“…The same kind of technical solutions can be used to protect electronic equipment from the penetration of high-frequency radiation from outside. In recent years, optical current and voltage transformers have appeared on the market of electric power equipment [10], which are available for all voltage classes, for example, Canadian transformers NxtPhase (www.nxtphase.com), which, along with fiber-optic lines instead of electric wires, can significantly reduce the influence of powerful electromagnetic radiation.…”

The article draws attention to the problem of protection, ensuring survivability in the face of electromagnetic terrorism and, due to the lack of universal means of protection, the importance of developing a methodology of the justification of requirements and calculation of effectiveness of existing means of protection, taking into account the energetic capabilities of means of electromagnetic terrorism.A generalized stochastic model and criterion for the effectiveness of the operation of radio-electronic means (REM) in the conditions of electromagnetic terrorism has been proposed. The basic calculation rations for the determination of the ways and composition of the means of protection, depending on the energy parameters of the means of electromagnetic terrorism, have been given.The main requirements for the protection of means of protection of radio-electronic equipment of energetic objects from the terroristic influence by electromagnetic radiation have been formulated.

“…From expression (15) evidently, that the increase of initial concentration of electrons in an interval will result in the decline of tension of electric-field. In addition, the increase of initial concentration of electrons results in less dependence of tension of electric-field on pressure of air [8,10,12].…”

The composition of airborne equipment is analyzed. It Indicates the need to solve the problem of protecting the board radio electronic means from the effects of powerful electromagnetic radiation.The article uses natural technologies to protect structural openings and board radio electronic means inputs from the effects of electromagnetic radiation. Board radio electronic means protection device was developed. Analytical conditions for board radio electronic means protection have been determined. Discharge criteria for guaranteeing board radio electronic means protection are proposed. It takes into account the powerful electromagnetic radiation parameters and the state of the ionized medium in the discharge point.

“…In physical experiments for plasma formations generation in supersonic flows, energy input is usually realized in unsteady modes [12,13], and the pulseperiodic mode is the common one. Shock mitigation and drag reduction by pulsed energy computationally, and flow separation control by a plasma actuator with nanosecond pulse periodic discharge, and bow shock wave structures control by pulse periodic energy input were investigated in references [21] to [23], respectively.…”

The theory of pulse periodic energy addition to hypersonic airflow off a vehicle to increase air mass capture and improve the performance of hypersonic inlets at Mach numbers below the design value is explored. The unsteady numerical simulation of hypersonic inlets with energy addition was performed, and pulse periodic energy addition was introduced to discuss the possibility of the steady performance improvement of hypersonic inlets. The numerical simulation of hypersonic inlets at different pulse periodic energy addition rates was carried out. The simulation result shows that the performance parameters are improved at pulse periodic than at fixed values for the same averaged energy addition, and the energy addition rate needed is less at pulse periodic than at fixed values for the same performance parameters of hypersonic inlets.
