LCA TEJAS MK1 & MK1A: News and Discussion

[Delta Squad]

Does the Mk1 have the refueling probe? IIRC Mk1 does not have that refueling probe.

I believe Mk1 FOC have refueling probe

It does eat up a valuable missile pylon. Tejas with a hammer will carry on only 1 R-77 because the fuckers didn't bother rating the mid-board pylons at be CCM capable (maybe Python-5 will work as it's internally similar to Derby)


This layout is another option that has been used elsewhere.

Tejas won't carry any R-77 because they aren't integrated with the type.

The Tejas Mk1A will carry 2 X ASRAAM on one dual rack outboard pylon and 1 X ASPJ on the other outboard pylon. Center pylons could carry 2 X Astra Mk1. Inboard pylons could carry 2 X AASM Hammers and 1 centerline drop tank.

can we carry dual pylon on inboard pylons, where u suggesting hammers??....for CAP nd air fight we dont need hammers. if we can put 2 bvr like astra 2 or 4 bvr with help of dual pylon in inboard pylon. that make tejas to carry 6 BVR/WVR or 8 BVR/WVR missiles.

Inboard pylons are for drop tanks. Mk1 has a low combat range without them.

Yes it's... odd.

Why don't we use tail-tip jammer pod like normal people?

Integrated jammers have various locations on various aircraft. Typhoon has them in wingtip pods, Rafale's jammer antennas are at hull in front of canards and at tail base above the nozzles, Gripen E has them in wingtip and tail-tip pods.

So if Tejas is to receive integrated jammers, there are options. As for why Tejas has no integrated jammer... well, they probably just didn't think of it. F-15, F-16 and F-18 originally had no integrated EW suite or even just self-protection jammer, and I think many teen-series fighters still don't have such capabilities, though I might be mistaken there.

Center pylons could carry 2 X Astra Mk1

2X Astra on each , right ??

 

[MirageBlue]

Inboard pylons are for drop tanks. Mk1 has a low combat range without them.

Not necessarily. There were recent pics showing 4 X 1000 lb dumb bombs being carried on the inner and mid pylons and a CDT on the center line. It all depends on the mission profile.

 

[MirageBlue]

Not on the Tejas Mk1A. I believe there simply isn't enough clearance, but we haven't seen any concept design of a twin rack for Astra Mk1 on the center pylons.

Yeah clearance is an issue , though I have seen some |- shaped twin rack pylons on modern jet .
Couldn't find that latest pic, But here is that concept on old jets.
Hopefully they make something for center. carrying only one 200kg BVR It would be waste of that 800kg capable pylon.

For our mission profiles, this may be satisfactory and more cost effective as its rare that full loads are carried outside CAS role aircraft in general?

I have some questions for you guys
1. What is the fuel capacity of Tejas. (If possible please do provide your sources)

2. What is it's combat radius

3. Is there any way we can calculate the range of an aircraft based on its fuel capacity, weight of the aircraft, lift to drag ratio and SFC of the engine.

4. Has the fuel capacity been increased in the mk1a variant.

5. Also do any of you have a wiki account, to correct the Tejas data on Wikipedia

And how it compares to F-16 and Gripen with similar payloads and fuel reserves, etc.

1.Internal caapcity 2500KG
4.No change in Mk1a

2.Combat range 30-40% of its ferry range 3000+km, i.e. 900 km with 3 drop tanks (800+800+500). With 2 ASRAAM + 2 Astra BVR (4 possible in future) + ASPJ.
Still agile in this configuration. Not fully loaded.

3.Nope , too much calculation.

5. There isn't much to correct.

6. Not comparable to F16 or GripenE.
+-10% Comparable to Gripen C.

 

[Javelin_Sam]

Wow. Is that a litening pod in underbelly? Also the red thing- any PGM?

Its a pod with cameras to study the behavior of the payload.

I heard from some Twitter account and even alpha defence about some ballast weight being removed by rearranging LRU's and how mk1a will have slightly more fuel capacity as some modifications were made in the fuel system.

 

[stat231]

Is alpha defence a reliable source?
