    At this point obligatory sounds almost like some creationist nut. It takes special dedication to believe so strongly in a single number he found while dismissing and waving away every other piece of evidence that doesn’t fit into his view.

    everyone is posting normally except you.
    its fine since no names are being mentioned.

    A good number of threads you make are just trying to flame and bring out subjective opinions of others, seemingly to create arguments from that. You either lack maturity or you’re just trying to create tension and drama.

    This is nothing but a flame thread. Seriously how is this a productive topic at all? It’s just asking for mudslinging to happen.

    I don’t think obligatory has any solid grasp of fluid dynamics. Ideal shape is that of a water drop? What? Oh, and I’ve seen obligatory rave on and on about the Sear-Haack body without even fully understanding what it means. A true supersonic aircraft would not have it’s volume distribution symmetrical, the peak would actually be towards the rear because you calculate area through Mach-plane cuts. Sears-Haack volume is strictly for transsonic.

    An F-35’s area ruling isn’t the most ideal or have the greatest fineness ratio, but the question is whether it’s good enough for its intended role and provide reasonably good air combat maneuvering capabilities. Some of this eyeball conclusions is laughable to say the least.

    Of course, obligatory is also fond of repeatedly citing a “NASA study” (it’s actually a contract paper done for Boeing for their JAST configuration study) to show that the F-35 is “moderate observable” based on a preliminary configuration chart that doesn’t even detail RCS ranges for its classifications, and then concludes that GaN can then “nullify” it. And then he gets into nonsense like this.

    i think that new clever material spell the end of the troubled canted vertical tail layout

    And here’s a hint why that’s a load of crap and why shape is still the most important aspect of LO.

    Enjoy your gain of 20+ dBsm. :highly_amused:

    I’m sorry but when someone shows so much technical ignorance it’s hard to give him much credence. If he wants credibility, he should first read some books on fluid mechanics and electromagnetic theory.

    Mig 25 copy.

    Either your a troll or you are phenomenally stupid.

    Can mods do something about these nationalist posters? They don’t understand aviation and their “contribution” is worse than useless.

    Did JSR just say the Su-27 is less draggy than F-15? Then again I wasn’t expecting anything intelligent out of him.

    T-50 – 9.47 m2
    F-35 – 8.12 m2

    I think your T-50 drawing doesn’t show the main landing gear fairing. There should be a noticeable bump next to the inlets.

    Can Byoin, KGB, and Starfish Prime get in their own thread so we don’t need to deal with this retarded rubbish here (or in the PAK FA thread too). I’m tired of seeing China-bot, Russia-stronk, and Murica-great getting their stupidity everywhere.

    Yeah, wow. That’s frustrating. 😀

    It’s amazing that even considering the total mess of a patch job that the T-50-5R is, it’s still incredibly beautiful.

    Goodness, I can’t wait to see some similar in-flight footage of the T-50-6. Just imagine.

    *drools*

    Beauty. Still don’t know about that camo though, I would really like to see the T-50 in RuAF blue camo. Though it might very well be dull grey after all the RAM gets applied.

    The allowable “G” raising to 9 in 3i will give the F-35 an even more favorable instantaneous G turn comparison. One of its current strengths. Easing up CLAW restrictions should give the F-35 an even more pronounced pitch and yaw advantage. The full envelope is not going to make the sustained turn any better than it’s current average. This should be no surprise, the sustained turn performance is unexceptional, evidenced by the relatively low comparision score in the 9k perch bfm set up.

    I was under the impression that the inlet was currently the limiting factor for F135 thrust. I seem to recall P&W saying that the inlets would need modification to increase thrust. Do you recall where you read the inlets had sufficient flow?

    So I found this bit about increasing engine power for the F-35.

    http://www.airforcemag.com/DRArchive/Pages/2016/July%202016/July%2012%202016/Engine-Up-the-F-35.aspx​

    “Farnborough, UK—Last week’s matching $1 billion contracts to Pratt & Whitney and General Electric for the Advanced Engine Technology Program could produce a powerplant delivering 20 percent better fuel efficiency—hence much better range—for the F-35, Pratt’s Bennett Croswell, president of Pratt military engines, told Air Force Magazine Monday. The first block of the program could be designed by 2019 and in production in 2024, he said, delivering seven-10 percent better efficiency. Block 2 would follow five years later, with a likely 15-20 percent improvement over today’s F135 engine. However, Croswell said the F-35 would probably need to be modified to accept a new engine. The airframe is “basically wrapped around it,” and the fit is snug. While he said the intakes wouldn’t have to be altered, “the back end” would need to grow, “and if you do that, the exhaust nozzle” would probably have to be re-engineered as well. Croswell declined to speculate about whether the AETP program is meant to give GE—and competitive engine buys—another chance. The alternative F136 engine, developed by GE, was killed by Defense Secretary Robert Gates, who insisted it was unnecessary and wasteful.”

    I remember another older source stating that the F-35 inlet can accommodate greater thrust and flow than what the current F135 can do, but I can’t find it anymore.

    And I can’t believe people are still harping about the F-35’s infrared temperature based on the single engine’s thrust or turbine inlet temperature. Apparently it escapes some people that exhaust temperature depends on not only turbine inlet temperature, but also how much work is done by the turbine (to include electrical power generation), bypass ratio, and nozzle area ratio. Seriously, some people need to take a basic fluid mechanics class before mouthing off.

    But you are right.. no one would take the pig over a Raptor.. and likewise, no one would take it over a T-50 or J-20, either.. and that’s the whole point.. F-35 will be measured against these, not against F-18s and F-16s.

    What do we even know about the T-50 or J-20 that assures you that pilots will always take them over the F-35? Pure aerodynamics? At supersonic speeds sure, that’s very likely true. Yet what about items such as LO, avionics, and other items that also determine mission effectiveness? It seems like you’re always operating with the assumption that somehow the F-35’s LO attributes and avionics can always be bested somehow and in the end it’s all a matter of kinematics. Even though Russia can have unique and innovative solution, truth is Russia has traditionally lagged the west in avionics.l, and for them to somehow so suddenly reach parity of the F-35 in terms of avionics is assuming that the years of advantage in experience and investment can just be hand waved away. What do you even base this on?

    This doesn’t get into the fact that Russia is still buying more Su-30SM and China is getting more J-10s. Yet these planes likely stack up very poorly against the F-22, despite entering service well after the raptor, so should they be dismissed as well?

    Pretty sure the Mach 2 run was done with the GE engine. He said that he finally got the chance to fly the GE engine aircraft since he was primarily responsible for the P&W engine aircraft.
