At that scale too it'll make a good swarm drone. Size would make it super steslthy & would carry a good few kilos warhead.

Yes, Imagine a single twin seater fighter plane with all these new goodies can create mayhem. Porkistan doesn’t have such technology, neither China. They (china) can try to fool the world as much as they want but won’t succeed.

In his simulation studies in Beta coefficient, Vivek Ahuja had written that any reduction in weight of Tejas from this level will give Tejas a major advantage against Pak F 16 in within visual range combat at all level. Weight reduction has a major advantage in close combat. Actually, the initial MK 2 design which was proposed to be half a meter longer has a weight of 6100 kg. That was a very impressive design in which 400 KG weight reduction with half a meter long fuselage and half a meter longer nosecone was planned. Weight reduction and aerodynamic Improvement hold the key for development of Tejas as a formidable flying platform.

Any delta platform has a natural high drag element to it which becomes a problem in a turning fight. In which case high excess power is the key. Its for this reason that the Typhoon is amazing at A2A roles despite being a delta wing platform. The same holds true for LCA. As we reduce weight, we also must try to put a 120+ KN power plant on it. And increase onboard electrical power for EW work. Recall that the Gripen E has wingtip mounted banana shaped EW pods which also seems to have CC missile rails mounted on them.

Suddenly development pace seems to have boosted. Thanks to LCA deal.

finally the day arrives,

Tejas mk1A good to Go , with 83 fighter deal signed


nation owes a lot to the design team led by Kota Harinarayana,

he deserves a bharath Rathna fr this, nothing less

 

[Defcon 1]

Finally !!!

True, Scientist need more attention from government.

Will HAL adopt co cured and co bonded wing fr Tejas Mk1A,(if so we can look at some weigh reduction

or

Is it already done in Mk1 itself?

AESA cooling unit will replace the ballast led plates of tejas mk1

we hv no news about any landing gear redesign also

We are yet to see news about any effort to reduce tejas mk1A weight.

ALready DRDO has said that LSP 3 achieved 8.5 G

further reduction in weight or fine tuning of FCS may lead to 9G , who knows

 

[porky_kicker]

@Bleh @porky_kicker found something. Is this legit?

Some info is missing , some ifo is legit but cannot confirm some info , need official confirmation to be sure.

 

[ersakthivel]

This is the one which achieved 8.5G as per DRDO

Yes, There are many areas where the weigh reduction is possible. Many parts were overengineered as this was our first effort in 4th generation. I have read somewhere that Tejas has 400 KGs of cable, it is possible to reduce their weight by half. Landing gear has its legacy in Jaguar. Its weight reduction is very much possible provided we do some research work on it. We actually do not know what is happening. However, 6% drag reduction and few hundred KG weigh reduction which have read in many open sources. Let us hope that it is true and we see Tejas MK1+ around 6000 KG with improved aerodynamics.

I don't know much either.

You can tell that one of the cruise missiles have active-radar guidance & another has TV guidance.

That drag-optimised fuel tank have been altered to carry swarm drones, maybe... Looks same.

The fruits of indigenous developemnt,

Tejas mk1A will only get more lethal from this point on,

If the news about the 80 nautical mile tracking range of ELTA 2052 based 70 KG ASEA on Jaguar is any indication,

tejas mk1A will hv a tracking range good enough to unleash all these cutting edge weapons from a good stand off range,

UTTAM will raise this game to a whole new level, no doubt about that,

ADA has silenced itts critics once fr all with this single picture

Think Tank Water tank " Sukhoi Thermocline" experts hv already gone into stealth mode with radar silence fr the past two days clearly says a lot,,,,

6 percent drag reduction will come from the better surface finish of wings and fuselage from the new cutting edge production line, It has no connection with weight reduction, as far as I know

I was eagerly looking at themocline eggspurt's TL on twitter,

NO REACTION,,,,,,,,,

I had a nasty fight with this sloth on twitter once over his "informed" opinion on Tejas.

Good to see this guys turning turtle , in the face of the continued pace of teja developments,

and its new age weapons and sub systems development,

Nothing gives me more satisfaction that,,,,





Tejas was designed with area ruling as a prerequisite in computed simulation models , few niggles at front fuselage of tejas on this score , was due to the fact that it has to carry a larger radar(bigger than rafale ) while fitting within the smaller hanger of Mig21s at front line airbases,(which limits fuselage length) and its spec which asked fr operations with meaningful load from LEH and high ITR led to low wing loading design ,

leading to compromise at some points of area ruling curve ,

These new age weapons like CATS hunter makes the few kinematic shortfalls of Tejas mk1 pale into shadows.

What you say is right but some other design changes are also identified such as canopy redesign etc. This aerodynamic improvement will reduce the drag which will result into 2% increase in top speed, 20% improvement in transonic acceleration, STR 18* per second etc.
