The A330 is a bad comparison, it first flew in 1992 & came with FBW control back then. The YAK 42 first flew in 1975.

No it is not! The A330 is really a modern derivative of the A300 which had its first flight in 1972! The A330 simply added modern engines, super critical aerofoil wings, wing tip devices, FBW and modern glass cockpit. Of course, a modernized interior was also necessary.

In reality, ......that is no more than I am doing with the YAK-42.

The A330 uses the same fuselage cross section as the A300, basically everything else is new.

As far as a modernised YAK 42 goes, the days of the tri jets are dead unfortunately.

Going by your logic, the Boeing 737NG is all new since, just like you said, Boeing claims everything is 'all new' too!

The point you miss about my argument is that these 'all new' technologies are based on and piggy backed on proven (older) and existing concepts. The A330 is exactly what I described above - An A300 with new wings, newer engines, avionics and interior upgrades! This is why when Airbus tried to sell off the same concept for an A330 replacement (by simply upgrading once again), the proposal was flat out rejected by the market. The A350 is the first truly new Aircraft that has come from Airbus since the A320! This is why the A350 is called 'the Aircraft that Airbus did not want to build'!

Where did I say that? I know the 737NG is definitely NOT all new.

Look, it's cool to have fantasies about planes but honestly a modernised YAK 42 could never compete with what's on the market today. For a start, it has 3 engines. Even if the Ivchenko-Progress D-436 turbofans are as efficient as you claim, there are 3 of them. A whole extra engine & it's systems to maintain. Plus who would look after the after sales support?

I love your enthusiasm & I think old soviet aircraft are great but something like this would just never happen.

Your opinion, not mine. No one can argue with an opinion!

The business case was not for an all out competition - that is an impossibility with this concept - After all, only 180 YAK-42s were ever made! If you read the initial comment, the business case is for a limited run, 50-60 units at best. The business case is for a specialized aircraft that fulfills a small but crucially neglected niche. There are a lot of nations and airlines all over the world that would welcome a modern alternative to an A320 or a B737. Just off my head; Cuba, Iran, Venezuela, Bolivia, Burma, Syria, Laos, many African nations and south American nations.

It is the same reason why Fokker F100s are still in demand. Iran probably has over 20 in operation. It is the same reason why Sukhoi SSJ100 is being sold in southeast Asia as we speak. It is the same reason why Cubana is taking delivery of (3) An-158s this year and has placed an order for 3 units of Ilyushin IL96-400s. Even though in truth, none of these aircrafts can really do what an A320 or B737 can (being much smaller or bigger). This leaves the Capeni RMJ as a viable and only alternative - until the Russian MS-21 becomes available.

The problem with the Russian aviation industry, for years now, is that they deliver very good engineering however they are a basket case when it comes to understanding business concepts and capitalistic endeavors. In building aircrafts, their business concepts are quite frankly still very confused, being embedded with an inordinate amount of socialist 'approaches'. Really quite unfortunate.

The development cost alone would be pretty big for such a limited production run. It would have to be economically viable to be worthwhile.

Most of the development cost for this project would be spent on system integration and certification processes. The Aircraft as configured here is basically making use of existing technologies and off-the-shelf components! I can easily project that the development cost may not exceed $90 million - $120 million if done in Ukraine. To the West, this may seem implausible.....

The Progress D-36 (formally called Lotarev D-36).



This is the Progress D-36 Series 4 - the basis and the predecessor to the more powerful and advanced Progress D-436 which is shown above! The improvements on this (series 4) over older Lotarevs includes redesigned Fan Blades which feature curved scimitar edges for superior aerodynamics and more efficient performance. It also features improvements in the annular combustor and a newly designed Thrust Reverser component. Progress D-36 is capable of a peak Thrust of 14,300 Ibf ( same as in the YAK-42). Currently this turbofan is offered in the AN-74 aircraft.

YAK is now part of the United Aircraft Corporation (UAC) - a group that is a consolidation of several design bureaus and manufacturing plants from the soviet era. Tupolev, Ilyushin, Yakovlev, Sukhoi and MiG all came to form one giant corporation to compete against Boeing and Airbus. Some of their new products are beginning to show up - the Sukhoi SSJ-100 and the MS-21 which is still in development.

RMJ 423-200 in livery.

This is an early image done before the FAR door requirement and some other issues were resolved. :-)
