    Are you guys trying to re-write history ?
    The X-32 was a modern take on the Harrier ?

    If I recall, the Harrier can take off vertically, while the X-32 failed miserably, even over the pit, ie out of ground effect.

    Don’t tell me what the X-32 would have been able to do and how well, as I’m sure a lot of developement troubles would have come up with it also. Don’t forget, the F-35, or X-35, was going to do all sorts of wonderful things also, and for a very low price. How did that work out ?

    The X-32 was a much more compact and dense design and as such, had less growth capability. Its original design with a delta had to be modified to swept with a tail for a more horizontal attitude for carrier landings. And although Boeing assured everyone that its RCS and flying qualities would be unchanged, I don’t think anyone wanted the extra insecurity.
    I also don’t think its RCS was in the same class as the F-35. That big opening at the front had to expose compressor blades and even if a screen were used as a shield ( so I’ve heard ), it would only work for a certain range of wavelengths.

    I suggest you guys re-read the IAPR article in issue #1, and I remember seeing a NOVA program on the JSF competition on TV. It may be available online.

    probably same reason as pakfa. fan blocker design to block specific type of wavelength, but not for other.

    The fuselage of the Su-27, MiG-29, F-14 or PAK FA has high lifting properties, through the tunnel between the engines. Maneuverability, range – better. RSC – worse. This design type as the fuselage F-16 provides ideal conditions for the engines.

    The fuselage of the MiG-25/31, F-15, F-22 is better suited for the aircraft at supersonic cruising speed. Because it has a lower resistance to the speed of M> 1. Load-bearing properties of the fuselage below, maneuverability and range – is worse. RSC – better.

    yes that why all stealth design even f23 has mostly flat bottom. some maybe some bumpiness but only pakfa chose tunnel between engine because they value manouverability over stealth.

    theres pictures not really fair because they are special aircraft.

    ugly oes should be the common airplane a country use

    and most ugly ones usually come from this one country

    The press continues to mention pilot error. Usual sensationalism.

    Source: MAK: Vnukovo Plane Crash Not Caused by Runway – The Moscow Times

    not first time it happen with this plane. other incident with this plane all include landing problem. seem some thing is consistent. bad crew training, bad autoflight system, bad ground control.

    MIG-35 is heavier because it usese 20% more powerfull engines. It has larger nose to accomodate larger radar. and there is no evidence its draggy or short range than Rafale. infact top speed, climb rates (max altitude) with load will be higher for MIG. There is reason MIG-29K is selected for carrier operations. while Rafale/EF influenced obsolete design J-10 not.

    actually rafale is also selected for carrier operations and is in use with french navy. mig35 hneed more powerful engine because the mig is heavier and larger so it needs more power to lift such a heavy draggy airframe. but it cannot supercruise so obviously not enough power like rafale or eurofighter or even gripen. j10 has aesa and modern avionics, can beat mig35 easily.

    what has economic opening anything to do with fundamental research.
    Canards is always late 1970s design. J20 heavily borrowed from MIG MFI. it is not new design.
    see this large canards, wing design, lengthed nose. Every thing you see in J-20 is copied except intake got changed.

    do you ever thought why these planes are not taller from the ground.

    because it mean china economy opens up it has more money and with more money it can put that money in research and airplane production. very very simple. thats why china produce far more aircraft than russia and has more design program going on. manyflankers have canard

    Delta wing has more fuel?. Does EF/Rafale carries more fuel than MIG-35/K despite having slightly larger wing area.
    J-20 wing area dont look larger than Flanker. It will take some time for Chinese to realize that it is unworkable design. I am not going into enormous drage of such platform along with weight penalty.

    mig is much heavier and larger than rafale so it is very very draggy. beause its draggy it has to use more fuel to fly so it is shorter range than rafale. they had to add a spine to it to give it more fuel but it ends up being even heavier and draggier than before, so it does not solve that much problem.

    J-20 is size of Flanker with wing area looks slightly less. Any larger internal bays will come at expense of fuel capacity. and since Stealth fighters are always overweight it will translate into reduce range.

    j20 has big volume inside so no problem on range. also its delta wing so more fuel.

    flanker is really mostly empty. it is just two long engine inlets on the bottom.. the top part only has nose, cockpit and a small spine.

    also the chinese engine promise much better fuel consumption than russian ones it used in the beginning.

    China is not a modern superpower so it always need to resurrect soviet stuff. and it has great difficulty to operationalize newer designs such as L-15 which is 1990s design.
    Tu-22 has many advantages over Soviet era carrier. as it give flexibility of using 5tons to 9tons bombs. with modern avionics upgrade the weight will be reduced by 4 to 5 tons. so it is very modern and efficient design.
    and i wont rule out upgrading it with NK-32 engines whose production is going start not only for aircraft but trains. so there is economies of scale.

    china open up its economy in the 70s but russia had to wait until the 90s when the country crash to open up. so china has 20 year advantage ove rrussia in getting money, new technology, etc, etc. you can really see it in the design of the j20 and j31. they look like modern american 2000 design but pakfa looks like in between flanker and yf23 so somewhere in the 80s.

    I doubt the J-20 would be able to carry ASMs, at least not internally. The weapons bay seems a bit too small for that.

    no, j20 bay is big they can fit some asm in there. j20 design to do almost all role and has the bay to do it.

    it used a radar blocker to mask the engine front, so, not such a big deal…

    and for RCS measurements, nobody here can speak about it with real knowledge about the values, either because nobody knows or because some who do know can’t speak about it publicly anyway

    blocker is bandaid solution thats one reason why x32 lost. not as thorough as sduck which is design ground up to minimize radar returns. if sduck so easy then everyone would make straight through inlet like the flanker and just add blockers. boing value cheap and simple design over front stealth that is why they made it straight through

    “Carry more” is too generalized.. Most cargos bulk out before they gross out.

    that is why y20 is big and wide so it can carry things il76 cant
