First time I'v seen a good picture of a pulse jet engine. Wonder if they are synchronized?

SR-71 J58 motors are ram jets; what you see are the afterburner plumes.

actually, the J58 was a classic axial flow turbojet, but the inlet temperature to the turbine was limited at reaching about Mach 3, so at that speed, the majority of the thrust was from the afterburners. But you are correct, the exhaust plumes are being modulated by shock waves.

Yep. I should have stated turbo ram jet. Good discussion in layman’s terms here.

Dubbed "black magic," the J58 Turbo-Ramjet Engine pushed the SR-71 (as well as the A-12 and the YF-12) from 0 to Mach 3.2.
