  2. 1. Conceptual Design of Propulsion Systems for Boundary Layer Ingestion

    Author : Sebastian Samuelsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-electric aircraft; performance modeling; Aviation; boundary layer ingestion; aircraft engine; conceptual design; propulsion integration;

    Abstract : To reduce the climate impact of aviation new aircraft and engine concepts as well as improved design methods are needed. In this thesis, two fronts are explored. The first concerns improved methods for the conceptual design of the engine. READ MORE

  4. 2. On Integrity Monitoring of Integrated Navigation Systems

    Author : Jan Palmqvist; Fredrik Gustafsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In civil aviation a new philosophy for flight safety and traffic management is under development. The goal is to enable an expected increase in air traffic density by reducing aircraft separation. The accuracy of the position estimate determined by the navigation system in each aircraft determines this separation. READ MORE

  5. 3. High-Temperature Analog and Mixed-Signal Integrated Circuits in Bipolar Silicon Carbide Technology

    Author : Raheleh Hedayati; Carl-Mikael Zetterling; H. Alan Mantooth; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon carbide SiC ; bipolar junction transistor BJT ; high temperature; SiC integrated circuit; Spice Gummel-Poon SGP ; operational amplifier opamp ; negative feedback amplifier; bandgap reference; masterslave comparator; digital-to-analog converter DAC ; analog-to-digital converter ADC ; flash ADC; successive approximation register SAR ADC; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Silicon carbide (SiC) integrated circuits (ICs) can enable the emergence of robust and reliable systems, including data acquisition and on-site control for extreme environments with high temperature and high radiation such as deep earth drilling, space and aviation, electric and hybrid vehicles, and combustion engines. In particular, SiC ICs provide significant benefit by reducing power dissipation and leakage current at temperatures above 300 °C compared to the Si counterpart. READ MORE

  6. 4. Enabling engineering support for integrated product and service innovation

    Author : Peter Thor; Erik Sundin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funktionella produkter; Functional Product Development;

    Abstract : The increasing need for mobility in society alongside an intensifying concern for sustainability challenges today’s aviation industry. For companies, a Product-Service Systems (PSS) perspective puts emphasis on proving value to customers by offering a combination of hardware and services over an extended life cycle. READ MORE

  7. 5. Human Engineering of Sensor Fusion Systems in Fighter Aircraft

    Author : Peter Svenmarck; peter Wide; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A pressing concern in modern fighter aircraft cockpit design is how to present and reduce large amounts of data obtained from several sensor observations of the same object. Currently, sensor observations are presented individually as overlays or in different displays requiring the pilot to control each sensor and integrate observations. READ MORE
