It does not refer to an electric motor in a rotating pod. The device is different from the Voith-Schneider marine propulsion system (also mechanically linked), which can also quickly change the direction of thrust, as the Z-drive uses a shrouded conventional screw that pivots or rotates the propeller, unlike the variable-geometry blades of the ...
Advantages of the sterndrive system versus inboards include simpler engineering for boatbuilders, eliminating the need for them to design propshaft and rudder systems; ease of trailering and shallow water maneuvering (with the drive trimmed up); also, a significant space savings with the engine mounted all the way aft, freeing up the boat's ...
There are two major variants, based on the location of the motor: [citation needed] Mechanical transmission, which connects a motor inside the ship to the outboard unit by gearing. The motor may be diesel or diesel-electric. Depending on the shaft arrangement, mechanical azimuth thrusters are divided into L-drive and Z-drive. An L-drive ...
Pilots anticipate the need for rudder when changing engine power or pitch angle (angle of attack), and compensate by applying left or right rudder as required. Tail-wheel aircraft exhibit more P-factor during the ground-roll than aircraft with tricycle landing gear, because of the greater angle of the propeller disc to the vertical. P-factor is ...
In the kayak, the amount of exposure of the skeg to the water, and also its effect on the position of the boat's centre of lateral resistance (CLR), is freely adjustable by the crew. The adjustment varies the degree to which the wind affects the boat – that is, the amount of lateral movement the wind can cause by impacting the upper parts of ...
An azimuth thruster is a configuration of ship propellers placed in pods that can be rotated on the horizontal plane, making a rudder unnecessary. These give ships better maneuverability than a fixed propeller and rudder system.
Donald Trump mocked Canadian Prime Minister Justin Trudeau over his top minister’s surprise resignation — after the pair clashed on how to handle the president-elect’s looming tariffs.
Direct drive, in which an actuator is attached to the steering quadrant, at the top of the rudder stock inside the boat. This is the least intrusive method of installation. Wheel mounting, in which a motor is mounted near the steering wheel, and can be engaged with it when in use. This typically involves either a belt drive or a toothed gear ...
