Thrusters

As you know, without going into the theory, mechanisms, known as thrusters (PU), in fact, are a form of active steering of the ship. Prostejov PU constructively is horizontal below the water line pipe with a drive and propeller, the direction of the driving force which is perpendicular to the direction of motion of the ship. Like many other marine devices, thrusters began to apply first sailors, and then the shipbuilders and shipowners in many kinds of sea and river transport, after a successful debut in the ship modeling sport, where they were first in the early 40-xx of the XX century, used as autopilot, which allows to deal with abnormal patterns of course. Their operating principle is simple: in the stern, the water part, the weather vane was installed, which, when the model was strictly on the wind, along ustanalivalsya longitudinal axis when the ship began to deflect airflow rushes along the blade surface is not the wind vane, and at an angle, causing it to razvorot.Eto, in turn, led to a reversal of the rudder of the vessel, the device t.k.eti connected through transmission. Such an autopilot, a simple and reliable as an excellent tool strong coffee, could not help but be interested boaters, uchastvovavshish sleepless in single races round the world, and in 1964 in his another circumnavigation his first used by F. Chichesterzo, and soon after him – and many other ship owners and shipyards around the world. Since then, PU accustomed to vessels of all types have undergone significant design metemarfozy, expanded their range of applications. .
