F-107A—VAID is the word

The North American F-107A lost in the competition where the Republic F-105 Thunderchief prevailed but its Variable-Area Inlet Duct (VAID) technology was utilized in two equally rakish subsequent North American designs—the A-5 Vigilante and XB-70 Valkyrie. Evolution of VAID technology made its way to Lockheed’s SR-71, as well.

J. Terry White has penned an excellent piece in his blog American Aerospace on the F-107A here and is well worth the read.

    Joe:
    I had forgotten about this one. The article you linked in your photos was an excellent summary of this excellent aircraft. Too bad North American didn’t make it in competition with the F105 and the later F-22 competitor the F-23. NAA made many great, notable aircraft ;

    ► F-86 Sabre‎ (14 P)
    ► North American P-51 Mustang‎ (1 C, 16 P, 1 F)
    ► X-15 program‎ (17 P)

      Thanks for the listing…it speaks for itself. NAA was one of the great ones, no doubt.

    Sometimes aircraft ‘lose out’ for aesthetic reasons. Sometimes, those in higher command just don’t like the look of a machine. In the case of the F-107A, this quite possibly true!

    As to the N.A. aircraft list….it has always been a puzzle to me why they didn’t stay with the proven Packard/Rolls-Royce Merlin engine for the F-82, rather than reverting to the Allison engine. I know that there would have been a licensing fee to pay R-R, but it would have been a far better aircraft in my opinion.

      Can you imagine what the P-38 could have done with Merlins? Outstanding with the turbocharged Allisons, but one has to wonder what the performance specs would have been if they stuck Merlins in it.

        What an airplane that would have been. And wasn’t it decided to not super or turbo charge the P-39’s engine? Another inexplicable design decision place upon a manufacturer.

      You have to admit, the F-107 would not have won any beauty contests. Hangar talk had it being a “pilot eater” if you had to eject with that huge intake behind the cockpit, but in fact it worked, and was one of the first that would blow the pilot right through the canopy without jettisoning it first.

      Speaking of the USAF and esthetics. Camouflage research shows the best color for disguising the shape of an airplane at night is a mottled baby blue to darker blue livery. The USAF did not want to paint their fancy stealth machines any powder blue, so they went with a more “manly” black. Ever notice what color Russian warplanes are painted?

        Yes. I agree completely. Blue cammies have one disappear into the night better than black ones–but black is the western fashion choice 😉

      The possibilities are varied. Politics? Economics? Personal bias?
