  1. 1. Improved Release Mechanisms for Aerospace Applications

    Kandidat-uppsats, Uppsala universitet/Tillämpad mekanik

    Författare :Baran Hamad; Markus Englund; [2021]
    Nyckelord :release mechanisms; hdrm; split spool initiator; reusable; smart materials; shape memory alloy; sma; pyrotechnic; non-explosive; spacecraft; nitinol; releasemekanismer; hdrm; fästelement; split spool-initierare; återanvändbar; minnesmetall; pyrotekniska; icke-explosiva; rymdfarkost; nitinol;

    Sammanfattning : Hold down release mechanisms (HDRMs) are used for tightly attaching segments of bodies together when it is desired to release them rapidly at some point. When transporting sensitive payloads on launch vehicles, the challenge arises of releasing the fastened segments of the spacecraft without risking damage to the costly equipment. LÄS MER

  3. 2. Emulation of Recoil in Pyrotechnic Countermeasure Dispenser System

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Ebba Lindgren; [2020]
    Nyckelord :Countermeasures; Flares; Recoil; Optimization; Pyroshock Testing; Motmedelssystem; Facklor; Rekylkraft; Optimering; Pyroshocktestning;

    Sammanfattning : Developing countermeasures dispenser systems requires many and careful tests. When it comes to testing products with pyrotechnics, testing can often be very complicated and expensive. This might lead to no testing at all due to time or resource shortages. LÄS MER

  4. 3. Assessment of thermal radiation arithmetic's for jet flames : A study involving generic calculation methods concerning radiation from jet flames with the purpose to determine the safety distance for flame effects

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anne Lee Anderson; [2018]
    Nyckelord :Jet flame; view factor; incident radiation; radiation temperature; safety distance;

    Sammanfattning : Jet flames are commonly used as flame effects in pyrotechnical shows, and are also a possible risk in industries that uses pressurised flammable gas. For these users it is important to  make fire safety engineering calculations to minimise the risks. This project focus on jet flames that are used in pyrotechnic shows where, e.g. LÄS MER
