The choice of placing a canard will change the design, most probably this can only be done in Mk2 variant. nevertheless considering the pilot's cockpit has to be either enlarged to fit the actuator and mechanical assembly, or the the delta shaped wings would have to be reduced which isn't an option.

Latter option will result in less fuel hence the former design choice will be selected. But that would also mean a bit of structural length to be increased, as mentioned by fellow members over here.

In contrast, we all regress from the very simplistic aspect of the plane to have an existence is because we had to replace Mig21s and embrace reliability of jets such as Mirage 2000.

HAL to get Tejas key parts from private players


NEW DELHI: State-owned defence manufacturer Hindustan Aeronautics Ltd is looking to significantly increase the involvement of private companies in manufacturing Tejas combat jets even as readies for an additional order for about 200 units of the latest Tejas model, government officials said. Hindustan Aeronautics Ltd (HAL) has already roped in private players including L&T to make key components for 123 Tejas Mark 1 and 1A light combat aircraft (LCAs) that it is building for Indian Air Force(IAF).

In the long run, HAL plans to play the role of a system integrator with private firms doing most of the manufacturing, the sources said.

With the private sector participation, HAL’s per year production capacity of Tejas is expected to scale up to 24, officials said. Out of 123 combat jets the company is making for IAF, 40 are Mark 1 version and the remaining 83 are Mark 1A version. In the case of the 83 Tejas Mark 1A jets, HAL intends to make use of L&T’s capabilities for making wings of the aircraft, while Dynamatic Technologies Ltd is expected to make the front fuselage, or main body, VEM Technologies the centre fuselage and Alpha Doca would make the rear fuselage, officials said. “We have placed orders (for the 83 Tejas) with these firms, who will make the parts and if they are successful the parts will be integrated,” one of the sources said.

HAL will work with the private sector to make components for the 40 Mark 1jets as well. “This will ensure that the private sector becomes tier 1 suppliers and can ramp up their supply chain,” the person said. HAL is also looking at bringing the private sector to work on Tejas Mark 2 version. “This will be a game changer for the private sector. In this, HAL is looking at being a systems integrator, while the private firms will be the manufacturers. This will increase production,” one of the sources said.

IAF wants to induct 201 Mark 2 Tejas jets, which will have additional capabilities such as better range than the Mark 1and 1A. “The Mark 2 will have qualities like the Gripen and Mirage fighters and will be called Medium Combat Aircraft instead of LCA,” one of the officials said. The order for Mark 2 will be placed once HAL understands what all capabilities IAF wants in the aircraft.

So, after decades of glory for Gnat...Mig-21...& hopefully Tejas Mk1A, the light fighter era in Indian Air Force is finally about to end!

The age of single role aircraft ended long ago, the age of heavier multi-role aircraft is at hand. Out with the old in with the new.

Taking cue from this, can we drop "LCA" from all future references to Tejas? That acronym has lived well past its sell by date
Yeah sure. IAF version is not even called LCA anymore. It's Tejas only.

Idiots reporters in india
MK 2 WILL BE LIKE GRIPEN E
AND MK1 IS ALREADY GRIPEN C/D TYPE AIRCRAFT
Don't expect such details from these reporters. Very few are fully correct ever.

Distinguishing between E model from C/D is far from abilities of many of these. Often they will use pictures of other aircraft in acticles on Tejas. So just ignore.

Few drawings.

Loaded Weight with 3400Kg fuel: 11400 kg.

Combat load(not exceding) at MTOW: 5000 kg

TWR with internal fuel: 0.87

I was astonished to see Empty Weight of Gripen E at 8000 kg which is now 1000 kg above the earlier mentioned weight of 7000 KG(see sheet below) for NG model and 400kgs above E model.

When SAAB had submitted the proposal for MRCA-1 and SEF then it's fact sheet was as such(below). Today it is as in above sheet. Still not to forget that Gripen E hasn't finished development yet.

So the obvious question is how did IAF allowed such a fighter to be part of two successive tenders and almost openly favoured it (during SEF) when its specifications are not even frozen?

Does this mean that Tejas MK2 will also get a weight increase to 7.2 tonnes?

Also, I read somewhere that Tejas uses 2 R73 missiles at the edge of the wings to maintain the shape of the wing by exerting weight. This pair of R73 with pyolons are also weighed in while measuring the empty weight. How true is this?

Since the weight of the engine is increasing, payload capacity and internal fuel volume are also increasing, the fuselage is getting longer and canards are being added. So by thumb rule, the Empty weight will also increase. How much time will tell.

However, I expect it to be under 7500 kgs.

I have heard similar stories during initial days of Tejas. Then was always seen with R-73 (dummy or live) right from maiden flight. But today SPs fly on their first sorties without R-73. So I would not agree to it. However, i can't say so if launch rails are excluded or included in Empty Weight. Maybe in loaded weight they sure are.

Just put 2 engines on Tejas and make it as close to Mig 35 as possible (I say mig 35 coz it feels more reasonable and achievable)...then we will have a good filler aircraft that can handle all roles...a good..cheap...indigenous...4.5 gen...mass produceable..rugged...easily upgradeable...second line fighter...isnt that the dream when u have a multiple front war to take care of :)

This would be able to take off a lot of load from frontline fighters in a war scenario...

...and ofcouse...later... AMCA comes in for frontlines....

Developing a 4.5+ generation flanker like aircraft is definitely a requirement if we want to establish ourselves in aeronautical industry but that isn't easy to do.

It may be easy for people to say "lolz just add one more engine and flyz it" but hard to do on ground.

Just by putting one more engine Mirage 4000 was first flown in 1979. And could enter into service only in 2001 in its much-refined avatar as Rafale. That's 22 years for an experienced player like Dassault.

So let the guy have his time. He will learn in due course.

You r right and it is easy too as ADA can put 2nd engine under central pylons which is for that unnecessary fuel tank . Genius

There is nothing called "putting one more engine". It is simply redesigning entire plane.

India already makes Su30 in HAL, including the engine Al31FP which is made from raw material stage. It can carry a payload of 10+ ton and fuel of 12000 litres. So, I don't really see a problem in long range missions with heavy payloads to redesign Tejas as twin engine fighter.

India needs 3 planes - Su30 MKI, Tejas MK2 and AMCA. Having additional planes only cause logistical problems. Even Rafale will be wasteful by the time the 36 planes are delivered in 2023 as Tejas MK2 will be ready at the same time

looking at this i seriously doubt about capabilities of gripen and saab
saab seems rouge company look at fake figures company show off to public thank god we r not buying this crap 80kn thrust and 5ton payload lol bullshit:bs: even out tejas doesn't have such payload with 84kn engine:mad2::mad2:

Are you getting serious? We were only having our time with a new guy.
