1. 1. Airspeed estimation of aircraft using two different models and nonlinear observers

   University essay from Linköpings universitet/Fordonssystem

   Author : Alexander Roser; Anton Thunberg; [2023]
   Keywords : sensor fusion; flight mechanics; Kalman filter; extended Kalman filter; unscented Kalman filter; pitot tube; airspeed estimation; simulation;

   Abstract : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. READ MORE

3. 2. Functionnal Modelling and Simulation of the Off-Design Operation of a Cryogenic Engine

   University essay from KTH/Kraft- och värmeteknologi

   Author : Brice Metzinger; [2022]
   Keywords : Cryogenic propulsion; Electrical pump; Operating domain;

   Abstract : The Exploration Company is a French and German start-up that develops and operates Nyx, anorbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulationof the o-design operation of the cryogenic engine of Nyx. READ MORE

4. 3. Development of Test Methodologies and Setups for Thrust Measurements of Cold Gas Micro-thrusters for CubeSats

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

   Author : Aleksander Kipiela; [2022]
   Keywords : Thrust measurements; cold gas propulsion; micro thrusters; hanging pendulum; CubeSat; Dragkraftsmätning; kallgasframdrivning; mikrodysor; hängande pendel; CubeSat;

   Abstract : Measuring the thrust of cold gas micro-thrusters, due to the small magnitude of the generated force, is a challenging task, and to obtain satisfying quality of results usually careful adjustments of the setup has to be performed. The work presented in this paper aims at improving the quality of such measurements at the GomSpace Sweden company. READ MORE

   Abstract : The Exploration Company is a French and German start-up that develops and operates Nyx, an orbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulation of the off-design operation of the cryogenic engine of Nyx. READ MORE

6. 5. 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
