The authors consider approaches to creation of security features for information and telecommunication equipment in an unmanned space vehicle (SV) with electromagnetic launch. It is shown that the main element of the microelectromechanical sensor element - the key - is a beam with a loaded core. The authors provide theoretical calculations and a table of geometric dimensions of sensor elements for two thresholds achieved with electromagnetic starting of SV - 2500 and 3000 acceleration of gravity of free fall (g). The authors consider MEMS key manufacturing technology and propose several ways to make them. The results of experimental studies under static and dynamic g forces are also presented in the article.

The article covers realization of a device for synchronous generator-field control. It is shown that the proposed device is meant for transient response data optimization in electric generators due to adaptation of the field regulator parameters to the current state of power system. The device is able to adapt the parameters of the operational unit (regulator) to the parameters of electrical power network by means of continuous teaching during the operation.

The authors consider realization of an electric generator control unit for weakening adverse effects of overloads or transient processes. The authors review the work of the regulation characteristic calculator on the basis of using an ultra-fast annealing algorithm. It is shown that the device is capable of solving problems of decreasing the energy of transient processes (which appear during disturbances in power grids) due to the parameter optimization of the field regulator of the synchronous generator according to the variation of primary voltage at the installation stage.
