This question has been asked a few times already.
Lets, look at the civil industry first, in the last 10 years Russia produced only 22 civil airliners. In 1999 only one airplane was delivered. (Il-96-300 Domodedovo Airlines RA-96013) This year one Il-96-300 and one Tu-204-100 will be sold and possibly the last new Tu-154Ms. This are very bad figures esspecially when compared to 1991. In 1991 26% of world wide civil aircraft fleet was build in USSR.
The major problem with Russia is that if you want to buy a Russian airplane you must pay the full price in cash, there basically exists no dependeble leasing companys. However, this August for the first time one Tu-204-100 will be sold via a one new leasing company. If this deal works more will come for sure, I hope!
This is how I see the future of Russian Civil Aircraft industry. For the next 10 years at least Russian aircraft will only be sold in Russia, with very small orders from 3rd world nations. Yes, I am sure that they will still exist in 10 years time! There is a great need of new airliners in Russia in the next 5 years, most of the current fleet will have to be withdrawn from service at that time. There is no way Russian Airlines will turn towards Western planes (maybe Aeroflot will), not because they don't want to, but beacuse most carriers will not be able to afford such expensive items.
As for the millitary industry if China and India keep on buying Russian weapons the industry should be ok. Most of the new projects are financed by this two nations or by the money invested from sales.
Il-96-300 and Tu-204 respectively were world's 2nd and 3rd civil airliners to utilise a FBW control system. I am sure that when this airliners first came out they were up to date with their western counterparts. Now, even though I really like Tupolevs and Ilyushins, I would have to say they are becoming out dated, I mean both Il-96 and Tu-204 use a 10+ year old technology.
Please, correct me if I'm wrong!
