Wind Tunnel Performance Tests of a Full-Scale Proprotor on the Tiltrotor Test Rig Addendum: Numerical Data

The Tiltrotor Test Rig (TTR) is a large-scale proprotor test system for the National Full-Scale Aerodynamics Complex (NFAC). The first wind-tunnel entry was completed in November 2018. The rotor tested was the Bell Model 699, an AW609 rotor modified specifically for wind-tunnel testing. The TTR and rotor were tested up to 273 knots in axial flow, which is the highest airspeed ever achieved by a full-scale proprotor in any wind tunnel. Extensive conversion-mode and hover/climb data were also acquired. Previous reports presented results for all test configurations, including numerical data for hover/climb conditions. The axial-flow and conversion-mode numerical data used for those reports are presented herein.
