1. 1. UV Curable Polymers for use in Additively Manufactured Energetic Materials

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexis Delorme; [2022]
   Keywords : Additive manufacturing; 3D printing; UV curing; mechanical properties; solid rocket motor; propellant; polymers; depth of cure; Additiv tillverkning; 3D-utskrift; UV-härdning; mekaniska egenskaper; fast-bränsleraketmotor; drivmedel; polymerer; härdningsdjup;

   Abstract : Fast-bränsle-raketer (SRM) har funnit sin plats i en stor mängd tillämpningar sedan deras framkomst mer än 2000 år sedan. En SRMs prestanda är förutbestämd av geometrin av drivmedelskrutet och är begränsad av gjutningsmetoden, som idag främst används i produktion. READ MORE

3. 2. Reversing the flow of heat in system of initially correlated qubits

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

   Author : Giovanni Francesco Diotallevi; Peter Samuelsson; Faraj Bakhshinezhad; [2021]
   Keywords : Qubits; Cooling; Heat Flow; Physics and Astronomy;

   Abstract : The Second Law of Thermodynamics is considered to be one of the most fundamental and important laws of Physics. Both Clausius and Kelvin reformulated the Second Law as statements concerning the behaviour of two communicating systems, set to interact at different temperatures. READ MORE

4. 3. Design, simulation, and testing of an electric propulsion cluster frame

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

   Author : Jeremy Bek; [2021]
   Keywords : Electric propulsion; gridded ion thruster; cluster; frame; thermal modelling; mechanical modelling; lumped-parameter model.; Elektrisk framdrivning; jonmotor; kluster; ram; termisk modellering; mekanisk modellering; klumpelementmodell.;

   Abstract : In general, electric propulsion offers very high efficiency but relatively low thrust. To remedy this, several ion engines can be assembled in a clustered configuration and operated in parallel. This requires the careful design of a frame to accommodate the individual propulsion systems. READ MORE

5. 4. Mechanical and structural conceptof the ISS microgravity experimentpayload: AtmoFlow

   University essay from KTH/Rymdteknik

   Author : Mathias Nicolle; [2019]
   Keywords : ;

   Abstract : This Master Thesis report presents the mechanical concept and design of a microgravity fluid science experiment that is planned to be launched to the International Space Station in approximately five years. Named AtmoFlow, this experiment aims to study the complex flow phenomena occurring in different planets’ atmosphere by implementing a scaled-down model of a planet-atmosphere system in microgravity.

6. 5. Mechanical conception of the ERICA (ERA Iron bird CLU hArdware simulator)

   University essay from KTH/Farkost och flyg

   Author : Pierre-Yves Girardin; [2017]
   Keywords : mechanical conception; ERA; robot; gantry; gimbal;

   Abstract : Sending a man in space is extremely dangerous. In order to continue the space exploration, robots have to be used. Designed properly, robots can handle any kind of operations in deep space. But in space there is no support such as an after-sale service. READ MORE
