The Sam Engine is much older than the PD8 .. there's a possibility that the gear box was intentionally excluded..

PD-8 is twin-spool design so doesn't need a gearbox to run the front fan at diff revs to the hot core. That PW engine you mention on the A-220 is 50% bigger diameter front fan than the PD-8/Sam-146. So it has planetary gears due to issues with the tips of the fan blades speed getting too high. A-220 is an usual spec 5-abreast seating for 200 passengers .... Russia has no aircraft that size so there is no need for a geared PD-8 version.

That Geared TurboFan Engine has bankrupted airlines. My take would be - less complications, more simplicity, better materials and structures, easier maintenance and operability.

oui c'est une erreur

O sea,todos ingenieros tienen que seguir la misma linea de otros,no sean tontos, la belleza de Rusia son sus soluciones tecnicas diferenciadas,no hay nada que ellos no sepan,lo importante es que el motor sea fiable,si consume menos mejor,la configuracion no interessa.

Russia needs a reliable, in service jet, more than it needs a higher efficiency jet on the drawing board. If you look at Leap engines vs GTF, I think it's pretty obvious that the gear box is a long way from perfect.

Si será competitivo ya que tiene un menor consumo de combustible que el francoruso

It will be if it lowers maintenence requirements...

El PD-8 es un Kusnetzov NK-8-4 conbun largo trazo de operacion en el Illushin-IL-62 hace 30 años, modernizado y actualizado con exelente potencia y reliabilidad, simple y con controles digitales, no es un motor nuevo sino una nueva implementacion de los cientos de prototipos de las varias Bureaus de diseño de motores de aviacion, también podrian poner un Soloviev, Klimov, Progress o Motor Sich ya que regresa de nuevo repatriado o pueden hacer una combinacion de los mejores atributos de todos ellos, si no ven oroductos o aplicaciones aeronauticas de nuevos modelos no es porque no tengan sino las casas de diseño continuamente producen prototipos y pruevas de nuevos motores continuamente....

Du temps du Concorde la fibre de carbone n'existait pas... Sur les appareils commerciaux la super croisière n'était pas envisagée. Le Concorde volait bien plus vite,et c'était le but recherché. Cet avion arrive 50 ans plus tard, il reprend exactement le profil d'aile. Je ne vois pas le progrès à part la super croisière. 50 ans plus tard c'était le minimum et pas une révolution

Wait-a-minute-here! From having our Russian assets smashed in Ukraine & Syria? Economy deep sixed? But suddenly we got a world beating TU-214 A/C, better than Airbus and Boeing? Ready 2 sell U one? With over 50 % of the critical parts sourced in the West/US/China and on the black market? Yeah! Russia, the world is just gagging/itching 2 buy 1 or 2!

I dont thing pd-8 has a lot in common with pd-14, it looks more like an evolution of Sam146

Rusia es lenta pero aplastante. No tiene apuros ni busca una carrera espacial propagandística. Trabajan con objetivos claros y precisos sin que les afecte la economía en medio de un gran conflicto bélico con la OTAN. La familia Angará es un nuevo avance en la renovación de sus seguros cohetes portadores. Su meta final es reconquistar la Luna y establecer una base en ella.

So here's the core of it. they made subsonic 1seater out of plastic to test the materials they want to use on a passenger liner... eventually. The rest of the video explains things about Concord and Tu144, both supersonic passenger airliners that actually flew. You're welcome 😂

A two engine IL-96 is essential like a Boeing 777-200.

They could build a launch platform in a shallow part of the North Western Black Sea or build a space base on the Eastern tip of Sebastopol and use a drone ship to catch the boosters in the Eastern Black Sea.

Angara are heavy class rockets and in all major countries their primary purpose is to launch heavy military satellites into GEO orbits - its the same in the USA too ..... 95+ % of launched are the medium Falcon 9 which is roughly the size of the Soyuz rocket. Falcon Heavy launches are very rare. Other uses for heavy rockets are lifting spacestation modules of 20tons to LEO and for deep space missions. All quite rare launches. Interesting the RD-180 is derived from the RD-170 which was used for the boosters of the Buran project and were in fact designed to be used up to 10x so it is not impossible for them to be reusable - the question is why bother with such infrequent launches ? Angara is a military imperative for Russia simple as that

Stretch it to match 757-300

Не смеши нашел великую державу

Excelente, espero mas informes como este 👍🏽

Tu-214 with length 49 meters, are you sure?

Rusia al desintegrar la URSS en forma abrupta, perdió la supremacía en muchos ámbitos, no obstante sus aviones son viables para el uso civil, le falta la escala de producción que perdió con la desintegración abrupta de la Unión Soviética, Putín tal vez es el político mas notable del siglo 21, pero fue uno de los responsables principales de la disolución de la URSS y eso muchos no se lo perdonan, aún que hay que reconocer que en su tránsito violento al capitalismo recupero la tenencia del estado y con ello una economía potente.

