The Tiltrotor Test Rig (TTR) is a new 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 (true hover is not possible in the NFAC). 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. This paper presents results for all test configurations applicable to vertical climb, including assessments of data quality. Comparisons with earlier tests of a similar rotor, the 0.656-scale Joint Vertical Experimental (JVX) rotor, are included to provide additional insights into rotor and wind tunnel behavior.
