Tejas - Feature - First flight by Air Marshal Philip Rajkumar (Retd)

The day of the first flight of TD-1 vividly described by Air Marshal PHILIP RAJKUMAR. Nice read.

After Kothi had flown the first six flights, I sent in his nomination for the prestigious Iven Kinchloe Award to the Society of Experimental Test Pilots (SETP) in the USA. The SETP gives this award every year for the most significant achievement in experimental test flying during the year under consideration.

Very few in India seemed to have realized the significance of the achievement of safely flying a prototype with so many new technologies on board. However, the SETP awards committee which consisted of a group of very experienced test pilots who had seen many programmes worldwide thought differently and had no hesitation in giving the Iven Kinchloe Award for the year 2001 to Rajiv Kothiyal. I was very happy that Team LCA's monumental effort had. been recognized by a bunch of hard-nosed professionals.
No Indian test pilot has ever received this award in the past. Without exaggeration, the Iven Kinchloe Award can be called the 'Oscar' for experimental test flying. In the finest traditions of the IAF, Wg. Cdr. Rajiv Kothiyal had truly touched the skies with glory.

Smashing looking kotial with fernandez, kota harinarayana and abdul kalam and high ranking IAF official.The picture may have been taken after the first flight of tejas, though I am not sure.

Tejas - History - Timeline
the official historical milestones of tejas program.

2009
22nd January - Tejas completed 1000 flights.

October - PV-3 and LSP-2 completed air-to-ground weapons delivery trials.

26th November - Two seater (Trainer) version of Tejas (PV-5) made its maiden flight on 26 Nov 09.

7th December - Tejas speed envelope expanded to 1350 km/h (CAS) while performing flight flutter test in a dive to near sea level. These tests were conducted at INS Hansa, Goa.

How many docterate holders in engine tech were there in the MMRCA selection team of IAF?

then why did sukhoi fail to honor the commitment of twin seat version wich was asked by IAF?
Then why did the IAF reduced the number of fgfa orders?

It is carlo kopp who has criticized sukhoi for the same mistake read the points no -9 and 10 in his report,
in the post quoted in the same pakfa thread.

You have said that lca has been grounded with out a flight for 6 months.

Even if you have any knowledge regarding what was achieved in the past thousands of flight tests in the past 10 years , I can discuss something with you.

Since you dont know anything about these mundane thing ,dont jump in the middle of the thread and post stupid things.

first know what is being discussed before jumping in the middle of a debate.

First time you said that your friend "forgets some social niceties while making posts".
I ask you to take the dictionary and see the meaning for the word "BARBARIANS". And make your own conclusions.

Why are you changing topics to MMRCA ?

I am not the one saying LCA is grounded. I am saying that in july LCA had made 1941 flights, now it has made 1944. But I guess that means grounded, so yeah, 4 months.

Please don't get impression that I am here to debate with you, because you are impossible to debate with.

 

[ersakthivel]

Why are you changing topics to MMRCA idiot?

Why did you only quote parts of Carlo Kopp's report which you liked, didn't you read the part where he said PAK FA has high potential to become VLO aircraft?
So much for your serpentine intakes and the other crap you were talking about.

I am not the one saying LCA is grounded. I am saying that in july LCA had made 1941 flights, now it has made 1944. But I guess that means grounded, so yeah, 4 months.

i know as much as you know about why there were no test flights.what is LSp-7 doing?
Last heard LSP-7 is about to be handed over to IAF for participation in an upcomming excercise in feb 2013.
and what happened to LSP-6?
Again post what you know about what happened in those 1941 flights

Please don't get impression that I am here to debate with you, because you are impossible to debate with. I am here to tell you what every guy who has ever debated with you has told you, "You are an idiot."

They are all guys from official body called IRI---- international ranters inc

Lastly P2p is not my friend, I am not taking his side or anything. I am just fed up with you spreading all over this thread. At first I thought you would stop, but it has been months now. Please stop.

I thought this was not some chinese censored website( WHERE WE ALL HAVE TO TOE THE OFFICIAL LINE set by our visionary senior leaders) instead a bloody indian democratic site where all colorful charecters like you and me and your friend (or not so much of a friend )can have a debate like the BRETHREN COURT in the "PIRATES OF THE CARRIBEAN".

In this forum me and you had 3 conversations .

everytime you came in to defend somebody else's point of view against me without any authentic source.

Every time I just steered the conversation to a polite end and finished it.

But you are once again picking on me.WHY?

Please forgive me as I am not upto your standard of debate and lets end our discussion here .

sketch posted by kunal

And all 7 pylons loaded with munitions and drop tanks according to the sketch.
the 3X 1200 2x800 kg pylons kg pylons can be configured with multi ejector rack fitted with long range or medium range BVr and WVR missiles as much as their weight support level of 1200 kg in each pylon.So weapon load out for air to air mission is quite decent.

So there wont be any limit of only 4 long range BVrs only limit like that.Since mk-2 is going to have a very high TWR excess drag from multi ejector racks wont matter much .
So for an air to air mission withoutdrop tanks tejas has 7 pylons for air to air missiles BVRs and WVRs ,besides one pylon for the pod rated at 200kg.

 

[ersakthivel]

With increased internal fuel of around 3000 kgs in mk-2, all 7 pylons in the above picture can be free to carry missiles and bombs even in long range sorties making it a very potent fighter as there will be no need for external fuel tanks.

