The J-58 made simple(r)

I got a copy of the SR-71 Pilot’s Manual as soon as it became available in the early 1990s. It’s a throwback to the days of slide rules and handmade graphics and utterly fascinating. There is a lot of material on the Pratt and Whitney J-58 engine and the Lockheed inlets that powered the Blackbird beyond Mach 3 yet I have never been able to fully understand why and how that system did what it did. Thankfully, Blackbird enthusiast Tech Adams explains it all in his delightful video – The Mighty J58 – The SR-71’s Secret Powerhouse.
