As the Rostec State Corporation reported on December 26, 2022, JSC United Engine Corporation (UEC), which is part of it, began flight tests of the PD-8 power plant designed for the SSJ NEW short-haul passenger liner and the Be-200 amphibious aircraft installed at the Il-76LL flying laboratory owned by the M.M. Gromov LII JSC "United Aircraft Corporation" (UAC). The main operational data are recorded - rotation speed, pressure, temperature, as well as additional parameters necessary to confirm the design decisions taken and ensure the safety of operation of the power plant.
The aircraft is an IL-76LL flying laboratory (registration number "76529", factory number 073410308, serial number 08-07) with a prototype of a promising PD-8 engine installed for flight tests. Zhukovsky, 26.12.2022 (c) Marina Lystseva / JSC "United Aircraft Corporation" From the bmpd side, we point out that judging by the published photos, flight tests of a prototype of a promising dual-circuit turbojet engine PD-8 have been started at the M.M. Gromov Research Institute in Zhukovsky on an Il-76LL flying laboratory aircraft with registration number "76529".
This aircraft (factory number 073410308, serial number 08-07) was originally built in 1977 for the Iraqi Air Force as a military transport aircraft IL-76 of the first modification, in 1989 it was returned to the USSR and converted into a flying laboratory IL-76LL4 (registration number first USSR-76529, then RA-76529) for testing new engines installed under the wing in place of one of the standard D-30KP engines. In 1989-1990, it was used for testing the D-236T turbofan engine, and in 1990-1994 - for testing the D-27 turbofan engine. After that, the board was stored in Zhukovsky for 20 years. After repairs since November 2015, the IL-76LL was used for flight tests of the PD-14 engine.
The creation of a promising PD-8 engine with a take-off thrust in the basic version of 7900 kg is being carried out by the UEC with the head role of JSC UEC-Aviadvigatel (Perm). The PD-8 engine is being created for a new maximally "import-substituted" modification of the SSJ100 regional aircraft, called SSJ NEW. It is also possible to replace the PD-8 engine with the engines of the D-436 family of Zaporozhye production, in particular, on the Be-200 amphibious aircraft. In the future, based on the PD-8, it is possible to create a whole line of engines, including a powerful PD-8V helicopter engine.
Tests of the PD-8 engine gas generator were started in 2021, and bench tests of the first prototype of the PD-8 engine were started in early 2022. At the end of October 2022, Deputy General Director - General Designer of the UEC Yuri Shmotin said that bench tests of three PD-8 prototypes were already underway. Certification of the PD-8 engine by Rosaviation is very optimistically planned for 2023.
