propulsors
Devices producing thrust
Propulsors are devices that generate thrust to move something forward—typically a vessel through water or an aircraft through air.
The term covers propellers, jet engines, water jets, and similar mechanisms.
In marine contexts, propulsors often refers specifically to specialized thruster systems: The submarine's propulsors were designed for quiet operation.
The singular propulsor appears in technical specifications.
