The analysis of rigid hub, three-bladed horizontal-axis,
axisymmetric wind turbines in yaw is made using a linearized,
four-degree-of-freedom model. The linearized equations of motion of
rotor and nacelle are developed using quasi-steady blade element
theory and Lagrange's equations.
The yaw behavior of the system is studied from coefficients of
the...
Expanding groundfish production on the West Coast and in the
United States in total, over the past decade, has increased
competition in the groundfish market. During the same period,
regulations have evolved to control production in the groundfish
industry for the purpose of conserving the resource. Other
regulations exist to...
