@@rajarshiguchhait5643 Absolutely agreed... and out of all the central govt agencies DRDO is most lobbied and most corrupt org in India..

People study their subjects just to get marks. This is a problem with our college professional courses. Studying just to get job and earn a living is the problem. They do not get any real knowledge and understanding of their subject. Teaching system needs to change.

@@nitiKT Don't agree. DRDO has a lot of unnecessary staff is what I heard, just as GTRE, but they have good people too. Muslims and enemies are trying to run down our important institutions.Muslims are the enemy.

​@@crusoerob8550Don't forget , that We have MBA CHAUWALA and BTECH chaiwala too 😂

@@exploreandunravel5773 what about the unemployed M.Phil graduate from Cambridge 😁

thats how china has progressed. A lot of chinese senior scientists from abroad come back to china and literally set up the whole tech and taken a lead over the west. but with indians. its like they have managed to escape and they never return.

they don't get enough funds to carry out critical tech research. Without funding, brilliant people are as good as vegetable vendors. Tshingua univ of China gets more funding than our entire education budget. that's why it is in the top 10 univ these days and China is far ahead of India. We chose social justice/ reservations/freebies, so why are we surprised and should be content with what we have achieved. it is up to people who avail subsidy if they want to give up voluntarily for the greater good.

No chance....they're happy to create emergencies and then make emergency procurement.

@@hera-nf8mz yes, till some years back, indians had no national pride left. The CORRUPTION in the country and a non functional self-serving political climate had made it impossible for ambitious people to hope for anything in India. There is no guarantee that those bad days will not return. So can't blame them also.

I don't have any idea in the field, Just asking cause I don't know, If metallurgy technology is that bad how were able to excel in rocket technology, naval ship building ect.. ??

there are already multiple prototypes ready and they go through multiple tests but we lack in technology not in funds

@@sashankg1 exactly 😂

The issue is not funds, but the lack of knowhow about the alloys and their manufacturing and the ability of industries to manufacture these components with the required precision and quality. Its not easy. China which has a much larger and diverse industrial base than India tasted success in developing a domestic jet engine only recently. And they might have relied on industrial espionage of Western firms to get some of the knowhow.

Like 40% of Armys budget goes for Pensions so our Military budget is somewhere around 50Bn $ out of 84Bn $

No not completely Nehru built IITs and NIT, this is coming from a second gen Bhajpa Supporter. Stop blindly following IT cell bullshit

Congress brought Nuclear Submarines and bhramos to India.

US is never worried about india buying 200 percent from Russia defence companies. All this is lip service . US congress will never give the green signal to transfer aero engine technology to any country. Only seven countries make aero-engines on their own and Ukraine is one among the seven. Even the sea gaurdian drones leased to india is now also operated by general atomics. Pakistan F-16 r now also monitored by US personel directly who r based in Pak air bases 24/7/365. That was the agreement between pakis and Americans. US fears that pakistan would allow third parties to check out F 16 tech. If that's the case with Pak who is a non- NATO ally, what will it be with india who is only a strategic partner to the US.

funny that one time people came to india because that is were everything was technology science and so on, and now you have to go abroad to get this stuff, most of which is derived from your stolen knowledge. india had meturlurgy thousand years ago guess that is what happens when you dont protect and keep what is yours.

full of BS, even with TOT for Su 30 MKI make in India for 20 yrs, India now still needs directly import over 1500 parts and raw materials from Russia and the cost make in India Su 30 MKI is more expensive than directly buy from Russia

​@@firetree2007There has been no ToT for Su-30MKI. Apart from avionics, HAL merely assembles the jets from CKD kits imported from Russia. Localisation of its components in miniscule.

Full ToT of GE-414? Are you sure, actually, USA does not have such a track record of full ToT of its advanced equipment, even to its close allies such as Japan.

Are you nuts? Do you think this is like making dosa? Just search how much money china has spent chasing this tech and how much we have. GTRE designs and research engine tech. HAL only assembles it. Know the difference? No private players will be able to put in money and get a 5th gen engine. How many companies in the world have it - 3 or 4? How many years have they worked on it? At least 30. How much money they have put it? Atleast 10 billion USD. Do you think any private company in india is going to spend that time and money which will probably generate profit after couple of decades? Talk sense.

@@desibigfoot3874 by the way are those Lockeed martin, GE, Boing etc are owned by governments?! All are private companies. Here we have all those govt owned white Elephants who do just assembling of kits 😂 only big targets big budgets no production 🤣. I talk sense because government is blowing up my tax money since 35 years in the name of engine research😂. Tejas designers got fedup waiting for kaveri engine and went with GE engine after redesigned the air frame. GTRE should be shut down and hand over the engine research to private companies. Otherwise these government paid scientific community will take another ten decades and have junk on the table saying this is what they could do.

@@desibigfoot3874 you are the crazy nut, we are buying from a private company now dummy

@@changappalarny4701 India does not have a capable private aerospace ecosystem. The Western nations had it from the very beginning. Our private firms can _manufacture,_ but do not have the ability to _design_ a jet engine or a rocket engine or a fighter jet from the ground up. And these metallurgy stuff is quite tricky in jet engines, and is a closely guarded secret by Western companies. You need to know what is the right alloy to be employed for certain components, or they will fail in operational use. We may ask Russia for help in this, but then their jet engines are notorious due to their poor reliability (again down to manufacturing quality and metallurgy). Without hand holding by govt organizations, private aerospace industry cannot take off here. For that matter, I have seen rumours that ISRO's new semi-cryogenic (aka kerolox) engine has been facing delays due to manufacturing issues. ISRO doesn't manufacture these liquid propellant engines and other rocket components. They give the designs (in this case, bought from Ukraine) to private firms like Godrej & Boyce or L&T to manufacture them, and these companies have been struggling to produce some key components with the required precision. So, the issue is fundamental and isn't easy to solve by simply shutting down GTRE, HAL or other state-owned firms and giving the job to the Tatas, Ambanis or Mahindras to design and build jet engines.

