Re: LCA News and Discussions

People have been saying a lot with regards to the low production run of LCA mk1 and some for and some against. Wouldn't it be possible to market the LCA mk1 to the third world countries who need a cheap fighter. If we are able to get a order of 20-40 then HAL can increase its production rate and als...

Re: My case against the F-35 for India

What people tend to forget is that as far as the US is concerned F-35 is a pawn in the whole gamut of pieces called USAF. Of course its got a whole lot of techo wizardry, it fits there plan and scheme of things. What we should have should be driven by our needs not by what somebody else is making. w...

Re: AMCA News and Discussions

From what I have read on this forum and elsewhere, current Kaveri's thrust is ~80kN and weight 1.2 T. so for twin engined ~20 T fighter we have TWR , at almost full load ,is 0.8. The same for Rafale is 0.6, EF is 0.76. If we are able to design AMCA with a empty load of 10-12 T ( I am think it would ...

Re: AMCA News and Discussions

Questions to the gurus, in case of the AMCA, wouldn't it be a bit prudent to design the aircraft around the current kaveri that we have, rather than build the jet around a yet to be build engine. This way we avoid falling into the LCA & Marut trap, having the plane ready but no engines to fully ...

Re: Indian Military Aviation

Instead, the IAF's gone for a dream air force strategy: going by their procurements, we're going to have a cutting-edge AF by about 2025, when we have the LCA Mk2, the MMRCA, a presumably improved Su-30, the PAK-FA/FGFA, maybe even the AMCA nearing IOC. We'd be heavily dependent on imports, but wit...

Re: Design your own fighter

I am not sure how the trade off between the inertia of higher mass and higher engine power is when it comes to maneuvering between mountaintops at high altitude. Obviously bigger wings and lower wing loading would make a difference. This is the sort of thing I would experiment with by making plane ...

Re: Design your own fighter

Guru's I have a question regarding the usage of Adour. Since we had been making it under license, is there a cap on the numbers we can make. Do we pay a fixed amount and make as many as we can or do we pay a royalty on every engine that we make. Also if we need to make any modifications how do we ge...

Re: Design your own fighter

Victor, as mentioned earlier having extra power would mean that in desert and plains it can keep higher up easily and avoid manpads. One oberservation, having the gun at the position you have shown, may result into gun smoke being ingested into the air intake, F-5 had that problem earlier and the gu...

Re: Design your own fighter

Shiv sir, Two Adour engines in a 10-12 ton craft would mean there's ample reserve power at hand for great acceleration. This excess power would also mean good hot & high operational performance. This also means that the same craft can be used for deep strikes too. Also such power would mean quic...

Re: Design your own fighter

Victor sir, we need to discount wingtip tanks, as those would add extra weight far from the central axis of the aircraft which would make roll response sluggish. (Angular momentum stuff...) Shiv sir, would it be possible to add a canard in the nose which would provide pitch control. A pitching force...

Re: Design your own fighter

Shiv sir, do we intend to have internal storage of weapons. If so then a low mounted single wing piece would interfere with weapons stowage. Also we should not try to put in all top of the line systems into it. KISS principle should be followed. If stealth is not a very high priority then maybe we c...

Re: Design your own fighter

What prevents us from using modifying the Do-228 to be used as a CAS aircraft? Its internal cabin means we can probably carry weapon loads inside the body. It has a very low stall speed hence ideal, however may not have enough power for high altitude takeoffs.

Re: Design your own fighter

In case the IAF cannot spare a IL-76, would it be possible to buy a second hand one specially for R&D purpose. We can use it to test engine, radars etc.

Also how about using some of the old Canberra's?

Re: Design your own fighter

Shiv sir,

One of the engine options you said was Adour, however don't you think thats its probably has too low thrust to weight ratio. I know a better version is under development, but we do not have license to manufacture that, do we?

Re: Design your own fighter

>> The problem would be that you're designing an air-superiority-only variant when there's no need for one, along with developing a strike fighter that you do need. bit of a waste of time. Point taken. 1) will it be assigned to tank-killing? (in which case a sub-sonic plane is better, more like an A...

Re: Design your own fighter

How difficult would it be to design a fighter and have two versions one air superiority and one attack the difference between the two being in 1. avionics suite 2. Maybe the attack aircraft would use non-after burning version of the same engine Think something like Mig-23 & Mig-27

Re: Design your own fighter

[qoute]Re engines, I'd definitely look at two AL-31s here, in a plane that's much lighter and smaller than the Su-30.[/quote] wouldn't the two eavy engines with there fuel needs, massive intakes mean a fighter almost the size of Su-30. Regarding having dedicated fighters for air superiority & at...

Re: Design your own fighter

I think a single AL-31 engine fits the bill. It has enough thrust that a air superiority version can be designed with more than 1 thrust to weight ratio. Also it has enough grunt that a bomb truck version could easily lift enough load.

Reason I am saying for a single engine is cost.

But wouldn't the radome of all fighters have a radar dish? Isn't that a penalty for all fighters. Please note that I am not saying lets make a new mig-21.

Since we are trying to design a new aircraft with some stealth features, I have a question for the gurus , is a nose air intake like Mig-21 inherently more stealthy since the engines are not visible as they sit behind the cockpit and do we pay huge performance penalty. The reason I am asking is havi...

Re: LCA news and discussion

Aditya I agree with you that we should fill up our ranks with LCA. By 2015 we already would be having large number of MKI and atleast a decent number of MRCA besides the good old 29 and 2000 (later both upgraded). Definitely these would form the sharp cutting edge of the IAF battle axe. But we also ...
