Electric drives for aerospace need a fault-tolerant design approach to achieve reliability objectives with optimized architectures reducing redundancies, over-sizing and costs. The presented work shows how fault tolerant design methodologies can be applied in two motors for typical aircraft application such as a Cart Lift System (CLS) and a Flap Actuator (FA). Analyses and tests are reported to demonstrate how the designed multi-phase motors are able to run at rated torque also with one or two phases faulted.","PeriodicalId":134406,"journal":{"name":"Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122828748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems are very important to ensure right function of other systems and whole aircraft. Every electric facility needs suitable power supply unit. Because of that power supply unit is most important for electric systems, pilot of the aircraft or operator of the unmanned air vehicle need to know status of power supply unit. The paper is aimed to the proposal of power supply monitoring unit. Voltage measuring is quite simple, so the paper is devoted to current measuring by modern technology, to process measured values, to transmit them through bus CAN (Controller Area Network) with CANaerospace protocol to aircraft cockpit and to display to the pilot or other systems.","PeriodicalId":134406,"journal":{"name":"Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128995694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coupled-inductor step-up topology can be efficient when high step-up gains are required. The paper investigates the dependence of the efficiency on design parameters for a bidirectional dc-dc converter. The sliding mode control technique has been selected for controlling the dc-dc bidirectional converter, due to its intrinsic robustness against the uncertainties and disturbances. Analytical models evaluate the power losses thus allowing to calculate the converter efficiency and to make the sensitivity analysis versus the design parameters. Spice numerical simulations, performed with respect to a simple test system, allow to verify the suitability of the proposed modeling and to capture important parasitic phenomena.","PeriodicalId":134406,"journal":{"name":"Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"85 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127431825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural health monitoring systems are widely adopted to monitor the behavior of structures during forced vibration testing or natural excitation (e.g. earthquakes, winds, live loading). They can be found in a number of civil structures, including bridges and viaducts, and also in applications of vehicle health monitoring. Moreover, since infrastructures can be damaged by human originated threats, the adoption of security measures is also essential. This paper presents a proposal of an early warning system based on Wireless Sensor Networks (WSN) for railway infrastructure monitoring. It exploits already available research results and tools for WSN management, integration and data fusion. The aim is to hedge detection capabilities in a complete framework for structural failures as well as security threats, including both natural hazards and intentional attacks.","PeriodicalId":134406,"journal":{"name":"Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"6 2-3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114036619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
