    Aren't the Su-27 family/generation known for their huge gas tanks?

    No... that would be the big 3,000 litre PTB-3000 tanks of the Su-24.

    The Su-27 is well known for its enormous internal fuel capacity... for most missions they have half their internal fuel tanks empty.

    That's what I meant, I didn't mean drop tanks.

    Does any one know what is the limited g-load of gun firing on Mig-29 and Su-27 now?

    From memory the only g limit for the early model MiGs was when the centreline fuel tank was fitted and that was a g limit for the tank and not actually the gun.

    Both the Flanker and Fulcrum were designed for dog fighting so I would think there was no limitation in firing the gun except when the ferry tank was being used by the MiG... the Flanker has no wet pylons and so could not carry ferry tanks.

    Thank you Garry. As I remember, some old aircrafts with gsh-23L gun have to limit gun firing in some circumtance g-load maneuvers.

    Soviet had tradition to use available drop tanks for new aircrafts such as using PTB-1150 of Su-17 for Mig-29. They planed to adapt 2,000L PTB-2000 tanks of Mig-31, not PTB-3000 of Su-24, for Su-27. Two such that tanks on wings will help Su-27's feery range extend more 1,000 km. However I have never seen any photo of that load figure.

    There is no light emitted towards the ducts, therefore they are completely dark.

    Engines are angled inwards and are at slightly higher position than ducts so we could not see blades anyway.

    Check some pics from above, it is easy to notice the angle.

    Open it in an image editor & mess around with gamma etc, it's a very flat black in there, with some pretty squared off edges -> almost certainly manually blacked.

    The commander of aerospace forces of Russia, Colonel-General Viktor Bondarev said that the first of a new generation fighter T-50 (PAK FA) will start to arrive in the Russian VKS next year. "Interfax" results statement commander VKS Russia:
    Next year we are completing it (fighter 5th generation) test. In this contract the first five aircraft are included in the cost of the contract. So next year we will start to receive these first five aircraft.

    According to Viktor Bondarev, then begin a large-scale series production of new combat aircraft with deliveries in parts, flight.
    We do not stop getting Su-35, Mi-28, Ka-52. In addition, we will get modernized techniques Tu-95 and Tu-160, which show excellent performance.

    His first flight of the PAK FA performed in 2010 in Komsomolsk-on-Amur. For six years the aircraft was substantially modified, I have found the latest on-board control system not only flight but also weapons. At this point, according to the manufacturer, created six prototypes of flight that are required to perform the tests, taking into account comments from flight crews in performance.

    Interesting. Why MOD isn't in a hurry to get PAK-FA in big numbers? Is it:

    Technical question: They wait for new engines, something else is not ready etc.
    Money question: They go for cheaper variants.
    Speed question: They need to expand AF quickly to counter nearest threats. PAK-FA gonna take time to start mass production, equip bases, create training programs, teach pilots.

    They are not in a hurry to get it into service in enormous numbers because they don't need enormous numbers of them.

    The Su-35 and MiG-35 are entering production and so when the PAK FA enters production they will have three modern fighter bomber aircraft entering service... in fact five if you include the Su-30s or various types and the Su-34s... plus upgrades of existing types including the MiG-31 interceptors and MiG-29 and Su-27/30 aircraft.

    The US has put all its eggs in one basket... replacing all existing types with F-22s and F-35s which will be very very expensive. Russia is making both 4th and 5th gen fighter bombers and so can make cheaper aircraft and more expensive more capable ones too.

    They are not making thousands of PAK FAs because they don't need thousands of PAK FAs... I think the Su-35 is a far better counter to NATO F-35s anyway.

    New Engines, Weapons for Russian Stealth Fighter


    Russia’s T-50 fifth-generation fighter aircraft will enter flight-test with new engines in the fourth quarter of next year. The Sukhoi-designed jet is also known as Pakfa (Russian acronym for Perspective Aviation Complex of Frontal Aviation). More detail about the T-50’s weapons fit has recently emerged.

