May 11, 2012 This paper evaluates various computational methods used to compute propeller performance, hydrodynamic side force and bending moment applied to an azimuth propulsor propeller shaft in oblique inflow. The two non-viscous models used are the BEM method and the blade element momentum theory BEMT. RANS calculations are used to compute the loads on the propeller and

An azimuth propeller device includes an azimuth pod, a POD propeller member provided with the azimuth pod, and a motor which drives the POD propeller member. The motor is provided inside the...
The electric motor inside Azipod is directly connected to the propeller and in this respect it is similar to the classical icebreaker shaftline, the only exception is that the shaftline is extremely short.
Dec 24, 2012 The first azimuth thrusters, where transmission is sent directly to a pod fitted beneath the hull containing the drive and propeller, were introduced into small craft in the 1950s. In essence this eliminates traditional shafts and gearboxes and, as the pod can rotate on its axis in any horizontal direction, it also eliminates the need for rudders.
Propeller speed is independent of engine speed ... ecause the electric motor is designed as an integral part of the thruster hub and attached directly to the propeller shaft, there are no gears boxes or gear reductions providing maximum system efficiency with lower noise and vibration ... The Azimuth Thruster ontrol System fulfills the ...
Apr 22, 2021 37.Azimuth-2 of 2-22.04.21 Twin Input Solution The second input flange is located at the opposite side from main input. As they share the same horizontal shaft the system is called Twin. Due to this, the rpm of main and auxiliary motor needs to be the
May 19, 2009 Azimuth Thruster is an arrangement in which the the propeller is placed in pods that can be rotated in any horizontal direction. This eradicates the use of a rudder. The stem of the thruster accommodates shafts that are connected to a motor located inside the ship. The Azimuth thrusters are divided into two types based on the position of the motor.
A Z-drive replaces the propeller, shaft, stern tube, marine gear, rudder and steering gear all with a single unit. Z-Drive azimuthing thrusters provide maximum thrust in any direction, independent of vessel speed, offering superior pinpoint maneuverability under all conditions.
The main distinguishing feature of the SRP is the combination of propulsion unit and azimuth steering. This makes a rudder superfluous and converts engine power into maximum thrust. The 360-degree steering of the rudder propeller means that the full propulsion power is available for manoeuvring.
of about 12 m, with the diesel-hydraulic drive system consists of two azimuth thrusters with power on each propeller shaft 80 kW. Due to the fact that the hydraulic drive enables a relatively easy adjustment of the direction and speed values assumed that the thrusters should be equipped with fixed pitch propeller, which
May 16, 2021 In an azimuth thruster unit, or Z-drive, the vertical shaft rotates to change the direction of thrust - to rotate the propeller about its horizontal axis. The rotating elements, however, are all connected via gears and shafts to the engine.
To properly choose a propeller we must first understand some of the basic nomenclature used to describe propeller geometry. Figure 1 is taken from Gilmer and Johnson, Introduction to Naval Architecture. Basic Nomenclature Hub The hub of a propeller is the solid center disk that mates with the propeller shaft and to which the blades are attached.
Apr 30, 2014 But in the Arctic, azimuth thrusters have been proven to be effective at moving large vessels through ice with greater ease and efficiency than shaft-driven propellers. Because the propeller blades are in front of the pod, where the electric-driven motor is located, they resemble the propellers on the nose of an aircraft and perform much in the ...
F x is the longitudinal force in the propeller shaft direction. F y is the transverse force perpendicular to the propeller shaft. Q is the propeller torque. M z is the steering or turning moment of the unit. All of these forces and moments are dependent upon the inflow incidence angle and of course the magnitude of the inflow velocity.
