B63H MARINE PROPULSION OR STEERING (propulsion of air-cushion vehicles B60V1/14; specially adapted for submarines, other than nuclear propulsion, B63G; specially adapted for torpedoes F42B19/00)
Introduced: September 1968
Description
B63H encompasses propulsion and steering systems for waterborne vessels, including propellers, screws, jets, paddle wheels, and rudders. The class covers the mechanical and hydrodynamic design of marine propulsion devices, steering mechanisms, and associated control systems. This includes arrangements for mounting propulsion units, thrust transmission, and directional control of ships and other water-based craft. Adjacent classes address hull design (B63B), vessel-specific systems (B63C), and related marine equipment, while B63H focuses specifically on the propulsion and steering functionalities themselves.
