Disclosed are a method and a device for control of perturbed motion of an elastodeformed carrier rocket around the center of mass. A method includes determining by airborne means during flight the current values of the angular deviations of the axial line of the rocket body as a perfectly rigid body, the speed and acceleration of their change in the places of installation of controls, forming in the stabilizing device based on the data of a control signal, its multiplication and injection on the drives of controls performing generation of the power factors to ensure the compensation of bending vibrations of the body of a carrier rocket. The current elastic deformations of the rocket body structure are also measured at points along its generators, according to the measurements the real current shape of bending of the centreline of the body is restored and followed by definition of its deviation from the centerline of the rocket body as a perfectly rigid body, speed and acceleration of their changes along entire length of the carrier rocket and on their basis a control signal is generated for the drive of controls. The device comprises measuring tools, an amplification device and a conversion device of their signals into the control signals, which are fed to the drives of controls, which are intended to compensate for the bending vibrations. The measuring tools are made in the form of strain gauges mounted on the structural elements of the rocket body at points along its generators. |
