SUMMING MECHANISM FOR CONTROL SYSTEMS OF COMMON AND CYCLIC PITCH OF HELICOPTERS OF THREE-POINT CONTROL SYSTEM WITH INCLINED ARRANGEMENT OF HYDRAULIC ACTUATORS Russian patent published in 2016 - IPC B64C27/64 

FIELD: aviation.

SUBSTANCE: invention relates to aviation, in particular to control systems of helicopters. Summing mechanism for control systems of common and cyclic pitch helicopters three-point control circuit with inclined arrangement of hydraulic drive comprises a system of input rockers, slider, movable and fixed brackets, fixed frame. Input pumping units are connected with handles cyclic pitch over “roll” and “pitch”. Slide is connected with common pitch control handle. Movable bracket secured on slide, can turn in plane perpendicular to input rockers, and move along guide fixed frame. Movable bracket is connected through a system of links with system output rockers to control hydraulic drives swash plate.

EFFECT: achieving implementation of advance angle control and compensation of inclined installation of hydraulic drives.
