    Keep in mind that increased thrust and improved fuel efficiency are both needed for real improvements.

    Making an engine twice as powerful alone does not off as much improvement as some might think as aircraft have fixed capacity internal fuel tanks that are designed for the engines available at the time of design.

    Fuel consumption is generally measured in weight of fuel burned to generate the energy developed per hour of operation... if you double you energy produced you double the fuel consumption if you don't improve fuel consumption.

    A case in point was the Yak-38 and Yak-38M VSTOL aircraft... the latter had a more powerful main engine, but because the aircraft itself was a subsonic design and no amount of extra thrust would allow it to be supersonic then the extra power increased take off weight but just shortened effective flight range.

    Extra power with these engines however... with the bonus of internal weapons carriage meaning low drag should allow a boost in super cruising speed extending range and lowering IR signature and expanding flight range and improving the ability to evade or to chase targets down.

    That is perfectly in line with what's been announced by russian MoD before. A small quantity of preserial planes ordered, to develop tactics with and to practice on, before a larger contract (possibly with izd30 engines) is made sometime from 2020 onwards.

    We've seen something similar with the T-14 Armata. Ru MOD buys a small batch to try to finds bug before mass production, fixing the problems now before paying for them later. That's the complete opposite approach philosophy then the one practiced by the Pentagon.

    It makes sense especially when considering the "5th gen" powerplants promised by 2019.

    the video says that the indian version of pak fa (pmf) will be integrated with indo-russian supersonic BrahMos cruise missile....would the russian air force will also integrate the missile with its su30 and pak fa fighters?

    Not really a good idea, however as technology progress, i hope Russia can introduce more improvements to their Own Pak-Fas so any leakage to foreign competitors of some weaknesses that this deal will result to would be nullified

    Export is still export, the avionics packages will still be radically different compared to the domestic.

    Sputnik write up. Note that the infographic in the article is from August last year.

    The 9-A1-4071K cannon for the Sukhoi PAK FA fifth generation jet fighter was developed by the Instrument Design Bureau for High Precision Weapons in 2014 and is an upgraded version of the GSh-30-1 30 mm automatic cannon.

    Weighing just 50 kilograms, the 9-A1-4071K is the most lightweight 30 mm cannon around and is ideal for aircraft. The cannon’s one-of-a-kind automatic fire system enables it to fire up to 1,800 rounds per minute – the best such performance for this type of weapon around. Another thing that makes the 9-A1-4071K so special is its autonomous water cooling system where the water inside the barrel jacket vaporizes as it heats up during operation.

    The 9-A1-4071K cannon can fire blast-fragmentation, incendiary and armor-piercing tracer rounds and is effective against even lightly armored ground, sea and aerial targets. The cannon can hit ground targets up to 1,800 meters away and aerial targets at a maximum distance of 1,200 meters.

    Flight tests of the 9A1-4071K modernized rapid-aircraft cannon were earlier conducted on the Sukhoi SU-27SM multirole jet fighter. Military experts believe that the latest targeting systems used on the T-50 PAK FA planes will dramatically improve the efficiency of aircraft cannons, which in some cases are way more preferable, compared to expensive missile systems.

    I think the gun of T-50 will fire new 30mm ammunitions with plastic-driving-band and higher heat resistance primes that has just come into services recently. Firing new ammos, the gun muzzle velocity increases ~7% while the gun's combat readiness is 3 times higher. Besides, the new gun can eject completely all empty cartridges in any combat modes (upto 9 g-load?).

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

    So I've been reading some old threads on other forums & found this vid (presume been posted here before)

    And you really gotta say if it can do this on the 'weak' initial engines holy crap what will it be doing on the proper ones What a Face

    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.

    Huh, I knew pics with tanks were very rare, didn't sink in they are actually 0  Shocked
    It's quite shocking that they have that much range entirely on internal fuel while western planes are hardly ever seen without 2 or 3 huge tanks in any realistic load.

    I know I've seen Su-34s carrying a big centerline tank fairly often & Su-33 has the buddy fuelling pod so they must have a wet centerline, what about Su-30sm & Su-35?

    Su-34 is the only of the Flanker family which can carry external fuel tanks.

    It was my understanding that pretty much any Flanker with inflight refuelling probes can carry the buddy refuelling pod and external tanks.

    The vast majority of inservice Flankers are Su-27s which generally fly with half their internal tanks empty so external tanks are not even considered important...

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