  1. 11. Electric Propulsion for a High Altitude Unmanned Aerial Vehicle

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jacob Hjort Friderichsen; David Jönsson; [2022]
    Nyckelord :Electric Propulsion; UAV; ALPHA; Electronic Speed Controller; BLDC Motor; Propeller;

    Sammanfattning : The catalogue of observational platforms for space and atmospheric research can be expanded by utilising drones equipped with specialised instrumentation and capable of flying at high altitudes. In this project the requirements for an electric propulsion system applicable to the KTH Royal Institute of Technology ALPHA project are evaluated. LÄS MER

  3. 12. Development Model of a Gas Pressure Regulator for Spacecraft Propulsion : Design Enhancement and Testing

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FILIPPO POZZI; MARCUS SJÖBERG; [2021]
    Nyckelord :;

    Sammanfattning : This thesis treats the testing, analysis, and continued development of a mechanical pressure regulator prototype, intended for use in spacecraft propulsion systems. Herein referred to as the Adapted Mechanical Pressure Regulator (APR), the regulator is an adaptation made by the Swedish space system developer OHB Sweden AB (OSE) of an existing patented design originally intended for use outside of the space industry.

    Sammanfattning : In recent years, the Helicon Plasma Thruster (HPT) has become one of the most promising technologies of in-space electric propulsion. T4i Technology for Propulsion and Innovation S.P.A. LÄS MER

  5. 14. Experimental Verification of BP-HiPIMS Thrusters

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :David Mainwaring; [2020]
    Nyckelord :Electric propulsion; BP-HiPIMS; Space propulsion; Elektriskframdrivning; BP-HiPIMS; Rymdframdrivningssystem;

    Sammanfattning : The ion acceleration process in Bipolar High Power Impulse Magnetron Sputteringis investigated for use in a novel space propulsion system - the BP-HiPIMS thruster.The interest for BP-HiPIMS has recently been growing within the area of thin filmdeposition due to the theorised acceleration of target ions caused by the reversedpulse following the regular HiPIMS pulse.

  7. 15. Intake Design, and Optimization for an Atmosphere- Breathing Electric Propulsion System

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesus Espinosa Orozco; [2020]
    Nyckelord :Atmospheric Intake; ABEP; Electric Propulsion; Plasma; VLEO;

    Sammanfattning : Over the last two decades, Very Low Earth Orbit (VLEO) has gained researchers attention as it provides a significant amount of benefits in the field of earth observation and telecommunications. VLEO provides increased payload performance, improved geospatial accuracy, lower launch mass, simplified end of life disposal, and they reduce space-debris collision risk. LÄS MER
