LCA TEJAS MK1 & MK1A: News and Discussion

[IndianHawk]

It seems Tejas is limited to 1.6M right now .
While naval mk1 prototypes are limited to 1.4 M.

But that is not something set in stone because Tejas is also limited to 8g and 24° attack angle and yet lsp aircraft have been pushed by test pilots to 8.5g and 26° aoa.

So with more testing these performance envelope will be opened for all in service aircraft. Speed may be similar case.

 

[IndianHawk]

Yeah... Its HVT's words against yours.

I think he confused naval mk1 top speed with regular mk1.

 

[Armand2REP]

Yeah... Its HVT's words against yours.

That is the fastest it has been tested at, there is nothing to argue.

 

[Bleh]

That is the fastest it has been tested at, there is nothing to argue.

Who's arguing? HVT says 1.6M regarding Mark1 FOC first flight.
Nothing you (or anybody) say has any relevance against his words.

Nope Delhi defense review article on mk1 clearly mention that in service aircrafts are limited to 1.6M.

"In service aircraft are certified to fly from -3.5 to +8.0 G up to an altitude of 50,000 feet, a top speed of Mach 1.6, and an angle of attack (AoA) of up to 24 degrees. The test pilots have stretched the prototypes even further, up to 8.5 Gs, and 26 degrees AoA. At the 2016 Bahrain Air Show, the Mk1 had even demonstrated a low speed pass at 110 knots. The FCS has now been updated to lower the minimum speed to 100 knots, at which point auto recovery is initiated. The 2016 demonstration at Bahrain also showcased another important feature: Following the above-mentioned low speed pass the aircraft immediately proceeded to accomplish a vertical climb. "

So in service aircrafts are already hitting 1.6M.

The highest reported speed that it was tested at was Mach 1.4 as of the end of 2019. What the aircraft is capable of and what it has been tested at are two different things until it has passed certification to do that speed. Rafale can blow past Mach 2 but it is not certified to sustain that speed.

You're not ot making any case here by repeating the same words again. Better to go read the tweet.

 

[patriots]

The top speed it has been tested at is Mach 1.4 but that is with underpowered F404 engines.

Already 1.6mach achieved.....
We are debating on 1.8 mach

Bdw hal website says max speed 1.6m
Though my heart was broken
I believed Tejas ioc ,naval Tejas is 1.6 mach
And Tejas foc speed will be 1.8 mach

The test parameters are classified until after the results are authorised for release, not before.

Sir do u have info on derby bvr range

 

[Armand2REP]

Sir do u have info on derby bvr range

Rafael says Derby ER is twice the range which makes the original Derby 50km.

 

[Bleh]

The test parameters are classified until after the results are authorised for release, not before.

And until that is done to confirm otherwise, his words carry infinitely more weight than yours. No offence meant, it is just as true about me or anyone else here, unless BRF Indranil or AK has a profile here.

If he is truly privy to privileged information he wouldn't be spreading it around social media like a honeypot traitor.

 

[patriots]

Derby er has 100+ range
If it is 120 then derby range 60
A recent report says derby has range of 60 km
So asked you

He only says what is already in open media
Hal official site says Tejas has speed of 1.6m

Watch at 0.75X speed.

Here's How the New HAL-Made FOC-Standard Tejas is Better Than the Current IAF's IOC Fighter Jet
Hindustan Aeronautics Limited (HAL) recently conducted maiden test flight of its Light Combat Aircraft Tejas in Final Operational Clearance-standard. The jet bearing number SP-21 was piloted by Air Cmde. K A Muthana (Retd), Chief Test Flying (Fixed Wing) of HAL. The aircraft took-off from HAL Airport and was airborne for 40 minutes.

"HAL achieved the momentous feat within a record time of 12 months after release of Drawing Applicability List (DAL) and SOP (Standard Operating Procedure) by CEMILAC", the statement said.

The FOC Tejas is said to be more advanced and was developed with improvements suggested after inducting LCA IOC in IAF. "It imbibes a lot of manufacturing improvements which were based on the operational feedback of LCA IOC (Initial Operational Clearance) fleet with IAF", HAL said.


IAF will soon induct 16 FOC-Standard Tejas for its 18 Flying Bullets squadron based out of Sulur, where the first Tejas squadron 45 Flying Daggers was established, consisting 16 IOC Tejas.

Once all the 16 FOC Tejas are delivered, HAL will covert the IOC Tejas to Final Operational Clearance-standard and will then move to manufacture the Tejas MkI.


Here's how the FOC Tejas is better than IOC Tejas and what are the changes in the new fighter jet-

Range ::

The biggest criticism of the LCA Tejas IOC version was its limited range and fuel carrying capacity. The IOC Tejas currently carries two fixed tanks of 1,200 and 800 litre capacity. The FOC-Standard Tejas now gets an additional tank with 725-litre capacity installed in the central line, just at the centre of fuselage.


Mid-Air Refueling ::

To enhance the range further, the FOC Tejas further gets a mid-air refueling probe for the very first time, which means, it can fly for longer missions without worrying much about the fuel. This however, will increase the radar cross section of the indigenous jet, which otherwise has a small radar signature thanks to its compact design.


Auto Cannon ::

The FOC Tejas carries a Gsh-23 auto cannon with twin barrel 23 mm gun. The auto cannon now has better software and has been tested on ground. Soon, the cannon will be tested for its air combat capabilities too.


BVR Missiles ::

The LCA FOC Tejas will also carry the Astra BVR missiles (Beyond Visual Range) in future. Astra is home-made BVR air-to-air missile with 110 km range. Currently Tejas carries Derby BVR sourced from Israel.


Agility ::

The FOC Tejas will have a better maneuverability and agility that will help Tejas to touch 8G force at lower speed, increasing its flying envelope. Tejas can maneuver from -3G to 8G. To achieve such agility, changes have been made to the mechanical system including the flaps. This will also help Tejas to save itself from incoming missiles by quickly pulling a 8G move without stalling mid-air.

What about Aesa radar ? Will FOC have it ?
