1. Aerodynamic Analysis of Reflex Airfoils at Low Reynolds Numbers
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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. LÄS MER
2. Enhancing the endurance of UAVs by the use of structural power composites: System-level study of a flying wing
Master-uppsats, KTH/LättkonstruktionerSammanfattning : This thesis studies the feasibility of integrating the novelStructural Battery (SB)[1] into the airframe of a UnmannedAerial Vehicle (UAV). The potential advantages in terms ofmass, range and endurance are studied.The aircraft performance is analysed using conventionalflight mechanics, modelled in Matlab and Xfoil. LÄS MER
3. Airfoil Optimization Through Differential Evolution
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : This thesis presents the development of a numerical optimization algorithm for airfoils, and how it can be used in design of wind turbine blades. It was found that the developed algorithm successfully improves the goal parameters under given conditions and constraints. LÄS MER
4. MDO Framework for Design of Human PoweredPropellers using Multi-Objective Genetic Algorithm
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : This thesis showcases the challenges, downsides and advantages to building a MultiDisciplinary Optimization (MDO) framework to automate the generation of an efficientpropeller design built for lightly loaded operation, more specifically for humanpowered aircrafts. Two years ago, a human powered aircraft project was initiatedat Linköping University. LÄS MER
5. Aerodynamisk optimering av vindkraftverks rotorblad med en genetisk algoritm, BEM-teori, och XFOIL
Kandidat-uppsats, KTH/Industriell ekologiSammanfattning : This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it’s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. LÄS MER
