    Abstract : The space industry and the technological developments regarding space exploration hasn’t been this popular since the first moon landing. The privatization of space exploration and the vertical landing rockets made rocket science mainstream again. READ MORE

  3. 2. Optical System for Impact Determination of Sounding Rockets

    University essay from KTH/Rymdteknik

    Author : Fredrik Haider; [2020]
    Keywords : ;

    Abstract : To be able to ensure range safety and quickly recover the rocket and any on-board experiment, it is essential to be able to track the rocket. For sounding rocket launches at Esrange, this is typically done with radar or rocket telemetry, it has, however, recentlybecome of interest to do so with an optical system. READ MORE

  4. 3. Propellant Feeding System of a Liquid Rocket With Multiple Engines

    University essay from KTH/Rymdteknik

    Author : Valentin Miquel; [2020]
    Keywords : Multiengine Feeding System;

    Abstract : Multiengine first stages are the new trend in recent rockets. Reusability and an oxygen/methane based engine complete this picture. ArianeGroup wants to develop its own rocket following these principles. This thesis presents the study of the feeding system for a seven Prometheus engine rocket. READ MORE
