If 10 years were not wasted, then first batches would be flying on Tejas right now.

May India have it's own indigenous engine till the end of this decade 🤞🤞.

If true, this is heart warming news😊

Good news , we are moving in the positive direction ❤

It is imperative that flying testbeds for the engines are locally available as well to cut down on development span.

So what I am able to understand is that the technology for Kaveri was already developed, and now it is a matter of building it with better parts. So is it possible that while this is being done, GTRE can improve the Kaveri engine to an equivalent of GE F414? If all goes well, we could have indigenous engines powering LCA Mk2 and TEDBF

भारत ही बनाएगा लेकिन टेस्टिंग भारत में ही हो टेस्टिंग बनते ही भारत इंजनो की झड़ी लगा देगा।

Its a step in right direction...but in future Tejas Mk1/1As will need higher thrust engines because 5-8 years down the line many newer electronics or upgrades might be added to those aircrafts, which in turn will need higher power than currently used engines, otherwise there might not be enough upgrade potential...after this 80kn design is successfull GTRE must try to upgrade this or try a new core for 90-100kn (with afterburner) engine...apart from Tejas re-engine requirement, this 80kn design might also be used in Marut Mk2 design which was shown earlier by HAL/DRDO

Very nice to hear that. We should use LCA Tejas model and the Kaveri Engine as flight bed. Jai Hind Jai Bharat 🇮🇳

Russia ko dikha do sab kuch. Russia khud nahi chahega ki India yeh engine successfully bana paye.

Same wahi hisab he lithography wali machine ka Jo chip bunati wo duniya me 2,3 hi jugah bunti bus

80KN is good enough for a dual engine 4-4.5 Gen fighter.

Abhi development bohot tez hone wala hai.....private contractors jo aa gaya hai. Some of Godrej's test unit , after successful dry thrust trials would be equipped with a lighter afterburning section , already in development by GTRE and that would be tested in Bharat itself on Sukhoi test bed . Due to being developed for Ghatak UCAV, the Godrej units are already lighter than the actual Kaveri - fitting it with a state of art afterburner has the possibility of making it even better than the GE F404. Private contractors are very fast in developing trial units, they employ IIT pass outs and highest rank holders in engineering as supervisor - there is no import lobby to hinder them using vampanty unions.

Godspeed. Fingers crossed.

It seems that endurance is something that is never discussed here. Last report of Kaveri also notified problems when it went over Mach 1. I am not an expert on gas turbine design, but, I think the way to develop a predictable and reliable engine would require an agile methodology instead of Waterfall and agile would require frequent testing with predictable outcomes and small steps.

luv you bro .. keep sharing the info jai hind

Jai Shree Radhe Krishna 🙏🙏🧡 Jai Bharat Rashtra 🙏🙏🧡

Now Indian Defense Forces and Ministry must understand that no country is gonna give us state of the art technologies for our defense needs. We ourselves have to develop them. So, R&D must not stop due to budget issues. Govt. Must ensure an uninterrupted budget for our hi-tech defense needs. Else, we are never gonna be independent for our defense needs. Also, these technologies have various civil uses and pay back the development cost in multiples.

The best approach to a test engine is to put it in flying aircraft. This will give us realtime data

Explained very well

Kaveri engine 80kn is ok to be used in duel engine aircraft like tedbf ,su 30 mki,even in rafale.if this project was given to any private company we got engine 10 yrs ago itself

stretch it to 85KN and use it for Tejas Mk1A, even if it means using Snecma core.

Well presented, bro

Very good work going on

high time we accept merging ADE & ADA is of critical importance and need of the hour

Kon subse behtar tureeke se engine ko control kurke use kum fuel consumption me jada or efficient power nikal ke dede wahi Raja he

Let's hope for the best

सैकड़ो रिटयर मिग 21,23,27 कही ना कही रखे गए होंगे.. क्या उनको कामाकाजी सिंगल यूज ड्रोन या मिसाइल जैसा नही बनाया जा सकता..

cant we use 2 GTRE 80KN version on TDBEF?

