Modification of Model Rotor Rig for Testing of High-Speed Advanced Compound Rotorcraft in the Glenn L. Martin Wind Tunnel
Abstract
The objective is to generate a comprehensive set of measurements of the blade surface pressures,pitch link loads, hub loads, blade"" deflections, fixed-wing(s) loads, propeller torque, rotor wakesand performance of high-speed compound-rotor systems consisting of"" a main-rotor, fixedwing(s) and a propeller for a range of thrust and lift sharing. These data are crucial to validateadvanced CFD"/CSD tools as well as gain improved understanding of the fundamental physics inhigh advance ratio flight conditions. A variety of M"ach-scale compound configurations will betested on our hover stand and in the Glenn L. Martin (GLM) wind tunnel, covering a range o"fflight conditions including full-disk retreating-side reversal (~ ~ 2). Many of these activities arealready in progress at Maryla"nd, but we are experiencing some deficiencies in data acquisitionand processing due to imprecise instrumentation.
