Research teams at NASA's Glenn Research Center outlined a suite of software codes developed to predict and analyze aircraft engine noise. Copies of the software can be requested from NASA's Software Catalog.
Jet and Fan Noise Prediction Codes
Research teams at NASA's Glenn Research Center develop theory and software to predict the noise from aircraft engines, helping engineers design and analyze improved propulsion systems. According to NASA, codes like JeNo predict jet noise using Lilley's Acoustic Analogy and mean flow solutions from a Reynolds-Averaged Navier-Stokes code.
Other tools, such as MGBK, have been used to analyze the noise reduction benefits of chevrons on turbofan nozzles. Programs like V072 and TFaNS assist with rotor and stator interaction tone noise predictions during early design stages.
Advanced Flow and Rotor Analysis Tools
NASA outlined additional software including Linflux, which studies realistic three-dimensional flows and blade geometries, and BFANS, which calculates broadband noise from turbulence impinging on blade leading edges.
Tools like WOBBLE compute propeller noise associated with varying inflow angles, while ADPAC solves tightly coupled internal and external flows through future-concept short-duct turbofan engines.
