SHIPBOARD PROPULSION AND STEERING COMPLEX Russian patent published in 2000 - IPC

FIELD: shipbuilding; manufacture of propulsion and steering complexes. SUBSTANCE: proposed complex is intended for high-speed boats. Complex includes water-jet propeller, nozzle with astern running shutter secured on it and control system. Nozzle is swivel relative to vertical axis. Control system includes control lever which is kinematically linked with axles located longitudinal and transversal relative to ship's CL and linked with nozzle turn actuating mechanism and astern running shutter actuating mechanism, as well as with engine control mechanism. Engine control mechanism is made in such way that engine speed is increased at shifting the control lever to AHEAD and ASTERN positions from neutral. Axes of turn of nozzle and shutter may be mutually perpendicular in projection of vertical transversal plane. EFFECT: simplified construction of complex; enhanced efficiency of ship handling. 2 cl, 1 dwg
