  2. 1. Adaptive Mesh Refinement and Simulations of Unsteady Delta-Wing Aerodynamics

    Author : Yann Le Moigne; KTH; []
    Keywords : delta wing; high angle of attack; vortex; pitching; mesh refinement; UCAV; vortex sensor; tensor ofvelocity gradients;

    Abstract : This thesis deals with Computational Fluid Dynamics (CFD)simulations of the flow around delta wings at high angles ofattack. These triangular wings, mainly used in militaryaircraft designs, experience the formation of two vortices ontheir lee-side at large angles of attack. READ MORE

  4. 2. Adaptive-fidelity CFD for predicting flying qualities in preliminary aircraft design

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

    Abstract : 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. READ MORE
