Inside the engine that powers the SR-71. It's really not all that complicated, until it gets complicated.

I had a basic knowledge of how some of the systems work on that engine. Now, I understand (?) a bit more of the systems involved. Whew! It really isn't rocket science. It's turboramjet science. Which seems to be a lot more complicated. Thanks.

And they did all that with a slide rule, or rudimentary computers at best. That's what's truly amazing to me. That video does go pretty fast though. I need a little time to digest all of it.

"Inside the engine that powers the SR-71. It's really not all that complicated, until it gets complicated."

Well said. I was all on board until about 3:15, nodding my head as they zoomed the model out. Then I looked at the timeline and saw there was over two minutes remaining.

Oh.. there's more....

Then came the part about cowl bleed, shock traps, suck-in and tertiary doors. It all made sense, and was something I didn't know about cooling the thing. I also realized all the extra engineering required to make it able to fly as slow speeds.

Again, I was nodding my head in understandi... Then I saw there was a minute left.

Then came the two-way boundry layer center body bleed, exterior grills, spike slits, more talk about the shockwave (which I thought they already had figured out) and then I....

Oh no....

I like the Buick-engined starter carts these monsters used!

And to think this was all done with slide rules and, at best, rudimentary computers.

Someone smack McMike in the back of the head! he's gone cross eyed.

I just stumbled across this J58 video through another source... I was going to share it here on Oppo, but did a search first... Good thing... Not much Aerospace stuff gets past You or F86Sabre... ;-)

Did you see the accompanying video they did on the Blackbird ?
