00:00May I have a word, sir?

00:07Sure, what is it?

00:08Sir, how many episodes are you planning for the Su-57 series?

00:12Quite a few more, actually, because, well, the aircraft is very peculiar,

00:18and the hardware is little known, so there's not much stuff that I can give for granted.

00:23You may be interested to learn that one of the voice-activated coffee machines in the canteen

00:27of the upper floor of the Sun Hoi Bureau design office uses...

00:29No, no, this has to stop, you will end up getting in trouble, actually, no,

00:35I, I will end up getting in trouble because nobody will believe that you did it yourself.

00:41Is there any electronic device in the world that you're not connected with in any way, shape or form?

00:49Of course, sir. I have no acquaintance whatsoever with the clipper you used to cut your pubic hair, sir.

00:56This is the third episode of the series dedicated to the Su-57,

01:07and in this episode we will start discussing the avionics and the systems.

01:12The previous episodes were about the general configurations, the aerodynamics and the propulsion.

01:17And if you didn't watch those videos, there will be links above and there will be links below.

01:23The Su-57 for the Russians is a quantum leap.

01:28According to the designers, the system is entirely modular with a data bus connecting all the computers.

01:35I have found no mention of an open architecture in the same way it is used in Western designs,

01:42but I would not be surprised if the Russians had defined a minimum interoperability protocol,

01:50because that would just be the logical thing to do.

01:53Why it would be? Because an open architecture would allow for software updates

01:59without having to recertify and retest everything.

02:03Updating the software or adding a component would just be similar to what you do on your computer

02:10when you install a new application or you connect a new piece of hardware.

02:15Well, it's not that simple to be honest, but I think I got the point across.

02:20Always according to the Suhoi Bureau, the plane has a lot of spare room and a lot of spare electrical power

02:27for new or upgraded systems.

02:30It has been designed with upgradability in mind.

02:34This is a favorable condition for the longevity of the aircraft,

02:38but also to accommodate any particular requirement that an export client may have.

02:45The interaction between the pilot and the aircraft is managed by what the Russians call an IUS unit.

02:56Well, it can loosely be translated as Information and Control System.

03:02The computer has been designed by Suhoi itself, without relying on the usual Suhoi supplier, the RPKB from Ravenskaya.

03:11The reason for this is that Suhoi wanted to go with the best possible system that they were able to build.

03:19They decided to make no compromise on the system technology.

03:24The concept that they have followed is called Intellectual Assistance.

03:29With this term, the Russians describe the process of presenting the pilot with only the relevant information

03:36for that specific flight condition,

03:39or the automation of all the tasks that are better and more precisely executed without human intervention.

03:47Up to 90% of a mission can be flown automatically,

03:52with the pilot manually flying the plane only during take-off and landing.

03:58The mission can be pre-programmed, like the Russians like to do, particularly for the air-to-ground domain,

04:05but obviously the pilot in flight can change everything, can set new waypoints,

04:11change altitude and speed, choose flight profiles and so on.

04:16In this way, a large part of the pilot's attention can be focused on the mission itself.

04:23Some may say that this approach might reduce the amount of training required to effectively fly the plane,

04:32but I personally don't believe that they are going to go down that path,

04:37because it may be very very dangerous and may go wrong very very quickly if things do not go as expected.

04:48We know that at least one test of automatic flying has been successfully conducted,

04:54with the pilot just sitting in the cockpit as a spectator.

04:59However, we don't know whether this is going to become an operational feature,

05:04useful for example for high-risk suicidal missions.

05:09While honestly it doesn't seem very likely,

05:12but many of the 6th Generation Fighters projects currently ongoing do include this optional in-mand feature,

05:20which I'm still struggling to really understand if it could be useful in a real conflict, in real operational conditions.

05:32However, there is at least one case in which it could really be useful,

05:36that is taking home a wounded or an unconscious pilot.

05:42The Sukhoi 57 has one of the richest sensor suite ever installed on a fighter.

05:49Actually, Piotr Butowski in his book on the Sukhoi 57 Phalan has a really interesting picture

05:58that summarizes all the systems installed on the aircraft, but yeah, I'm afraid I can't use this in the video.

06:08We will cover this in detail, but for now what's important to understand is that a lot of sensors means also the risk of information overload.

06:20So sensors and information fusion is an essential feature to assist the pilot's job.

06:27This function in the Sukhoi 57 is performed by the IUS.

06:33So the pilot while not flying the plane can automate the target search,

06:38the attack profiles, the kind of firing solutions that are chosen.

06:43I believe this could be really useful, but could also be a double-edged sword.

06:48The standardization of combat procedure in case of a generalized and prolonged conflict,

06:55it is a vulnerability that can be exploited by the enemy.

07:00So during a long conflict, during a long period of time, and for long I mean more than a few days,

07:09it may be necessary to actually vary these procedures and these policies in a way that is not easily understood by the opponent.

07:21The Sukhoi 57 obviously features a secure data link, which we know very little about.

07:34The Russians have quite an important experience with long-range data links, which are necessary for a country that has the size of Russia.

07:43However, we can expect the Sukhoi 57 to be quite capable, even though we don't have any specific information.

07:50The reason is that we know that tactical experiments where the Sukhoi 57 was acting as the quarterback

07:59for the previous generation Sukhoi 35s have been conducted.

08:06Yes, that's exactly the same function that the F-35 is supposed to perform together with the F-16s and the F-15s.

08:16We don't know the result of the test, but if the plane is interoperable with Sukhoi 35, we know that the Sukhoi 35 data link is quite capable.

08:26For example, the commander of a Sukhoi 35 formation can physically provide the other plane's weapons with the firing solutions,

08:38leaving the other pilots in the flight the only task of materially pulling the trigger.

08:45It only seems logical that this kind of centralized command is implemented on the Sukhoi 57 too.

08:52A further function of the IUS is the automated aircraft self-defense.

08:58An automated system now is quite common, and the Sukhoi 57 features radio frequency jammers, infrared jammers, plus the usual dispensers of chaffs and flares.

09:11Obviously, all of these systems have to work in a coordinated way to maximize the effectiveness.

09:18Anyway, we will cover this in detail in a different episode.

09:25The production Sukhoi 57 has a different cockpit layout than the PAK FA.

09:31The PAK FA cockpit was sort of reminiscent of older generations.

09:38The production Sukhoi 57 is much more modern.

09:41So the general configuration is the classic HOTAS, that hands on throttle and sticks, but there are no analog instruments of any kind.

09:52There is just one large panoramic screen as it is commonplace in the most modern fighters.

10:01There is actually another small multifunction display mostly used for the communication management.

10:08The HUD is probably the largest ever installed on a Russian fighter, but on the Sukhoi 57 it may not be that necessary.

10:21In fact, the pilot's helmet makes use of augmented reality to show the flight information to the pilot as it is appropriate considering the flying conditions.

10:33The HUD information is replicated on the helmet, but obviously the helmet can also be used as the targeting device for the off-board side weapons.

10:44One uncommon feature present on the Sukhoi 57 is the capability of showing the picture captured by the four infrared cameras distributed on the helmet.

10:57If the pilot activates this function, he can actually see through the structure of the plane.

11:03Yes guys, that's exactly the same feature available on the F-35.

11:10However, on the Sukhoi 57 the cameras do not cover 360 degrees and they are used mostly for night navigation and low-level flight.

11:23But this will be the subject of one of the coming episodes where we will dive deep into the details of all the electromagnetic and electro-optic systems that are available on the Sukhoi 57.

11:40That's all I have for now. Thank you for watching and stay tuned.
