FIELD: test equipment.
SUBSTANCE: invention relates to test equipment, and more specifically to tests of precision opened structures of spacecraft. Device for weightlessness of precision opened structures of spacecraft comprises two-arm lever, on one end of which there fixed is object to be weightlessed, and on the other balancing weight. Double-arm lever is equipped with hinged device with horizontal and vertical axes of rotation. There is a sensor for determining unloading force and a metal band with tension units. Adjustment of balanced state of two-arm lever relative to point of intersection of horizontal and vertical axes of hinge device is provided with yokes with threaded pins, balancing weights. Presence of elements of optical control – reference signs, provides accurate determination of position in space of point of intersection of horizontal and vertical axes of hinged device of double-arm lever and point, which is center of plug for attachment of suspension.
EFFECT: higher accuracy.
