  1. 1. Increasing the diodicity of ceramic Tesla valves by exploiting the design freedom of additive manufacturing : A study in design optimizations of Tesla valves for ceramic 3D printing

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Udit Sharma; [2024]
    Keywords : additive; manufacturing; Tesla; valve; ceramic; 3D; printing;

    Abstract : The work presented in this thesis was conducted at Uppsala University and at Fraunhofer IKTS, Dresden. The thesis aims to study design optimizations for increasing the diodicity and thereby performance of a Tesla valve, a type of “no moving parts” (NMP) valve, through design freedoms offered by ceramic additive manufacturing.

  3. 2. Conjugate Heat Transfer Analysis of HPGP Thruster

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Lisa Svensson; [2024]
    Keywords : aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Abstract : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. READ MORE

  4. 3. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Antoni Eritja Olivella; [2024]
    Keywords : SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Abstract : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. READ MORE

  5. 4. Pulse-width voltage modulation in the Python-based open-source simulator Motulator : A Realization of SVPWM, Harmonic analyzer and Over-modulation on Two and Three-level Inverters, and a Solution for Unbalanced Neutral Point Voltage on Three-level Inverters

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

    Author : Jiale Deng; [2023]
    Keywords : Three-level inverters; over-modulation techniques; space vector modulation; neutral-point voltage balancing; non-uniform Fourier transform; Trenivåväxelriktare; övermodulation; spacevektormodulering; balansering av nollpunktsspänning; olikformig Fouriertransform;

    Abstract : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. READ MORE

  6. 5. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

    University essay from KTH/Kraft- och värmeteknologi

    Author : David Fredouelle; [2023]
    Keywords : Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

    Abstract : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions. READ MORE
