Electric Drive Architectures for Linear-Stroke Marine Propulsion
Rotary Conversion vs. Direct Linear Electromagnetic Actuation
From the essay
The concept of Phase-Structured Marine Propulsion, developed in the companion paper, departs from one of the deepest assumptions in marine engineering: that propulsion should be understood primarily as continuous rotational forcing applied to water through a propeller. In its place, the earlier paper proposed a different interpretive framework, one in which propulsion is viewed as a structured interaction between machine motion and the surrounding fluid across multiple operating phases. Under this view, thrust generation is not a single homogeneous event.
