Fuel transfer from IL-78 to #Tejas is a reality now. After dry contact trials couple of days back, 1st ever air-to-air refuelling has undertaken today. "It just happened," says a source. Congratulations to #IAF, HAL, ADA & NFTC teams.

Unlikely.

PV-6 is one of the two trainer prototypes heavily engaged in FOC flight testing of the Trainer version and training IAF pilots of 45 and 18th squadron.

Adding an engine testing function will seriously encumber the first two roles.

Logically doesnt add up. What is the source of your information?

Well congratulations to all of you and me.
We should be celebrating if this is now confirmed via two sources that fuel was transferred.
Well done to all of us again.

Wonderful stuff. It must have been an interesting analysis to update the FBW for fuel transfer, with CG shifting all over the place and that too in mid air .
Top notch stuff. In another year, it will be flying with a AESA radar. AESA, top notch BVR, FBW, Refuelling, Indian, Israel, Russian weapons, top notch engine.

Compare this to the jokers on the western border, who tom tom a plane, which have no clear video of ever firing a BVR. :rotfl:

123 is already for MK1+MK1A. Then there will be MK2 orders of atleast 100/123. Overall close to 250. That is equal to SU-30 orders.

IAF has committed. It is now for HAL to buckle up.

Another point that is not obvious, LCA has a perfect update plan going in. MK1 FOC, MK1A, MK2 all planned up with incremental capability added in each tranche. No other jet in IAF inventory has such a future planned up. The closest may be Jags with their Darin program.

:D :D Gladdens the Jingo heart. In Tejas, we have an Indian solution to Indian problems. Now if only the following happened:
  1. Quick ASEA Integration
  2. Get the Kaveri onboard and further reduce scope of sanctions
  3. HAL stops getting their 'chaddis' in a twist and ramp up production to 16 birds a year
  4. Assured govt orders as the IAF gets accustomed and develop tactics
  5. Exports to Africa/ Lat-Am
  6. A dorsal mounted death ray

Indeed Saar Indeed.
However even if they produce a 4K video of fuel transfer and BVR firing, it is nothing but the equivalent of us producing Su-30 MKIs taking fuel from IL-78.
Now they of course believe its a Paki plane, let them continue to believe so.
Its as Paki as the Su-30 MKI or Mig-21 is an Indian plane.

With Tejas

^^ they are doing it quite quickly now.. I thought moving to actually transferring of fuel after dry contact will take months.. but it all happened so quickly.
Congratulations :D

Excellent news! Kudos to the team and to Wing Commander Siddharth Singh who flew LSP-8.

https://twitter.com/livefist/status/1039097202537373696 ---> Big step for India’s LCA Tejas fighter as it takes fuel mid-air for the first time. Congratulations to the flight test team! This flight piloted by Wing Commander Siddharth Singh at 9:30 a.m. today from Gwalior.

Tejas completes key midair refueling trial
BENGALURU: Just days after the successful ‘dry contact’ with the Indian Air Force’s (IAF) IL-78 midair tanker aircraft, Light Combat Aircraft (LCA) Tejas on Monday completed the first midair refueling trial, which is one of the things required for the aircraft to obtain the Final Operational Clearance (FOC) which has missed several deadlines already.

On September 4 and 6, the Tejas had made a dry contact with the IL-78 exhibiting the plane’s ability to dock the refueling probe. On Monday, the Tejas Limited Series Production aircraft number eight (Tejas LSP-8) “successfully completed the Wet (actual) engagement by transferring 1,900 kg fuel from IL-78 midair refueling tanker.”


The refueling was carried out at an altitude of 20,000 ft. The aircraft speed was 270 knots and all the internal tanks and drop tanks were refueled. A few days ago, the successful dry docking of aerial refueling probe with mother tanker was carried out on September 4 and 6, 2018,” HAL, the manufacturer of the fighter said in a statement.

