    The T-50 performed its first flight January 29, 2010.

    wonder how much the plans cost??

    The engine generates a larger thrust and a complex automation system, to facilitate flight modes such as maneuverability.

    Can you say ....pitch axis thrust vectoring....:shrug:

    Second photo is an F-22, not PAK-FA.
    And thrust vectoring isn't fitted yet (although there's plenty of room for 3D vectoring of the nozzles).

    From some angles it's more reminiscent of the YF-23 than F-22. I like it.

    Ah, okay.

    Not yet, but I bet it's on the list.
    Look at the clearance on this pic: up/ down, left/ right: lots of room...

    Nice cut-aways in the tailplane.

    my understanding was that the f22 only has it up and down...not left and right.. for roll

    Yes F-22 has 2D vectoring, PAK-FA will probably (funding-dependent) have 3D.
    The Russians like their manoeuvre ability: MiG MFI/1.44/1.42 had no fewer than sixteen control surfaces plus 3D vectoring.

    did you say 16 control surfaces or what??

    Yep 16 on the MFI 1.44.

    your photo only shows the F-22. Please use the photo for the T-50.

    Although similar in appearence, T-50 has an exceeding in flight capability characteristics than the F-22.

    I wonder thou about how much J-XX will rip off tech. from T-50 or/and F-22.

    By the way I was curious,have these birds just about reached the end of their evolution? If not what more can be done in the future or whats next? Thanks.

    this is the beginning of the evolution of these birds, and by the way we are soon moving from bird designs to insect designs. imagine an aircraft that can fly with the manouvering capabilities of a bee. Thats what we are moving to and we call it the epitome of the art of flight

    For Micro-UAVs yes. For manned aircraft, no.

    Ah, if only we could build an aircraft that would fly like that.

    What AV-8B Harrier II is somehow close to flying like a bee? Not even close. A bee's momentum is many times that of the Harrier. Russians have designed a more efficient YAK-41 and thats way back in 20th century.

    Big deal its a VTOL, u

    How not?

    Please explain how that is possible, since momentum is found by mass multiplied by velocity. I think you'll find that the momentum of a bee is negligible compared to that of a Harrier.

    I think you'll also find that the Harrier was also designed "way back in the 20 century" - and considerably before the Yak-141. And also you'll find that the "more efficient" Yak-141 turned out not be even sufficiently efficient to go into service and remained as prototypes only.

    why not make micro UAV macro UAVS.It is literally possible, the only problem is the math and cost involved o r what do you guys think

    The problem is the power supply: batteries can be small and light enough to power a micro-UAV but if you make the UAV larger then the power supply needs to be larger, and being larger is therefore heavier, in addition to being fitted into a heavier UAV. So you have to switch to a different source of power which requires the carriage of fuel = more weight.
    You run into rapidly diminishing returns based on the cube-square law.
    So it isn't literally possible. At least for the time being.

    Personally i like Joint Strike Fighter

    here is a video of it testing.

    http://video.google.com/videoplay?docid=-4742849525846050256#

    this jet is the true Allie universal jet.

    and should be the replacement for the Canadian Cf-18 hornet. why would our government invest money and reasearch into it's development if not.

    I am a little concerned with only a single jet engine though esp for use in the Canadian north.

    as for speed, we have reached our limit for manned air craft.

    The human body is at the limits for the amount of g-force it can take with out blacking out. we were at that point a while ago.
