The very definition of elegance and beauty..

That title now goes to LCA ji

Another shot that looks like SP-24, the latest FOC fighter to fly.

Nah, not in my opinion..the LCA is a looker no doubt, but the Mirage-2000 is simply the most beautiful of all, IMO. The proportions are simply perfect and the curves..one couldn't do it better.

That image you posted actually got me thinking..now that there are so many digital artists out there with great PS skills, it would be amazing to see a Tejas in Mirage-2000 like blue/grey camouflage scheme. Just for kicks.

[nachiket]

Does anyone know why the Mirages were never repainted in Tipnis grey? Every other IAF fighter lost the various camo schemes they used to be painted in.

[Indranil]

Kartik, I agree with you that the Mirages are gorgeous. That's what 5 generation of iterations buys you. Mk1 does not have that refined lines. And I told these to people who fly and developed the Mk1. It is like telling somebody that their child is ugly.

How I wish there is an Mk1B. 0.5mtr longer with everything smoothed out.
1. only 2 slats
2. optimized LG, structure and reduction of balance weights
3. wingtip pylons
4. smoothened aft-canopy and engine bay regions
5. shoulder mounted gun, fuselage pylon in it's place
6. 0.5 tons of more fuel
7. elongated and canted intakes like on the Mk2 for lower wave drag.

ADA/HAL can basically get that aircraft to weigh the same as the current Mk1A. M It won't be as flexible as the Mk2, but it will be hotter rod. It will look, accelerate and turn better than the Mk2.

[Jaeger]

Sounds like what Tejas would've been without the need to match the MiG-21 footprint exactly.
But a question, Indranil: why the splitter plate intakes? Forget DSI if one were to look at 4G a/c, they seem more like the Hornet rather than the Super Hornet. Even the KAI T-50 has no splitter plates. Will Mk.2 intakes be substantially different?

[Cybaru]

The amount of effort that will go once there is a design change will be the same whether it is 0.5 meters or 1.3 meters bigger, correct? If that is the case, I love the 3400 Kgs internal fuel and 6500 KGs external payload capacity of Mk2!

You are talking about the shape of the intake. The splitter plate is present for all intakes which aren't DSI. On the Super Hornet, T-50 and F-22 the shape and size of the intakes just hides that fact. On the Tejas, the size of the opening is smaller than the size of the splitter plate giving it a different look.

Actually each of these intakes are different. For a supersonic fixed inlet, some shocks can be beneficial in slowing the air down before the inlet. This becomes especially important when the inlet is in a completely free stream.

Splitter plates can be designed to serve two purposes. Separate the boundary layer and create the shocks.





There are alternatives as well including using the wing LE like in the LCA Mk1. In the Superhornet, the inside and top wall of the inlet is designed in a way to create those shocks.


I am not sure how it works in the KAI-T50. Most probably, its proximity to the LE of the LERX provides the shielding.

[Jaeger]

Thanks nachiket and Indranil. I think I understand about the size + type of inlet. A follow-up: the Mk1 like the F/A-18, has a little "vent" (?) in the wing, above the intake, which the Shornet doesn't have:


Is that like a bypass system for airflow?

[Mort Walker]

This seems to be as good of a place to post this.

Beautiful newly upgraded Jaguar DARIN 3 in primer..one of the clearest shots of this elusive big cat.
