The article considers the types of a compact gyroscopic angular rate measurement, which were designed and developed in Kuznetsov Research Institute for Applied Mechanics. The devices are based on the dynamically adjusted gyroscope with a rotor gas-lubricated spin-axis bearing system. Two types of the compact gyroscopic angular rate measurement are intended to Russian space crafts. Third of them are intended to the foreign space crafts. Three gyros are sensing elements for the compact gyroscopic angular rate measurement. Disposition of gyro into gyroscopic is the main difference of these types of the compact gyroscopic angular rate measurement. The main goal of this article is to make a research of mechanical influences on the compact gyroscopic angular rate measurement and to create the protecting systems of gyro from the mechanical influence on a new gyroscopic device. The article considers the main technical characteristics of gyroscopic device: dimensions, weight, accuracy of measurements, and number of measuring axes, resource of work device, energy consumption and so on. The paper describes advantages and disadvantages of the dynamically adjusted gyroscope with a rotor gas-lubricated spin-axis bearing system. There are the following advantages: dimensions, weight, accuracy of measure-ments, and number of measuring axes, resource of work device. The disadvantage is a necessity to protect systems from the mechanical influence on launching rockets. The article considers the main principles of protecting systems. It’s about a theoretical model system of protection of the gyroscopic device from mechanical resistance and theoretical information. Due to a theoretical model it’s possible to choose constructional characteristics of the protecting system from mechanicals influences during a design stage. It’s about dimensions spring and damper. Criterion for the choice is acceptable for the dynamical characteristics of gyro. The article has also saved the results of the mechanical test of the gyroscopic device.
Keywords: angular orientation, gyroscopic device, protection systems from mechanical influence.
