Abstract:
Nowadays rocket and space industry enterprises use a simplified method to evaluate failure and fault tolerance of the onboard equipment to single event effects (SEEs), when the calculation is performed for the minimum mass protection thickness (g/cm2 ) of potentially sensitive electronic components determined, as a rule, by the minimum wall thickness of the device under consideration. In this case, all structural elements of the onboard equipment, spacecraft, and neighboring devices are not included, which, in many cases, leads to a significant overestimation of the calculated SEEs frequency especially for large scale integration ICs. Neglecting the actual mass protection may require redundant measures to ensure failure and fault tolerance. The work proposes an improved approach of calculating failure and fault tolerance of sensitive electronic components and onboard equipment to the impact of heavy charged particles and high-energy protons that causes SEEs, which consists in using programs for calculating absorbed doses by the sectorization method in three-dimensional models, which makes possible to determine the minimum, maximum, and average mass protection of electronic components with the complete design of the onboard equipment and spacecraft.

Abstract:
During the flight, charged particles of outer space act on space systems (orbital stations, spacecraft, interplanetary spacecraft, etc.), which, without the use of special protection measures, can lead to the failure of onboard systems. They are particularly dangerous for systems that use electronic components (semiconductor devices and integrated circuits, optoelectronic devices). These systems in the spacecraft, as a rule, include all control systems, telemetry systems, receiving and transmitting devices, thermal control systems, power supply systems, etc., which in general can be called radio-electronic equipment (REE).

Abstract:
The paper analyzes the electromagnetic (EM) radiofrequency (RF) radiation hazards onboard a ship arising from shipboard radiocommunication and navigation equipment. EM field effect on personnel and equipment can be harmful if field levels exceed the threshold values. These fields need to be controlled for proper protection. Ships are equipped with lots of EM RF radiation sources with different frequencies and output power levels. Typical shipboard EM RF radiation sources include: terrestrial radiocommunication transmitters, navigational radars and satellite ship earth stations (SES). Examples of these sources are analyzed in the paper. EM field estimation using simple worst-case calculation is given for a typical HF transmitter, X-band navigational radar and the Inmarsat SES A, B, C, F and M. The estimation problems are discussed. The calculation results are compared with international civil and military standards. The results show that potential hazards exist and that a reasonable amount of caution is needed.

The article presents results of researches and the analysis of means of unauthorized access and Directors of hindrances to means of communication and navigation of aircraft. It also shows that the issue of protecting automated systems of aviation equipment from threats to information security is becoming increasingly important in the context of an increase in the level of automation for prospective aircraft engines, onboard equipment, systems and units of aircraft, an increase in the complexity of onboard information systems. There is an analysis in the means of electronic warfare, capable of influencing the flight of an aircraft, both intentionally and unintentionally. There also is a statistical inference of aviation accidents on various aircraft flight phases. The airplane mathematical model constructed taking into account hindrances and harmful impacts on the onboard equipment is developed. Static stability of the plane longitudinal movement taking into account the external environment is investigated. The article gives results of a numerical experiment showing offered mathematical model high degree of adequacy. The materials of the publication contain the results of theoretical research and numerical experiment conducted using a mathematical model of the dynamics of controlled flight of the aircraft under the action of both natural noise and intentional harmful effects on the means of communication and navigation of AIRCRAFT, as well as hacker attacks on onboard computing facilities. The model is implemented in Matlab/Simulink, which allows building a workstation simulator. That in turn allows for taking into account the “human factor” when modeling the flight of an aircraft.

This article analyzes the conditions of operation and exploitation of the ship's power equipment using the meteorological conditions and the type of ship. Based on the naval power systems and new shipbuilding technologies,we are looking for optimization and increased reliability of shipboard automation and navigation systems that are on board. The article analyzes and presents solutions about the complex problems that arise in the work of the engineer that is on board. It is demonstrated the importance of the quality indicators of the naval power system for improving the operating conditions of the existing plants and to modernize the ship by providing new equipment and computers whose optimal working is influenced by the quality of the electrical energy that is onboard. In this paper it is followed the ranking of the implemented control, monitoring and protection of the electrical energy system and the propulsion power of the systems, in which the physical and functional integrity is a vital design philosophy. This can be centralized or distributed by the computers. The study of the waves is done in order to estimate the induced demands in the structure of the ship and their influence on the equipments and the devices that are on-board. The analysis is performed using experimental and theoretical values as input data in the analysis with finite elements. For the estimation of structural strength of the ship and on-board equipment it is necessary to determine the extreme values of the wave-induced loads

