How a Subsonic Jet Engine Core Can Power a Supersonic Aircraft & Why Concorde’s engines did not run supersonically, even though the aircraft did
Concorde cruised at Mach 2, yet the airflow inside its engines remained subsonic. The secret was its remarkable intake system, which used controlled shock waves to slow and compress supersonic air before it reached the compressor. This article explains how the Olympus 593 engine, intake ramps, and nozzle worked together to make sustained supersonic passenger flight possible.
