Pressure-Sensitive Paint Data on the Facility Aerodynamics Validation and Research (FAVOR) Model at AEDC
Abstract
Arnold Engineering Development Center (AEDC) recently acquired the Facility Aerodynamics Validation and Operations Research (FAVOR) model for use as a standard check model for Propulsion Wind Tunnel (PWT) 16T. The test article is a 5% scale model of the F-111 with new wings having a NACA 64-210 profile, a fixed sweep angle of 35 deg, and a span of 48 in. The plan is to periodically install the model and test across the facility capabilities to validate that tunnel operational characteristics have not changed. The first test of this model was recently completed as the baseline for future tests. While the internal balance and installed pressure taps were the primary source of data acquired, several other types of on- and off-body data were acquired. These included pressure-sensitive paint (PSP), background oriented schlieren (BOS), laser vapor screen, and planar doppler velocimetry (PDV). Pressure-sensitive paint data were acquired for demonstration of the techniques' capability to measure surface pressure and determine total vehicle loads and for use in computational fluid dynamics (CFD) validation. The PSP data were compared to and validated by conventional pressure data measured on the model and with total vehicle loads measured by the internal balance. This report documents the results from the PSP and presents the data comparisons.
