1. Exterior ballistics analysis for rocket propelled KE-penetrator - A conceptual simulation study within fluid mechanics and flight mechanics
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : This study has investigated the conceptual feasibility of a rocket propelled kinetic energy penetrator (KEP), designed for the handheld recoilless rifle Carl-Gustaf® 84 mm calibre system, from an exterior ballistics perspective. The methodology is based upon evaluating the aerodynamic properties of different conceptual design proposals through CFD-simulations and then performing trajectory analysis to assess their exterior ballistic performance.

2. Numerical Study on Aerodynamic Drag Reduction on a Rear Wing of a Formula Student Car
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The importance of aerodynamics in racing has increased substantially over the past decades. Racing vehicles utilize different aerodynamic devices, to redirect the airflow around the vehicle in a beneficial way. The increase in downforce using an aerodynamic wing package increases drag force. LÄS MER
3. Vertical landing flight envelope definition
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : This paper will investigate the development of a landing footprint for a re-entry vehicle. Vehicles can re-enter the atmosphere with a range of orientations, velocities and flight path angles. LÄS MER
4. Design of a drone system for maritime search and rescue missions
Master-uppsats, KTH/FlygdynamikSammanfattning : The work summarized in this report aims to investigate how a drone airplane design can be optimized to create a safer and more efficient sea rescue by providing staff with an early picture, performing search missions and aiding communication through visual contact. A flying wing is in theory one of the most efficient designs for a fixed wing aircraft, at the same time as it also offers high structural efficiency for its given size. LÄS MER
5. Fordonsdynamiska effekter av en justerbar multi-element vinge jämfört med en single-element vinge för sportbilar - En teoretisk studie
Kandidat-uppsats, Mälardalens högskola/Akademin för innovation, design och teknikSammanfattning : Sportbilsbranchen har utvecklats i flera decennier och det råder en konstant efterfrågan för nya idéer och teknologier som kan förbättra sportbilar. Detta stämmer framförallt in inom superbilsbranchen, där det är en stor konkurrens mellan företag om vem som först utvecklar nya teknologier som gör deras bilar till de attraktivaste på marknaden.
