V22 wing span is 14m & with rotor it reaches ~25m. But IN is interested in E-2Hawkeye & IN also considering this for Vikramaditya.
What I am seeing is practical problems of E2 in Vikramaditya, right now it will use 6 KA31, which gave it 24*7 monitoring capability in any war time. So simply can it need to take 3 E2 for same output, so can it do that---answer is NO.
It needs more fuel, maintenance headache, which will reduce carriers capability.
Also few other fatal problems with this system, which doesn't make it feasible for small carrier like Vikramaditya. May be we can see it in next IAC, which is plane to introduce in 2017.
--Inefficiency in hovering operations makes it a bad choice. Not to forget it has failed to meet threshold requirements for survivable emergency landing.
--The V-22 weighs twice as much as the old CH-46E, burns twice as much fuel, but can only carry the same payload and number of passengers.
--Yet the program has refused to test a one engine out vertical landing of a loaded V-22. They say a V-22 can convert to the airplane mode and land safely at an airfield with a rolling landing with just one engine.
--Another problem is the V-22 uses a unique lightweight 5000 psi hydraulic system that caused many problems in the past, spouting leaks 171 times during operational testing in 2000 and was the primary cause of the latest fatal crash. Helicopters use larger and heavier 3000psi systems with stainless steel lines. While titanium is stronger than stainless steel, it is more brittle, more costly, and more difficult to manufacture.
Although it provide unique capability for missions, but just the market of future heli they also provideing same capability with lesser complexity. As IAF put it as a future plateform and there are lot of project in pipeline; I can not see bright future of V22 in IAF though.
