COMBINED ROTATING BLADE PROPULSION UNIT FOR UNDERWATER VEHICLES Russian patent published in 2023 - IPC B63H1/10 

FIELD: shipbuilding.

SUBSTANCE: invention relates to propulsion units with a vertical axis and a transverse arrangement relative to the flow with a constant controlled orientation of the blades. The combined rotating blade propulsion unit for underwater vehicles with a vertical axis and a transverse arrangement relative to the flow contains a rotor, which is driven by a drive motor; a plurality of aerodynamic profile blades is attached to the rotor, rotating together with it around a vertical axis with a constant orientation controlled according to the optimal law. The propulsion unit is paired and consists of two identical rotating blade propulsion units – upper and lower. Variable pitch propellers are additionally located in the centre of the rotating blade propulsion units. The rotors of each propulsion unit are rotated by a drive motor through a differential gearbox, on the output shafts of which the rotor hubs are mounted, and the hubs, in turn, are mechanically connected to the rotor rims by means of radial spokes, which are the axes of rotation of the propeller blades. Additionally, control rings have been introduced, which are a ring with a groove in the form of concentric cylindrical surfaces, along the leading belts of which control elements - rollers of levers fixed on the axes of vertical vanes - roll freely. The control rings do not rotate, but can move independently of each other on a plane transverse to the axis of rotation in any direction relative to the centre of the rotating rotor due to additionally introduced transverse and longitudinal displacement servos.

EFFECT: expansion of the arsenal of technical means to increase the dynamic capabilities of underwater vehicles.
