Russian Su-57 Aircraft Thread (PAK-FA and IAF FGFA)

I think it is supposed to be the stealth bomber drone recently unveiled. The presence of the logo may imply that the Su-57 can remotely command other drones.

Yup! Now I get it. The drone on the tail logo as well as the digital camo pattern was a good hint along with recent images of the stealth drone.

This is bad news for RSK Mig.
Sukhoi is selling a lot more than Mig and they just won the heavy drone adquisition program.
I don´t know how hard this blow can be for Mig as a company.
The Mig-35 is a good plane but almost as expensive as the Su-30 that is bigger and has a heavier punch.

These are hard times for an historical company.

OT:

MiG missed the boat by not going ahead with a low cost a single engined fighter for export. Chengdu saw the opportunity and went ahead with the FC-1. CAC even had consultations with MiG because of their experience in the Mikoyan "Project/Product R-33" after the US sanctions on the Super-7.

I think they did not have enough internal funds to develop a whole new airframe. MiG has really had tough luck after the fall of the Soviet Union. The MiG-29 upgrades did not sell well, the Skat was not funded, the MiG-AT got cancelled in favor of the Yak-130. Plus with the delays to their carrier program I think they should just disband the design bureau and spread the personnel among the other design bureaus (i.e. Sukhoi and Yakolev) and perhaps reform it later. It would not exactly be the first time this happened. Polikarpov used to be the main designer of combat aircraft in the Soviet Union but eventually his bureau was disbanded.

Other than the vaporous MiG-41 project I can't remember anything else they are meant to be working on. The MiG-35 is, I think, a waste of time.

The PAK-FA should be IMHO part of a high-low combo with another aircraft for cost effectiveness.
But I do not see much chance of the smaller aircraft happening at this juncture.

There is another way to execute a high-low mix than large + small IMHO, stealthy (Su-57) + non-stealthy (Su-35/Su-30SM) may well deliver comparable savings.

You guys do realize, there is still the Mikoyan LMFS (Liogkiy Mnogofunktsionalniy Frontovoi Samolyet or Light Multi-Function Frontal Aircraft) Project.... right?

Mikoyan's LMFS is supposed to be the "Low" of High-Low mix to the PAK FA / SU-57.

And where is it? It's been talked about at least for 15 years.

An article from Avionics International providing an update on the SU-57 and some insight on its avionics complex.

Some noteworthy text :

Prior to each Su-57 flight, a special flight program is prepared and loaded into the flight management computer. The program comprises intelligence data, information about weapon systems of the target, its coordinates and other relevant data. This program can also be adjusted during the execution of a combat mission at any time .

Seems to be some kind of threat library like that of the F-35

Sukhoi Design Bureau engineers describe the Su-57 avionics as featuring a central computer which controls all of the aircraft systems, including weapons and intellectual support of the pilot. The computer simultaneously performs the role of an electronic pilot, an electronic navigator and an electronic flight engineer capable of automatically recognizing and determining adversaries and targets. In addition, it is capable of planning the most optimal route to an objective.

There is also a control system featured within the avionics which controls almost all of the key systems of the aircraft, including its location, navigation and communication.

Some sort of integrated systems architecture

[“We worked in similar directions with the US designers at the initial stage. However, in contrast to them, we decided not to load the main onboard computer of Su-57 with processing the entire volume of primary data. Currently Su-57’s avionics complex is designed to process just the ‘upper part’ of data package. This allows it to work faster, more reliably and efficiently,” said Gribov.

This seems to be a hybrid sensor fusion architecture between the F-35 (data centrally processed) and the European (Rafael/Typhoon) which is at sensor level and the track correlated centrally.

Data exchange for Su-57 onboard systems are conducted via fiber-optic channels. The fourth-to-fifth generation transition from copper to optical fiber allowed the designers to significantly increase the speed and volume of data transmission, while reducing the weight of the cable network and improving its noise immunity. Whereas data transmission over a traditional copper cable produces a speed on the order of 10-100 Mbit/s, fiber optics is almost 8 Gbit/s.

Seems to suggest the data bus architecture used is equivalent in capability to the IEEE13946 standard as used in the F-35

It might be Ethernet as used in modern commercial aircraft. Or something more exotic like InfiniBand.
I would use Ethernet. It is widely available.
