English term or phrase:
Shaft Trailing, trailing mode
German translation:
Propellerfreilauf (ausgekuppelter Propeller)
English term
Shaft Trailing, trailing mode
ich hätte da mal eine Frage, bezüglich eines Projektes an dem ich momentan Arbeite.
Es geht um Schiffsbau - Antriebe bei Schiffen.
Im Ausgangstext (USA) steht folgendes:
Shaft Trailing
In trailing mode one propeller shaft is not activated and the propeller shall be driven by the water.
The operator shall have the possibility to select the shaft trailing mode when the ship is sailing at sufficient speed.
In trailing mode, the optimum pitch of the trailing propeller can be adjusted by the operator via the PCS and locally.
Before engagement of shaft trailing, the AKS shall check the following conditions:
Meine Frage nun:
Geht es bei der Thematik tatsächlich um den Betrieb im Schleppmodus oder um einen nicht aktiven Propeller?
z. B.
trailing mode = Schleppmodus ?
Shaft = Welle Trailing = Schleppen ?
Ich bin mir nicht ganz im Klaren, was genau „Shaft Trailing" zu bedeuten hat.
Wäre schön, wenn ihr mir da helfen könntet.
Schöne Grüße
Sascha

Trail shaft or Trail shaft mode.A engine operation mode in which a DDG(destroyer),based on GTM engines,can voyage on a high efficiency of burning fuel.In trail shaft mode the ship(DDG,destroyer) operates one main engine and associated shaft, while allowing the other shaft to spin free(one engine online and one shaft windmilling). In split plant mode, redundancy of the propulsion plant is increased with two GTMs online, one for each shaft. Finally, full power mode is the operational state when all four GTMs are online, with two powering each shaft.

When a ship is being towed, the propellers should be locked, unless it is permissible and advantageous to allow the shafts to trail with the movement of the ship......
Marine drive shafts. On a power-driven ship, the drive shaft, or propeller shaft, usually connects the transmission inside the vessel directly to the propeller, passing through a stuffing box or other seal at the point it exits the hull.