Brave Russia! against the philosopy of Imperialism. Don’t sell yourself to their sanctions. Until the evils regret & give up and lift up them by themselves at least for the sake of their benefits. But there is not so much worry since Russia is an independent & industrialized country. Also Mc-21 with foreign engines and compartments is meaningless! It is better that you go ahead with imperialist made planes further than adopting an evil-made engine on your own aircraft which will be too troublesome in the future.

Bravo Rusia, eso se llama soberanía. Saludos desde Argentina.

Russia siempre ha sido pionera en todo lo que toca a la exploracion espacial. 1- primero hombre a ir al espacio, 2-primero satelite espacial, 3-primero pais a enviar un veiculo a la Luna, 4- primero pais a construir una estacion espacial (la Mir) y muchos otros avances en la esfera espacial.

Le TU 214 ? De la même conception que le Concordsky ?

Esperamos por el PD-18 y una autonomia de 9000km para 240 plazas,los avionicos podran ser del MC-21,con dedicacion lo consiguen.

Sin sanciones, con los problemas de Boeing con su serie 737 Max y Airbus con sobre saturaciòn de pedidos, estos TU 214 llenarìan un faltante en producciòn y entregas. Si logra bajar precios operativos generales, y optimizar aviònica y equipos varios en cabina, este modelo Tupolev puede imponerse, pero primero, debe es llenar todo lo que falta cuando los aviones occidentales por esas sanciones, salgan de uno en uno.

The TU-214 is a modern aircraft with flight-by-wiere triplex system and modern PS-90A3 engines in its newer versions, more reliable, powerfull and greater payload and range aircraft.... It can not be compared with a dinosaur like the B-757 with pulleys, cables and hydraulic controls, it is an old aircraft that can be compared only with the DC-8 or the 727's of yesteryears....

Rostec need is on Airline company

Russian sky Dragon.

The Boeing 757 production line ended in 2004. Currently, airlines have started to phaseout this model. And the new benchmark in this segment in terms of economic efficiency is the A321XLR/LR. And it is mandatory to have a cockpit for two people. What is the point of comparing the Tu214 with an obsolete aircraft that is no longer in production??

Ce reportage est de bonne qualité car il dit la vérité sur cet avion, c'est un avion un peu dépassé dont le seul avantage est d'être fabriqué en Russie avec des composants Russes. Pour le reste un A321 fera mieux. Question : Comme c'est un avion soviétique, est ce que le poste de navigateur/ingénieur est toujours d'actualité sûr cet avion ?

the Airbus A321neo is now much the same size as the Tu-214 and 757- around 200 passengers The reason is that airlines can now fly narrow body planes direct over long distances mainly to holiday destinations and the airport there cannot accept heavy wide bodied aircraft. Understandably who wants to fly into a big hub in a big jet then have to transfer to a smaller regional plane to get to your holiday destination ? Which is exactly what Russia's subsidising of regional routes is meant to achieve - allowing people living in smaller cities a better standard of living by not having to fly to major hubs to get anywhere. The idea of course is to encourage population growth in smaller cities - or stop the decline of populations there. Particularly in the East. Same reason the SSJ-100 has quite a long range for a regional jet.

Tu 95 pourrait rester actif pendant. Des décennies vue que il pourrait porter dans ces soutes des missiles hypersonique comme par exemple le kinjal à tête thermonucléaire qui donnera des sueurs. Froides

No American has not operated B-757-200 for long time, Delta seems to operate the aircraft on certain similar like routes ( MIA - ATL)

😂 toujours la Russie en avant

Yes!

Saya pikir ada yang salah. Tu-204 dan Tu-214 panjangnya sekitar 46 meter, bukan 49 meter.

Los problemas eran todos de los motores feanceses

Boeing 737 has became the flying coffin 🪽 ⚰️ !!! It will be safer to fly on these rather than b-737s !! 😂😂😂😂😂😂😂

Ржали даже китайцы с этой поделки из г.. и палок. НЕТ палки уже кончились

russians are on another level. all of them are alpha as fuck.

Si no son reutilizables pues ya son obsoletos sin haber comenzado, los cohetes de spacex son más grandes con mayor capacidad y reutilizables así que no se pueden ni de lejos comparar

C919 podra sofrir de los mismos planes diabolicos de ocidente com Rusia en el caso del SSJ100, hecerlo entrar en mercado con componentes extranjeros y despues sancionar para que detenga su reputacion,se retraso el MC21 pero quando esté operacional sera unico en su condicion,el C919 quienes lo compren dependeran de la buena volunta de las politicas del país de los provedores.

Why aren't the Russians making progress on returnable rockets?

Only reusable rockets will economically have any chance of success in the commercial payload market.
