LCA TEJAS MK1 & MK1A: News and Discussion

[Bleh]

Will LCA MK1 or LCA MKIA have MAWS? Has IAF introduced MAWS successfully in any aircraft in its fleet?

No, they feel its effectiveness is too short-ranged & too many false alarms with present tech... Only AMCA with multiple radars may have MAWS.

No MWAS is for MWF and AMCA not for LCA MK1A.

IAF helicopters have maws. For fighter jet currentl maws tech has many false alarm.

So we are developing dual color maws for su30mki which will also go into mwf / tedbf and later even better tech in AMCA .

Are all the values correct... Someone double-check.

Service ceiling is higher, and is comabt radius of MWF 1,900 KM ?

Service ceiling is 50,000ft ie 15,2X0m... 16,000m of wiki may actually be an over estimation.

About the combat radius, the 1900km I checked has no source reference. Almost 4 times of Tejas on internal fuel seems bit of a stretch... Fuel isnt that much more & more powerful engine too.
I read 1500km once on BRF, so I decided to play safe & go with that value.

Lca combat radius is more than 500km.
Anyway combat radius is meaningless figure. For air to air mission it could be much higher compared to heavy strike mission.

Ferry range is more useful. Combat radius is generally considered 40% of ferry range.

With 2200 km ferry range lca can easily have combat radius of 900 km . However it will be around 500km for strike mission with heavy loads.

Mwf will have ranges equivalent to rafale and much better than mirage since f414 is way more fuel efficient than old m53.

So is Python as MR/SRAAM completely off the table for Tejas now?..View attachment 52669

Duel color maws are already developed many years ago with the help on Israel and already integrated to some of the sukhoi 30 MKIs .

Russians have objected to this modification so it is not integrated to all of the sukhoi 30 MKIs

Dual Colour Missile Approach Warning System (DCMAWS) for Fighter Aircraft | Defence Research and Development Organisation - DRDO, Ministry of Defence, Government of India

Dual Colour MAWS system operates in the mid IR band for identifying the approaching missiles of all generations. The spectral information of two colors is used to discriminate efficiently between sunlight reflections, background radiation and the radiation from the missile.

But it's still a standard figure. And the 500km on was a minimum value was quoted from here; http://delhidefencereview.com/2017/...s-a-superior-option-for-the-indian-air-force/

I'm trying to avoid any guesswork as much as possible.

Mwf will have ranges equivalent to rafale and much better than mirage since f414 is way more fuel efficient than old m53.

Due to lack of data on MWF, the 1500km combat range (not sure if on internal fuel alone) of Mirage-2000 was considered as a minimum possible.

I concure it could be around 1,500 KM atmost, 1,600 KM at limit's beyond that's is just wild guess.

It's ok. I don't have any issue with it.
Just that your own figure is consistent for mwf but not for mk1.

For mwf ferry range 3500 km so combat radius 40% of that == 1400km+ . Perfect.

And for mk1 ferry range of 2200km so combat radius should be 40% of that == 880km.
Also gripen c/d claims 800km combat radius.

That will remove inconsistency from your data. That's all.

About mwf range something to think about.

Rafale has 4700 kg internal fuel and 2 m88 engine .
Sipping it together. == 2350 kg per m88 fuel.

Mwf will have 3300kg for 1 f414.

Now m88 is slightly more fuel efficient than f414 ( and much less thrust ) still mwf has far more fuel per engine than rafale. Almost 45% more. A full 1 ton more fuel per engine!!

That gives us a hint how far mwf can reach for a normal mission load!!

Please also look at weight carried per engine. At MTOW, 1 F414 will be carrying 17.5 tonnes vs 1 M88 carrying around 12.25 tonnes.

 

[Raj Malhotra]

LCA MKI range is more than Jaguar.

LCA MK2 range is more than Mirage 2000

 

[ARVION]

Yes.

 

[IndianHawk]

That affects thrust to weight ratio more and affects maneuverability. But yes it will also affect range.
Still adjusted for all these factors mwf should meet rafale range on internal fuel.

Supersonic drop tank of 450 ltr is cleared for trial....
But not tested yet ,will update you...

Ok, so the supersonic one at Aero India 2019 is only 450lt & the new 725 lt one is subsonic?..

can u post all the fuel tanks of tejas with capacity.
