  1. 1. Improving thermal fracture resistance in ceramic microcomponents for spacecraft propulsion

    University essay from Uppsala universitet/Ångström Space Technology Centre (ÅSTC)

    Author : Erika Åkerfeldt; [2018]
    Keywords : HTCC; MEMS; MST; microthruster; thermal fracture;

    Abstract : Because of thermal transients and gradients occurring upon rapid heating or cooling, microcomponents made from High-Temperature Co-fired Ceramics (HTCC) often fail at temperatures far below what the materials can withstand per se. This work investigates how resistance to thermal fracture in HTCC microcomponents can be increased by improving the component design, aiming at increasing the thermal performance of a microthruster with integrated heaters.

  3. 2. Schlieren imaging of microrocket jets

    University essay from Rymdtekniskt centrum

    Author : Ville Lekholm; [2009]
    Keywords : Schlieren imaging; schlieren photography; microthruster; microexhaust; microrocket;

    Abstract : In this report, microrockets from the company NanoSpace were studied using schlieren imaging techniques. The rocket chips are manufactured using MEMS technology, which requires compromises regarding the shape of the nozzle. The rocket chips are 22x22x0.85 mm, manufactured from laminated silicon.
