  1. 1. Validation of software for the calculation of aerodynamic coefficients : with a focus on the software package Tornado

    Kandidat-uppsats, Fluid och mekanisk systemteknik

    Författare :Ramón López Pereira; [2010]
    Nyckelord :Aerodynamic coefficients; Aerodynamiska koefficienter;

    Sammanfattning : Several programs exist today for calculating aerodynamic coefficients that with some simplifications provide fast approximations of the values for a real aircraft. Four different programs were analyzed for this report: Tornado, AVL, PANAIR and a handbook-type preliminary method. In addition, ANSYS CFX was used for airfoil validation. LÄS MER

  3. 2. Modelling & implementation of Aerodynamic Zero-lift Drag into ADAPDT

    M1-uppsats, Akademin för innovation, design och teknik

    Författare :David Bergman; [2009]
    Nyckelord :drag; zero-lift drag; aerodynamics; nollmotsånd; aerodynamik; motstånd;

    Sammanfattning : The objective of this thesis work was to construct and implement an algorithm into the programADAPDT to calculate the zero-lift drag profile for defined aircraft geometries. ADAPDT, shortfor AeroDynamic Analysis and Preliminary Design Tool, is a program that calculates forces andmoments about a flat plate geometry based on potential flow theory. LÄS MER