Abstract:
Introduction. The article presents results of a study on the hygienic evaluation of the impact of levels of electromagnetic fields (EMF) from electrical equipment, communications and navigational aids on modern automated ice-breaking vessels to the electromagnetic safety of the crew. Material and methods. The instrumental measurement of EMF levels from power equipment, electronic equipment, computers, were conducted in places of a permanent and temporary stay of the crew watches in parked icebreakers in the port and during sea trials. The assessment of the levels of electromagnetic radiation from the antennas of radio relay stations (radar) was conducted using the forecasting parameters of the EMF. Results. Onboard computers, marine electrical, communications and radar transmitters do not create electromagnetic fields exceeding the RC in crew workplaces of ship premises. Levels of EMF SHF range generated by RADAR antennas on the open deck, also do not exceed RC. Electromagnetic fields exceeding the RC are registered at work communications transmitters VHF, MF/HF on the decks of the installation of antennas transmitting devices. Discussion. There is a relevant matter of the protection of the crew from the EMF generated by the antennas of modern radars. Evaluation of the EMF RADAR intensity is only possible on the basis of data on forecasting levels of the electromagnetic radiation. To protect the crew from the EMF generated by antennas means the marine radio and RADAR on open decks should implement measures to limit exposure time to install warning signs and placards. Conclusions. There is required the improvement of normative-methodical documents in the field of the protection of the crew from the EMF. You must create a measurement technique for recording the intensity of electromagnetic radiation from the radar. Research data can be used for the development of science-based sanitary-epidemiological requirements for electromagnetic safety of the crew.

Abstract:
This paper deals with a design and implementation of optical defensive device for protection of aviation personnel. The design is built on the basic characteristics of human eyesight, illumination sensing of the environment, and microcontroller implementation for adaptation over sensed power, flash duration, and person distance. The aviation safe LED-based optical dazzler equipment (ASLODE) utilizes light emitting diode (LED) technology implemented with constant current regulators to control several modes of effects based on situational sensing. The temporarily incapacitating device can be extended by means of real-time illumination sensing to improve power efficiency and reach the highest level of safety. The smart pulse sets the flashing frequency from 8Hz for high-level light intensities and up to 20 Hz in low-level lighting conditions. Experimental results demonstrate the effectiveness of the ASLODE device over numerous experiments with controlled onboard aircraft scenarios that adapt the energy, flash rate, and processing to the sensed environmental illumination to meet aviation hygienic standards for people without eyesight defects.

Abstract:
Currently, the problem of reducing noise in electrical equipment is important, because a noise in the system affects its components and can cause unpredictable behavior of the electrical system. This is especially important onboard of unmanned aerial vehicle (UAV), where all components are located close to each other and their noise has a significant cross-effect. Conductors passing through a noisy environment can pick up a noise and direct it to another circuits, where it creates interference. Some examples of such noise problems are: degraded accuracy characteristics of microcontroller modules (Analog-to-Digital Converters (ADC), Phase-Locked Loops (PLL) and other) due to noise on supply and reference voltages, wrong acquisition of the digital signals and interference with global navigation satellite system (GNSS) or remote control system of UAV. This article is dedicated to the research of the influence of electrical noise, which is formed by the components of the UAV control system (engines, electric motor controllers, microcontroller etc.), on the performance and noise protection of electronic components of the UAV control system. After the research it was concluded that the main sources of elecrtrical noise in the UAV control system are: high currents, consumed by electronic speed controllers (with motors), high-speed toggling of clock signal of SPI / I2C communication, regulation by step-down voltage regulator and internal processes inside the microcontroller due to work of flight control firmware. The waveforms of generated noises, caused by each source was measured with oscilloscope and depicted in the article.

Abstract:
The transition to the leaky design of the instrument compartment of the spacecraft inevitably leads to additional thermal loads on the components of the onboard electronic equipment due to a change in the heat transfer scheme. The thermal mode of operation of the onboard radio-electronic equipment of the spacecraft is one of the important factors for ensuring the long term active existence of the spacecraft. Ensuring the long term of active existence of spacecraft is the most important scientific, engineering and economic task, the solution of which requires a deep systematic approach at all stages of the creation and operation of onboard electronic equipment of the spacecraft. The strategic objective for ensuring the long term of the spacecraft’s active existence is the implementation at all stages of the life cycle of onboard radio-electronic equipment of the highest achievable reliability indicators through the using of modern design and technological solutions, as well as effective methods for its design and production. This article presents the results of experimental work to reduce heat transfer resistance between onboard electronic equipment and the spacecraft’s thermal control system. As a result of the work, the main data were obtained on improving the heat sink efficiency of the energy-converting equipment of the spacecraft, the effectiveness of measures to ensure heat removal of the onboard radio-electronic equipment of the spacecraft was confirmed.

