Import-substituting MS-21-310 aircraft with Russian PD-14 engines made its 100th flight

The 100th flight of the MS-21-310 medium-haul airliner with domestic PD-14 engines took place in Zhukovsky near Moscow. Tests are being carried out to obtain the main change in the type design of the aircraft – “replacement of P&W1400 engines with PD-14 engines on the MS-21 aircraft.”

At the first stage of the test, board 73055 is being tested, for which the United Engine Corporation (part of Rostec) supplied a set of five engines to PJSC Irkut Corporation.

About 240 flights are planned in the certification program, designed for two aircraft. The 100th flight of the MS-21 airliner with a domestically produced PD-14 engine under the wing was successful, the certification program is proceeding according to plan. I am sure that the MS-21 will become a worthy replacement for foreign aircraft and that both carriers and pilots, as well as passengers, will like the machine.”, said Vladimir Artyakov, First Deputy General Director of Rostec.

The PD-14 is being tested in conjunction with aircraft systems: the hydraulic system, the electrical system and the integrated air conditioning system. The joint operation of the “aircraft-engine” in various modes is checked. The situations of turning off one of the engines in flight, landing with one engine, engine failure on takeoff (“extended takeoff”), climb gradients during takeoff and descent from different heights with one engine running are worked out. All test programs are related to the confirmation of the flight characteristics of the MS-21 with PD-14 engines.

Flight tests of PD-14 this is a key stage on the way to certification of a liner with a Russian power plant, an opportunity to jointly work out in practice the optimal modes of engine operation. During the tests, my colleagues from UEC-PM and I will continue to improve the weight and resource indicators, as well as the fuel efficiency of the PD-14“, – said Konstantin Popovich, Deputy General Director of Irkut Corporation for the development of aviation equipment – Chief Designer of MS-21.

In the near future, specialists will begin testing another MS-21-310 with domestic engines (tail number 73051).

The lead developer of the PD-14 is JSC UEC-Aviadvigatel, the lead manufacturer is JSC UEC-PM. PD-14 is the first turbofan engine for civil aviation, created in modern Russia. Engine thrust in takeoff mode – 14 tf, dry weight – 2870 kg, fan diameter – 1900 mm. The first flight of MS-21-310 with PD-14 took place on December 15, 2020.
