In July 2011 the third milestone in the ‘Engines for the MS-21’ Project was successfully negotiated; the project is being implemented within the frameworks of the program aimed at creation of a family of engines based on a standardized gas generator.

The project objective is to create the basic PD-14 engine with 14 tons of thrust, and variations designed for operation in the upcoming MS-21 family of aircraft and upcoming multi-functional transport planes.

The developer spearheading the project is Aviadvigatel, OJSC, and the main producer is Perm Engine Company, OJSC.

The third milestone is the most important stage in the project implementation phase, as it is introduced to determine the configuration of the engine being developed, assess its competitiveness, and make decisions whether continuing of working on the Project is expedient.

It took one year to get from stage two to stage three. During this short period of time the chief developer and other project participants have accomplished a huge amount of work:

The Third Milestone Committee worked using the conclusions made by the expert groups, consisting of the leading experts from United Aircraft Corporation, the State Scientific Research Institute of Civil Aviation (FGUP GosNII GA), Irkut, Sukhoi Civil Aircraft, Research Institute of Aviation Industry Economy, Central Institute of Aviation Motors (CIAM), “VIAM” FSUE (RF SRC), OAO “United engine corporation managing company”, NPP Motor, UMPO, Saturn, FSUE “GTERPC “SALUT”, OJSC Aviadvigatel, OJSC Perm Engine Company, and others.

The Committee’s final minutes states, that:

At present, the prototype gas generator is ready for the second round of testing, as well as for testing with pressurized and heated air in the gas generator’s intake. The high-pressure turbines are being assembled for testing at the TS-2 stand at CIAM.

All works on the ‘Engines for the MS-21’ project are being performed according to the stated schedule, which guarantees creation of the engine according to the timetable agreed upon by UAC and UEC to create the MS-21 aircraft and engines for them.

Aviadvigatel, as the main developer, is carrying out the R&D involving corporations and leading engine-building NIIs, and bears responsibility for meeting of the engine development deadlines, compliance of the design documentation with SOW and for ensuring that the design of the engine conforms to airworthiness standards and other standards throughout the entire engine life.

According to Igor Maksimov, Deputy General Designer and Chief Designer of the PD engines, the approval of the draft design of the advanced engines allows the Aviadvigatel specialists and those from other enterprises participating in this project to get started on the technical design phase of the basic PD-14 engine. “At present we have developed the basic working design documentation and have begun preparing the drives and systems for the technology demonstration prototype engine, which we are planning to present to the clients in 2012,” said Maksimov.

A 1:4 scale model of the PD-14 was unveiled for the first time at MAKS-2011, this August.


Implementation of the ‘Engines for the MS-21’ project, within the framework of the Federal program ‘Development of Russian State Aviation Technology in 2012-1010 and up to 2015’ will allow successful accomplishment of the following tasks:

OJSC Aviadvigatel is the leading Russian design bureau for development of gas turbine engines for aviation and industrial applications. It is part of the United Engine Corporation, a wholly-owned specialized subsidiary of OPK “OBORONPROM” for engine-building assets management.

OJSC OPK “OBORONPROM” is a diversified machine-building group founded in 2002. It is part of the Russian Technologies State Corporation. Its primary business lines are helicopter-building (Russian Helicopters, JSC), engine-building (MC “UEC”), and other assets.
