Try reloading guys. None of the pics are not visible of just the first ones?

Father of ‘Tejas’ World’s smartest Fighter plane of its class wows Nagpur Engineers

Nagpur.

Just as the shine and the gleam around ‘India made’ LAC Tejas is beginning to wear off as even Parliamentarians, including the PM, questioning DRDO about delays and cost escalations , the scientist who headed the Tejas project Dr. Kota Harinarayana was in Nagpur recently to attend the 18th National Seminar on Aerospace Structures held at VNIT recently.

Nagpur Today team had an exclusive interaction with this accomplished man who has achieved so much for India and found him as genial and good humored as he is talented.

Explaining the complexity of the LAC project, Dr. Harinarayana explained that it was a quantum leap for DRDO to design and manufacture this fighter plane which is leagues ahead of MIGs or other older generation fighter planes.

” Tejas is a fourth generation fighter plane; as state of Art and as sophisticated as any found in Western Europe, USA or any of the developed countries of the world. It is a manned fighter plance and born out of collaboration of NASA, Banglore with 300 Indian industries, 40 Research labs and 20 academic institutions working together for almost fifteen years. Never has such a broad based public-private collaboration happened on such a sensitive and high security project for the country. What’s more, our scientific and technology community achieved this despite US sanctions against us that were in place then.”

“We knew what we wanted, but we had no idea how to proceed – each element of the design, each raw material for the plane had to be designed from scratch. It had to be highly agile, light, able to achieve super sonic speeds and yet sturdy.”

How sophisticated Tejas is can be seen from the fact that it takes a millisecond ( 1/ 5th of a second) to react to a command and is therefore too fast for a human to control. (The fastest human reaction takes at least one second ). Thus humans had to design computers who could take over once human beings (pilots) determine the course of action for the plane. Such facts make Tejas the fasted and smartest fighter plane of its kind in the world today.

But this project that should be making Indians proud and enhance the reputation of our scientists’ world wide is coming under a harsh scrutiny now. Here are some of the problems plaguing it : The composite wings need redesigning. There are some unanticipated complexities faced in structural design too.

HAL – where Tejas is being manufactured – is found to be lacking in production facilities and skilled manpower. It was scheduled to make 8 aircrafts in one year, but has made only 4. Meanwhile, the Government has had to increase DRDO annual budgets for this and other such projects about ten times.

Unfazed by such criticism or looming budget problems Dr. Kota Harinarayana spoke about how one such mega project helps our technology and industry people come up with innovative products and process not manufactured in India before and that have a tremendous export potential.

A fall out of Tejas project is that it has lead to development of many sophisticated ‘byproducts’ that are today being exported by Indian companies to Israel, USA and Sweden, considered world leaders in such products.

And though HAL may be facing production problems Dr. Harinarayana is already planning new projects to use the technology developed for Defense in civil aviation and increase the areal connectivity of the country.

“Instead of these mamoth Boeings that carry 200+ passengers why not go in for smaller aircraft that will carry 20 passengers profitably – and also be used as cargo carriers? If this is made feasible we can have air connections between smaller Indian cities like Chandrapur, Wardha, Bilaspur etc. The airports required to land such planes can also be smaller and cheaper to make” the enthusiastic and visionary scientist pointed out.

There was kind of a hiatus in every activity in the last 3-4 years in our country, But the new Government will understand and appreciate the scope and potential of our work and encourage and facilitate us. Said Dr. Harinaryana. He is looking forward to 100% co operation from Modi and the new Defense Minister.

What do you mean bro ??

read the title of the thread , and than read my post

Every test conducting facility is available but on ground. When will that bird will fly in a sky any confirm time frame bachay say jawan ho gaye but lca nah urha :-X

Sir this bir has been flying for quite some time now. Not only that it did not have a single malfunction in it's entire flight time. That itself is a testament to the hard work the scientist have invested in this project.
FYI we just tested the naval variant too few days back from STB.

Try now bro.

ok, turns out the problem was my browser blocking an untrusted connection to Aeronautical Development Agency added an exception and works now.

Well then you must go through the thread posts. We all would like to see such things from your side too. Nothing beats technology p0rn. No matter where it come from.

The MMR radar is seen installed on the 'Hack' aircraft. This radar is being developed under the LCA 'Tejas' programme and has an intended detection range of 120 km vs a 2 sq.m target. The Hack is offered for other testing purposes as well

@Oscar @Chak Bamu Pakistani members are swarming in a wonderful thread,but I see no pro activeness by Mods here unlike in Pakistani thread.

 

[acetophenol]

that is not a jf-thuder thread or else i would have answer you .. but for long story short ,
all blk-1 will be upgraded to blk standards ,

your rudeness cant hide the reality , your so called Tejas is still in ground ...
our Jf-17 is not just flying but in blk-2 production .. ( off-topic )

its indeed that " what has LCA tejas given to indians " A BIG HEART ATTACK

Look bro, LCA Tejas is capable of doing everything a modern aircraft needs to do. It has completed 1000s of flights in the most diverse and challenging environments without any accidents, has delivered modern muntions (LGBs, Air to Air Missiles), has all critical cutting edge technologies (FBW,HMDS) etc. Tejas is not yet in the service because of the strict non compromising high demands of IAF.

LCA was not just a project to make an aircraft, but to grow an entire aviation ecosystem in the country, in which it was a success. The some of the fruits of the LCA program is what you see in this thread.

You just can't compare the development of Jf-17 with LCA, one is a JV and other is a own venture. However I request you to launch a separate thread highlighting Pakistan's contributions to the project.

The LCA's Multi-Mode radar jointly developed by the Centre for Airborne Systems (CABS), ADA and HAL is a coherent pulse doppler system featuring high/low/medium pulse repetition frequencies, frequency agility and ground mapping using doppler-beam sharpening. The complete fire control system will be integrated into the second production variant (PV-2) of the LCA. The compact, mechanically scanned slotted waveguide arrays in X and Ku bands, have been developed by the Electronics and radar development establishment (LRDE) labs of DRDO and have already been exported to Poland. The signal processor, also designed by LRDE, is built around VLSIs, ASICs and i960 processors catering for the functional needs of the different modes of operation.

Research Centre Imarat (RCI)'s Ring laser Gyro with a square laser cavity of cavity length 28 cms. This system is intended for use aboard the LCA and missiles with longer flight time.

@Horus @Oscar Sir I request you to start a thread which puts contribution of Pakistan in JF-17 thunder program + what Pakistan has gained from this Joint venture..I will be thankful to you.
