    I didn't know that.

    More work destroyed by Technology. I hope they don't fire their skilled workers for 3d printers.

    This is one of the things that have been interesting me about the airplane.
    The skeletonised, organic structure of it's components is a huge deal, followed by making airframes of similar structure in the future.

    The weight savings are massive. Yet it receives very little credit.

    Probably the delay in recognition is trying to work out how to take credit for the idea and copy it themselves so they can say they have been doing that for years but kept it secret to prevent the Russians from copying them.

    Here are some of their earliest designs...

    Why arent more Su-57 prototypes flying with serrated nozzles? Why are russians so afraid of putting them on?

    What is the rush... it will be ready when it is ready...

    The difference in stealth is meaningless because stealth aircraft are not stealthy to Russian radars.

    There doesn't seem any logic to have such a glacially slow flight schedule. At least test the serrated nozzles with the AL-41 more instead of the primitive 4th gen ones which lack any sort of IR reduction features.

    How do you know what IR reduction features they have?

    Serrated nozzles has nothing to do with IR reduction BTW.

    Two-seat Su-57 fighter jet to be designed for control of Okhotnik drones — source. 27.07.2021.

    The fighter jet, already in development, is presumed to control about four Okhtonik drones.

    MOSCOW, July 27. /TASS/. A fifth-generation Su-57 fighter jet will be designed in a two-seat modification to control a swarm of heavy Okhotnik combat drones, a defense industry source told TASS.

    "In order to control advanced Okhotnik drones, a two-seat command variant of Su-57 will be created. The fighter jet, already in development, is presumed to control about four Okhtonik drones," the source said.

    TASS could not obtain an official confirmation of the report at the time of the publication.

    As the press office of Russia’s United Aircraft Corporation (UAC) earlier told TASS, the latest Okhotnik drone will strike aerial and ground targets in network centric interaction with a Su-57 fighter. In their joint employment with the fifth-generation fighter, Okhotnik drones will deal with a full range of tasks, striking aerial and ground targets under the command of a Su-57’s pilot.

    The Sukhoi Su-57 is a Russian-made fifth-generation multirole fighter designated to destroy all types of air, ground and naval targets. The Su-57 fighter jet features stealth technology with the broad use of composite materials, is capable of developing supersonic cruising speed and is furnished with the most advanced onboard radio-electronic equipment, including a powerful onboard computer (the so-called electronic second pilot), the radar system spread across its body and some other innovations, in particular, armament placed inside its fuselage. The Russian Armed Forces received the first Su-57 fighter in 2020.

    The Okhotnik heavy attack drone performed its debut flight on August 3, 2019. The flight lasted over 20 minutes under an operator’s control. On September 27, 2019, the Okhotnik performed a flight together with a Su-57 fifth-generation fighter jet. The drone maneuvered in the air in the automated mode at an altitude of around 1,600 meters and its flight lasted over 30 minutes. The serial deliveries of Okhotnik heavy strike drones to the Russian troops are scheduled to begin from 2024.

    The level of technologies used in the creation of the Su-57. This is the bracket of the main landing gear support.
    Thats an actual production piece for Su-57 not just a 'here is what it could look like if we did it'? Shocked

    If they've actually got that kind of stuff going into production aircraft thats very impressive.

    Well, the truth is that hardly any Russian company presents itself as a supplier of high-quality printing powder.
    There are Muricans, and some Scandinavian-based companies cooperating with Boeing presented as "top of the notch".
    As we know that they produce 3D-printed metal parts for the aviation industry, the question "if" is already answered.
    Russkies can deliver the material, still lacking the publicity.

    Su-57 aircraft are planned to be equipped with airframe monitoring sensors from 2024

    The control system can begin to be installed on fighters from 2024

    MOSCOW, July 28. / TASS /. The system for monitoring the technical condition of the aircraft in real time is planned to begin to be installed on the Su-57 fighters from 2024. This was announced by TASS at the MAKS-2021 air show held in Zhukovsky by Anton Mishachev, the leading technologist of PJSC Sukhoi Company (part of the UAC of Rostec State Corporation).

    "In 2022, we are planning flight tests on a prototype Su-57, and in 2024 we are planning to install the system on a serial product. We worked on it for the Su-57 fighter, but this system can be adopted for any aircraft," he said. he.

    He explained that the built-in control system consists of two types of fiber-optic sensors - strain sensors and acoustic emission sensors. "The system allows collecting data during the entire life cycle of the aircraft. Based on the information received, the aircraft's residual life is calculated - how long it can fly off," Mishachev said.

    The sensors will be installed in critical areas of the aircraft. In the future, it is possible to install them on other models. “It is important for us what the aircraft consists of - the Su-57 is made with the use of composite materials. Acoustic emission sensors will be used for these materials, which allow us to determine the destruction of the material by sound pulses - they read clicks. which allows you to localize the area where the destruction occurred. Also, the Su-57 will use strain sensors. They will be installed on the highly loaded elements of the aircraft, and from them it will be possible to judge the loads on this element ", - said the technologist.

