PROPULSION-STEERING COMPLEX Russian patent published in 2009 - IPC B63H5/125 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to outboard propulsion-steering complexes of watercrafts, mainly hydroplanes and amphibians. Proposed complex consists of power drive and full-rotary column with water propeller arranged in guide nozzle to move out, into transport position, and in. Full-rotary pivot-type column comprises upper angular reduction gear and lower angular reduction gear. Propulsion-steering complex is provided with mechanism transmitting rotation from power drive to water propeller and consisting of driven shaft and toothed coupling. Aforesaid mechanism consists of two parts, i.e. drive and driven. Mechanism drive part accommodates toothed coupling drive part, while driven part of the mechanism accommodates toothed coupling driven part. Propulsion-steering is furnished with fairing arranged on watercraft stern.

EFFECT: improved performances.
