Get out your skinny ties and checkered pants, because it is the 1960's. Bonus points if you have a round faced oscilloscope.
This is vintage NASA/Lockheed video of the YF-12. Some bits of this video were things I was unaware of. For instance, they built a stainless steel
oven the shape of the YF-12 to heat the plane for testing. The fuel was used as a heat sink. This is done in some modern aircraft, but I don't know
if the Blackbirds were the first to do this.
Either the F-22 or F-35 has it's bingo limit set by the need for heat sinking rather than just running out of fuel.
Excellent find Gariac, I had no idea about that NASA operated one of the YF-12's wired like a pinball machine to develop the comprehensive high mach
analytic tools used by the modern aerospace industry.
That is a really neat variation of the A-12 planform. The folding ventral fin looks similar to the XF8U-3, I wonder if the concepts developed
separately or if there was some sharing of data between the Chance Vought and Lockheed?
Though the author thinks this film is circa 1970, I don't think they XB-70 would have been included in the film since the fatal crash was in 1966.
Just a guess on my part.
