    SERDP09 MDOE chevron nozzle noise database

    Metadata Updated: February 22, 2025

    A series of nozzle chevrons were designed to create a parametric family with varying length, penetration and width, with the objective of demonstrating noise reduction for supersonic nozzles. Eight sets of chevrons were fabricated and tested on the High-Flow Jet Exit Rig in the Aero-Acoustic Propulsion Lab at the NASA Glenn Research Center in 2009. Details of the test are given in the paper "An MDOE Investigation of Chevrons for Supersonic Jet Noise Reduction" by Henderson and Bridges (DOI: 10.2514/6.2010-3926). This data repository contains a test requirements document with configuration and flow definitions, a spreadsheet with measured jet flow conditions from the test, chevron geometry files in CAD format, and a set of files containing spectral directivity measurements of the acoustic far-field at the ~350 test points. Details about the data files are contained in a README document.
