    I would think that direct, conclusive proof would have been offered if true (esp if done 10x times)

    Would be quite the “look what we’ve done” story to be boasted world-wide.

    My opinion however, not fact.

    “……20 percent negative stability was finally
    achieved within the specified limits of Mach 1.3 and 650 knots by the time the trials were successfully concluded……..”

    That is quite remarkable, esp for the flight regime. Amazing what can be done with some fast computers (for the era) and good software. The flight test program must have been a very much controlled crawl/walk/run approach. Using a fairly ‘docile’ T-33 is one thing… an F-104 quite another I would think….

    Pretty neat!!

    Nice photos, Kabuki. I think the one featuring the GBU-24B is especially neat.

    The fourth post includes two photos showing a white- and blue-colored rocket device – what type is it?

    Genie rocket (nuclear armed) on the F-89

    can it also be used to make the plane unstable? (offcourse not physically )

    As Bill G. would say, anything’s possible with software 🙂

    Calspan in particular has modified both a T-33 and Lear 25 to do something similar to what you are asking. Take a ‘normal’ aircraft and change its handling characteristics via software

    They had a B-47 laying around at China Lake back in the late 80s. Wonder if it is still there. Got to take a look inside. Quite the cockpit arrangement as you say. As was stated, the third seat was arranged below the other two seats. Not much of a view to the outside world as I recall…

    Didn’t spend much time, but all I could come up with was this picture of KE-3A

    http://www.rob.clubkawasaki.com/jas4684.jpg

    and vanilla E-3A

    Interesting that these guys also refer to an RE-3B

    Here are some S/Ns

    Can’t vouch for the info, but there may be something useful (I do note his tail numbers match the pictures, BUT the id is listed RE-3A vice E-3A??)…

    In that general area, probably yes, but more specifically I’d guess it was just north of Nellis with the picture looking to the East/Southeast…

    Just a guess

    Yes…. I think another F-15. The one the video is taken from is probably a ‘safety chase’ for the live missile fire event.

    The guy holding the camera must have gotten quite a workout. Camera gets pretty heavy under 5-6 Gs..

    bahh ugliest plane, along with Mig-21 and others

    You’ve just made yourself an issue with PII… :rolleyes:

    But that’s the main reason why the Phantom is so adored!!

    one thing i dont get about HUDs; IF you have HMS then why do u need a HUD?????

    It was the case (maybe not anymore???) that the HMS was not accurate enough for air-to-ground visual weapons delivery. HMS was close but because it can move around on the head (a little) the kinds of accuracy needed for EXACT aimpoint could not be provided.

    Air-to-Air weapons are a different story (more ‘slop’ as the seeker has FOVs in degrees vice pipper for ground attack is in the milliradian category; usually around one tenth of one degree).

    One of HMS biggest values is off-boresight target acquisition (both air to air and air to ground). Don’t have to point the aircraft at the target to get HUD cueing for the pilot.

    what about Harpoon? Is it wired for that?

    FlugRevue seems to think so…

    http://www.flug-revue.rotor.com/FRTypen/FRF-35.htm

    Couldn’t find anything ‘official’ though

    I would suppose that since the JSF is capable of carrying other ‘smart’ weapons (with 1760 interface), that it could interface with Harpoon as well.

    Determining what is/is not carried will boil down priorities as flight testing/simulation work will be limited. The initial ‘certified’ weapons list will be fought over with the various constituents (US services and other users/buyers). Weapons certification will be conducted over many years and probably will hardly ever be complete as new ordnance is developed and unanticipated configurations are identified.

    And then you get politicians involved….

    The program gets stretched WAY out, inefficiencies in production build, vendors drop out of the program requiring a search for new vendors (read more cost), overall buy goes down because program costs are up (so the per unit cost goes even higher). Politicians demand fewer aircraft per year to deal with costs, schedule gets stretched out even more….

    Yikes, it’s amazing anything ever gets fielded

    Here’s a good site I came across with the following info…

    “….The term “holographic HUD” brings to mind something out of Star Trek or Star Wars, perhaps a little 3D image of a gremlin standing on the aircraft’s nose alerting the pilot to potential threats or targets by making obscene gestures. Sadly, such is not the case. The reality is much more mundane. A holographic HUD simply uses a holographic optical element or HOE as the combiner. This is a specialized diffraction grating that can both combine and collimate. HOEs can be made very wavelength specific to allow the maximum amount of light from the forward field of view to pass through to the pilot. A holographic HUD can deliver a larger field of view for a given weight than can a HUD based solely on lenses and/or mirrors. …”

    I guess the term “mirror” is a relative one. I suppose if it reflects light it can be considered a mirror (so I stand corrected on my previous comment)!!!
