FIELD: development of new equipment with rotating members for various branches of industry with upgraded technical and economic indices. SUBSTANCE: invention is intended for power turbine manufacture and for design of new types of aircraft. Shaft is connected to tachometer- frequency meter. Disc is put on shaft. Disc has at least one conduit connecting close to axis and peripheral zones of disc. Two identical springs are arranged inside conduit at some distance one from another. Each end of spring rests against proper slider. Body with freedom of movement is located inside conduit between internal sliders. External sliders are intercoupled by means of coupling gear for simultaneous movement to one or another side. Rotational speed of shaft is adjusted till critical value of circumferential velocity of center of mass of body on corresponding radius of its rotation is achieved which is determined with the aid of meter when equality of lengths of both springs is obtained. EFFECT: widened application field while developing new equipment with upgraded technical and economic indices and while studying astral system. 2 cl, 20 dwg
