MW: having received a new engine, the Su-57M will be equal in speed to the MiG-31

February 4 2024 54

From 2025, the Russian Aerospace Forces should begin to receive an improved version of the fifth-generation fighter, the Su-57M, which has been undergoing flight tests since October 2022 and will be equipped with a new engine, the AL-51F. Military Watch wrote about this on February 3, providing some details of what was happening.

Although the Russian fighter aircraft industry has consistently missed its stated forecasts for the introduction of new systems into service, the Su-57M will almost certainly begin deliveries before 2027

- says the publication.

At the same time, experts predicted a significant increase in the maximum and supersonic cruising speed of serial multirole fighters Su-57M after they began to be equipped with afterburning turbojet engines (TRDDF) AL-51F, with a thrust of 18000 kgf, which at the development stage were called “Product 30”, and then “ Saturn-30", instead of AL-41F1, with a thrust of 15000 kgf. As a result, the total thrust of the Su-57M will be 36000 kgf (2 engines), which will ensure an increase in the thrust-to-weight ratio at normal take-off weight with a fully filled fuel system from 0,93 to 1,17 kgf/kg.

This provides the possibility of high-energy maneuvering with a steady turn in the pitch plane with an angular velocity of the order of 27-30 degrees / s, which will give the Su-57M additional advantages in close combat (“dog dump”) in conjunction with a thrust vector deflection system, digital emulsion drive, load-bearing layout of the body and developed aerodynamic swells at the root parts of the wing. Moreover, the maximum speed can increase from 2550 to 2950 km/h, which will compare the Su-57M with the MiG-31BM interceptor. The AL-51F engine will increase the flight range of the Su-57M fighter by almost 10%. The rate of climb of the Su-57M will also increase from 330–335 to 370–375 m/s, which will allow the fighter, equipped with Izdeliye-180 and R-37M air-to-air missiles, to quickly occupy a flight level of 13500-18500 m to destroy airborne aircraft. targets at maximum distances of 180 and 250-270 km, respectively.

  The Su 35 accelerates to 2550 km/h; the Su 57 has a more powerful engine, and in terms of drag it surpasses the Su 35. So perhaps it can accelerate to such speeds.

Two-engine heavy aircraft have outlived their justifications - survivability, the need to carry heavy equipment, fuel for 2 engines, etc. . With new powerful engines, the transition to single-engine engines is inevitable, this is facilitated by many conditions of modern aircraft construction - lightweighting of many systems, increasing stealth, etc. Also today it becomes necessary to replace manned ones with unmanned ones with artificial intelligence controls. Over the long decades of building the 5th generation aircraft, the weapon concepts have changed, but our Defense Ministry is just being introduced and is already practically outdated (How long does it take to manufacture the F-22, F-35), and for the near future the need for new concepts is obvious..

  you can replace two Su57 engines with one, 2 times more powerful engine (36 tons of thrust), but “what for the goat button accordion?” and then make a weak engine for a light fighter? and then they developed one engine (a very expensive and time-consuming pleasure, and it’s not a fact that the output will work at all) and it can be installed on both a heavy and a light fighter.
  a heavy fighter has a larger radius, carries more missiles (can lift a heavy Onyx-Brahmos Dagger), a light one is also needed, it is cheaper, more numerous, works on the front end, repelling a massive attack. Su75 (57) without a pilot (with AI) in conjunction with slave UAVs (carriers of additional missiles) this will be the 6th generation. the concept is the same as in the West, the work is still going on, the main thing is that the GDP personnel don’t all disappear later, he himself has long been unable to distinguish traitors from patriots.

  Don't confuse soft with warm. The Mig-31 is an interceptor fighter with the appropriate weight and size characteristics, and the Su-57 is a multirole fighter. When designing an aircraft in accordance with the purpose of the aircraft, the desired parameters and limitations are laid down. By the way, in afterburner the Mig-31 consumes 1,9 kg/kgf per hour to accelerate to 3000 km/h.
  The Su-57 will certainly be more economical and, what is not unimportant, much more inconspicuous. So hello to the Soviet designers and of course respect for the aircraft that was ahead of its time.
  In general, you can put a cow on a rocket and give it a second escape velocity...

What might the enemies know about our super secret plane and engine?! Only what we allowed them to know. So they have only conjectures and fairy tales. Maybe they will tell us how many Su-57s were delivered to the troops this year?
I would really like it to be 24, or even more, 36!

su57 cannot match the speed of mig31, it’s just that the canopy and composite casing will not withstand the heat (400-600 deg). but in general, theoretically, you can make a Su57 with a heat-resistant canopy casing (heat-resistant thick glass with cooling) and get a super fast interceptor (faster than the sr-72 spy). but it won’t do this, because it seems like MIG has been working on Mig41 for a long time.

  Replica. There was such a Harier, the first attack aircraft with the possibility of vertical/short take-off and landing, produced since 1967..., it was not from it that the subsequent Yak-141 was made, because the aircraft was developed since the mid-1970s and made its first flight in 1987. Here, more often than not, ours came second in aviation. Of course, there were some of our own developments, but, as a rule, only a few.

Why does he need such speed? No country in the world is chasing such speeds - the Americans even removed their intelligence officers.

Judging by the guesses about the stealth coating - after maximum speed, the stealth coating will have to be changed... and maybe something else...
And so, yes, it is certainly possible, during a descent-dive, for example, to go home at speed, and then have the plane repaired later...

In fact, the chemical composition of the MiG-31 hull is: 50% steel, 33% aluminum alloys and 16% titanium, therefore (for now) the steel hull of the Su-57 will not withstand such a load, because not designed for this.
