3. 12. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Kun Feng; [2023]
   Keywords : ABEP; VLEO; DSMC; FMF; Orbital Aerodynamics; ABEP; DSMC; VLEO; FMF; Orbital Aerodynamics;

   Abstract : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. READ MORE

4. 13. Design of a modular small-scale PMMA/Air hybrid rocket research engine

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Gustaf von Platen; [2023]
   Keywords : hybrid rocket engine; PMMA combustion; rocket engine design; combustion diagnostics; rocket engine; regression rate; preliminary design definition; hybrid rocket engine simulation; gaseous oxidizer; transparent rocket engine;

   Abstract : Rocket propulsion using the hybrid-propellant scheme is a technology that offers much promise in applications where high-performance liquid rocket engines are deemed too complex and solid rocket motors are considered to lack performance or safety. However, despite extensive research, there is still a lack of knowledge in the theoretical aspects of hybrid rocketry, especially in the area of fuel-oxidizer mixing and fuel regression rate.

5. 14. Measurement & Feedback Control of a Two Level System

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Sayan Ali Khan; [2022]
   Keywords : Quantum Measurement; Generalized Measurements; POVM Positive Operator Valued Measure ; Feedback Control; Two-Level System; Physics and Astronomy;

   Abstract : In this bachelor project, the main objective is to investigate how a two-level quantum system can be controlled using weak continuous measurements and feedback control. The Monte-Carlo method was used to simulate the system dynamics under measurement and feedback to investigate how the system state can be controlled. READ MORE

6. 15. Autonomous Propulsion for a GPR-UGV

   University essay from Umeå universitet/Institutionen för fysik

   Author : Fredrik Wall Eskilsson; [2022]
   Keywords : robotics; gpr; autonomous; robot; ros; slam;

   Abstract : This thesis presents the research and development behind the integration of an autonomous propulsion system for a four-wheeled Ground Penetrating Radar (GPR) measurement unit, previously requiring manual operation. In order to ease the administration of the complex new system, Robot Operating System (ROS) 2 was used as middleware, where an implementation of Light Detection And Ranging (LiDAR) 3D-SLAM (Simultaneous Localization And Mapping) served to secure precise localization of the Unmanned Ground Vehicle (UGV) and mapping of its environment.
