Because of the heat caused by friction of incoming air at Mach 2 speeds, which could reach 250 degrees Fahrenheit, titanium was used to produce the compressor drums and blades, except for the last four high-pressure stages, which were made of a nickel alloy. #SSTFirstGeneration This tweet was posted on January 19, 2023.

The Olympus 593 was developed jointly by Rolls-Royce of England and SNECMA of France. The engine featured low- and high-pressure compressors, which comprised seven stages each and were driven by a single-stage turbine. #SSTFirstGeneration This tweet was posted on January 19, 2023.

The Concorde’s Rolls-Royce/SNECMA Olympus 593 engines were atypical for commercial airliners.