Retiring squadrons by 2022:
5 x MiG-21 M/MF
2 x MiG-21Bis
6 x MiG-21 Bison
3.5 x MiG-27 ML
2 x MiG-27 UPG
Total (retiring 2022): 18.5 squadrons

Current Squadrons (2010) still in place by 2022:
3 x MiG-29UPG
3 x Mirage 2000UPG
6 x Sukhoi-30 MKI
5 x Jaguar IS
1 x Jaguar IM
Total (remaining 2022): 18 squadrons
Note: All listed here, except MKI, will be retiring between 2022 and 2030.

Planned Squadrons in place by 2022:
2 x LCA Mk.1
5 x LCA Mk.2
9 x Sukhoi-30 MKI
7 x MRCA
2 x PAK-FA/FGFA
Total (induction 2022): 25 squadrons

This means in 2022:
Total (remaining + induction): 18 + 25 = 43 squadrons in 2022

The blue boxes looks like new internal fuel tanks that have been added because they have been highlighted with the same color denoting the same object type.

There are two tanks in the side just behind the pilot , on each side of the front fueslage, just in front of the intakes

There is a tank on top of the spine and wing tanks, placed on the spine with wings on the sides.

l in all approx extra internal fuel, that in addition to the existing tanks, takes it close to 2300 + 400 /600 +100 , ie around 2800 to 3000kg total per my estimate.
So it comes to near 3000 kg of internal fuel.
That is close to the internal fuel of a M2K
The engine thrust will be way higher than mirage.
And empty weight of tejas mk-2 will be 1.5 ton less than the less empty weight of mirage-2000.

SO combat range and loitering time will be very high.

the Fuel Fraction will be better than that of the M2k, marginally. And the mirage always had excellent fuel fraction.


Now keep in mind that the 414 engine has a better SFC than the 404 IN20, and that the IN20 has a much better SFC than the M53 on the Mirage. so combat loitering time and range will be very good with way higher thrust to weight ratio.The empty weight may be around 7 tons if weight reduction target is achieved with more composites in the airframe

normal combat range will also go upto 1200-1500km as in Gripen NG or F-16 Block 50/60 range.

This one is better one ..

specs for mk-1 from aerindia-2011
Clean Take off weight - 9800 kg
Empty Weight - 6560 kg
External Stores - 3500 kg
G Limits - +9/-3.5 .

The empty weight compares very well to Gripen C/D Tejas has more wing area than grippen c/d with even lower wing loading should be noted here.

.
All eesss well!

Just to show how much effort goes into a designing one component like radome and it also gives insight into the technical parameters of LCA MMR

Tejas, little fighter with BIG punch? [Archive] - Key Publishing Ltd Aviation Forums

Some very interesting discussions regarding tejas's range

http://frontierindia.net/light-combat-aircraft-tejas-testing
An article by Air marshal Philip Rajkumar on the weight reduction excercise and the AOA tests reaching 23 degrees.
According to him it now weighs 6430 kgs -empty weight.
What is not clear is whether it includes flight testing equipment's weight or not?

LCA to be an advanced version of MiG 21: IAF chief

Asked if the present version of the aircraft could be called a fourth generation aircraft, as DRDO was claiming it to be, the IAF chief said with future developments, it could become one but was not so at the moment.

Explaining the parameters on which he called the LCA Mk II as MiG 21 + + aircraft, he said, "This means first in endurance, second in performance, third in load carrying, fourth is the number of weapons it can deliver. Fifth is the weight with which it can navigate with and the vintage of the aircraft or avionics and sixth is radar."

Asked to compare the aircraft with its contemporaries, Naik said it would be just short of Swedish Gripen NG single engine aircraft.

the F404-F2J3 that is being used in LSPs and PVs has thrust rating of only 18,300 pounds.

The LSP s are operating only at a restricted flight envelope of 85 percent on the thrust of 18,300 pounds from F404-F2J3 engine.

But the SPs (serial production) will operate on 100 percent fully opened flight envelope with 19000 pounds of thrust. from Ge-F404-IN20 engine.

So the Tejas in SP version will have much better specs than the LSps and PV versions which have lesser powered engines.

And mk-2 will have much higher thrust at 22000 pounds.

The option of 26000 pounds in EPE version is also available.

The F404-1N20 selected for initial tejas mk-1 has ------- 19,000 (LCA MK1)

Often it is said GE F414-INS6 ordered for LCA Mk2 is same as GE F414-EPE.
Thrust of GE F404 variants in pounds

F404-1N20 > 19,000 (LCA MK1)

F404-F2J3 = 18,300 (LCA-TD)--Running on the tech demos,prototype vehicles(PV),Limited series production (LSP) versions of tejas mk-1.

F404/RM12 = 18,100 (Gripen)

F404-402 = 17,700
F404-400 = 16,000

So with increase in engine thrusts tejas will mature into a potent fighter.
This was what ACM NAIK must be saying with his remarks , that it is now mig-21++
How this remark of mig-21 ++ was so effectively used to browbeat tejas.preposterous!!!!!!!!!!!!!!
If you take into account ACM naik's remarks in full detail, he actually says tejas is as good as any 4.5th gen with all the capabilities he detailed.
How howling dogs in the media kept on using this remark to beat it down again and again!!!!!!!!!!!!!!!!

Some more interesting discussion on tejas in another key publishing thread.going through threads like this will broaden the level of knowledge on tejas for every one.

looks like LCA is slowing occupying MiG-21's Bunkers......
