Advanced Olympus for Next Generation Supersonic Transport Aircraft

The paper summarises the background studies which have led to the proposal for an advanced Olympus engine, with mechanical noise suppression, to power the next generation supersonic transport aircraft. The recent international collaborative test programme on real engine scale ejector suppressors is described and reference is made to other Rolls-Royce experimental work at model scale. The envisaged changes to the design of the in-service Concorde engine are outlined and some installation aspects are discussed. It is emphasised that detailed refinement of the engine cycle must depend on the result of aircraft/engine integration and optimisation studies.
