    It is impossible to look at this image and not make "THOOM THOOM THOOM" noises.

    Anyone else notice the two pulses (where thrust went to maximum perhaps)? This engine would make quite a handy morse code device...

    Some kind of techno-Eldrich death machine.

    that's freaking AWESOME.

      The pretty flower-like petals around the exhaust stage are for thrust vectoring.

        Actually, no. Pretty much all jet engines for supersonic aircraft have those. They're not for vectoring, they allow the area of the nozzle to be adjusted to optimize the thrust for given throttle levels and atmospheric pressure at different speeds and altitudes.

        While a version of the F135 does vector (for the F-35B), it is not the petals but a 'lobster tail' segment upstream of the petals that does the vectoring.

        Edit: Oh, and to clarify, yes, there are some engines, notably Russian, which do use the nozzle petals to do some thrust vectoring, but none in the West at this time. The F-22 has vectoring, but uses a '2-D' nozzle with a square aperture, not the round petal design.

    Great band name, there.

    Sweet. My (old) boss worked on the team that tested the F119 engine that this is based on.

    I love the little fire extinguisher in the bottom left corner of the picture!

    I'll take two, with walnut grips.

    I'm pretty sure that's actually a Pratt & Whitney promotional image. I'm a contractor for them, and see that image all the time (on their website, on posters in the hall, etc.)