It's so much valuable and key part , that's engine for jets , civil aviation , helicopter , uav , ucav and marine services , and our our government , either all time since independence ignored , no financial , no moral support , no system encourage. It's a crucial time to restore and back- up to be given . Minimum 2 billions dollers allocated for. This programme with free- hand for development and research program.❤❤❤

Very true 😮

Dikkat ekhihe kubhi kuch jada kurdete kuch Kum kurdete exact ratio nahi puta metallurgy ka or uparse blade ke Jed ke liye bahut bareek technology use hoti

Tejas ho ya AMCA Kaveri ko roll out karney nai bahut deri ho rahi hai, waisey ho bhi jata hai tow sirf Tejas ke liye and AMCA ke liye aapko 110 KN se kam ka kaam badiya nahi karega, ye achha hai yadi India 80 KN Kaveri ko test mai pass kara leta hai tow ye bhi achha sanket hai.

Best Technical Video

Main he blades ,or frame ki metallurgy or fuel consumption in proper balance

Govt. na to iss project to Marne deti hai na jeene deti hai 😢😢

India should have its own test bed so that we need not require to send our engines to other countries for testing as it will save our precious time during our engine development.

It's surely gonna incorporate technology like Crystal Turbine Blades and engine temperature resistant material gained from F414 INS6

The best part of this programme is it's time line.

It's a big development

It's good news that we will have a home grown engine but I think it shld churn out 85kn atleast to b a viable solution for LCA 1A

Cost cost cost ...bhai har samay yahi rona koi acchi baat nahi....khuch paane ke liye kuch khona padta hai...Bharat sarkar ya to paise bacha le ya fir Bharat me Jet engine development par kaam karne de...waise bhi Kaveri ke last 10 years to fund rok jar kharab kar hi diye hai.... Kul milakar Bharat sarkar Aloo ke paise me paneer ki sabji banana chahti hai.🙏🏽

I am surprised of this "new" engine (or not!). First of all what the f*ck is a "new" engine (as if there is an "old" engine; & if so when did we build that?). It shows glaringly, the lack of comprehension of "developing" an (any) engine. It even reflects the chap's thinking who wrote this - even his idea of an "engine". First of all (before all others jump on my head), we have "not" (repeat "not") developed an engine, built one based on a design & flown it successfully. Till such time it can't be called an "engine" even. As a student in 1960s, a "computer" was big topic for discussion. Very few have "seen" one . What is a "computer" (in popular imagination & terminology)? Me, along with two of my fellow students had a bet that there is one in "electrical" lab. They went to it & asked the Asst. Professor there, "Sir is it a computer ?" He replied "Yes. it was". His sarcasm was palpable, as he didn't mean a non-functional one (for repair for a long time), computer! An IBM 1620 is a computer then, (prized possession to show off), but compared to a Laptop now it is a bullock-cart. Returning to engine for an aircraft (any aircraft), it is to be first "designed" which is a laborious process, needing pencil & paper (or computer with a good screen) and with the brains of at a dozen engineers, breaking their heads. After the design is complete, they go to the Lab & with the necessary raw stock, to assemble an engine. Before the final assembly of a new design, there could've been a thousand changes! But it may not be that, it can be mounted on an aircraft as power-plant & make the aircraft fly. That stage will come after trials & errors lasting a decade (even in USA, UK or France) or more. We Indians, lacking even the ABC in designing engines, were at it (the task) for half-a century, while the poor nation waits for it to be fitted & flown! This engine on the boards for so long was"CALLED" (everything needs to have a name, no!) by various names - lastly the "GTX", later with further modifications (a hundred must have gone before) was re-christened "Kaveri" after a river near Bengaluru (where the lab, GTRE was located). Let's not call it by any other name & stick to that, till it is fitted on an aircraft (Tejas, now) & flown with success. In aircraft business (building it or its parts). modification is carried out when there is need. Several such "Mods" would be there, as indicated by a (metal) Mod-plate put on the thing, where the Mods undergone are crossed out (X). So have patience!

४२ घंटे मे १इंजिन बने ऐसी तय्यारी करे nanki ४२महिने ५००००इंजिन ka तय्यारी करे manufacturing chains ka jarurat hai MP- UP GUJRAT-MAHARASHTRA मे जमीन पहले से तय्यार है

It is not easy to catch up in engine technology. We will keep trying.

My question is why can't we develop a twin engined version of the Tejas fighter. We will get 80+80=160 kN thrust. But thrust to wt ratio will go down. Which can be offset by a lighter payload?

👌👌👌

Nice🎉

NICE 👍

Sir i am MSC physics student, how can i join drdo (specially In Gtre)

Great Technical Info.. Sir.. what is your opinion about making 5% of turn over amount of Defence manufacturer Be made TAX FREE and Mandatory to be spent on R & D.. in return giving them share of IPR... It will give a lot of encouragement like in this case for Godrej..

