Full scale tilt rotor hover performance
Web12). Also during this time period, hover tests of two full-scale tilt rotors (Refs. 13-14) and a 0.658-scale V-22 rotor (Ref. 15) were conducted. Narramore and Vermeland (Ref. 16) made one of the first attempts to address the delayed stall phenomenon using computational fluid dynamics (CFD) methods. Reference 16 performed calculations for WebThe objectives of this wind tunnel test were to (1) evaluate the capability of the 80x120 test section as a hover facility; (2) acquire forward flight rotor performance data for comparison with analytical results; (3) acquire S-76 forward flight rotor performance data in the 80x120 wind tunnel to compare with existing and future 40x80 data for ...
