The current round of "merit of Sino-Russo JV for C929" was started as one member stated his disappointment of China not going alone with C929, but without providing any reason as why/what he is disappointed.

Then members provided various examples of the Russian values to the JV, mostly on Russian experiences, but also commercial and strategic/political values.

Providing a technical reason is in no way denying other reasons and neither can itself be denied.

Airbus group is a very good example right in front of us, started by France, Germany, Spain and UK (BAE). All of them had separate experiences in aero-industry, in different technical areas. Maybe France was overall strongest with a full (relatively) set of knowhow, others have better things to offer in a certain area.

Nobody criticize the formation of Airbus, nor is anybody disappointed on France not going on alone, nor dismissing the added value by Spain (the weakest?).

Why now on COMAC-UAC? Why on Russia? Is it the 50-50% share? As of now, France and Germany all have 11.1% share of Airbus Group SE and Germany has never designed and produced a jet aircraft since end of WWII while France did all.

I am not a Russophile, but the part of dismissing Russia and USSR in the current discussion really confuse me.

It's pretty clear that China got into this partnership with UAC because it thinks Russia has something to offer in their experience and technological expertise. People don't really need speculate for any other purposes.

If you guys want to compare China and Russian passenger jet technology, its very simple.

Compare C-919 and Russia MC-21, both aircraft belong to the same class, both seats about 150 passenger, both are around 38 meters long, both program also started almost exact same time, C919 program started 2008, MC-21 started 2006.

And guess what? Both aircraft flow at almost exact same time, C-919 few weeks ago MC-21 yesterday.

Also its funny that both program are developed individually on each country's own effort.

Whats a better way to compare the 2 program and end result to see how they stack up each other?

Different development strategy will result in different timeline. It looks as if MC-21 had already finished their static stress tests before doing their maiden flight. I believe C919 has not finished this yet.
To make a fair comparison, you'll need to wait until both finish all tests and handover is done to the launch customer.

Not necessarily, both aircraft is pretty much 99% done, so a comparison right now is pretty accurate.

People compare J20 vs F35 vs F22 vs T50 all the time even with less public information, and 3/4 of those are still in development.

My point is, if C919 and MC21 are similar in technology then the decision to partner up with Russia is a political decision, this is my personal guess.

If C919 is slightly better than MC21, then partner up with Russia is purely political

If MC21 is superior than C919 in design, then its in China's interest to partner up with Russia.

But overall better doesn't mean superior in all aspects with nothing to learn from the other model. I'm sure that of the C919 and MC21, each design is superior over the other in some way. For example, maybe one aircraft reduces weight by using superior material while the other aircraft reduces weight by using innovative manufacturing technique. Which actually came out a little lighter may not be the point so much as that when you combine the best of these approaches, you can get further weight reduction and fuel savings leading to a design that is superior to both of its predecessors.