Piloted by Wing Commander Siddharth Singh of the National Flight Test Centre (NFTC), the refueling took place at about 9.30am with designers from HAL and Aeronautical Development Agency — which designed and developed Tejas — closely monitoring the system parameters from the ground station at Gwalior.

“The performance of aircraft systems (mainly Fuel & Flight controls systems) during the trial were in line with the design requirements and closely matched with the results of extensive ground tests of air-to-air refueling system,” the statement read.

With this, India joins the elite group of countries who have developed the Air-to-Air (AAR) system for military class of aircraft, HAL’s new CMD R Madhavan said in his first statement to the media since taking charge earlier this month.

On September 4 and 6, the Tejas had made a dry contact
so this was atleast the 3rd sortie out of 10 that are required for qualification.

Is it that drop tanks can also be refuelled? Can anyone confirm this.

This is really a big deal. A/C can take off with empty tanks (for optimal take off performance), get refuelled in the air. Or they can fly large distances - before getting to the FBA, can fill their tanks and keep their internal fuel available for combat/high maneuverability situations.

Sorry to bother you, should have posed the question better. I did not know that air to air refuelling can also fill the drop tanks. Until now I thought it was only internal fuel tanks, that is why I asked if someone can confirm that drop tanks can also be filled during air to air refuelling. I got it now.

This is massive, Tejas with internal fuel and 3 or 1 drop tank(s) then all get refill by A2A refueling. It will give Tejas unprecedented capability in terms of CAP and deep strike.

Yes. Whether during ground fueling or mid air refuelling, the external fuel tanks are loaded centrally through the fuel management system.

So actually there were two contacts.

The tankers are different too. One is RK3451 and other is RK3452 :wink:

Unless different tankers were used on different days

They did two days of dry runs, before the wet refuel
The starboard one is the dry run
The port one is the actual fuel transfer

Once LCA with the probe get inducted, it will become the most efficient peace time CAP jet we have. All Mig-21 peace time, jobs on the border will be taken over.

Single engine, F404 Engine with in flight refuel. No other jet in IAF inventory comes close to the fuel efficiency.

There might some niggles about STR/ITR etc, however our endeavor to develop a 4+ Gen with Composite, FBW, BVR, LDP, Refuelling and ability to integrated with weapons of our choice has come to fruition.

Our people have delivered what they promised (may be delayed a bit by 2 years). This is for all the people who said we should have created a simple Mig21 knock off like the JokerFighter-17.

So I say promise the sky, we might just achieve it. :D

One tanker on duty, another for backup saar. So there were two in the air on all days.

One question, saar.

is the AA refuelling system locally developed and qualified ?? or

has an already existing AA refuelling kit with the probe been integrated and then the system qualified on the LCA by flight test??

Maybe we could look at our short legged MiGs too and maybe give them such a AAR capability to possibly extend their utility and operational envelope??

Great news! What's left for FOC?

1. BVR [In progress, Derby test fired 2018]
2. In-Flight Refueling [In progress, Wet test completed 2018]
3. Gun Trials [In progress, Ground firing completed 2015?]

Rest everything is completed AFAIK. Anything I'm missing?

Read somewhere, it is a Cobham kit( probe) . I don't know how much of the entire fueling setup is local. HAL may have gained experience on Hawk Advanced project.

There are Mig21s with probes. So countries have done it. Not sure how much IAF is interested in such a option.

great to hear...

Chetak our limitation is not fitting probes to fighters....we have 300+ fighters already with probe (su30, jags, m2k, mig29upg, tejas), but the fact we only have 6 refuelers with limited fuel.

these 6 will be heavily tasked to support the Phalcons in a war situation.

we need the 90 t fuel of the A330 MRTT vs the 40t of the Midas to refuel the hungry heavies and support CAP units all over.

Once again I say, for every squadron of fighters we need at least one AWACS and on refueler.

Buy additional fighters only alongwith these necessities.
