A large, positive δ3 angle offers some advantages over the usual zero δ3 teeter rotor; such as reduced flapping angles, reduced in-plane excitations, and reduced teeter restraint impact loading. This paper discusses these advantages and presents results from theoretical analyses, computer simulations, and atmospheric tests on the University of Texas at El Paso (UTEP) test-bed turbine. Results from these simulations and tests indicate stable and controlled teeter response at high yaw angles and yaw rates at wind speeds up to 30 m/s. Results of atmospheric tests also show reasonable correlation with the code TEETER, but some discrepancies with past and present versions of the code YAWDYN.
