Tejas Mk2 (Medium Weight Fighter) - News and discussions

As said before, related to Mk2 and GE414 engine. Audio was a bit iffy so some parts are a bit hard to understand, but you get the gist.

No just no. Stop your Chinese propaganda. JF-17 is no match to Tejas MK1A. Acceleration, turn rates, wing loading, use of composites, lower RCS, better weapons and most importantly much superior engine. Tejas MK1A is just going to be ahead of any JF-17, period.
tejas uses tailleless delta wing, it has the advantage of low wing load to ensure a high instantaneous turning rate, but also has obvious disadvantages. Due to the low aspect ratio of wing, the lift coefficient at the same Angle of attack is also low.
Moreover, the aspect ratio of Tejas is about 1.83, which is smaller than that of Mirage 2000 (2.03), which further magnates this shortcoming. The smaller the aspect ratio, the greater the induced drag and the smaller the lift coefficient. This is why no one adopted tailless delta wing after Mirage 2000
Wikipedia can tell you all these things,

Tejas has cranked Delta. It somewhat helps its STR. We know about the drag problem, that's why MK2 has slightly longer fuselage.

Despite all these shortcomings, in an one versus one comparo, Tejas MK1A walks all over JF-17, period. Just a comparison of MK1A's liquid cooled AESA radar vs air cooled one of JF-17 is good enough to end this debate.

Why are you bringing up the JF-17 when chicoms don't even fly it? It's an inferior plane by their standards. :rolleyes:

I saw the JF17 pilot interview, when talking about Mirage 2000, he talked about being careful with the first intersection and then taking advantage of the delta wing's fast deceleration to shoot it down, I think the same is true for tejas, as I said above, low lift coefficient, poor ability to maintain speed, tejas will slow down faster than M2000 unless they can get higher T/W,
As for high Angle of attack maneuverability, although delta wings can create eddies to increase lift, the lack of canards can cause the eddies to collapse prematurely. JF17's large blade wings can also create eddies, and high Angle of attack maneuverability is not bad either

Mirage-2000 is pure Delta whilst Tejas is cranked Delta. There lies the difference between their handling and STR.

This is my last reply to you regarding Tejas vs JF-17. Rest, whatever floats your boat;)

The cranked Delta wing is to increase the aspect ratio of the wing, to increase the lift coefficient, to increase subsonic maneuverability. After all, HAL is not stupid, and when I say shortcomings, they can't be unaware of it

The LCA has been designed to take advantage of the first intersection and finish the fight. After the first minute, the LCA would run away instead of getting into a turning fight.

Today, with the fourth generation combat bombs like the PL10 in service, it is impossible for air combat to detach after entering the WVR. Facing the JF17, Tejas should seek one cricle flight to take advantage of the advantage of instant turning, which will not exceed 30 seconds

Depends on the situation. The JF-17 has to survive the LCA's first shot before it can do anything.

So were you okay with over dependence on US engines? I've said this before, US engines are 'by far' the best. But Tejas MK1/1A, MK2, AMCA, TEDBF...we can't make our future IAF fleet over dependent on US' will.

It was a mistake to go with US engines for Tejas family, when a much safer French option was always on the table.

About current situation, well better to be safe than sorry, IMO.
Could it be an AMCA?

I think that Indian time and French time are not the same: you are always looking to have even more, even better, without giving the time you lose its true value.

Probably price, historically we were shortsighted always. We would like to have hard earned technology at free of costs, because we purchased 36 rafales from them.

What is the reason we are unable to close a deal with France- despite promising results from Project Turenne, leaving the door open for Americans to squeeze through?



I doubt price is the reason.

The first deal with France for an LCA engine based on the M88-3/4 was very likely destroyed by the American offer of 100% ToT for the F414. It makes sense for India to not replace the F414 on LCA. It de-risks the program too.

The decision for AMCA's engine is still pending. With Rolls-Royce stuck in a new graft scam, it appears the Americans and French are fighting it out. We could see a decision made this year, perhaps in a few weeks.
