FIELD: aeronautical engineering. ^ SUBSTANCE: proposed combined actuator unit includes body, hydraulic system with pressure and return lines, two-chamber hydro-mechanical drives, multi-channel servo units with rigid connection of hydraulic motors, electro-hydraulic valves for cutting-in servo unit channels and devices for centering servo unit rods. Each drive is kinematically linked with outlet of member of one of multi-channel servo units. Provision is made for differential pistons engageable with stops mounted on servo unit rods forming working chambers together with body which are communicated on side of stops mounted on servo unit rods with pressure or return channel of one hydraulic system. ^ EFFECT: reduction of overall sizes and mass. ^ 1 dwg |