Abstract:
La protection du matériel électronique embarqué est devenue un enjeu majeur pour assurer la sécurité du combattant. On peut citer divers exemples tels que la protection des piles à hydrogène dans les véhicules ou dans la batterie embarquée d'un soldat. C'est dans ce contexte que s'inscrit la thèse, où une étude est menée sur une protection de type multi-couches, sollicitée par des projectiles de type fragment, de quelques kilogrammes, allant à des vitesses de l'ordre de 10 m/s. Afin d'assurer la mise en service de telles protections, des essais et des simulations doivent être menés sur un large champ de sollicitations. La littérature montre que les structures multi-couches offrent un bon compromis entre capacité à absorber l’énergie d’impact et légèreté. Le complexe étudié pour cette thèse est composé d’une couche métallique, acier ou aluminium, et d’une couche de polymère. La première partie de cette thèse est consacrée à la caractérisation des plaques métalliques étudiées pour cette thèse : acier DP450 et aluminium AA2024-T3. Un nouvel essai de cisaillement séquencé est proposé afin d’identifier le comportement de la tôle en grande déformation. L’essai de traction à déformation plane est adapté pour identifier la déchirure des tôles en dynamique, jusqu’à des vitesses de déformation de l’ordre de 200/s. La deuxième partie est consacrée à l’identification complète d’une nouvelle résine polydicyclopentadiene (PDCPD) appelée Nextene. Dans la dernière partie, différentes structures multicouches sont sollicitées par des impacts à l’aide d’une catapulte qui projette des projectiles de 2.5 kilogrammes à une vitesses de 10 m/s. Leurs comportements respectifs à l’impact sont comparés et simulés numériquement
The protection of onboard electronic equipment has become a major issue in ensuring the safety of the combatant. We can cite various examples such as the protection of hydrogen cells in vehicles or in a soldier's onboard battery. It is in this context that the thesis is being carried out, studying multi-layers type of protection, solicited by fragment-type projectiles, weighing a few kilograms and at speeds of the order of 10 m/s. In order to ensure the commissioning of such protections, tests and simulations must be carried out over a wide range of stress states. The literature shows that multi-layer structures offer a good compromise between the ability to absorb impact energy and lightness. The studied sandwich is composed of a metallic layer, steel or aluminium, and a polymeric layer. The first part of this thesis is devoted to the characterisation of two sheet metals, namely a DP450 steel and AA2024-T3 aluminium alloy. A new sequenced shear test is proposed to identify the behaviour of the plate at large strains. The plane strain tension test is adapted to identify the dynamic failure of the sheets at strain rate up to 200/s. The second part is devoted to the complete identification of a new PDCPD resin called Nextene. An experimental campaign is carried out in order to identify the parameters of the SAMP behaviour law in the LS-Dyna software. In the last part of the study, structures are subjected to impacts in a catapult, using a 2.5 kilogram projectile at a speed of 10 m/s. Various combinations of sandwiches are compared, and the numerical simulation of the tests is proposed

Abstract:
Over the past decade, the satellite industry has witnessed the birth and evolution of the CubeSat standard, not only as a technology demonstrator tool but also as a human capacity development platform in universities. The use of commercial off the shelf (COTS) hardware components makes the CubeSat a cost effective and ideal solution to gain access to space in terms of budget and integration time for experimental science payloads. Satellite operations are autonomous and are essentially based on the interaction of interconnected electronic subsystems exchanging data according to the mission requirements and objectives. The onboard computer (OBC) subsystem is developed around a microcontroller and plays an essential role in this exchange process as it performs all the computing tasks and organises the collection of onboard housekeeping and payload data before downlink during an overpass above the ground station. The thesis here presented describes the process involved in the development, design and implementation of a prototype OBC for a CubeSat. An investigation covering previously developed CubeSat OBCs is conducted with emphasis on the characteristics and features of the microcontroller to be used in the design and implementation phases. A set of hardware requirements are defined and according to the current evolution on the microcontroller market, preference is given to the 32-bit core architecture over both its 8-bit and 16-bit counterparts. Following a well defined selection process, Atmel’s AT91SAM3U4E microcontroller which implements a 32-bit Cortex-M3 core is chosen and an OBC architecture is developed around it. Further, the proposed architecture is implemented as a prototype on a printed circuit board (PCB), presenting a set of peripherals necessary for the operation of the OBC. Finally, a series of tests successfully conducted on some of the peripherals are used to evaluate the proposed architecture.

