CSIR laboratory to manufacture critical composite air-frame components for LCA Tejas

Usage of indigenously developed technology lightens air-frame by 20%

CSIR-National Aerospace Laboratories (CSIR-NAL) has received an order of more than Rs 100cr for delivering critical composite air-frame components to Hindustan Aeronautics Limited (HAL), for the LCA-Tejas Full Operational Capability (FOC) standard aircraft.

Dr. Harsh Vardhan, Minister, S&T and Vice President, CSIR congratulated the team of CSIR-NAL and said that this is a unique effort and highlights CSIR’s commitment towards the Make in India initiative. “The cutting edge technology is one of the critical technologies that make the LCA a 4th generation fighter aircraft” added Dr. Vardhan.

DG-CSIR, Dr Girish Sahni while congratulating the team at CSIR-NAL stated that the use of this co-curing technology in LCA has resulted in 40% reduction in the part count, 50% reduction in the number of fasteners, and 30% reduction in the assembly time when compared to a conventional metallic air-frame. The usage of composites has led to an overall weight reduction of about 20% in the air-frame.

“It is a matter of pride for the country that LCA’s percentage deployment of composites is one of the highest among contemporary aircraft of its class anywhere in the world and this order of Rs 100 crore plus value is a major achievement for CSIR” said Dr. Sahni.

CSIR-NAL’s collaboration with LCA program started from technology demonstrator (2 aircrafts) to prototype development (5 aircrafts) to limited series production (8 aircrafts) and Initial Operational Capability (IOC) standard production aircrafts (SP1 to SP20). The initial IOC order of 20 sets is nearing completion. The challenges were to develop the co-cured complex components indigenously during the time of technology denials and sanctions from other countries. Moreover, the autoclaves necessary for processing composite materials were also developed indigenously by CSIR-NAL. This homegrown technology developed by CSIR-NAL was used in realizing primary air-frame components of LCA like Fin, Rudder, Wing Spars and Fairings, Centre Fuselage and Main Landing Gear components.

CSIR-NAL has now further received an order to supply additional 20 sets of parts for FOC standard aircraft (SP21-SP40) at a cost of Rs 100cr plus including development of tooling. CSIR-NAL has identified a private industry, M/s Tata Advanced Materials Limited (TAML), Bengaluru, as a production partner.
 
Why bother? Might as well order Gripen to replace MiG-21. Both use America engine anyway. It's not like Tejas is an Indian plane. No. It uses America engine. Prone to sanction.
You forget that Kaveri is now on track.

s long as its control of indians we are not worry :lol: i will loose my sleep if project gone in hands of Americans Russian Israelis hands :partay:
You are right.

It will be in better hands if those hands are... french ! :smitten:

This would have been a nightmare scenario for the USA - if China's manufacturing base, India's software base, china + India market were with the Russian MIC. thankfully, China picked Pakistan's side leaving an india sized footprint for Pompeo to land on.

More importantly, would the LCA then have ended up looking like the JF-17 or J-10?
Would China’s greater indigenous manufacturing resolve have actually made it a successful project rather than the horrendously delayed and confused sponsor project it is?

And finally, would many IAF pilots be still alive instead of risking their lives on increasingly archaic (regaedless of electronic upgrades) platforms?

The LCA design was already frozen years before.

It wasn't a joint development. The Chinese didn't have the technology we needed at the time. We were looking for a digital FBW.

And finally, would many IAF pilots be still alive instead of risking their lives on increasingly archaic (regaedless of electronic upgrades) platforms?

The Chinese wouldn't have helped there. We should have taken Dassault's analog FBW offer in 1988. Would have saved many years of flight testing. Instead we lost 6 years.

An early LCA success would have only cancelled the Bison program, and still put the IAF at risk anyway, this time without upgraded Bisons. What really failed the IAF was the failure to have a M-2000 production program in parallel with the MKI, not the LCA.

That 2001 RFI should have translated into a contract by 2005. But then, the IAF got greedy after the Americans offered the AESA with their SH and complicated the procurement process, which became MMRCA. The IAF should have stuck with the M-2000 at the time. They could have been 200 jets stronger, and also transitioned to the Rafale by now.

If ....but... had we this .... could of that.

Yes we have issues but all of them are within Indian capability to over come.

All we need is money and decisive decision making.

Order second batch of rafale
Open private sector involvements in mass manufacture for tejas.
Get outside help on engines technology
Develop amca with world class company in partnership be it dassult Ir Lockheed or sukhoi.

It's all doable

By 2025 india should have over 70 rafales and over 80 Lca. By 2030 double those nod

It's all doable

Look how huge the Indian gdp is today compared to 2005
