LCA Tejas at Iron Fist 2013

[janon]

@anant_s and others:
Has to be the harrier trainer, due to the similar size as other harriers, and the "Nausena" written on its tail.

Good Work Mate! As-usual

-------------------------------

By the way, which missile is that which was fired at 1:40 - 1:52 and hit the flare ?

:

Thanks!

I assume it's the R-73

@Abingdonboy Downloaded the video in full HD...and one more in the same res. Oh the joy..

Add to that S-Duct's post about the RCS reduction measures on the LCA and in general with regard to our aviation industry:-

A good day indeed.

?? The nose looks like a Hawk and the seat alignment is also similar to a Hawk.

It's a Harrier Trainer:

Don't know if anyone else has picked this up:

LCA taking out an off-boresight target using the DASH HMDS and R-73.
@sancho I'm sure you'd find this interesting.

Last night only discussed about it with my friend..

Just realised that the pic that I added in my earlier post doesn't work, so here once again:

Look at this picture to realize how tiny they managed to make it. That's the Tejas parked near the navy's sea harriers. Both aircrafts have the same weight. But Tejas seems to be half the size, can carry more payload, and has more hardpoints. The small size and use of composites means a much lighter RCS.

By the way the harriers are no big beasts either. Tejas would be almost negligibly small near an MKI or F-18.

use of composites eliminate stress concentration, brings down cost, shorter assemble time, ensure superior structural integrity and etc. but it's not a significant RCS reduction measure. goodday

Additionally, especially considering the future naval variant, Composites are immune to corrosion and when operating at sea level or at sea this is very important.

More important are RAM coatings of course, but replacing metalparts that reflects radar waves with composited will add to a lower RCS for sure too.
The post important part however is the design of the fighter and here LCA was clearly developed with a low RCS in mind, with the small size and the lack of additional control surfaces.

Most sources say that certain composite materials (dielectric ones) reflect radar waves far less than metal, and so reduce the RCS of the aircraft:

Stealth Aircraft

the B-2's composite materials, special coatings and flying-wing design all contribute to its "stealthiness."

Lockheed SR-71 Blackbird - Smithsonian National Air and Space Museum

vertical tail fins are constructed of a composite (laminated plastic-type material) to reduce radar cross-section

Stealth Aircraft - Stealth Materials

composite materials can reduce heat transfer, resist conduction of electricity, limit reflection of radar waves, are flexible but strong, and can be fairly easily formed into complex shapes during manufacturing.

The RCS reduction resulting from the use of composite materials may not be as significant as that resulting from stealth shaping. But surely they reflect less than metals.

janon,
Nobody denying the fact, Composites do reduce the RCS of a object but "far less" is not the correct word as most people claim it with internet links. in the case of LCA, RAM and design changes play major role "without" compromising it's aerodynamic performance. Thanks

Additionally, especially considering the future naval variant, Composites are immune to corrosion and when operating at sea level or at sea this is very important.

Thanks, forgot to mention that

yes

 

[invincible]

Not an expert so can't help asking...What more parameters are left for tejas to be inducted in IAF? And is work on full swing

 

[jiki]

Salient points:

1. Agility
2. Asymmetric loading
3. Griffin LGB drop
4. IR missile launch and target chaff hit
5. Chaff disposal
6. nice views

Missed da chance to be the first finder due to no connectivity to internet bloody hell MTS got canceled in Pune
Now tears in eyes really we have done smthng really gr8 in those yrs wht to say its not at all a lca its just sexy beast
DASH is awsome .... with longer version of mk2 its defntly gonna be our version of F-16 and better then that . IAF shouldn't try to waste this effort, shud order at least 250-300 of it with the upgrd of mk-3 also.....the only concern is the engine but surely hope full for the good results in future may not be kaveri may be krisna .godavri ohh wht ever it may be .... i don no wht to say and wht not to i acn writ 2 pg article on it originally said i m insane after watchig it:

 

[Storm Force]

CANT BELIEVE WE STIL FLY 130+ MIG21 BISONS

WHEN THIS LCA TEJAS IS READY NOW

GO FOR IT IAF what u waiting for
