ADA Tejas (LCA) News and Discussions

[aditya10r]

Not sure the date of publication but from official source ..

This stat is also slap in the face of chotyas who call tejas imported fighter and demand for an imported fighter.

Take this assholes.

 

[patriots]

ya 75%....if we can have our own engine. then it will be go upto.....90%

Not to forget the RADAR.

@TPFscopes if I'm not wrong the IAF uses Alpha 300 helmet right
Is there any effort to develop an indigenous one yet?

yup, but only for Hawk pilots.

Quick question

What exactly is sensor fusion? Is the feature available on Tejas mk1/ Tejas mk1A?

Quick question

What exactly is sensor fusion? Is the feature available on Tejas mk1/ Tejas mk1A?

There are many sensors on a modern jet(like aesa radar, irst, Electro-Optical Targeting System etc ) ...... Sensor fusion is software that intelligently combines data from several sensors for the purpose of improving application or system performance. Combining data from multiple sensors corrects for the deficiencies of the individual sensors to calculate accurate position and orientation information.
It is just a software so it can be included in Tejas...... But Tejas don't have irst and eots so no need of sensor fusion.

@rohit b3 to add to @airtel's point, from the pilots' perspective without sensor fusion information from each sensor will be displayed on a different screen/dial in the cockpit. So the pilot has to almost simultaneously keep track of many different nodes of information severely increasing the pilot's workload.
What sensor fusion also does is that it compiles all the information from the different sensors and shows it on the single/dual screen. Since the pilot now has to keep track of only one or two nodes of information, his workload is decreased and he can put more attention to other tasks such maneuvering or engaging the enemy.

Thanks guys!
So cant sensor fusion be achieved among the other sensors apart from IRST and EOTS?
Tejas pilots claim that all the information required for them are easily available on the MFDs. Isnt that sensor fusion?

Sensor fusion can be applied to any electronic sensors on a platform.
However not all aircraft are sensor heavy. So when designing a plane the designers need to make a choice whether sensor fusion adds capability justifying the increase in unit cost.

The LCA Tejas does have limited sensor fusion but it does not have pure sensor fusion. The only aircraft today which comes the closest to having pure sensor fusion is the F-35.

Tejas cockpit - Limited sensor fusion

F35 cockpit - complete sensor fusion (once 100% ready)

Also read the link below to get an idea of what sensor fusion is doing on a sensor heavy platform like the Rafale

This is the cockpit designed by HALBIT (HAL ELBIT JV) and IAF is insisting to have similar cockpit on TEJAS mk2

by the way this is new Tejas cockpit .

A quick question

Both (HAL & ELBIT) designed this cockpit for which ac.

 

[pruthvi24]

is it really necessary to have foreign single engine jet like f-16 or SAAB gripen when we have Teajs why can't we just do Mass Production of Tejas which is as good as if not better than f-16 and why is it taking this long for Tejas FOC

 

[TPFscopes]

A quick question

It was for AMCA and also designing a cockpit for Tejas Mk2

 

[NightRider]

No you are absolutely right. Tejas is not suited for CAS operation. It is well suited for interceptor role.

But interception will be the role of air defence missiles.

Thanks! So im guessing aircrafts like Su-30MKI or Su-35 also have limited sensor fusion?
And according to your last link, does the existing Rafale variants have it, ? or is it for the future variants?

Foreign fighters are absolutely not necessary. But every effort is being made to kill the LCA project both in the IAF and the Navy. Apparently the Foreign Fighter jet lobbies are pretty powerful!
But if you ask me, even as of today no official RFI or tender for any import has been issued by the Govt. It has been all talks and use of the Paid media.
And looking at the past, from the day tender is issued to the day the first aircraft is delivered, it takes over 10 years!
The MMRCA(Rafale deal) began around 2007 and ended up with just 36 Rafales, first of which will be delivered in 2019 . - 12 years.
The Attack Helicopter tender(Apache deal) was opened in 2008 and the first Apache will be delivered in 2019 as well - 11 Years!
And these are relatively small deals.
Even if the tender for a 20Bil$ Deal to import F-16/Gripen opens next year, the first aircraft wont be delivered before 2028.
Dont think its gonna happen.
We are gonna mass produce the Tejas and have over 200 of that.

Yes all current 4th Gen. aircraft have limited sensor fusion.

The current Rafale models do boast of the features listed in the webpage. They might add more features to the new Rafale F4 models which are coming tentatively by 2023 but what exactly those features will be regarding sensor fusion is not known yet.
