    Nah, you need more than afterburners. The SR-71 had some very advanced nozzle inlets for its engines which allowed the plane to move and bounce the supersonic shockwave around in the engine inlet to generate extra compression and to keep the incoming air from just building up and flowing around the engine instead of through it. If you took a F22 and pushed it up to those speeds, it would flame out and stop working long before it got near the SR-71’s too speed.

    I wish I was an engineer, but I have read a few mechanical engineering books with chapters on gears, and it really is a bottomless pit.

    In the example, I recall seeing a method a ways back where 3 interlaced gears could rotate simultaneously. Two are linked traditionally, while one is a helical gear that slides though the teeth of the other two. It had a slick animation, wish I could find it.