See Japan they first developed 60 kn engine then increase their level to 120-130 on and now 180 kn engine . that's approach india should follow .

What do u want them to do?

Tejas Mk2 is larger and therefore uses the more powerful F414 engine rather than Mk1's F404. What exactly is the problem you see in it?

😊it is not that simple, the complexity lies in manufacturing. Master copier china will not be able to reverse engineer a jet grade

@@nighthawk4028 Its ok India did it nearly two years ago they have everything they need now to make a jet engine

How do you know it is "basic" metallurgy issues? You have any idea of the sustained high temperatures and pressures that a jet engine's turbine blades and other components have to endure for reliable operation? The designers would need to know what kind of alloys to use for these components and how to manufacture them. Most of these knowhow are closely guarded secrets by Western firms who spent billions into their research for decades.

no the tech is the issue.

Our govt departments are inherently bureaucratic and inefficient to be sure. But then, developing a jet engine that generates the necessary thrust levels while remaining small and light enough to fit in a small fighter jet isn't exactly an easy task either. And then there is the exotic alloys that its components require for reliable operation. Many of these knowhow are closely guarded secrets by Western firms.

@@vineethgopalakrishnan3967ever heard of espionage? Why can’t India buy the manufacturing secrets from Russia?

China knows well that by the time Indian bureaucracy gets its act together, they would have already built a better engine that what US has offered India.

Stolen technology will always have gaps. GE414 is there fore more reliable than China 180 KN engine. China plane will fall from the sky by itself on the way to India. Please come to clean up the mess.

Its not just about the power, but the compactness, quality and long-term reliability of the engines. A small fighter jet like Tejas needs only a lower powered engine, but it needs to be compact enough and reliable. Ask IAF about the notorious reputation of Russian jet engines. Half of IAF's Sukhoi and MiG-29 fleets are grounded at any given time due to their engine troubles and other mechanical issues. Its too early to say if China's domestic jet engines fares any better in reliability and engine life.

@@vineethgopalakrishnan3967 we should go for Al-41 new engines for Sukhoi jets that has resolved this issue and quit using old Al-31 engines.

its not how beautiful but how powerful is the aircraft ;that matters in the warfare keep your aesthetics with you ricebag

Who cares about the aesthetics of a fighter jet? They aren't going for a fashion parade you know. 😂 What matters to a buyer are its capabilities, not how it looks. And what do you exactly mean when you say Tejas is hideous? That it lacks canards? Tejas looks just what a small double delta-winged jet would look like.

Typhoon does not look any different than Tejas aesthetically. Maybe Gripen and Rafale do. But the prices on those planes........... i like the look of the Tejas. Its compact and looks great in flight and on the ground too. Its interior is basic, but fancy interior does not mean better.

@@mth469 ..Typhoon, Rafale, Gripen all look really good...We decided to Copy Mirage 2000, even though we couldn't still match it's aesthetics.

@@abymathew295 I disagree. Tejas MK1A looks better than a Typhoon in flight and more so on the ground. The Typoon appears unbalanced on the ground with the nose pointing up into the air. Rafale is a 90 million dollar aircraft so for the price, it better be looking better than the Tejas MK1A or MK2 for that matter. The Grippen has good aesthetics both inside and out, but the MK2 will close that gap. Overall, the Tejas looks great. It looks like a cross between a Mirage and an F-16 in a matte grey color. More importantly, it can be manufactured in large numbers cost effectively, can fire all kinds of weapons (Indian, Russian, Western), has AESA radar, full FBW and a proven lightweight, fuel efficient engine. It also has never crashed and has a perfect flight record. It is being integrated into a networked AEW & C that is being built. These days is as important as the aircraft itself. This is the best thing to have come out of India in a long time.

If learning to design and build jet engines was something that could be accomplished by "fiddling" with existing engines in fighter jets, there would have been so many jet engine manufacturers in the world outside of West and Russia. You need to know WHAT alloys are used in each of the engine components, HOW they were manufactured, and WHY they went for such an engine design. Its not easy.

@@vineethgopalakrishnan3967 but drdo and Ada or private players in India are way absymical or below par the competition....really is there a focus effort or just sarkari aur kuch kartein hain attitude

we're using ge 404 engines, ge 414 has more power.

As you have yourself pointed out, Tejas is a LIGHT combat aircraft. As originally envisaged, it didn't really need a more powerful engine than the F404. However, IAF's expectations from the aircraft with regards to its capabilities like weapons load and operational range has changed and Tejas Mk1 powered by GE F404 do not meet their needs. They need a larger fighter jet - Tejas Mk2 - which consequently would need to be powered by a more powerful engine, which is the GE F414.

China J-20 is now powered by 180 KN heaviest engine WS-15. China has become fully independent from Russia in engine

💯 correct

It is not about designing but it is about having fixed capital investments for advanced manufacturing. India cannot conjure $15 billion for MMRCA for nearly 20 years. American companies are going to invest that money and start the manufacturing.

basic equation starts with money and socialist mentality
