Su-57 Stealth Fighter: News #9

Looks more akin to the MiG 1.44

I mean the Canard configuration is there but most of the body, LERX area, engine area, and area behind the cockpit look similar to the Su-57.
I'm glad they never went for the canard configuration and went for something more ahead of the times.

The levicons seem to have all the advantages of canards but without their problems... a thoroughly superior solution.

But this is a wind tunnel test model and that is what you do with test models... you test different ideas and solutions to see what works best.

Yeah, in a documentary they did say that the moving LERX had the advantages of the canards but without the drawbacks.

Last time i checked, TsAGI had more than 28 different models for the su-57s configuration and the total test number exceeded 32 thousand.

Nice find Arrow

Looks like it's two types of the same stealthy attack "drone". The S-71K is for attacking static targets and the other version - the S-71M is an AI version that can seek, identify and attack it's own targets.

The Russian Ministry of Defense has given the go-ahead for production of the S-71 air-launched UAV, the design of which has recently undergone significant changes, taking into account the experience of the Air Defense Forces in Ukraine.

Based on the publication of the Sukhoi Design Bureau dedicated to its foundation in 1939, the following is known about the munition. The S-71 exists in two versions. One version, designated S-71K (codenamed “Carpet”), operates as an air-to-ground guided missile, while the other is a more advanced and autonomous UAV, the S-71M (“Monochrome”).

Sukhoi says it has modified the current S-71 design, compared to the original 2019 specification, to increase its range and reduce its radar signature, based on the experience gained in Ukraine. The design bureau was also forced to abandon its original goal of creating a multi-purpose system and simplify the design to facilitate mass production of this munition.

On April 18, the company began testing the S-71 at Russia’s Zhukovsky Flight Research Center near Moscow. Sukhoi’s chief test pilot Sergei Bogdan made the first flight with the S-71K and S-71M UAVs suspended under the wing of Russia’s newest Su-57 fighter jet.

The S-71 has a trapezoidal fuselage for stealth, with folding swept wings and inverted V-shaped all-moving stabilizers. It is powered by a single TRDD-50 turbofan engine, which is used in systems such as the Kh-59M and Kh-101 air-launched missiles.

The S-71 has a rear air intake and can reach speeds of Mach 0.6 and operate at altitudes of up to 8,000 m.

The S-71M is equipped with electro-optical sensors that provide day and night operation, as well as a thermal imager. This combat platform can also search, detect and engage targets using guidance data stored on board the carrier. Sukhoi claims that the system can be used by the operator in real time for targeting. Among several warhead options, the S-71M can be equipped with a high-explosive shaped charge.

In turn, the S-71K is known to use a cluster warhead.

The S-71K is designed to be launched from external hardpoints of the carrier aircraft, while the "M" version can also be placed in the internal weapons bay of the Su-57 fighter or the S-70 Okhotnik attack drone.

Looks like a Kh-69 with a modified tail.

The wings are the same... interesting that the rear seems to be optimised to reduce radar signature from the ground.

(note like teh glide bombs this missile is upside down on the pylon and would do a roll of 180 degrees so those folding wings on the bottom of the missile when it is on the pylon are on top when the missile is flying to its target.)

Nice.

That talk about single mission planes seems to be reflected in drones with the new Grom drone being less designed for stealth and more designed for speed and external and internal payload...

Here is the Grom for 2021:



And here is the 2024 Grom:

New capacities have been put into operation at the Komsomolsk-on-Amur Aviation Plant

At the Komsomolsk-on-Amur Aviation Plant of the United Aircraft Corporation, new facilities have been built to develop the production of fifth-generation Su-57 aircraft.
The fuel system development buildings have been put into operation, and the first stage of construction of the hangar for development of on-board radio-electronic equipment (avionics) has been completed to scale up serial production of aircraft.
The construction and equipment of new facilities was financed by the United Aircraft Corporation.
Further development of production is also planned. In particular, a hangar for systems development and ground testing of the Su-57 will be put into operation.
"Our task is to put this building into operation as quickly as possible, since the next stage is planned to be the reconstruction of the existing hangar for testing aircraft systems. It is also planned to...

So based on some sources, China already produced at least more or less 300 units of the J-20

From some of the opinions I gathered, Russia is still kinda reluctant to ramp up Su-57 production because its intended engines are not yet fully developed, I think this is a weak reasoning, Both the US and China are building up their inventory of 5th Generation aircraft, Russia cannot afford to wait, There is already an interim engine that can be used for the Su-57, use that at the moment, whats important is that mass production of airframes are started Asap so when the izdeliye 30 becomes ready the production is up and running.

Russian mic needs to get it's act together and make the flat nozzle su-57m right now I'm not getting any younger wtf

ancelot Today at 2:43 pm The Su-57M has several improvements. All new large screen cockpit, electrical actuators instead of hydraulic ones wrote:

It seems the F-35 had electric actuators from the start instead of pneumatic actuators?

A flat nozzle is not needed by the Su-57M.

