FIELD: test equipment.
SUBSTANCE: invention relates to test equipment, and more specifically to ground-based experimental development for weighlessing of disclosed structures of spacecraft. Rotary device with a block and tackle system for weighlessing of opened structures of a spacecraft comprises a straight-line guide with a carriage, on which rollers and pulleys are installed with flexible element and movable unit, connecting element to center of mass of link of tested mechanism and counterweight. Device is equipped with a shaft, fasteners to a stationary power structure, a beam with a bracket for sealing of a flexible element, a profile structure and two length-adjustable tie-rods. Stretch bars are connected with rectilinear guide bracket with roller fixed on it. Flexible element passes through the roller.
EFFECT: enabling expansion of functional capabilities.
