  1. 1. Power Extraction in Military Aircraft

    Author : Daniel Rosell; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; engine performance; mixed flow; turbofan engine; low bypass ratio; Fighter aircraft performance; power extraction;

    Abstract : Military aircraft require more and more power. Pneumatic and hydraulic systems are being replaced by electrical equipment and new, power consuming equipmentis introduced in the aircraft. Increased power extraction brings new challenges for the aircraft jet engine, both in terms of operability and with regards to engine performance. READ MORE

  2. 2. Towards Intelligent Power-System Monitoring: Segmentation, Feature Extraction, and Identification of Underlying Causes

    Author : Cuong Le; Chalmers University of Technology; []
    Keywords : harmonics analysis; Power-system monitoring; segmentation; power-system measurement; power quality; event analysis; signal-processing applications;

    Abstract : The increase in size of modern power systems together with the concept smart grid requires advanced monitoring to ensure system availability, reliability, and power quality. The huge amount of available data no longer permits analysis to be implemented manually and centrally. READ MORE
