Most of the important technical aspects of the two prototype Concordes and of their Olympus 593 powerplants have been explored and the aeroplanes are flying regularly at Mach 2.0 over long distances. The current status of the powerplant performance, further performance development, the engine and intake control systems, the reheat and exhaust systems, engine/intake compatibility, bench and flight engine development programme, the environment and service experience, are reviewed. Convincing performance demonstrations have been made and active discussions with airlines are in hand regarding production versions of the aeroplane.
