WIMAS addresses the Airborne building block of maritime surveillance with the potential for reduced cost of operation, more autonomous and improved efficiency through the introduction of air vehicles with reduced or zero onboard crew. Innovative concepts are required to support the integration of these new vehicles in a future European maritime surveillance system of systems. With 20 million km2, the surveillance of the European maritime domain has to be improved, according to the European Council, EC and Agencies such as FRONTEX. The urgent need is to control illegal immigration, but WIMAS will also contribute to other missions. You cannot control what you do not patrol. Even if cooperation is crucial, Air assets are a unique capability for wide area maritime surveillance because they provide situation awareness over extended areas (endurance, speed and long distance detection), re-direction to areas of interest (threat) and flexible reaction (inspection when needed). WiMAS will develop concepts and technologies for better operational use at lower costs of: - Maritime Surveillance Manned Airborne Vehicle (MS MAV) including existing Mission Aircraft with zero or reduced onboard tactical crew - Maritime Surveillance Optionally Piloted Vehicles (MS OPV) because regulations will not allow UAVs to fly across European Airspace for years to come. Intermediate solutions are required - Maritime Surveillance Unmanned Airborne Vehicle (MS UAV) because they will become a future key solution Supported by a User Group, WIMAS consortium will provide tangible results: - Simulation based on operational scenarios - Innovative concepts and technologies held by simulation (algorithmic modelling, remote control, sensor data fusion) - In flight experiment (remote control, crew concept) - Cost benefit analysis - Dissemination of results (workshops) - Roadmap towards the introduction of reduced-crew platforms and UAVs including R&T priorities and future programs.

CAESARIS project aims at developing a new, integrated security and search-and-rescue airborne solution conceived to detect people, both above visible and hidden behind opaque layers (like foliage, trailer covers, boat covers) or in darkness and reduced visibility conditions. This solution will work on board of an aerial vehicle making exhaustive and intelligent use of state-of-the-art sensors: Synthetic Aperture Radar (SAR) and Electro-Optical (EO) imagery in the visible range in an innovative way based on cognitive multispectral sensing. Considering the market opportunities in the field of security and search and rescue, CAESARIS team will develop a real-time configurable, plug-and-play and low Size, Weight and Power (SWaP) system that fulfils the requirements of the EU Security Agencies. Furthermore, CAESARIS will be able to detect and track targets on line of sight but also under opaque layers of materials (such as foliage, inside trucks, etc.) covering wide land and sea areas, 24/7, including bad weather conditions. Hence, the prime industrial objectives are: Development of a reconfigurable SAR sensor; Development of algorithms and software for the detection of targets hidden under non-transparent layers; Development of a software system for the automatic control of the multispectral sensing hardware in a context-aware manner; Development of a software module for the control of the cognitive multispectral sensing platform; Development of a pilot airborne platform. CAESARIS project has been built following the natural commercial relationship among companies that join forces to develop innovative and ambitious products. Therefore, the SMEs involved (Centum Solutions, MetaSensing, SmallGIS) take part in the project considering the complementary range of disciplines needed to develop CAESARIS concept. The RTD performers (Gradiant, Air Force Institute of Technology-ITWL, National Consortium for Telecommunications-CNIT) have been selected according to their key qualifications to meet project objectives and results and the complementarities between RTDs scientific excellence.

In Blade Tip Timing several sensors installed circumferentially in the casing are used to record times of arrival (TOA) and observe deflections of blade tips. This paper aims to demonstrate methodology of model-based processing of aliased data. It focuses on the blade vibration excited by the forces synchronous with engine rotation, which are called integral responses. The driven harmonic oscillator with single degree of freedom (SDOF) is used to analyse blade vibration measured by tip-timing sensors during engine deceleration. When integral engine order EO is known, the linear sine fitting techniques can be used to process data from sensors to estimate amplitude, phase and frequency of blade vibration in each rotation. The oscillator model is implemented in MATLAB and used to generate resonance curves and simulate blade responses observed with tip sensors, installed in the axial compressor. Generated TOA data are fitted to the sine function to estimate vibration parameters. The validated procedure is then employed to analyze real test data. © Radosław Przysowa 2014.

Blade Tip Timing (BTT) is a non-intrusive method to measure blade vibration in turbomachinery. Time of Arrival (TOA) is recorded when a blade is passing a stationary sensor. The measurement data, in form of undersampled (aliased) tip-deflection signal, are difficult to analyze with standard signal processing methods like digital filters or Fourier Transform. Several indirect methods are applied to process TOA sequences, such as reconstruction of aliased spectrum and Least-Squares Fitting to harmonic oscillator model. We used standard sine fitting algorithms provided by IEEE-STD-1057 to estimate blade vibration parameters. Blade-tip displacement was simulated in time domain using SDOF model, sampled by stationary sensors and then processed by the sinefit.m toolkit. We evaluated several configurations of different sensor placement, noise level and number of data. Results of the linear sine fitting, performed with the frequency known a priori, were compared with the non-linear ones. Some of non-linear iterations were not convergent. The algorithms and testing results are aimed to be used in analysis of asynchronous blade vibration. © Krzysztof Kaźmierczak et al. 2014.

The paper has been intended to present models of intervention actions launched by the rescue system and undertaken by a team carried by a means of transport. The models are expected to simulate how the undertaken actions are performed. This, in turn, would allow the assessment of crew/team's readiness to perform/accomplish the expected tasks within some fixed limits of time. Distinguished and described is a method to analyse intervention actions by rescue teams. General classification of tasks and the question of how stress affects the time to complete these tasks have also been included. An algorithm has been given to assess the process of mobilising teams for rescue actions. Furthermore, models of various intervention-action structures under crisis conditions have been presented. What else the paper submits is a method to assess reliability of an engineered means of rescue. The basis for the assessment is formed by a change of a selected diagnostic parameter. The main objective of this method is to search for the distribution of time to a failure of some specific type, characteristic of the object/device and operating conditions given consideration.

The paper presents selected highlights of the cybernetic theory of hazards. This theory is a basis for high school teaching of safety engineering. It is assumed that the theory of hazard, should be dealt with modeling and formal description of the behavior of the antropotechnical system in dangerous circumstances. As a basic tri-state systems are described: operator, mean and infrastructure of transport. The interactivity elements of system present matrices of desired and undesired incidents transition in the system multi-state threats. As an obvious aspect of the theory was qualitative and formal description unsafety characteristics. Unsafety states of antropotechnical system divided into border and critical. The critical state of the system that not less than one element of the system is in critical condition. Times attributed the occurrence of damage, making mistakes and critical impact forcing factors are treated as random variables. It is assumed that the basic characteristics of developments the dangerous circumstances are the intensity of critical failures and / or irreversible human errors. The unsafety characteristics represent a conditional unsafety probability and are associated with the coefficients of expected time to critical events.

In this work, algorithms have been used to compare the methods for determining reliability of critical points. Generalized models Stress-Strength-Interference (SSI) and Stress-Strength-Time (SST) have been analyzed. Input to the algorithms, stress and strength were generated by using the Markov chain model based on actual flight records. With this approach methods of determining the reliability of critical points of a helicopter's structure are justified.
