Ship turning radius

WebThe manoeuvrability decreases which, amongst other things, manifests itself in a substantial increase in the turning circle of the vessel or the required bend radius, e.g. on a river. The squat (a combination of a mean bodily sinkage plus a trimming effect) increases by a decreasing keel clearance which makes touching bottom more probable. WebThe missiles initially turn towards the target with a known turn radius. I have to calculate the point at which the turn takes the missile to heading at which it will turn to directly attack the target. Obviously if the target is at or near 45 degrees then there is no initial turn the missile just goes straight for the target.

Merchant ships usually turn in a circle having a diameter of about 3–4 times the length between perpendiculars (LBP). The larger the rudder, the smaller will be the Turning circle diameter(TCD). This manoeuvre is carried out with the ship at full speed and rudder helm set at 35°.

WebFor example, for a ship on a steady turn with a diameter of 5 ship lengths, or L/R=0.4, then from Equation (8.75), approximate β=9° and from Equation (8.76) approximate β R =19.8°. A typical flow-straightening angle is about 10° and a rudder with a set helm of 50° would therefore see an effective incidence of about 40°. WebWhen driving a car, a vehicle’s turning radius can affect its maneuverability and safety. It affects how much space it takes to turn a car. The greater the turning radius, the more space the car requires to turn. For example, a rectangular vehicle’s turning circle is equal to its diagonal length. Some boats can also turn this way, but the ...