The Su-35 is proving to be a formidable fighter and the MiG-31BM is also a significant force multiplier. So they are taking their own sweet time with ramping up production. wrote:

Of course, these are great planes, and the R-37M increases their capabilities even more. There are over 120 Su-35S alone, plus the Mig-31BM, which will be around 100. This is not much for the surface of Russia and for an Empire and Superpower. The EU alone has over 500 EFs. Of course, it is known that many of them are unfit for flight. NATO as a threat must be considered as the entire EU plus the USA.

More than likely numbers will mostly be Su-35 and Su-57 with Su-34 being a workhorse for dropping bombs and MiG-31 for long range.

Not forget Su-30 but I don't know if they will buy more of them and just simply upgrade them?

From some of the opinions I gathered, Russia is still kinda reluctant to ramp up Su-57 production because its intended engines are not yet fully developed, I think this is a weak reasoning,

Even if it used the first stage engines it is still superior to any western aircraft or proposed for service entry in the next 10 years.

With the newer engines it is even better.

Worst case scenario they delay the engines for 4 years... it doens't matter... the first 76 fighters will be excellent fighters without the improved engines, and once the new engines are fully serially produced they can replace the older engines in the first 76 aircraft when their engines need overhauls or replacement.

It is the same as with the MiG-35s with AESA radars... if they are not put on the first produced aircraft they can be retro fitted later as their technology matures and becomes affordable.

The point is that if you wait for this or that to be ready then you will never make the damn things because there will always be something new they can add.

Both the US and China are building up their inventory of 5th Generation aircraft, Russia cannot afford to wait,

The conflict in the Ukraine showed how quickly aircraft can be removed from the skies... I would say production of SAMs and production of new aircraft makes sense... making thousands of fighters would be expensive if they are all Flankers or 5th gen fighters.

A mix of lighter cheaper types and drones as well as the more expensive and capable types makes the most sense along with air defence systems that could effectively close airspace to western aircraft.

The Su-35 is proving to be a formidable fighter and the MiG-31BM is also a significant force multiplier. So they are taking their own sweet time with ramping up production.

They seem more interested in getting these aircraft right rather than in service in enormous numbers like the US is with the F-35.

Having enormous numbers of F-35s in service is likely what is going to destroy HATO just on operational costs alone.

Flat  nozzles are supposed to be more stealthy than round nozzles, but AFAIK that is mostly due to turbulence created when the inner super hot gas going through the turbojet core is mixed with the larger volume of turbofan gas that travels around the outside of the turbojet.

Thrust vectoring nozzles probably do the same thing of more rapidly mixing the airflows while also giving an outstanding manouver boost.

It seems the F-35 had electric actuators from the start instead of pneumatic actuators?

Electric would be lighter and less flammable than hydraulic, but being new there will need to be a lot of testing...

Of course, it is known that many of them are unfit for flight. NATO as a threat must be considered as the entire EU plus the USA.

A fight against Ukraine is a small conflict... a fight directly against HATO is a fight for survival the difference in options for weapons used would be significant... western satellites and recon aircraft would not last long and when blind they will be rather less potent... those R-37s will be ideal for taking down AWACS and JSTARS and even inflight refuelling aircraft that HATO depends on.

Whether they shoot them all down or just some and the rest run away the effect will be the same.

That is only for aerodynamics... there are no engines, no underside... this is a very early prototype that likely is as much to test out expected Su-57 flight performance as it is to create a new european fighter...

Of course there has never been a European fighter... the closest they probably got was the F-16.

The closest they will likely get will be the F-35 which many will buy because although bad at least it is flying.

There is no flat nozzles in J20 or F35. Flat nozzle reduces thrust 10%-15% and are not compatible with 3D thruat vectoring. Benefits just won't override deficiencies.

It must be understood that looking amazing trumps efficiency. All joking aside I believe you are right but there was a report from sukhoi where they said they had found a way to use 2d flat thrust vectoring nozzles without hurting efficiency too much. Not sure how true the info is but I do remember something to this affect.

EF , Rafale.

And how many European countries bought those planes?

How many operate F-16s in Europe?

The F-16 is more of a European fighter than the EF or Rafale or Gripen or Harrier or Tornado.

Unlikely Sukhoi did it... more likely an engine maker, but realistically flat engine nozzles would only be useful in drones and strike platforms where manouverability is less important than stealth... but I think we have seen in the Ukraine that stealth wont save you...

This does not change the fact that Europe has about 700 EF and Rafale in total. Not enough? Of course, it is known that some of the EF are not airworthy.

The original NATO F-16's for Belgium, Netherlands, Norway and Denmark were very basic F-16A/B's and the program was approved in the late 70's to replace ancient Mirage 5's and Starfighters. They were eventually modified to BVR capable AM versions. It was only much later that Turkey and Greece joined the program with more advanced versions (F-16C/D).

The even more advanced Eurofighter and the Grippens also came years later, replacing mostly later gen fighters like the Tornado F3's, Mirage F1's, F-4F's and Viggens.

All of the above became very successful EU programs to replace their obsolete fighters.

600, not 700.
Of which 15 have crashed.
680 is a total number to be delivered by 2035.
Of which half is nonoperational.
Or 3/4 of them, if we apply German statistics to the whole of users.
