Engine problem in Sukhoi caused by outside of the EngineMost of the engine failures were originating from outside the engine of Su30MKI and neither were their similar engine failures being reported from other air forces operating the aircraft or its versions.
Parrikar attributed the failures to faulty bearings that contaminated the plane's oil supply. It seems that metal fatigue led to tiny pieces of metal shearing off the friction-reducing bearings, which then entered the oil system.
This accounted for 33 of 69 engine failures.
Another 11 failures were the result of engine vibrations, while eight more arose from a lack of pressure in that same lubricating oil. New Delhi has not revealed the cause for the remaining 17 incidents.
AL 31 Costs - $ 3 Millions link Estimated Value in 2004Besides they have mentioned that post the changes suggested engines were flying as many hours as were promised.
In any case the Russian engines are so cheap and engine change is such a plug and play activity that you can simply begin to stock more engines for sukhoi. Given the price differential it hardly matters.
PROVIDE your Source chips in Fuel/oilAre you sure that the chips in the oil were because of the engines?
oh ..Seems Just like Changing the ball bearings in Motor CycleIf the chips were originating in the engine then why did they accept the solution with regard to better fitment of bearings and better quality oil and changes to maintenance schedule.
Can you simply change the bearings in the engines, so easily, that only general maintenance SOPs get affected and no need arises for major overhaulings?
then provide me a Better source, I'm waitingRegards prices of engines, should you work out the arithmetic in your links you will get the exact differential cost and it is as I claim. The Russian ones are cheaper by almost a margin of 2. Moreover for the whole plane you will have to bump up the cost by a mere 3 million even if we take your erroneous estimates.
provide your source about flight hours and Engine Range ..!!Moreover do you realize you are talking about uber expensive French engines and not the American ones which have the benefit of the largest production runs in the universe and yet turn out expensive hour for hour.
Sukhoi-30 MKI, Air Force's Most Modern Fighter Jet, Plagued by Engine TroublePROVIDE your Source chips in Fuel/oil
Thats 33+11+8 that had only as much to do with "engines" as could have been managed by something as dumb as better lubrication, better fitment of bearings and better quality of oil.Su-30 Fleet Plagued By Engine Woes, Poor Serviceability
(Source: Hindustan Times; published Mar 17, 2015)
Parrikar said India had resolved the bearing problem by "arranging better lubrication (to prevent wear and tear), better fitment of bearings and better quality of oil."
"Out of total 69 cases in the last three years, 33 cases are due to finding of chips in the oil, 11 due to vibration in the engine (caused by bearing problem) and 8 cases because of low pressure of lubricating oil," Parrikar said in a detailed reply in the House. In all, engines coming in for overhaul will have nine modifications.
"Serviceability has improved by 7% in last 8-9 months to reach to 56-57%," he said. The earliest Su-30s were inducted into the IAF in 2000.
"The number of mid-air engine failures is not shocking factoring in the flying hours the fleet has logged. But poor serviceability is a matter of concern. Ideally, it should be around 75% during peacetime," former IAF chief Air Chief Marshal PV Naik told HT.
Mujhe kya bata rahe ho bhai. If it is a major trouble then everybody would expect a major change in how bearings are manufactured. Did you hear anything of the sort. My claim is that it was all a ruse to get the Rafale in by sabotaging the chances of Su30MKI. Which is to be expected from a system that was bred by the C system.oh ..Seems Just like Changing the ball bearings in Motor Cycle
You did not get it, perhaps so I will repeat.then provide me a Better source, I'm waiting
provide your source about flight hours and Engine Range ..!!
Bad comparison of planes above, I suggest that you compare Su-31MK1 and Rafale with Pakistani planes and Chinese planes which can be stationed in Tibet (not mainland China).
See what F-16 (what Pakistan has) or JF (Chinese made) compare with Indian planes.
Chinese airforce is 80% old and outmoded planes only good for training. There are less than 200 modern planes with copied technology with the Chinese Airforce, who can confront IAF. Moreover all these cannot be positioned in Tibet.
Hence, please modify the discussion from comparing IAF internally, compare it with what the adversary has.
it is true in the real war the you pit your strong planes/forces against the enemy's weak planes/forces. it is foolish to do the contrary. you use platforms/aircrafts to achieve certain well defined objectives. The type of platform changes according to the objectives and assets/tactics required to achieve those objectives.Pardon my ignorance but why should this vs. debate be avoided. Is it because it is fashionable to not admit that it is simply too real or is it because it is fashionable.
What would you rather say to the ACM of PLAAF. I am bringing an MKI and you must now bring only the J-11. Otherwise it we will have the Red-flag think tank modelers call a foul - chinese romanchi kha rahe hain.
An unequal fight is the only real way to fight. If that is agreeable then why must we refrain from vs. debates.
I would give the edge to the Rafail, Su 30 has a radar signature 4 times as large as the Rafail and as the ability of radar missiles grow,, the larger signature plane will all ways be the bigger and better target. Dog Fighting has largely been a thing of the past for along time. Its a romanatic vision of air warfare that has not existed for a long time and never did exist to the extent people think. Air warfare 90 is a war of ambushs.
Your information is incorrect. China has 3 times 4th and 4++ generation fighters. Copied or not is not the issue.Chinese airforce is 80% old and outmoded planes only good for training. There are less than 200 modern planes with copied technology with the Chinese Airforce, who can confront IAF. Moreover all these cannot be positioned in Tibet.

a less capable plane in the hand of a skilled pilot with right tactics can become pain in the a**.
India has an estimated 210 Su-30 now. Even at 55% availability rate, India can put some 120 Su-30 in the air at any given time.
This is the force that deters Pakistan from engaging in adventures across LOC. A Su-30 can shoot a PAF plane FROM INSIDE INDIAN TERRITORY due to its very long range radar and long range BVR missiles.
I have been told that Su-30s can see PAF planes taking off from PAF bases from Indian territory.
Anybody who talks down Su-30 is crazy.
Rafale is very far from being a valuable asset in IAF.
Su-30 and Rafale are basically same generation planes though coming from two different countries and representing different maturity and technical expertise. This does not make Su-30 a bad fighter. The only "big" downside of Su-30 is RCS as it is a big plane and not designed with RCS reducing techniques. There is no other big downside.
@RayYour information is incorrect. China has 3 times 4th and 4++ generation fighters. Copied or not is not the issue.
