Define directional stability
Webdirectional stability of ships. However, most ships with high block coefficient are inherently dynamically unstable. Ships having moderate or small amount of directional instability could be handled quite safely, but ships having large amount of directional instability are difficult to handle and may pose danger to sea traffic. WebThe motion is a rapid pitching of the aircraft about the center of gravity, essentially an angle-of-attack variation. The time to damp the amplitude to one-half of its value is …

WebYaw (rotation) A yaw rotation is a movement around the yaw axis of a rigid body that changes the direction it is pointing, to the left or right of its direction of motion. The yaw rate or yaw velocity of a car, aircraft, projectile or other rigid body is the angular velocity of this rotation, or rate of change of the heading angle when the ...

The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability).
