1. 1. Aerodynamic Analysis of Reflex Airfoils at Low Reynolds Numbers

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Alexander Elliott Meyer Ströborg; [2022]
   Keywords : low Reynolds number; reflex airfoils; CFD; XFOIL;

   Abstract : Low Reynolds number airfoil analysis has become increasingly significant as urban air mobility vehicles and unmanned aerial vehicles surge in popularity. The Green Raven project at KTH Aero aims to use reflex airfoils where little data is available beyond classical analysis. READ MORE

3. 2. Development and Use of System Modeler 6DOF Flight Mechanics Model in Aircraft Conceptual Design

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Niko Erä-Esko; [2022]
   Keywords : Aircraft Conceptual Design; Flight Mechanics; Modelling and Simulation;

   Abstract : This thesis presents a tool for conceptual design of a traditional configuration aircraft by using a parametric six degrees of freedom (6DOF) flight mechanics model implemented in the Modelica Language using Wolfram System Modeler. Being first only able to model and simulate the uncontrolled flight of an aircraft with fixed mass and centre of gravity (CG), and requiring detailed aerodynamic parameters as an input, the 6DOF model is improved by developing new features to reduce the number of required inputs while also increasing the data output of the simulations.

4. 3. An aeroelastic prediction model for slender wings in supersonic flow

   University essay from KTH/Flygdynamik

   Author : Zakarias Priebe; Alexander Hasp Frank; [2021]
   Keywords : ;

   Abstract : Aeroelasticity is a multidisciplinary subject encompassing several fields of study. Aeroelastic behaviour is defined by the relation between inertial-, elastic- and aerodynamic forces that appear in dynamic systems in steady- or unsteady conditions. READ MORE

5. 4. Development of a Tool for Inverse Aerodynamic Design and Optimisation of Turbomachinery Aerofoils

   University essay from KTH/Flygdynamik

   Author : Berkin Kurtulus; [2021]
   Keywords : Aerodynamics; Turbomachinery Airfoil design; Inverse Design Automation; Airfoil Optimization;

   Abstract : The automation of airfoil design process is an ongoing effort within the field of turbo-machinery design, with significant focus on developing new reliable and consistent methods that can meet the needs of the engineers. A wide variety of approaches has been in use for inverse airfoil design process which benefit from theoretical inverse design, statistical methods, empirical discoveries and many other ways to solve the design problem.

6. 5. Numerical simulation and experimental validation of a manufactured wing profile

   University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

   Author : Niklas Olsson; Christian Selberg; [2019]
   Keywords : Flow; surface roughness; airfoil;

   Abstract : The background for this thesis originates from a study of the flow characteristics for an airfoil of the type NACA0018. The aim for this thesis was to evaluate how the characteristics of the flow over the NACA0018 profile depend on surface roughness. READ MORE
