1. 1. Advances in vortical flow prediction methods for design of delta-winged aircraft

   Författare :Simone Crippa; Arthur Rizzi; James Luckring; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; delta wing; slender wing; aircraft; vortex; VFE-2; CAWAPI; HISAC; Vehicle engineering; Farkostteknik;

   Sammanfattning : This thesis covers the field of vortex-flow dominated external aerodynamics. As part of the contribution to the AVT-113 task group it was possible to prove the feasibility of high Reynolds number CFD computations to resolve and thus better understand the peculiar dual vortex system encountered on the VFE-2 blunt leading edge delta wing at low to moderate incidences.

3. 2. Generalized Methods for Aeroelastic Analysis

   Författare :Jari Hyvärinen; KTH; []
   Nyckelord :Aeroelastic Modelling; Linearized Methods;

   Sammanfattning : Generalized aeroelastic methods are here defined as methodsthat allow aeroelastic analysis of problems in many engineeringdisciplines. Aeroelastic/fluid-elastic phenomena are ofsignificant importance in many industrial applications, but fewtools exist for efficient analysis of these systems. LÄS MER

4. 3. 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
