Description

Class F03 encompasses machines and engines that convert energy from liquids, wind, springs, or weights into mechanical power or propulsive thrust, covering technologies not classified elsewhere in mechanical engineering. This includes hydraulic and pneumatic motors, wind turbines, water wheels, tide and wave energy converters, spring-based mechanisms, and gravitational force engines. The class also encompasses reactive propulsion systems and related equipment for generating or controlling mechanical motion through these non-traditional energy sources. Adjacent classes F01–F02 cover internal combustion engines and turbines respectively, making F03 the residual category for alternative and renewable energy conversion devices.
