framework of the PD-14 Project, it is planned to create industrial gas turbines for the production of gas compressor units and gas turbine power plants in the 8, 16 MW capacity classes.
Competitive advantages in terms of economic efficiency of operation are provided with the following main parametric and design features in comparison with competing analogues:
Lower temperatures at the exit from the combustion chamber are the most important factor in reducing cost, reducing risks in achieving the stated indicators of durability and reliability of aircraft engines with a short flight cycle.
Smaller fan diameter PD-14 allows you to have an objective weight reduction engine and frontal resistance engine nacelle.
The optimal size of the internal circuit (gas generator) facilitate the solution of the problem of relatively large air intake from the compressor for various needs and reduce the installation loss of thrust.
Enough high rated fan compression ratio (due to the use of a slightly lower bypass ratio) eliminates the need to use an adjustable outer contour nozzle with an inevitable increase in mass and resistance of the propulsion system and reduces installation thrust losses.
Field-proven gearless circuit PD-14 engine allows to achieve the required indicators of mass, resource, reliability and cost of maintenance.
The optimal combination of moderately high cycle parameters and a proven engine circuit with a direct drive fan helps to reduce the engine price, maintenance and repair costs, weight and drag of the propulsion system and ensure the advantage of the PD-14 engine in terms of economic efficiency of operation and life cycle cost.
