    According to gr00mi, fourth one will fly soon.

    They must have fixed the structural problems then.
    But surely the static test object and the ground test object should have been undergoing uninterrupted tests, right?:confused:

    talks of economic superiority are moot. In the end China will not be like the US because China’s rise comes at a time of peak oil threat.. once we hit that peak, global manufacturing becomes expensive and China’s function as the world’s sweat shop will be gone. Unlike Russia, China has high energy insecurity, worse than the US. It will be likely China becomes more dependent on Central Asian and Russian energy imports.. the problem is will Russia deliver? they’ve been unreliable suppliers in the past, can charge a lot, and many Russians are upset that … snip

    Yeah, but China is setting up shop all over Africa. They may get some oil and other items from Africa. They could go the way of Brazil with their ethanol and ease the demand for fuel. By that time IBM will be ready with their aerobic fuel cell which China can replicate flawlessly. :p
    On the other hand Russia is not under much threat. They have lots of Land, Resources, Oil, natural gas, Hydro potentials, and the global warming is making lots of land accessible to them.

    But they better have a whole lot of nukes pointed everywhere. Siberia looks tempting. Plus they need to fend off Norway, Finland, Canada etc… from ignoring their claims in the Arctic.:D

    The Scandinavian countries might be able to put a fiercer resistance than Canada though πŸ˜€

    If true, the only time the PD 14 will be used is for delivery to US sanctioned countries and in Military aircrafts.
    But then again, PD 14 is supposed to be competing with LEAP-X and PW1000G series on both efficiency and operational costs.

    Page 21.
    Did the designers compromised efficiency to design an engine usable for both Military and Civilian aircrafts.
    Bypass ratio of 7.2 and compression ratio of 46 for the PD14M

    are you saying F-35’s bump intakes are equivalent to MiG-21’s air intakes? :rolleyes:

    Of course not, but splitting them in half, file off the conical tip and then you have the semi-spheroidal bump. Then you rivet it to the sides of the aircraft.

    ah yes an AESA. can it fit into a MiG-21? upgrade of avionics is much easier than upgrading the airframe. Thunder’s airframe is at the moment the newest and most advanced in the world, isn’t it? 😎

    if you cut the mig 21 intake in two halves you get two DSI inlets which you can then rivet to the sides of the airframe ;). Mig 21s are dime a dozen down by the boneyard, that’s where they got those DSI intakes. If not DSI then use them as Mirage intakes.

    Not really, I think those must be MiG 15 pilots. :diablo::diablo:

    The Lightning is in fact, the British Su-9, Su-11.;)

    πŸ˜€
    English Electric Lightning looks better and could super cruise ;), and with an astonishing rate of climb. The Fishpot, :D, looks too primitive actually…

    we’ve never seen the US use two JF-17’s to power anything, or Russia making stealthy JF-17 like cruise missiles :diablo:

    But you forgot JF17 have two DSI intakes.
    1 DSI intake > 1 variable shock cone

    so JF17 with two DSI intakes > 2 variable shock cones

    In short JF 17 > SR 71.;)

    Such a small aperture, is it for fire control or terrain mapping/avoidance?

    Fadal CNC machines from the US of A:eek: Isn’t Globalization great?:diablo:
    But then again RD-180 were also used in the US space program.

    Interesting things going on in Rostvertol Plant

    Rostvertol Plant

    Mi 26 is huge inside. Nice cockpit too.:)

    I am not saying all VW tech is …

    I know very well how things are … Lets just say I am in the thick of all this action πŸ™‚ .
    Lets keep it aside, not related to this thread.

    F-22 of the world are not design in wolfsburg. they are more akin to Eurofighter. More mass produced and cheaper to maintain.
    F-22 will be more like Buggati Veryon or Ferrari Enzo.

    Russia can make hand made cars with similar design and performance but with British racing engine.

    Russian supercar Marussia challenges Ferrari and Lamborghini

    The current king of the Hill the Bugatti Veyron is designed by Hartmut Warkuss and approved by Ferdinand Karl PiΓ«ch himself. The car itself was tested in Ehra Lessien in Wolfsburg. The development was paid for and commisioned by Wolfsburg. Period.
    And before someone comes again and say they will have a faster car in America a new Veyron is on the line as well.
    By the end of the year, VW group will comprise of Lamborghini, Bentley, Seat, Skoda, Porsche, Audi, Ducati, MAN, Scania, VW, Bugatti, and few other marques on his Highness Winterkorn’s command from Wolfsburg.
    Or you are still going to tell me most of VW tech is developed in China?:rolleyes:

    But that being said I still like the KamAZ which is the current champion in Dakar Rallies, Go Vladimir Chagin!! And of course who would not like the Vityaz DT30

    Sorry for going off topic.

    F-135, which is estienally a F119 with a much bigger external hulls, althrough can deliever a 190kN thrust, but it has a last generation by-pass ratio of 0.6.

    Bypass ratio is a design choice not last generation :rolleyes:
    The Bypass ratio is designed to be 0.6 not because of engineering problems but because the designers want the majority of thrust to come from the compressed air to improve fuel efficiency giving the aircraft longer range. The increase thrust is achieved through increased airflow and very high inlet temperature which is currently unique to F135 @ > 2250K.
    By this logic the LEAP-X is extremely last generation with bypass ratio of 10:1 :p
    Even China wanted the LEAP-X for the C919
    If you want 0 bypass ratio get a turbojet.

    Ws-15 and Al-41 are both around at same level of development.

    AL 41 is a variable bypass engine. It is already abandoned by the Russians.
