You can’t argue with the fact that the SR-71 is the most intricate plane ever developed. Sure, we now have the F-22 and F-35 which are fifth-generation planes full of software, gadgets and goodies, but let’s keep one thing in mind. The SR-71, as far as we know, was introduced in 1966.
This comes way before all the software and hardware technology we have now. This plane was developed using genius minds, paper and slide rules.
The Pratt & Whitney J58s were only used on the A-12 and SR-71 jets and their variants.
Think about that for a second. This plane still holds the world record for the fastest air-breathing manned aircraft. It is without a lack of better words, the greatest achievement in aviation engineering’s history.
But how did they achieve that?
Well, the answers are many. From the materials used to its intricate shape and size, every little aspect of this plane was meticulously drafted, built and tested. All that wouldn’t be necessary however, if it wasn’t for the two Pratt & Whitney J58 turbojet engines that powered it.
This is what this video is about. This engine was the secret behind everything this plane could do and you’ll find out how it works (with simple explanations.)
