Phase A Design of an Innovative Greenhouse Chamber for Utilisation in a Planetary Research Base

Abstract [en]

The DLR Greenhouse Chamber is the first step by the Deutsches Zentrum für Luft- und Raumfahrt (DLR) into the creation of a Closed Environment Life Support System (CELSS) to support future manned planetary space missions. The focus of this thesis has been on the Phase A mechanical design of the DLR Greenhouse Chamber. A detailed trade study into a wide variety of potential module configurations was conducted and from this study, a series of four module configurations are proposed which are suitable for utilisation in a planetary space mission. These modules are the Fully Rigid Cylindrical Module, the Inflatable Concertina Style Module, the Semi-Rigid, Octagonal Based Module with Rigid Floor, Roof, and Two Side Walls, and the Semi-Rigid, Octagonal Based Module with Two Levels. Each of these proposed modules offers unique characteristics and as such, the final selection of the module configuration will depend on the specific requirements of the planetary mission.The aeroponic growing systems required for the DLR Greenhouse Chamber are identified, explored and modelled in detail, as are the mechanical subsystems of the chamber. A wide variety of plants have been catered for in the designs of the grow units including standard crops, dwarf trees, perennial plants, and herbs. Each system and subsystem is designed to offer as wide a range of customisable features as possible, in order to provide optimal growing conditions for the plants and to maximise the potential yield produced by the chamber.The module configurations and systems designed during this thesis were evaluated for their suitability to supply a manned space mission with positive results. The future direction of the project was also discussed, with the future work still to be completed outlined.
