AMCA - Advanced Medium Combat Aircraft (HAL)

Brother You should have said very clearly that your intention was to use "Synthetic diamond" and not regular expensive ones. (Bruh/lol)
-

Engine blades will be made of whatever they are mostly made up of. Read this:

"Modern turbine blades often use nickel-based superalloys that incorporate chromium, cobalt, and rhenium."

Please end this debate with regards to diamond here itself. No need of using diamond.

I reported my own post, man

bhai protective coating to rahegi na

CO2 ban ke ud jayegi sari coating

Look up burning diamond on youtube.

Bhai, I am asking abt synthetic diamond (zirconia)

 

[SwordOfDarkness]

Currently manufacturing is not advanced enough for either make blades from synthetic diamond or diamond.
How will you crush the material and after making granules how will you make blades. Current manufacturing only supports subtractive manufacturing to make high grades parts.

Nah, current methods can make them from diamonds very easily. Only problem is, it will all burn and disappear the first time you run the engine. Thats why we need special types of "diamond like" material, that is chemically different from a diamond.

Synthetic diamond is the name for diamond made in lab, chemically same as diamond in mines (made of carbon, which burns). Zirconia is different

idk abt that

Do you even know how expensive this technique of using diamonds for the engine blades be? Go and look at the price of diamond just 1 KG, it's like 1,00000+! So if we use diamonds than it will cost upwards of 5-10+ Million (You do the math and find out but the cost is not going to be economical) so no diamond.

Actually diamond is quite cheap.
Diamonds are formed from pure carbon, one of the most abundant elements on planet Earth.
The price of diamond is artificially hyped by companies.

But processing diamond to build the blade is completely different thing:
Are you going to "melt" them to a new material or just attach them to the surface of the blade?
No matter what you do, you are going to see the new problems.
Devil is in the detail.

And when you try to sell back your own jewelry with the diamonds, they undervalue them so much that you think why you agree to buy them in the first place. No diamonds by themselves are not valuable. They are only valuable to the men as in making the women feel so special that they are willing to do special favors for the men who buy such diamonds or forgive their men's trangressions whatever they may be. Diamonds are the easiest way to get to a woman's heart.

Conglomerates can and do work

Hmm, but..
1. Why did NG & MD both find new homes in aero companies again and not "conglomerates"?
2. The reason why these companies work & are world-beaters is that there is no gov coffer offering them job security- they hire the best, give them the best facilities & come out with some great products that set the pace of tech development for the rest of the world to follow for next couple of decades.

HAL has many areas to criticise them but this is just farcical thinking.

You may want to re-visit the fact that the original airplane was created by two bicycle boys- just don't see that passion happening in any gov set-up. Had the same money and resources been provided to some enterprising techpreneurs we would have reaped 100x more RoI as a nation. You see that happening slowly now with the new DAP setting aside funds and opening DRDO labs to "capable parties"- GoI is belatedly making amends.

1)Because no one else saw value in buying a drowning company, and only their competitors had much to gain from buying them out to gain experience of their designers.
2)And then they charge you for it all. Govt PSU's have enabled India to have a decent military RnD without breaking the bank. Check diff b/w AMCA and F35 dev cost. Check diff b/w SpaceX and ISRO cost.

Nah. Private companies exist to make profit, not to advance national interest. Check the amount of money US has to dump to get comparable platforms to their peers. They spend 2x of what the rest of the total world does. They are not 2x as powerful as the rest of the world. And BTW, our scientists were also using bullock carts for transport when our rockets were first built. Cant fault their passion. Some are lazy af, but can not brand everyone as bad when they tend to get stuff done despite roadblocks. Say one thing that military asked for and DRDO gave up on.

Private-Govt mix is best. Govt develops the critical parts, private companies build the non critical parts to help speed up production.

1. It is only looking cheap because you are converting ₹ spent over several decades to $ based on the interconversion rate today.
2. If you do a more realistic conversion like GDP (PPP) vs GDP nominal then does it look as cheap?
3. US can spend 100x because they print the $s will gay abandon and then re-invest all of them in their own economy- I'm not sure why we can't get on that positive spiral (not the printing, but the In-house spending)?
4. With the cheapest so called research why did we get the shameful tag of the biggest importer of military goods world wide?
5. What world beating tech have DRDO scientists cooked up in their own time and own resources? Like may be an attempt at self driving car tech? Why do they have to be dependent on service *SQRs to get their creative juices flowing? It is just a job to them & job security sprays water on any fire in their tummy they may have started out with.

Private-Govt mix is best.

Of course it is best- infact it is the only course of action since no private entity will invest billions of dollars in facilities that can only be amortized when multiple national projects use them & scales of economies get worked several times over. But my view is gov should do no more, fund & own the resources (hard assets), fund the right companies & people and let magic happen.

1-2) 300+ billion by US vs 10 billion by DRDO, world of a difference by any parameter.

3)Nope, they cant. Inflation is a beech.

4)Earlier DRDO would produce, Govt would call it a success of "Tech demonstrator", then import. Even Tejas is alleged by some to have been intended as a TD, but was forced through because of HAL+DRDO perseverance and Parikkar support.

5)The entire purpose of DRDO is to fulfil the requirements of forces - When forces need self driving cars, DRDO will make that as well. The "D" in the DRDO is for Defence, other labs in India do other stuff. CSIR has a lot of innovative projects, look them up.

To clear this confusion
This is one of the sensors of eots,but it is testing for the sensors of eots,all the sensors together provide a seamless unified picture,360 degree coverage ,this is for six quadrants
Amca maws and 360 degree vision uses same sensor like the f35.
Eots is also part of 360 degree situational awareness

tejas mk2 would also have it ,not 360 i think ,but it will have 4 ir sensors + 1 irst on the front
