Algorithm for yaw stabilization of a towed vessel
Vestnik of Astrakhan State Technical University. Series: Marine engineering and technologiesTowing is one of the most difficult and risky tasks of navigation, since in this case two or more vessels are involved simultaneously. A minimal number of towing-related accidents have been recorded, but they still occur, and the issue remains of improving the safety of such operations.

The effect of delta 3 on a yawing HAWT blade and on yaw dynamics [PDF]
, 1982 A single degree of freedom aeroelastic computer model, WMSTAB3, was employed to perform a parametric analysis of HAWT blade behavior during yaw maneuvers. Over 1,000 different combinations of delta sub 3 and normal frequency were analyzed.
