And here's a picture that suites the name Tejas (one with a Halo/corona, aka a star)

In the video posted by Rahulrds1,
with 6G Fcs clearance ,
LCA takes 20 seconds to complete a vertical loop at sea level.

to do that what would have been it's top speed?, and how will it help in determine the STR ?
Aeronautical gurus can now compare it to other fighters .

Also while LEVCONS of LCA can't be controlled by FCs to increase STR, their primary role of increasing the lift will automatically improve STR in all flight regimes.
Higher lift forces generated by LEVCONS always result in tighter turns.

Karthik's post from BR.



I pointed this out early on when someone here asked about the difference in operation between PAKFA's LERX and the LCA's LEVCONs.

Karthik's post clearly states that there is no choking of air intake during high alpha said to him by none other than the test pilot
Cmde Jaydeep Maolankar, veteran Test Pilot of the Tejas program .

Also for all the higher thrust the MK-2 will have just 10 mm increase in air intake which won't even be visible to naked eye.

So all comments that the air intake is badly designed and it is choking the fighter at critical high alpha is not based on any credible sources and just people's own views, and credible sources are in fact saying exactly the opposite.

F-414 was primarily Navy requirement.

Initially the IAF was fine with the F-404 IN 20. So there is no under power issues as you have been posting here.


These are the words of the veteran naval test pilot and N LCA project leaders,

LCA has already crossed AOA of 22 and may go a few degrees further is the words of the test pilot. They also said it is the best handler,

And even in the AERO INDIA 2013 it was not pushed to it's limits,

When asked about STRs and ITRs , he said ," it is enough , let me put it that way"

And note the wry comments regarding brochuritis infection(cutting and pasting different specs of different fighters with out ever thinking whether they can be achieved by a single airframe) of the services jokingly passed on by the veteran test pilot.

Also take note of his disparaging comments about DDM and all the bullshit spewn by them.

Tejas warms up for spitfire Iron Fist demo at Jaisalmer
Tarmak007 -- A bold blog on Indian defence

Bangalore: The next stop for India's combat fighter Tejas is Jaisalmer. After completing its duties at the just-concluded air show here, the aerospace masters at Hindustan Aeronautics Ltd (HAL) and Aeronautical Development Agency (ADA) are gearing up for the next big show – Iron Fist. Tipped as the mother of all fire power demonstration of the Indian Air Force (IAF), Iron Fist will be held from February 15 in the Pokhran and Chandan firing ranges, near Jaisalmer.
The participation of Tejas was confirmed to the media by the IAF boss Air Chief Marshal NA K Borwne during Aero India-2013. Sources now tell Express that at Iron Fist, Tejas will show the indigenous combat strength to Indian and international audiences for the first time. "This is the first time the IAF extended an invitation to HAL-ADA for Tejas' participation," sources said.
Three Tejas variants from its test flight-line are being readied in Bangalore for IAF's spitfire show. Tejas is also expected to fire a Russian R-73 missile in addition to dropping a LGB (laser-guided bomb). "Only one aircraft will eventually take-off for the fire display and the remaining two will be on a hot stand-by," sources said.
The HAL-ADA contingent, with a mission to prepare the aircraft, assess the flight analysis, collect the data collection and address any snags, are expected to leave Bangalore in the next couple of days. "We intent to achieve 100 per cent success during the fire power demonstration. In addition, it will also give Tejas an international recognition. For the first time it will be a day and night exercise, gauging the readiness and technological capabilities of IAF assets, of which many have undergone upgrades," sources said.
President Pranab Mukherjee will be at the range to get an upclose of the prestigious exercise, which will conclude on February 23.

However, when time comes for air dominance, some other ingredients like thrust to weight ratio and wing loading tend to regulate the sky.

this is the statement of TYPHOON test pilot when comparing it to F-35 , some guy here once famously wrote that low wing loading is related to passenger aircraft,can update himself.

So the lowest wing loading of TEJAS is there for a purpose , not to bleed energy as some bleeding heart experts tom tom, but for superior close combat performance enabling higher lift forces from low wing loading airframe for better instantaneous turn rate to dodge missiles.

LCA has transformed into more matured platform now and out test pilots are seemed to operating it with more ease in recent air show.... Path for LCA Mk2 is looking great.

Re: ADA Light Combat Aircraft Tejas

Isn't it from the program DRDO inside out ? Do you have the complete episode? I coundn't find anywhere.

It has no audio

Nope just found it on Utube...

Wing Commander (retd.) P.K. Raveendran, group director (flight test) of the National Flight Test Centre that test-flies the LCA, during a chat at the recent Aero India 2013 at Bangalore, said weapon integration on LCA did not pose a challenge, given the aircraft's modular avionics, open architecture and other anti-obsolescence features. "Adding a new weapon on the LCA is easy, as we know everything about the aircraft. It is entirely ours. It facilitates you to plug a new system in without hassles," he said.

Futuristic thinking at the time of design, he said, had taken care of issues such as weapon suite change, upgrade of avionics, effortless maintenance, and reduction of turnaround time. "While its aerodynamics is almost plateaued, you are free to change the weapons and avionics. This is what gives an edge to the platform."

Separately, it is learnt that handling flight of the LCA by the Air Force pilots will soon begin. "Once the aircraft is certified for induction, it will get detached from the umbilical. It will then become an Air Force fighter," said an official of the Aeronautical Development Agency (ADA), which designed and developed the aircraft.

