FIELD: automation for power control systems; control actuators of controllable flying vehicles working on gaseous medium.
SUBSTANCE: proposed air dynamic package consists of two servo units assembled in rocker arm configuration and kinematically linked with control surfaces; they are provided with distributing devices each of which is additionally provided with second plunger electromagnet. Magnetic circuits of electromagnets are connected by means of common flange fitted with armature common for electromagnets. Armature side surface has two circular grooves which are engageable with holes in flange during operation of actuator. These holes are used for communication of working chambers of servo unit depending on position of armature with high-pressure or low-pressure chamber. Armature and flange form three-way two-position plunger-type air distributor practically excluding the load on plunger caused by pressure of air being distributed.
EFFECT: improved dynamic characteristics of control actuator.
