Noise generated by TACAIR engines is an acute noise source and is a concern of the Department of the Navy. Historically, TACAIR engine performance requirements have increased without accompanying noise-reduction requirements, a trend which has resulted in increased noise challenges for the Navy. An understanding of the trades between performance and noise requires data acquired at relevant jet conditions using nozzle geometries of interest. The ability to effectively utilize the knowledge gained requires engineering design tools for noise-prediction validated with relevant acoustic datasets. The program will pursue the acquisition of acoustic data and development of engineering design noise-prediction tools/models for potential future tactical aircraft engine/nozzle architectures.The Office of Naval Research is seeking proposals that address both (1) the acquisition of noise data for multi-stream, hot, supersonic jets issuing from relevant, complex nozzle geometries and (2) the development and validation (using noise data acquired in (1)) of engineering design models/tools for noise prediction that could be used in future tactical aircraft system studies. The datasets and prediction models should address noise levels for relevant jet conditions at locations on the carrier deck and in the far-field where community noise is an issue. The nozzle geometries of interest are those that accommodate two-and three-stream engine/nozzle architectures including round co-annular and non-co-annular nozzles as well as non-round, vehicle-integrated nozzle configurations. The studies are not intended to include propulsion-airframe interactions. Relevant jet conditions include representative carrier-deck takeoff conditions and an appropriate range of engine cycle conditions expected for operations around airbases. The engineering design tools/models should be computationally efficient and intended for use in system trade studies where a large number of configurations must be evaluated.
