Vertical Climb Testing of the Model 699 Proprotor on the Tiltrotor Test Rig Addendum: Numerical Data

The Tiltrotor Test Rig (TTR) is a NASA asset for testing full-scale proprotors. The first test campaign in the National Full-Scale Aerodynamics Facility (NFAC) concluded in November 2018. The wind-tunnel test included vertical climb conditions simulated by axial flow at low airspeeds. The rotor tested was the Bell Model 699, an AW609 rotor modified specifically for
wind-tunnel testing. The rotor was tested under a variety of NFAC configurations, some unprecedented and unique to vertical climb. Previous reports presented results for all test configurations applicable to vertical climb, and included comparisons with earlier tests of a similar rotor, the 0.656-scale Joint Vertical Experimental (JVX) rotor. The numerical data used in those reports for both rotors are presented herein.