    The Pakfa has been flying since 2010 on the power of NPO Saturn “Item 117” engines developing 14.5 tonnes (32,000 pounds) thrust and derived from the “Item 117S” engines found on the Sukhoi Su-35 Advanced Flanker. But the new engines are a fresh design designated “Item 30” that has already begun bench testing, according to industry sources. Their thrust is likely to be between 15 and 20 tonnes (33,000-44,000 pounds)

    Speaking to the media last month, Alexander Artyukhov, general manager at United Engine, said that remaining development work on the new engine “will be done in the period of 2018to 2020, with state acceptance trials set for 2020.” Russian industry previously developed a 20-tonne-thrust fighter engine for the MiG 1.42 technology demonstrator that flew briefly in 2000. But it never entered production.

    Meanwhile, a ninth prototype Pakfa has flown and is now undergoing “complex avionics testing” and weapons firing trials. Russian air force commander Gen. Viktor Bondarev told journalists recently that the military is ready to sign a contract next year for five aircraft to be delivered in 2018. Deputy defense minister for equipment procurement Gen. Yuri Borisov said the ministry is going to award an initial order “for at least one squadron” of Pakfa aircraft next year, powered by the existing “Item 117” engines.

    United Aircraft (UAC) president Yuri Slyusar called the Pakfa development “one of UAC’s priority programs.” He continued, “If we succeed with Pakfa development, this will help us maintain competitiveness in the domain of frontal aviation in the long term.” Slyusar expects the initial order to be for 12 production airframes, adding to the planned total of 12 prototypes that would remain with the industry and testing establishments.

    The Tactical Missile Corporation (TRV) recently revealed that it is working on 12 types of missile for the aircraft, targeting completion of trials on six types by next year and the remaining six by 2020. These include new air-to-air missiles: the RVV-MD for close-in combat, and RVV-SD for beyond-visual-range engagements. Compared with previous-generation models, they feature new homing systems with higher sensitivity and resistance to jamming. The RVV-MD employs a new twin-band infrared seeker with multi-element photo-receiver and digital signal processing. These innovations will double the distance of target acquisition compared to the previous-generation Vympel R-73E, while enlarging the missile’s seeking angles by 30percent. The RVV-SD, which is a further evolution of in-service RVV-AE, features improved aerodynamics, a higher-power emitter and a more sensitive active radar homing head than its predecessor. The missile’s software has been “completely reworked” to enable a 35-percent increase in the maximum firing range and improved capabilities in defeating aerial targets by executing 12g maneuvers.

    Air-to-ground weapons slated for the Pakfa include the Kh-38ME missile line of modular designs that allow for employment of different guidance systems and warheads. The Kh-38MLE version comes with a laser homing; the Kh-38MTE with a thermal imager; and the Kh-38MAE with an active radar seeker. There is also a Kh-38MKE version with satellite-aided homing. 

    In addition to the KAB-500SE guided bomb with Glonass homing, which was combat-proved in Syria, the Pakfa may also use the much lighter (250kg) KAB-250LG-E with a similar homing system.

    Furthermore, the Pakfa will carry OFZAB-500 “splinter/high-explosive/incendiary” and the ODAB-500PVM vacuum bomb. Examples of these munitions have been manufactured for testing.

    MiG 1.44 was to fly 3,200 Km/h i wonder if stronger engines will impact also max speed for PAK FA

    The major problem with beyond mach 3.0 speed ,is that the surface of the plane will
    receive too much tension ,that will damage the stealth coating material.So stealth planes
    with coating material , cannot fly beyond supersonic speeds without damages to its coating.

    Abrasive friction and of course heat lead to surface damage... including to painted surfaces.

    New materials are needed... they had stealthy coatings for the turbine blades on the engines in the Tu-160 so it wont be impossible as the air hitting the front fan blades when the Blackjack is supersonic would be hot and fast...
