1. 11. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Vikramjeet Das; [2023]
   Keywords : rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

   Abstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE

3. 12. Development of onboard software for KvarkenSat

   Abstract : This Master thesis work presents the design, development and testing of theonboard software for the KvarkenSat CubeSat project by the Kvarken SpaceCenter. Traditionally software design in the space sector is done with a designdriven method. READ MORE

4. 13. Design and Evaluation of an Automated Pyro Cutter System for Stratospheric Balloons

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

   Author : Leia Nummisalo; [2023]
   Keywords : Stratospheric balloons; PCB; Recovery system; CNES; pyro cutter;

   Abstract : This thesis describes the development of an autonomous recovery system for stratospheric balloons, focusing on the novel pressurised balloon prototype BALMAN of CNES. Stratospheric balloons, reaching altitudes of up to 40 km, are utilised for scientific experiments, with recovery of payloads being a critical aspect. READ MORE

5. 14. Autonomous Quadcopter Landing with Visual Platform Localization

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

   Author : Martin Blaszczyk; [2023]
   Keywords : UAV; Autonomy; Landing; Fiducial markers; QR; QR-code; Drone; Platform; MPC; UAV control;

   Abstract : Multicopters such as quadcopters are a popular tool within industries such as mining, shipping and surveillance where a high level of autonomy can save time, increase efficiency and most importantly provide safety. While Unmanned Aerial Vehicles have been a big area in research and used in the mentioned industries, the level of autonomy is still low. READ MORE

6. 15. Improving Dependability of Space-Cloud Payload Processor by Storage System

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Hassan Said; Stephanie Liza Johansson; [2023]
   Keywords : Fault tolerant; Markov analysis; Onboard processing; SSD array architecture; SSD; EDAC; RAID; Hamming code; Reed Solomon; Dependability evaluation; File systems; ZFS; Ext4.;

   Abstract : Due to the usage of complicated platforms and current high-performance space computing technology, onboard processing in small satellites is expanding. Space-cloud payload processors with Commercial Off-The-Shelf (COTS) components, that are required to be radiation-tolerant, are used to perform the onboard processing. READ MORE
