  1. 1. On aircraft fuel systems : conceptual design and modeling

    Author : Hampus Gavel; Petter Krus; Johan Ölvander (Andersson); Dieter Scholz; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft; morphological matrix; simulation; Saab; Gripen; Construction engineering; Konstruktionsteknik;

    Abstract : The largest and most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. READ MORE

    Author : Alireza Ahmadi; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The air transport business is large in its operations, integrated, automated and complex. Air carriers are constantly striving to achieve high standards of safety and simultaneously to attain an increased level of availability performance at minimal cost. READ MORE

  3. 3. Predictive Health Monitoring for Aircraft Systems using Decision Trees and Genetic Evolution

    Author : Mike Gerdes; Diego Galar; Uday Kumar; Dieter Scholz; Piotr Bilski; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Condition Monitoring; Remaining Useful Life Prediction; Decision Tree; Genetic Algorithm; Fuzzy Decision Tree Evaluation; System Monitoring; Aircraft Health Monitoring; Feature Extraction; Feature Selection; Data Driven; Health Prognostic; Knowledge Based System; Supervised Learning; Data-Driven Predictive Health Monitoring; Health Indicators; Machine Learning; Big Data; Pattern Recognition; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Reducing unscheduled maintenance is important for aircraft operators. There are significant costs if flights must be delayed or cancelled, for example, if spares are not available and have to be shipped across the world. READ MORE

  4. 4. Part-out Based Spares Provisioning and Management : A Study for Aircraft Retirement

    Author : Jan Block; Alireza Ahmadi; Richard Millar; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Aircraft retirement; End-of-life management; Parting-out; Part-out-based spares provisioning; Reliability analysis; Repairable units; Spare parts provisioning; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The operation and maintenance phase of a complex technical system may deal with strategicdecisions for asset retirement and end-of-life management. When a fleet of aircraft reachesthe retirement phase, the operation of remaining fleet should still be kept at a defined level ofavailability. READ MORE

  5. 5. On maintenance management of wind and nuclear power plants

    Author : Julia Nilsson; Lina Bertling; Ulf Sandberg; KTH; []
    Keywords : electrical poduction systems; windpower; nuclear power; maintenance management; RCM; RCAM; LCC; mathematical optimization; opportunistic maintenance;

    Abstract : Electrical production in Sweden today is mainly from nuclear and hydro power. However, there is large increase in renewable energy like wind power and the installed new capacity goals are large. Several electrical production sources are important for the sustainability of the energy system. READ MORE
