Technische Universität München Microarchitecture Space Studies Project: E. NET METHODS AND MATERIALS: Subjects: © 1999 all copyrights of the shown projects are with the designers and the departement for design and architecture at tu münchen Summary Report Date: 12/06/1999 Page: E 02 The Net consists of the collecting device itself and a holder. The holder can take several adapters, for seattrack or clamps for handrails. The collecting device consists of three rings, one of them moveable. The closing mechanism consists of the springs which opens like a f-stop of a camera. It is opened with one hand against the force of a spring, which closes the device when released.. Two versions of the NET were tested: The larger version which fits the size of an ordinary trash bag. The smaller version which fits in one of the BOCS (Built-in-on-orbit-container-system) by Julia Habel The NET (with the exception of the trash-bag) is made from steel to withstand the forces of the parabolic flights. On-orbit versions should be made from aluminium or carbon-fibre. Procedure: The two versions of the NET were mounted on the rear side of a rack of the FLOW-experiment. The small version of the NET was also mounted on a belt . The Net on the belt was used to do simulated housekeeping. Different simulated trash was used to test the two versions. RESULTS: The NET worked fine in microgravity. During zero-G the NET sometimes needed some help to close completely. It was difficult to attach the NET to seat track during zero-G. The small NET on the belt could be used easily for housekeeping. DISCUSSION: The closing spring is not strong enough. The design of the attachment-point for seat track is not yet suitable for zero-G. The principle of the NET works in zero-G.
Technische Universität München Microarchitecture Space Studies Project: E. NET CONCLUSION: © 1999 all copyrights of the shown projects are with the designers and the departement for design and architecture at tu münchen Summary Report Date: 12/06/1999 Page: E 03 The force of the closing spring has to be reinforced. The attachment point to seat-track has to be improved, The NET works in zero-G and can be used to develop on-orbit versions. Further testing to verify improvements are necessary. REFERENCES:
