We describe a parametric experimental study of noise reduction via de ection of the secondary stream in dual-stream jets. The jets simulated the exhaust of turbofan engines with bypass ratios 4.5 and 6.0. The secondary (bypass) stream was de ected downward by means of vanes installed inside the bypass duct. Variables included the number of vanes, vane angle of attack, azimuthal placement, and a...

Data-driven modeling is an imperative tool in various industrial applications, including many applications the sectors of aeronautics and commercial aviation. These models are charge providing key insights, such as which parameters important on a specific measured outcome or parameter values we should expect to observe given set input parameters. At same time, however, these rely heavily assump...
