Mekaniskt och strukturellt koncept för mikrogravitationsexperimentet AtmoFlow på den Internationella rymdstationen (Swedish)
Abstract [en]

This Master Thesis report presents the mechanical concept and design of a microgravity fluid science experiment that is planned to be launched to the International Space Station in approximately five years. Named AtmoFlow, this experiment aims to study the complex flow phenomena occurring in different planets’ atmosphere by implementing a scaled-down model of a planet-atmosphere system in microgravity. The design introduced here focuses on several of the experiment’s systems: the Turn Table, a rotating system involving a Fluid Cell Assembly, a Thermal Control System and two Rotation Drive Systems. Design methods, main choices and crucial conception steps are presented. Components’ dimensioning and choices are motivated. Models and analyses are derived from the selected design to ensure that the design meets the requirements on microgravity disturbances, structural and rotational characteristics stated during previous project’s phases. The Computer Assisted Design model of the experiment’s final concept and its integration sequence are eventually proposed and discussed.

Abstract [sv]

Denna rapport presenterar den mekaniska utformningen av ett mikrogravitationsexperiment som studerar strömningsmekaniska fenomen och som planeras att skickas till den internationella rymdstationen om ungefär fem år. Experimentet heter AtmoFlow och syftar till att studera komplexa flödesfenomen som förekommer i olika planeters atmosfärer genom att implementera en nerskalad modell av en planets atmosfärssystem i mikrogravitation. Utformningen av experimentet som presenteras här fokuserar på flera av experimentets system: rotationsbordet (ett roterande system med en strömningscellhopsättning), ett termiskt reglersystem samt två rotationsdrivsystem. Utformningsmetoder, huvudsakliga val och utformningssteg presenteras. Dimensioneringen av komponenter och deras urval motiveras. Modeller och analyser av den valda konstruktionen har utförts för att säkerställa att den uppfyller kraven på störningar i mikrogravitation, struktur och rotationsegenskaper som specificerats under tidigare faser i utformningen av experimentet. CAD-modellen av den slutliga utformningen av konstruktionen av experimentet presenteras och diskuteras.
