Analysis of Adaptive Cycle Engine Noise for Civil Aviation
To improve fuel economy and reduce operating costs are one of the future developments of the air transport.From another part, it is continually called for higher speed to satisfy the global reach and make the world as a neighbor.An airworthiness problem of supersonic civil aircraft is the propulsion system noise.The ACE (adaptive cycle engine) noise is explored at the state of takeoff based on the description and analysis of aero engine noise and supersonic air transport.The conceptual scheme of ACE is shown and then the calculation method of each component is studied, including fan, combustor, turbine and nozzle.The total noise level (EPN dB) is calculated and the impact of components noise is analyzed.The research shows that the ACE noise is lower than the supersonic aircraft Concorde but higher than actual subsonic civil engine.The nozzle and fan should be paid an attention at the noise suppression and the airport location for supersonic aircraft could be a condition of market acceptation.
