Webb12 nov. 2001 · For this reason, the rudder is modeled as a mechanical spring using the following relation: (14-10) where T = torque produced at rudder's connecting axis by oncoming air k = spring constant (set equal to the maximum torque value, 0.2 Nm) θ 1 = rudder rotation angle θ 2 = rudder rotational reference angle WebbA device used for steering and manoeuvring a vessel. Higher aspect ratio reduces the astern torque considerably. If one ship passes close to another in overtaking it, the ships initially repel each other. This kind of a rudder can act as a reaction blade by deflecting propeller outflow using its total movable area.
