Abstract

Mass-geometry characteristics at a final stage of the aggregate assembly of flying vehicles are experimentally verified with special control stands, taking into account design features of the vehicles. When defining the center-mass position today weight-based measurement stands are usually used, whereas inertia moments are being defined with use of physical or torsion pendulumbased stands. Measurement process requires here multiple displacement of the item under control through operated
stands. Poor accuracy and low performance of both types stand equipment hinders in enhancement of control over mass-geometry characteristics, actualizing upgrading of both design of the stand equipment and methodical support of the above characteristics measurement to reduce the time of the experiments and to raise exactness in defining of the same characteristics. The work discusses design of stands based on swinging stage mode enabling establishing of both mass center coordinates and inertia moments after the device was put on the measuring unit of the stand, and on the mode of dynamic balancing for precision defining of mass-inertia asymmetry of devices. Specifications of the stands are adduced.
