1. 1. Exterior ballistics analysis for rocket propelled KE-penetrator - A conceptual simulation study within fluid mechanics and flight mechanics

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Emil Wegberg; [2022]
   Keywords : Exterior ballistics; fluid mechanics; high-speed aerodynamics; CFD; RANS; conceptual design; Ytterballistik; strömningsmekanik; höghastighetsaerodynamik; CFD; RANS; konceptuell design;

   Abstract : 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.

3. 2. Numerical Study on Aerodynamic Drag Reduction on a Rear Wing of a Formula Student Car

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Mahim Ahsan; [2021]
   Keywords : ;

   Abstract : 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. READ MORE

4. 3. Vertical landing flight envelope definition

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Jack Charles Hooper; [2020]
   Keywords : trajectory optimization; pseudospectral; optimal control; re-entry; high speed aerodynamics; high angle of attack;

   Abstract : 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. READ MORE

5. 4. Design of a drone system for maritime search and rescue missions

   University essay from KTH/Flygdynamik

   Author : Emil Pettersson; [2020]
   Keywords : Sea Rescue; Drone; Flying Wing; Blended Wing Body; SAR; Tailless; BWB; XFLR5; Search and Rescue; Drönare; Flygande Vinge; Sjöräddning; Eftersök; XFLR5;

   Abstract : 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. READ MORE

6. 5. Direct Lift Control of Fighter Aircraft

   University essay from Linköpings universitet/Reglerteknik

   Author : Philip Öhrn; Markus Åstrand; [2019]
   Keywords : direct lift; direct lift control; fighter aircraft; model predictive control; linear quadratic control; MPC; LQ; flight path angle;

   Abstract : Direct lift control for aircraft has been around in the aeronautical industry for decades but is mainly used in commercial aircraft with dedicated direct lift control surfaces. The focus of this thesis is to investigate if direct lift control is feasible for a fighter aircraft, similar to Saab JAS 39 Gripen, without dedicated control surfaces. READ MORE
