    Meh…the flight of 20 year old technology isn’t all that impressive 😉

    By far the biggest news of the week was this:

    tss.. subsonic garbage

    Seems this inlet has some secrets

    Human habitation puts too many performance and cost constraints on an airplane.

    • The pilot and ejection seat add weight. More weight = less performance.
    • The crew station adds volume and weight because it must be pressurized.
    • The power and environmental control systems have to be enlarged to keep the pilot cool on the ground and warm/pressurized at altitude.
    • The pilot requires displays, controls and lighting that enlarges electrical and cooling power requirements.
    • Enlarged power requirements sap power from the engine(s) reducing range and available thrust.
    • The canopy/windows increase RCS which reduces survivability.
    • The human can only maintain vigilance for about 10-12 hours before becoming too fatigued and committing mistakes. This limits the endurance/range of the airplane.
    • The pilot cannot withstand high Gs or continuous buffeting, limiting maneuvers and choice of flight paths.

    How much does this take? 500-1000kg? for a high performance aircraft of 14000-20000 kg?

    The pilot cannot withstand high Gs or continuous buffeting, limiting maneuvers and choice of flight paths.

    For sure you are one of these guys who think a 14-20 tons aircraft will sustain 20gs because will be unmanned?

    Maneuvers or flight paths are way more limited by the airframe strength and aerodynamics than by the pilot resistance

    Pilots are still important, and will be, for a long time

    Real time decisions are important…no machine/remote control can fulfill this important role

    The canopy/windows increase RCS which reduces survivability

    This is probably the most childish justification

    “This is the newest engine, and not advanced analog power plant for the Su-35, as written, some media and said some” experts. “He meets all the requirements that have been presented to us by” dry “- Fedorov said.

    So the engine of the pakfa is ready?

    I’m more interested on this mysterious engine than in the pakfa

    Jesus….

    At best both the pakfa and the 22 have 0.1-0.5m2 as average frontal RCS

    *********

    One can see in the picture that one pod is full yellow and other is gray-yellow, i’m confused, because yellow is the color of the anti corrosive paint, and gray could be the primer, so hard to figure if are composites or not

    Any released data about it weight?

    Wonder what will happen to the European international arm’s market

    Russians are stealing orders from France’s customers

    But then, Russia and France are cooperating in common programs aswell

    Hope both, russia and france will join together in other fields, i think the pakfa is an imminent threat for the france’s industry…would be interesting if france joins the pakfa program…but this is just a dumb dream

    The main cost for the development is still the engine

    The main headaches in middle program are still structural issues

    If you think the F-35 is threated because some bytes you are wrong, what can kill it is it structure or it engine, not some cool terabytes.

    You are living in a scifi novel

    Please, if we are talking only about the airframe, designing a new one is much less expensive that doing a technological leap in avionics

    Exactly.

    Both of you are so wrong…

    the main headaches for aircraft programs were always in this order

    1) Engine
    2) Structural design
    3) Aerodynamics
    4) Avionics

    Or ECM pods?

    Is there any report of the size/weight of this aircraft?, to tell the true, these engines seems big compared with the AL-31 ones on the Flanker, since both planes are using more/less the same engine, i think this plane is actually smaller than the Flanker, but then it could be just me.

    Looks like they went for reduced RCS to me rather than going whole hog in the stealth department.

    At least, for the frontal RCS this plane looks better than the 22 and 35…just in it shape, a flying wing configuration, a well placed bomb bay, aligned surfaces and much smaller tails

    Rear hemisphere RCS reduction is a no sense if the engines are actually exposed, even the 22’s engines are exposed, don’t confuse the 80’s flat TVCs fashion with RCS reduction.

    Would be a no sense to stuff inefficient nozzles and to denie the 3d TVC advantages , just to follow the garbage that is written in some books…

    Anyways, what are these pods under the LERXs?

    The wing seems to have a high swept, and what are these canards or big slats?

    Any top view?

    perhaps aesa will makes sense to you when your favorite plane gets it

    Aesa jammers makes sense

    Aesa radars used as jammers don’t make any sense 🙂

    aesa can use multibeams by using small groups of transmitters in the antenna

    AESA technology can be used for jammers, this does not mean that an AESA radar is a jammer, same as any other technology

    Ok, i will put some hints, probably some of you will do some research, and learn that your holy AESA is not that holy..

    With AESA, you’re not talking about just 1 beam though,

    Same for PESA, but for detecting and radar matters is always 1 beam

    Just as emitter, yes, it can be split on a couple of beams, just as PESA…but then nobody is claiming for super PESA radar-jammers, everything has it function, everything is designed to work at best in some fields…

    which is why it’s not a dumb idea. Additionally, the speed with which an AESA scans, changes modes/freqs makes multitasking transparent to the pilot.

    Same speed for PESA

    You are wrong
    I won’t explain
    I don’t really care
