After receiving the certificate, flight tests of the engine will begin
Deputy Minister of Industry and Trade of Russia Oleg Bocharov noted a very interesting statement made at a meeting on the development of the aviation industry: according to him, a certificate for the PD-8 engine for the domestic SSJ New aircraft will be issued this year, although it was previously assumed that certification PD-8 will take place only at the end of 2024.
The PD-8 engine for the SSJ New aircraft will be certified in September
“ The PD-8 engine should receive a certificate in September and begin certification tests as part of an aircraft. It was a very stressful decision. Now we have shifted [the deadline] almost 16 months to the left,” Bocharov said.
Together with the PD-8, SSJ New will receive several other imported systems and components, the aircraft should become more comfortable. The commissioning of two SSJ New with PD-8 engines should take place before the end of this year.
The PD-8 is a high-thrust turbofan engine developed by Aviadvigatel of Russia. It is a derated version of the PD-14 engine, which is being developed for the Irkut MC-21 airliner. The PD-8 is intended to replace the SaM-146 engine on the Sukhoi Superjet 100 (SSJ100) regional jet.
The PD-8 has a thrust rating of 78 kN (17,500 lbf). It is a two-shaft engine with a single-stage fan, a 14-stage compressor, and a single-stage turbine. The engine is equipped with a full authority digital engine control (FADEC) system.
The PD-8 has been undergoing ground testing since 2021. It made its first flight on an Ilyushin Il-76LL aircraft in December 2022. Flight testing is ongoing, and the engine is expected to be certified in 2023.
The PD-8 is a significant development for the Russian aviation industry. It is the first domestically produced engine to be certified for use on a commercial airliner in Russia. The engine is also expected to help reduce Russia’s dependence on imported aircraft engines.
Here are some of the key features of the PD-8 engine:
- Two-shaft design with single-stage fan, 14-stage compressor, and single-stage turbine
- FADEC system
- Thrust rating of 78 kN (17,500 lb)
- Designed to replace the SaM-146 engine on the Sukhoi Superjet 100
- Currently undergoing flight testing
- Expected to be certified in 2023
