AMCA - Advanced Medium Combat Aircraft (HAL)

[Ar.gaurav28]

Anything that comes out of a defence PSU's mouth has to be taken with a fistful of salt. Let's face it; we brag first and then do not deliver.

I would assume this to be non-existent until I see these jets at least taxiing somewhere. Let's not get ahead of ourselves knowing how HAL, DRDO labs and ADA work.

Even after Dalai Lama left his motherland still they are running their government in exile! A faith that one day Tibet will be free from CCP there will be freedom soon!
This shows we need to have faith & a positive outlook...

Things are changing...there is a shift new world order, new alliances are emerging, with changing geopolitics to survive people will adapt! There is a push for corporatisation!

New Defence eco system emerging many private companies are producing stuff that was once imported!
HAL even now understands it’s place, it will be the assembly hub for the various platforms!
Understand this, a country that has ignored it’s defence industry for 7 decades can’t become a power hub in few years it will take atleast a decade & alot of help from it’s allies(TOT)!

What is?
The process is developed by DRDO and the company making the forging press is German. I don't see a French involvement here.

The high pressure compressor discs forged by this would be world class and would reduce Co2,NoX and other gaseous emissions it's because it provides higher efficiency in compression .

Compression system has to deliver increased OPR as required by the thermal cycle and has to do this more efficiently so as it does avoid excessive increased cycle temperatures and weight to avoid reducing the benefit from the new cycle.

Yeah right India should have bought that lavi project from Israel we would using a great fighter by now & china would still relying on cheap copies of russian jets!

At the same time, India got a far experienced and tech-advanced partner - Dassault to provide "consultancy" from the beginning, instead of a half baked plane for Chinese. And all these super Israel aviation techs were also available for India. I am not what does India need to build a great fighter.

Dassault to provide "consultancy" from the beginning

Not from the beginning.. but only in the beginning. DA abandoned the Tejas program midway. It came to fruition only and only because of untiring efforts of our scientists, engineers and leadership both in public and private sector.

In a way it makes me glad we didn't buy the Lavi blueprints.

That same far experienced & tech-advanced partners were banned to help us after nuclear tests!
Even a half baked plane & reliable partner is better than starting from scratch & not to mention it is the Jewish community in America which has a huge contribution in its defence technology!
& most importantly...
Israel wouldn’t have abandoned us, they went against American wishes supported us in every war we had!
also,
please check lavi specs and compare them to mk2

Was that good or bad thing we’ll never know...
But with the similarities between lavi and tejas mk2 it’s hard to believe there wasn’t any assistance from them in this project!

There have been assistance from many quarters:
1> France: Overall design, construction, avionics design and philosophy.
2> US: FBW (to some extent), engines.
3> Israel: Avionics
4> UK: Radome, IFR probe, EJ seat
5> Russia: Weapons, Navalization

I’m thinking in terms for just mk2 thus will omit France & Russia out of it...as no doubt tejas was baised on mirage same could be said about TEDBF(rafale) although better design, still much resemblance in design language! AMCA‘s inspiration from
F22 & f35(lately)
But nothing actually matches mk2 design double delta design from mk1 close coupled canards like lavi...exact same length, weight might also be similar & engine thrust also in the vicinity!

Yeah Mk2 design is very unique!

Does the AMCA project use engines produced in India?

The sanction for nuclear test was beginning in May 1998.
The demonstrator of Tejas: TD-1 rolled out in 1995 and TD-2 in 1997

And it was TD-1 that took the first flight in 2001. In other words, the design work was done before the nuclear test.

In later stage mk2 configuration .


Till then ge 414 , contract manufacturing is nothing sort of achievement even if qe are doing it

Nope as the variation is in the ratio of bleed air going through the engine, that might help in keeping the engine cool thus reducing the infrared signature!
High efficiency mode:-
View attachment 91699
High thrust mode:-View attachment 91702

This is something parallel to VTEC engine of cars which changes its valve adjustment to suit to its power. Rather than setting engine for highest efficiency around 80 KMPH, it will adjust to the RPM of engine and give higher efficiency at that speed. Similarly, adaptive cycle engine adjust its ratio to provide highest efficiency at particular RPM by adjustment of bypass ratio. It is an optimization to extract maximum from same engine by varying different parameters which remains constant otherwise in normal engine. In current missile which uses RAMJET solid fuel engine, similar technique is used. Earlier, it was not possible to very the burn rate of solid fuel but now it is done by bypassing the air. SFDR uses this technique to control the speed and improve the fuel efficiency.

Saraswat noted that the project to develop a Light Combat Aircraft was initiated in early 1980s but soon after Missile Transfer Control Regime (MTCR) came into effect in 1988.

"All suppliers cancelled their agreements and European firms also stopped cooperation. When such a situation occurred, we had to do everything ourselves. This was a major setback," said Saraswat, who also held the post of scientific advisor to the defence minister.

This situation continued from 1980 till 2000 when the first aircraft was rolled out, he said.

"Time was taken to overcome the blocks created by MTCR. This is the reason for the longer time taken," he said.

In 1986, they were flying their prototypes when these so called friend stopped helping. The years from 1980-88 were wasted like this and overall 20years were wasted due to unreliable partners. From 1980 it took 21 years for first flight for tejas in 2001 & only since 2014 we have actually sincerely worked on tejas...
this is the reason even when USA is coming to us all arms wide open we are still sceptical...

We shouldn’t give them that much importance, no point of waking them out their dreams!!
China has started to do it from behind & USA is already doing from front soon taliban gonna stuff up their mouth!
So wteva they say...just smile & enjoy watching them getting f....d!

Wy to answer. Just increase its sales , khud hi chidd jayenge

From your own source, why do you think it took 5 years from roll-out to first fight of TD-1?

USA contribution, this was LM:

Post Pokhran US FBW collab also came to an end:

Early jet engines were inefficient because hot end engine components could not be operated at high temperatures. There are a few major difficulties in reaching high temperatures: Metals and alloys become soft, corrosive and melt below 1500 o C. Their creep resistance also reduces. Nonmetallic materials though oxidation resistant and strong at high temperatures become brittle. Engineers, therefore, have resorted to a few novel design techniques such as using single crystals and composite fibres. The above paragraph, while describing the new technologies which are coming into use in a significant way, also underline the gross failure of Indian industries to acquire or develop them for industrial exploitation. We realized that Hindustan Aeronautics Ltd did not have the necessary expertise in these areas which had to be either developed in country or acquired from abroad. It is in this context that India signed collaborative agreements with France and the United States. The collaboration with France was for participating in the Project Definition Phase (PDP) of LCA (Tejas). The US collaboration was extensive and useful in buying jet engines for the Indian aircraft and co-development of the fly by wire system. India did not have the necessary know how to make the fly-by-wire system. India planned to acquire this knowledge from the US. Indian engineers got the necessary training to design the fly-by-wire system by working in US laboratories. The collaboration was successful though subject to the vicissitudes of US policy. They refused to help in developing the control laws for a fly-by-wire aircraft. India developed this critical software on its own. India was willing to extend the collaboration with the French beyond project definition to full scale development but they insisted on India choosing and absorbing only those technologies which they recommended, especially the hybrid fly-by-wire system. Even after considerable persuasion the French did not relent and the collaboration did not go beyond the project definition phase. Surprisingly, the collaboration with the United States, for the General Electric F 404 jet engine went smoothly.
