2. 1. Towards intuitive interfaces

   Author : Otto Carlander; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Radio Communication; Fighter Jet; Tactile; Combat Vehicle; Multimodal; Command Operators; 3D audio;

   Abstract : Operators like fighter pilots, combat vehicle drivers and fire and rescue command operators handle considerable amount of information during mission critical activities. The increasing complexity of the information landscape calls for alternative information presentation. READ MORE

4. 2. A Study in Jet Engine Control Control Structure Selection and Multivariable Design

   Author : Melker Härefors; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CSD; multivariable control; gain-scheduling; modelling; jet engine; anti-windup; control structure design; H sub infinity control;

   Abstract : Turbojet engines are becoming increasingly complex, with more control variables, to meet future demands on performance, fuel consumption and functionality. To utilise the potential of these engines, it is also necessary to use more advanced control concepts than conventionally used today. READ MORE

5. 3. Large Eddy Simulation for the Analysis of Supersonic Jet Noise Suppression Devices

   Author : Markus Olander Burak; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluidic injection; mixer-ejector; jet noise; Kirchhoff; forward flight effects; LES; acoustic liner; supersonic turbulent jets; broadband time-domain impedance boundary condition; chevrons; shock-associated noise; CAA; aeroacoustics;

   Abstract : Stricter noise regulations for commercial and military aircraft have increased interest in noise reduction techniques within the aerospace industry. To meet the requirements, new noise suppression technologies have to be developed and numerical methods need to be validated and possibly improved for the correct assessment of these technologies.

6. 4. Power Extraction in Military Aircraft

   Author : Daniel Rosell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

7. 5. Laser-Induced Emission Techniques for Concentration and Temperature Probing in Combustion

   Author : Gustaf Särner; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermographic phosphor; phosphor; phosphorescence; Laser Combustion Diagnostics; Laser-Spectroscopy; LIF; spectroscopy; Thermometry; LIP; Laser-Induced Fluorescence;

   Abstract : The work in this thesis is aimed at the development of temperature and gas concentration measurement techniques in laser diagnostics for use in combustion research. The techniques are developed as tools for the combustion community to meet future demands on combustion efficiency and legislation of exhaust gases. READ MORE
