I mean at least they did not cancel their loyal wingman drone project and have production plans for it unlike another country

They are working on PDEs? I believe the only aircraft to do that for few seconds was SR71. That is interesting indeed.

Sr-71 used a turboramjet engines. This field seems to be pretty highly explored.

Russia tested a model of detonation engine for the missiles of the future - Russian newspaper (rg.ru)

Is it possible to use a detonation engine in hypersonic missiles?

Petr Levochkin: Both can and should be. At least because the burning of fuel in it is supersonic. And in those engines, which are now trying to create controlled hypersonic aircraft, the combustion is subsonic. And that creates a lot of problems. After all, if the combustion in the engine is subsonic, and the engine flies, for example, at a speed of five machs (one wave equals the speed of sound), it is necessary to brake the oncoming air flow to sound mode. Accordingly, all the energy of this braking passes into heat, which leads to additional overheating of the structure.

And in a detonation engine, the combustion process is at a speed at least two and a half times higher than the sound. And, accordingly, by this magnitude we can increase the speed of the aircraft. That is, we are not talking about five, but about eight mahas. This is really achievable today the speed of aircraft with hypersonic engines, which will use the principle of detonation burning.

Rostec Tests Demonstrator Engine for Spaceplanes | Aviation Pros

The United Engine Corporation of Rostec has completed the first stage of testing a demonstrator model of a pulse detonation engine, which in the future can be used in advanced rocket and space systems, hypersonic aircraft and orbital spaceplanes. In some operating modes, the power plant demonstrated up to 50% increase in specific thrust when compared to conventional engines.

Pulse detonation engine is a new type of aviation power plant. It has a more efficient thermodynamic cycle than currently operated gas turbine engines. The A. Lyulki Design Bureau (branch of PJSC "UEC-UMPO") has formed a separate development project for power plants of this type.

“The first stage of testing the pulse detonation engine demonstrator has been successfully completed. It has shown the required performance characteristics. In some operation modes, the specific thrust was up to 50% higher than the performance of traditional power plants. This will prospectively increase the maximum range and payload mass of aircraft by 1.3–1.5 times. The design will be able to be applied, for example, on orbital spaceplanes, supersonic and hypersonic aircraft, and future-generation rocket and space systems," reported the Rostec aviation cluster.

Aircraft equipped with pulse detonation engines will have better flight dynamics and maneuverability. The engine type can be used to develop traditional rocket and air-jet propulsion systems or their support systems.

“The simplicity of the design and its relatively low requirements for gas-dynamic process values allow us to integrate solutions developed on the previous engine generations. This provides a great commercial and economic advantage in comparison with the more traditional engines that are currently under development," said General Design Director of A. Lyulki Design Bureau Evgeny Marchukov.

In 2016, the authors of the "Pulse detonation engine" project became the winners of the "Best innovative project in the areas of critical technologies in the Russian Federation" competition in Skolkovo. A model of a pulse detonation engine was first presented at the ARMY-2017 International Military-Technical Forum.

As reported earlier, this year the UEC holding company of Rostec State Corporation started serial production of the new domestic PD-14 engines for MS-21 airliner, and also began manufacturing prototypes of VK-650V engine for Ka-226T light helicopters.

Did India commit a mistake by withdrawing from fgfa program looking at the progress made by su 57 during recent years? Just a naive question.

See by not going for fgfa we have delayed the induction of 5th gen jet by ten yrs, earliear it was around 2021-22 now it will happen arount 2032. But at the same time it has given our own aerospace industry time to grow and mature to a certain extent, which is very cruicial.
IMO whether it is a mistake or not is totally dependent on succes of AMCA in a given time limit.
by refering to time I think that you can understand what I am pointing at

No, because we can buy it if it is proved to be good product...
Russians will never say no to money, ever!

Even the Russians does not have the final ultimate spec version yet. The production is abysmal.
It will still take half a decade to get the famed Item-30 engine which will actually bring it to western level of performance.
We did not lose anything by withdrawing from the program. They would have hardly shared any TOT with us for all critical systems.

Please find me any western engine that you think is better than the izdelie 30, I will be waiting on your response.

Do you even have the engine ready and working in any prototype?
Fanaticizing about an engine which is supposed to be equal or better than already existing engines from West!

if engine is not ready then what about that su 57 flight trials with izdeliye 30 ??