Abstract:
The continuous development of space missions has put forward requirements for high performance, high reliability, intelligence, effective integration, miniaturization, and quick turn around productization of the electronic system of satellites. The complexity of satellites has continued to increase, and the focus of satellite competition has shifted from the launch of success shifts to communication capacity, performance indicators, degree of flexibility, and continuous service capabilities. So, the importance of onboard avionics system is becoming increasingly prominent. In the future, the advanced avionics system integrates most of the platform’s electronic equipment. The design level of the system largely determines the performance of the satellite platform. This chapter focuses on the application requirements of the new generation of intelligent avionics system for future communication satellites and adopts an “open” architecture of “centralized management, distributed measurement and drive, and software and hardware ‘modular’ design” to build a universal, standardized, and scalable intelligent avionics system.

Abstract:
Several Authorities are procuring Hybrid Streetcars with OESS. The energy storage system needs to be protected from ground faults, external and internal to the vehicle. A Hybrid Streetcar has an OESS consisting of either Lithium Batteries or super capacitors, with an OESS converter connected to, or integrated with, the Traction Inverter. During a ground fault of the high voltage circuit, the freewheeling diode in an OESS charger creates a fault path between the energy storage elements and ground. Typical vehicle designs use a fuse for catastrophic protection, depending on the vehicle ground fault scheme for detection and protection. The vehicle’s primary ground fault detection device is an HSCB, usually connected between the shop switch and traction inverter; the auxiliary inverter is typically protected using a fuse. An HSCB is able to protect typical fault currents seen within the traction chain, but is not designed for OESS fault currents. If a fault occurs the fuse for the catastrophic protection of the OESS will blow before the HSCB will trip, potentially damaging equipment, making the vehicle inoperable. This paper compares alternative methods which can be deployed to detect and protect the OESS from a ground fault.

Abstract:
A practical and innovative solution to answer the need for power in freight cars is presented. The lack of available electric power in the vast majority of freight cars limits the use of electronic devices such as measuring (sensor) systems, GPS tracking devices or active RFID tags. An energy harvesting system has been developed to keep a battery charged and electric equipment running. The basic idea is to generate power using the relative motion of the car suspension as an input, scavenging energy that is normally wasted as heat in the damping system. Based on a promising first generation unit used as a proof of concept, the current prototype is designed to fit inside a typical suspension spring (D5) and so, can easily be implemented in virtually any rail car. During laboratory tests, the system is capable of efficiently generating up to 80W of power, on quasi-continuous basis, with a sinusoidal input of 3/8 inch at 2Hz. Durability tests have also been conducted to ensure that the system can withstand the harsh railroad environment. Additionally, actual suspension displacement measurements have been used to replicate real conditions and forge a more precise idea of the behavior that can be expected once implemented in a rail car. With encouraging laboratory tests, the next steps are to further validate the system and to confirm the obtained results with field testing.

Abstract:
Background: Line break controls developed to date have provided the Pipeline Industry with the best protection available with proven and available technologies. There have been shortcomings in line break control due to various factors including; lack of accurate pressure history at the valve sites creating uncertainty for proper set points and limitations in the flexibility of mechanical systems. Safety: Providing pipeline safety through a line break detection system is critically important for the protection of people, property, and the environment. Safer procedures are available through continuous pipeline monitoring. Application of new technology: Increased availability of “smart” pressure sensors offers a greater degree of accuracy and control. Real time communication for data collection and system configuration (operating data, alarm status and settings, valve status) or remote operation (valve closures or line break override) provides increased control over pipeline operations. Real time information allows continuous monitoring and control. This can be provided through commercially available networks, hence providing economical and reliable methods of communication. Data acquisition through Windows based software allows the user to accumulate, sort, and analyze the data. Overview: Industry requires the ability to monitor pipeline pressures and pipeline rate of pressure change. Industry requires accuracy, reliability, and real time access for controlling valves, while minimizing the occurrences of false valve closures. The pipeline and gas transmission industry is growing, with increasing demands for safe, reliable, and efficient operating systems. New technologies are capable of providing solutions for the Pipeline Industry’s needs. Solutions: A self-contained electronic system, purpose built for the gas pipeline industry is available. The equipment continuously monitors the pipeline, measures pipeline pressures, and calculates pressure changes so that, in the case of a pipeline failure, a command is sent to the actuator to stroke the valve to the fail safe position. The equipment is accessible locally or remotely via SCADA or telemetry to acquire and analyze pipeline conditions on a real time basis, and control the actuator. The equipment is low power consumption suitable for external line power, or is available with solar panels and rechargeable batteries. The equipment continuously gathers information and provides history for pipeline operators. This allows the optimization of set points, with time delays and averaging, to minimize false trips. Windows based software enables ease of use. Owner can set alarm parameters that are protected through password authorization. Summary: Electronic Linebreak Detection Systems are able to provide the flexibility, reliability and responsiveness necessary to meet the growing safety and efficiency demands of the Pipeline Industry. Current technology provides this capability.