Then why are people saying it's internal layout is a mess?

Automated Take-Off From Aircraft Carriers For India's Naval Light Combat Aircraft [LCA-Navy]

Trials to evaluate an 'Automatic Ramp Take-Off' system would be carried out shortly at the Shore-Based Test Facility [SBTF], making it, perhaps, the first ski-jump aircraft in the world with this feature.

If developments go according to plan, then Indian Navy aviators, flying the Naval version of the Light Combat Aircraft [LCA Navy], from Aircraft Carriers would have to do virtually nothing during take-off. Efforts are on to incorporate this critical phase of the flight into the aircraft's control laws itself. What it essentially means that computers, on-board the aircraft, running the software developed for its Fly-by-wire system, would be powerful & intelligent enough to propel the plane from Carrier into the air, without much human involvement. This was announced by Mr. Shyam Chetty, of the National Aerospace Laboratories, who is heading the team developing the control laws for the Light Combat Aircraft [LCA] Tejas & the LCA Navy.

Management of aircraft fleet operation from Aircraft Carriers, in the middle of the ocean, are considered to be some of the most difficult tasks, set to exacting standards. Take-off & landing these aircrafts on such a floating platform requiring immense skills & concentration for its execution. Building up a pilot's ability to perform these tasks requires one to undergo an extensive & expensive training regime. Despite such measures, human beings, that the pilots currently are, would still be prone to committing errors, which in their case could result in causing losses amounting to many millions of dollars, all unravelling in the blink of an eye. This is especially true while returning to land on the Carrier after performing many hours of a mission. Fatigue, coupled with the vagaries of maritime environment, impose enormous demands on pilots who are required to land their aircrafts on a deck that has often been described to appear no bigger than a "postage stamp". The challenges of taking-off from such a platform, as seen from the slide below, are just as unforgiving.

Therefore, any system that can safely remove the uncertainties of human decision-making & reactions from the equation while carrying out such critical & demanding operations & introduce predictability, would help make the process that much more robust & secure, in addition to simplifying required training. Developing a practical system for automated take-offs and landings are also crucial for subsequent development of Unmanned Aerial Vehicles [UAV], operating with higher levels of autonomy. The U.S. Navy's catapult-launched F/A-18 'Super Hornet' aircraft has successfully implemented the such pilot-independent take-offs. It has also demonstrated ability to land on the deck unassisted with the the Automatic Carrier Landing System [ACLS], a feature that was present in the Soviet Yakovlev Yak-38 fighter too. As part of the 'B' variant F-35 Joint Strike Fighter [JSF] development programme, British Defence Evaluation and Research Agency [DERA], & its successor QinetiQ, had carried out successful hands-free vertical landing of a modified Harrier aircraft. Haven't come across any news confirming whether the F-35B's take-off too would be hands-free. Neither has there been any reports to suggest the Chinese are implementing such a system in their recently unveiled J-15 carrier-borne fighter. Thus, from all accounts, when implemented on production aircrafts, LCA Navy would be the first ski-jump aircraft in the world with such a hands-off take-off feature incorporated.

An interesting talk he delivered where he spoke of the immense challenges faced in designing the control laws for the Tejas, an endeavour being undertaken for the very first time in the country.

IAF to deomstrate gears up for Iorn First at Pokhran

Tarmak007 -- A bold blog on Indian defence: IAF to deomstrate gears up for Iorn First at Pokhran



February 22, 2013 would witness the Indian Air Force demonstrate its operational capabilities by day, dusk and night at the sprawling facility of the Pokharan Range, the largest air –to-ground weapons firing range fortraining in delivery of heavy armament, near Jaisalmer, in the arid Rajasthan Sector in an Exercise named – The Iron Fist.

Showcasing more than 30 types of platforms and Weapons Systems amounting to a participation of over200 aircraft, this Fire Power Display will demonstrate the day and night employability of air power by frontline fighter aircraft of the IAF including - Su-30 MKI, Mirage-2000, Jaguar, MiG-21,MiG-27, MiG-29 and Hawks. The transport aircraft would include – C130J, AN-32, Embraer and IL-76, while Mi-8, Mi-17 V5, Mi-17 1Vand Mi-35 Attack Helicopters will constitute the Rotary Wing ingredients.

Being a display of armament delivery skills by pilots at the end of their training year, the exercise also aids commanders and planners to gain better insight into the potentialand deployment capabilities of aerialweapons.

The IAF would also be showcasing, for the first time, its Surface to Air Missile Systems and its latest aircraftPilatus PC-7 Mk II. The events at - Iron Fist intend to display various aspects of Fire Power like- Air Defence Operations, Counter Surface Force Operations, Urban Warfare andCombat Search Rescue Operations.

Light Combat Aircraft and Light Combat Helicopter, two of the most prestigious indigenous projects would also form a part of the display. In addition, IAF's Parajumping Team, Akash Ganga, IAF's Air Warrior Drill Team and Air Warrior Symphony Orchestra would also perform.

Aimed at providing the nation the reassurance that the IAF will deliver whenever called upon, a demonstration of this magnitude is being carried out for the first time by day, dusk and night. Very few air forces in the world can achieve this feat.
