well, back to topic. The Russians did demonstrate a TVC equiped Al-31FN back at the Zhuhai airshow in 02, and I don't think Jane is THAT unreliable.

well, when the deal was first signed, how come no info on a TVC engine was revealed? i was undert the impression the al-31s ordered were regualr fns.

well, if you look at the regular AL-31FN, they are 2.8 million each and this one is 3 million each. Maybe that extra 200,000 is for the TVC? if you look at the full Janes article in the other thread, it looks like China is getting TVC engines for the other flankers too.

200000 is a bit cheap for tvc. tvc would incorperate at least a 40% increase in cost.maybe these engines are improved for reliability or thrust.

The Russian engines aren't going to get more reliable, lol. You are hoping for a miracle here. When it talks about improved, I'm guessing it's either going to be AL-31FM or AL-31FM1

My thoughts about russian engines

The problem with russian engines is not reliablilty or power. Its their service life.

Its measured in the hundreds of hours comapared to the thousands of hours with western engines.

proof? russian nuclear engines are very unreliable because of poor safety standards. thsi creates an impression that all russian engines are bad. but thats so wrong. russian tank engies actually are more reliable and less gas guzzling than wetern designs. russian jet engines have great performance and life. as long as the chinese told salyut to inspect for quality.
