Initiation of high-energy material ignition by nanosecond high-current electron beam

Results of experiments on the initiation of ignition in high-energy materials with a broad range of physicochemical parameters by high-current electron beams of nanosecond duration are presented. It is shown that ignition of these materials can be initiated even at relatively low energy parameters of the electron beam, provided that the ignition temperature does not exceed 200°C.     

Estimation and optimization of maximum deviations in dynamical control system under complexly shaped disturbances

The game problem of designing dynamical systems that are optimal with respect to extreme deviations subject to external actions is solved. The maximum (over time) of the absolute value of the function characterizing the quality of motion is used as the measure of deviation. A method for describing the set of possible external actions as a set of outputs of an additional dynamic block??a reference input generator (RIG) is proposed. The chief application domain of the results is the design of servomechanisms with the minimal extreme tracking error deviation. An example of designing a hydraulic servo drive is discussed.     

Effect of Modification of Tetryl Detonation Nanodiamonds on Combustion of Model Paste-Like Propellants

Combustion, Explosion, and Shock Waves - Detonation nanodiamonds (DND) represent a unique material combining the properties of a rather passive diamond core with an active carbon shell. The effect...