    Mishachev clarified that at present such a system is being tested and is not used during the operation of aircraft. "Thus, in operation, it is impossible to understand what loads were on the elements of the aircraft, how large they were in flights. All flights are different: in some the plane flew smoothly and did not experience heavy loads, and in some it twisted bends, as on MAKS, and, of course, the loads on its units were significant. The resource of these units depends on this, "he explained.

    According to Mishachev, now specialists are optimizing the system and developing a recorder unit that will be installed on the aircraft. The system will make it possible to determine the state of individual zones of the aircraft and take into account the loads on them, which will make it possible to save on its maintenance. The project became one of the winners of the Future of Aviation competition organized by United Aircraft Corporation PJSC and was presented at MAKS-2021.

    Seems compatible with the schedule we know for Megapolis project:

    - New cockpit
    - Izd. 30
    - Apparently, 8 internal missiles
    - Upgraded avionics
    - Airframe resource monitoring
    - Development of new variants

    Some of those above are rather speculative, and probably there are many more improvements that we don't know.

    Do you guys know if we will start seeing izd 30 on new frames in late 2022? I could never figure this out.

    In 2022 it is expected that the tests of the Su-57 second stage will start (that means fully equipped with izd. 30), they should end by 2024 and the first upgraded serial airframes should start being delivered around 2025.

    The art of HR Geiger. He was a seriously fucked-up dude, but his talent spoke for itself.

    Before I looked up those images to post I would have questioned your problem regarding the father of Alien... but looking through the penis wall graphics he designed and some of the other images... yeah... fucked up genius is just about right I think... Embarassed

    "In order to control advanced Okhotnik drones, a two-seat command variant of Su-57 will be created. The fighter jet, already in development, is presumed to control about four Okhtonik drones," the source said.

    The development of a two seat model would be useful for carrier operations too...

    Bzzt. Wrong. I posted a link to description of Kalashnikov's NC machine + 3D metal printer. It can handle
    titanium no problem. The trick is the size of the metal powder particles. Your reference to a bulk melting
    temperature does not apply when fine powders are involved.

    It is funny.... when he mentioned the problem might be that it wont melt, my thoughts were that in powder form there is a real risk of burning or explosions... powdered metals are routinely used in fireworks to create different colour sparks... when reduced to a fine powder most metals burn readily and when thrown into the air powders like flour and metal powder can explode with the right oxygen concentrations...

    As we know that they produce 3D-printed metal parts for the aviation industry, the question "if" is already answered.
    Russkies can deliver the material, still lacking the publicity.

    Well the hint would be the 100% russian origin of parts for the PAK FA suggest that the Su-57 was made from Russian materials from Russian sources... even if they are not available for export on the civilian market yet or if at all.

    Why didnt they test izd.30 earlier given that it passed bench tests more than 5 years ago and it had a flight in 2017?

    Pilots will be able to control the Su-57 using their eyes, the developer said

    The head of the cabin department of the Sukhoi Design Bureau, Dorofeev, said that the pilots will be able to control the Su-57 with their eyes

    MOSCOW, July 28-RIA Novosti. The pilot of the Russian fifth-generation Su-57 fighter jet will be able to control the aircraft with eye movements in the future, the head of the cabin department of the Sukhoi Design Bureau told Arsenal of the Fatherland magazine. Nikita Dorofeev.
    According to him, this area of development of the system has potential.

    "It's a complicated thing. The pupil of a person is constantly moving, scanning space. This is done unconsciously, we don't even notice it ourselves," the expert added.
    Nevertheless, there are already prototypes: after a short training session, you can press buttons with your eyes, select display frames — they are displayed on multifunctional screens in the cockpit of the fighter. At the same time, the expert noted that while the system works well on the stand on the ground, and "in flight, everything is much more complicated."
    Another option for developing the Su-57 interface is voice control. Now, as Dorofeev explained, the problem is being solved, how to teach the system to understand not memorized phrases, but the context, so that the pilot in extreme conditions does not remember which words he should say.
    The head of the cab department also spoke about touch screens that will allow you to create a multi-layered display, make it interactive and more informative, as well as augmented reality.

    "For example, when in conditions of poor visibility on the same indicators (in the cockpit of a fighter) or on the helmet-mounted target designation and indication system, the terrain, lane, and other ground objects are drawn. Civil aircraft already have similar systems, " the expert explained.
    This, he said, may be necessary to represent the target situation or in conditions of poor visibility. The augmented reality system will be combined with a technical vision system — optical cameras, including in the infrared range, located in various parts of the aircraft. For example, in conditions of haze over the terrain, they will provide the pilot with better visibility.
    The Su-57 is a fifth-generation Russian multi-role fighter developed by Sukhoi. It is designed to destroy all types of air, ground and surface targets. The aircraft has supersonic cruising speed, in-fuselage armament, radio-absorbing coating, as well as the latest complex of avionics.
    By the end of 2024, the Russian Aerospace Forces should receive 22 Su-57s, and by 2028 their number will reach 76. The first production fighter was handed over to the Russian troops at the end of last year.

    They have not stopped flight testing at the LL since 2017... creating a world-beater engine seems to be a non trivial task Razz

    There have been less than a dozen flights, and none with 2 izd.30.

    Serdyukov reported 16 flights a while ago, and in general they test what they want, how they want. I don't think we get much about the test program of izd. 30
