DRDO: Technology for a Critical Component for the Jaguar Fighter Developed

[Techy]

HYDERABAD: Technology for a critical component for the Jaguar aircraft has been developed by Indian defence scientists. The Defence Metallurgical Research Laboratory (DMRL) in Hyderabad, in association with Mishra Dhatu Nigam Limited (Midhani), Hindustan Aeronautical Ltd (HAL) and Airworthiness Agencies, has developed the technology.

According to the Defence Research and Development Authority (DRDO), high pressure (HP) compressor disc forgings, made of titanium alloy, are critical rotating parts of the Adour aero engines of the Jaguar aircraft. They need to be replaced after a specific period of operation or if unacceptable damages take place during or before expiry of their life.

"The annual requirements of HP compressor disc forgings are high, therefore warranted indigenization," DRDO said. Defence scientists have now has developed technology for manufacturing disc forgings of all the five stages.

The technology has been transferred to Midhani for bulk production. Midhani will use the isothermal forging facility at DMRL (on cost basis) for production.

DMRL has long pursued an intensive R&D on rare earth permanent magnet (REPM) which culminated into establishing process technologies for making three different classes of rare earth magnets, viz., SmCo5, Sm2Co17 and Nd-Fe-B. These magnets almost entirely cover the total spectrum of application engineering in strategic sectors, DRDO said.

In an effort to 'Make in India' and thereby totally indigenise the production from mineral to magnet, Indian Rare Earths Limited (IREL) plans to reduce the rare earth salts it sources from beach sand mineral by acquiring the technology established by BARC and use this indigenous raw material to produce technology for near isothermal forging transferred magnets in large scales by adopting the technologies developed by DMRL.

The efforts will create an indigenous source to meet the requirements of rare earth magnets for the strategic sectors in the first place and then gradually widen the scope to civilian sectors, according to DRDO.

DRDO: Technology for a Critical Component for the Jaguar Fighter Developed | Indian Defence News

Brilliant news .A lot of such breakthroughs are needed though

 

[Bossman]

Why is DRDO putting resources for developing parts for the under powered Jaguar engine which IAF is planning to replace?

 

[Raje amar]

Very Good Job by DRDO.... Keep it up.

But we need hand over the developed process and tech. to privet industrys. This will ensure most economic production and subsequent improvements in the process as well as tech.

DRDO can charge them with Licence fees or simply oction and give it to the highst bidder.

This will help to strenthe domestic supply chain for critical components.

Why is DRDO putting resources for developing parts for the under powered Jaguar engine which IAF is planning to replace?

Because these parts are VERY expensive and consume precious FoRex. This way not only do we save our FoRex but also providing employment in India.

Forging of hollow Titanium blades for Jet engine Compressor is a serious engineering challenge and if we can do it well, it is a respectable achievement.

Same is true for production of high end Neodymium Magnet and Samarium Magnet. These are the most powerful magnet known to man and they are made from rear earth metals. BARC has developed tech to extract these rare earth metals from sand and now we have refined the production process to produce higher quality super magnetic alloys.

It is another welcome step towards self reliance and industrialization.

Are these technology engine specific, or can we use this tech with some modifications on other engines as well?

Titanium blades are not suitable for aero engines because it will react with oxygen and carbon at high temperature, well below its melting point, making it very hard and brittle.

Which is why turbine blades are now made from Nickel alloys. I guess US now has started using composite blades too.

It is never enough for the defence personnel of India who are critical of DRDO products. The defence personnel of India risk their life and limb on the border so hat trolls like you can itch their behind and post s***t on the internet.

Lolx, co-realtion between their love for phoren mall and kick backs is no longer hidden .

Anyway only God knows why it's only Navy always which get satisfied with indigenous techs.

Anybody who doesnt suffer from delusion has "low self-esteem" according to you? Just shows your poor mentality.

Lolx, co-realtion between their love for phoren mall and kick backs is no longer hidden .

Those soldiers are guarding India. The day you wear the uniform and put your life on the line is the day you have any right to criticise the armed forces. Trolls like you can only comment on internet.

Tavor is foreign and INSAS is Indian.

Ask any westerner what he thinks about both rifles and you will know where DRDO stands.

 

[SwAggeR]

@Indian Patriot May be because navy lack budget. And see where we are today in naval indigenous products viz a viz Army or Air force. If you don't give chances then you won't have your own ever. Western or Chinese products weren't perfect from day one. They evolved over time.

And NSA