Sir, what is the actual minimum kn of thrust required by LCA Tejas??

Video on why we don’t have test bed in India (My little understanding is we need an old plane to mount the engine right)

Ted bf ke liye shi h kavari.. 2 ingine ke sath 146 kn thurst milega joki shi rhega

Bhayya DRDO reform video kab upload karega

This can be used in airforce variant of tedbf

Subodh bhai iran & pak ke conflict ko leke video banaiye..

We need to accelerate the production ❤

Jispe lithography wali machine aati kum nanometer me wahi chip ka badshah he agar baki sub resources tumhe tub

Etni heat burdass kurneki takat blade me honi chahiye or frame me

& in future when the time comes for the engine replacement of Tejas mk1a we will replace the 85kn engine with 80kn engine ? 👏👏

good news

Agle 10 saal tak bhi ready nahi hoga..it is bit frustrating now. Turkey and South Korea already started 5th gen test flights and India, even funds are not sanctioned

Chalo, at least now ek sahi disha main chal padhe hain.

It has taken more than 7 re-birth, now lets give it Nirvana.

Bde dhile hai GOI inki testing facelity बनाए जल्द से जल्द एक ग्राउंड बेस जो शायद tamilndau में बना रहे है। एक राजस्थान और सियाचिन में बनाए हाई एल्टीट्यूड पर। साथ ही इन्हे टेस्ट bed de। Ek सुखोई 30 mki aur ek koi air india ka commercial old plane Ye kaam to kiye ja skte jald se jald

DRDO Ka Cristal blade Kaha hai Why directionally solidify blade kyu

👍

Jay Hind..

Is it the GTRE kaberi engines is Turbo jets engines ? For which the fighter jet this GTRE kaberi 80 kn engines has manufactured ? Will it be capable & sufficient for Tejas Mk-1 or 2. ? Matter is that Turkey has manufactured kaan as 133 X2 = 266 Kn and Chaina have manufactured as 153X2 =306 Kn engines power fighter jets . So to over come for manufacturing fighter jets ,india needs 175 to 180 KN . Indias competitors is Pakistan China & turkey . india have come over them

Metallurgy dept needs to work on it.. needs more fund

If you are able to test the Engine on a testbed then you definitely have it. It was stupid to stop the fund.

Fuel consumption me hi sub aajata baki sub purje

Why we still don't have Testing facilities

तेजस मार्क 1 ए में जीई एफ 404 इंजन का प्रयोग होता है वो कितना थ्रस्ट जनरेट करता है.?

Add 10 more years to your estimate.

Unless gov is serious and orders a flying testbed we are getting nowhere in fighter jet engine

If the engine is weak cant we use two together in a single jet?🤔

Jo ese sahi control kurliya ,or less fuel consumption with more efficient power bungaya engine samjlo

Pity and real shame that despite much sloganeering of “atamnirbhar” India defence department is spending so little on critical defence technologies and had all but abandoned jet engine.

why we teat our engine in russia not in india. Test bed India mein nahi hai kya?

I thik next batch 94 aircraft Should be integrated by this egine so we have 6-7 yrs

भारत कब तक अपने जेट इंजन की टेस्टिंग रूस में करते रहेगा आखिर कब भारत में खुद की जेट इंजन टेस्ट फैसिलिटी होगी

Jai hind🇮🇳

Jo tranfer of technology GE nhi dera usme R&D krni chaiye...20%

So the company that makes my fridge also makes jet engine?

80kn isn't less considering future upgrades?

Sub control kurna he tureeka sub jante engine kese chulta bunta

I wonder why Kaveri engines can’t be used in a twin jet engine fighter, that would give the necessary thrust… does any one know.

We should develop our test bed also.

10 साल पहले फंडिंग बंद कर देने के बाद वापस फंडिंग शुरू कब हुआ.?

Aaj ki BHARAT hai karke dikhaye ga

Fuel ka jo injection tum engine me deteho uski ratio sahi ho

India must have testing facility in India

It takes 42 months to manufacture blades. Then how does others do it.

It means 2030 tak ayega engine

Sir is india getting closer to having a own engine?

Dikkat kyahe kyu engine sub buna nahi pate

India ke liye fighter jet engine making bada mushkil kaam ho rahah hai. china hamse bahut aage nikal gaya engine making mein.

Bro, why not make 130KN turbine engines this will make Bharat have high capacity defence aircraft.
