Russian aviation: real progress or imitation of success?
Introduction
The recent successful flight of a Superjet aircraft with Russian PD-8 engines was presented in the Russian media as a landmark event in the history of domestic aviation. However, in order to objectively assess the significance of this achievement, it is important to consider it in the context of the general situation in the Russian aviation industry, compare it with international standards and analyze the real pace of development of the aviation industry in Russia.
Why is it important to analyze this event?
Import substitution and the reality of production – Is Russia really capable of independently producing competitive aircraft engines? How much does current achievement reflect real progress?
Comparison with world leaders – What production volumes and technological level do Boeing, Airbus and Chinese COMAC demonstrate? Is Russia lagging behind, and if so, by how much?
Long term prospects – Is Russian aviation capable of entering the world market and reducing dependence on foreign technologies?
This article examines the current state of the Russian aviation industry, analyzes the achievements presented and compares them with global trends.
The Superjet prototype successfully completed its first flight with Russian PD-8 engines in Komsomolsk-on-Amur. The test lasted about 40 minutes, during which the plane reached a speed of 500 km/h and an altitude of 3000 meters. The crew noted the stable operation of the power plant and the completion of the flight mission.
PD-8 is a two-circuit turbofan engine with a thrust of 8 tons, designed for the Superjet and the Be-200 amphibious aircraft. During its development, technologies used earlier in the PD-14 engine were used. Engine certification is expected to be completed this fall.
Previously, Superjets used Russian-French SaM146 engines, which were dependent on foreign suppliers. Development of the PD-8 began in 2019 as part of the import substitution program. According to the plan, completely domestic Superjets with Russian airframes, avionics and engines will go into mass production by 2027.

Stated "facts" from sources:
First flight with Russian PD-8 engines – tests took place in Komsomolsk-on-Amur, the plane was in the air for 40 minutes, reached 500 km/h and an altitude of 3000 m.
Crew composition – Dmitry Demenev, Igor Grevtsev, Maxim Gryukanov.
Engine PD-8 – double-circuit turbofan, 8 tons of thrust, designed for Superjet and Be-200.
Previously used SaM146 engine – Russian-French, with problems in operation and dependence on foreign suppliers.
Development of PD-8 began in 2019 – within the framework of the import substitution program.
Until the end of March 2025 – transfer of two more experimental PD-8 engines for testing.
Certification of PD-8 is expected in the fall of 2025.
Completely imported Superjets – production with Russian components is planned, serial deliveries to airlines from 2027.
40 aircraft are planned to be transferred to airlines.
Should I disassemble next?
Accepted. I'm starting to analyze the algorithm.
1. First flight with Russian PD-8 engines
Veracity check: Confirmed by a statement from Rostec and a number of Russian media.
Reconciliation with precedents from the manufacturer (ODK):
PD-8 is a “light” version of PD-14, but its development was delayed due to technological difficulties.
Previously, UEC experienced problems with engine certification (for example, PD-14, which dragged on for years).
Reconciliation with cases from the customer (Rostec):
Rostec has previously made “high-profile” announcements, for example, with import substitution in MS-21, but the deadlines were constantly shifted.
Reconciliation with cases at the recipient (airline):
Russian air carriers previously experienced difficulties with the SaM146, but purchased Western aircraft en masse (before the sanctions).
So far, no airline has expressed a clear readiness to receive the Superjet from the PD-8.
2. Crew composition
Veracity check: Confirmed by Rostec’s statement, but is not of fundamental importance.
UEC has precedents: Test flights with factory crews are standard practice.
Cases from the customer: Rostec usually does not advertise the names of pilots if the result is questionable.
Cases at the recipient: Airlines care not about the names of the pilots, but about the test results.
3. PD-8 engine – double-circuit turbofan, 8 tons of thrust
Veracity check: Yes, the parameters correspond to official data.
UEC has precedents:
The PD-14 engine for the MS-21 has been developed for 10+ years.
Finalization of the PD-8 could take longer than stated.
Cases from the customer:
Rostec promised 100% localization, but technologies for turbine blades and electronic control remain imported.
Cases at the recipient:
Airlines are waiting for operational tests, not just applications.
Continue further?

The potential to more than double the scope of #Trump’s #tariffs has alarmed economists & some congressional #Republicans, while other WH allies are concerned about the logistical challenges of a complicated new #import #tax regime. The precise nature of these new duties has spurred extensive discussions at the highest levels of the admin, w/VP #JDVance, #Commerce Secy #HowardLutnick, WH aide #PeterNavarro & #Treasury Secy #ScottBessent all playing a role in the talks….

@apolaine @macst @pluralistic watson.ch/wirtschaft/interview Een Zwitsers artikel waarin Christophe Germann pleit voor het beëindigen van de handhaving van intellectueel eigendom van de USA. Dit zou de lobbyisten van de techbro`s er toe kunnen brengen om de oranje aap in het Witte Huis op andere gedachten te brengen wat betreft het heffen van importtarieven.. #import #TarriffWar

Donald Trump terrorisiert die Weltwirtschaft mit seinen Zöllen. Nun hat ein Schweizer Jurist eine Idee, wie man der US-Regierung begegnen könnte.

#politiek #eu #import #tarieven

De EU is van plan om in antwoord op MAGA import tarieven zelf ook import tarieven te heffen.

Persoonlijk vind ik dat niet heel slim. Als één persoon in de sloot springt, waarom spring jij dan zelf in een andere sloot? Import tarieven betekent dat producten en diensten voor onszelf duurder worden.

Ik zie veel meer in het opheffen van zaken waarin wij hebben toegestemd om de oude USA tevreden te stellen. Export van ULV machines naar China. Opheffen copyright etc

#Update

Yesterday I started the #mail #migration using #KMail #import tool and targeting #thunderbird profile folder.

Please note that I use Thunderbird since 15 years as my favorite mail client, and I used to have 5 or 6 accounts (plus my daugthers' accounts for school). So the amount of emails to migrate, even though I'm convinced that only the essential was left, was huge... ~92 GiB!!!

Now... I feel I need to reboot my #Debian, that looks a bit unstable after 1 full day spent crawling and indexing old emails... and then start Kmail... wish me good luck!
