1. 6. Modelling of unsteady aerodynamics for aircraft design

   Författare :Christopher Jouannet; Linköpings universitet; []
   Nyckelord :Aircraft Deisgn; Aerodynamic; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This thesis present a simple mathematical prediction model for high angles of attack aerodynamics, including dynamic effects over delta wings, and an extension to full configuration. The model presented is intended for application in conceptual design and is extended to parameters identifications in preliminary design with validation against experimental data. LÄS MER

3. 7. Adaptive-fidelity CFD for predicting flying qualities in preliminary aircraft design

   Författare :Maximilian Tomac; Arthur Rizzi; Christopher Jouannet; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik;

   Sammanfattning : To reduce development cost and to avoid late design fixes in aircraft design, methods that are fast and economic in estimating the aerodynamic characteristics of complex flight vehicles at the preliminary design stage are desired. This work and thesis focus on the adaptive-fidelity CFD approach, with emphasis on the high end of the CFD tools available today. LÄS MER

4. 8. Birds in the Flow: Flight Mechanics, Wake Dynamics and Flight Performance

   Författare :Mikael Rosén; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Eleonora s falcon.; hunting; optimum wingspan; tail posture; wingbeat kinematics; wake topology; DPIV; flight performance; wake dynamics; flight mechanics; wind tunnel; Flight; bird;

   Sammanfattning : I share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. LÄS MER
