problem is ARJ-21 is just not an advanced design by any imagination. On top of that, it uses the same generation of engine as E-Jet series despite coming over a decade later. Compared to that, Russia's SSJ-100 use SAM-146 engine which is half a generation newer in efficiency and a full generation ahead in terms of maintenance. And MRJ, which uses an engine that's a full generation newer. It wouldn't have been a problem had it actually gone into service on time, but it didn't.
As i said before, all the airliners are getting larger. The 30 to 50 seats jets are getting completely removed from service. Bombardier and Embraer are no longer investing into the 70 to 90 seat market. Airliners are now looking at 90+ seat class of airliners to replace all of that. It looks like COMAC is effectively doing that when you consider how slowly ARJ-21 has been moving forward. All the resources are going to C919.
The one in the link is definitely not a mock up. It's a model at best. To construct a mock up you need a detail design of the plane first which I doubt either side have a clue yet beside it being a wide body jet.Reuters article about the joint sino-russian wide-body projet. A mock-up of the plane was presented, and more information about the projet.
So, is the ARJ-21 a white elephant?
The fact the ARJ-21 has 400 orders in the bag is sufficient and enough said
"Good" comment from you on 1 out of 588 words of that article. Very "insightful". Anything that we don't already know?The one in the link is definitely not a mock up. It's a model at best.
