Technische Universität München Microarchitecture Space Studies Project: A. FLOW Results, Discussion: © 1999 all copyrights of the shown projects are with the designers and the departement for design and architecture at tu münchen Postflight Report Date: 12/06/1999 Page: A 04 The flights prove our results from the underwater tests; the restraining principle does work. We got some insights into the problems users might have with the restraining mechanisms and discussed possible solutions. Despite the model unique adjustment difficulties (caused by the extreme mass and construction solutions that we had to choose to match the KC-135 safety criteria) the adjustment system and procedure prove to be viable. The flight hardware concept model B showed that the handling of the system in micro-g is no problem. We just found that the interface concept needs more work. Of course the whole engineering is still in the concept phase. Conclusion: We think that the system of the flow table is a solution for several important problems of living in a micro-g environment. The flight campaign prove the quality of the concept and we could verify our basic assumptions. Advancing from this, it is possible to develop actual flight hardware.

The flow system consists of the workstation module and various interface to attach it to a seat track and to<br />
form a wardroom table configuration. Subject of this parabolic-flight campaign was just the module: the restraining<br />
principle, the geometry of the construction and additional design issues.<br />
To test a workstation model in the KC-135 parabolic-flight environment the construction had either to be<br />
braced or extremely tough. We chose the latter option of a free swinging construction for the parabolic flight<br />
test model A, because it is relatively close to an on-orbit configuration and the in-flight adjusting effort could<br />
be reduced.<br />
Another design test model B was constructed to try out the look and feel.<br />
Both models were attached to stands that were mounted on the floor of the plane. All interfaces were just<br />
functional mock-ups.<br />
Procedure:<br />
There are detailed test procedures. This is just a summary of the subject headers of repeated test actions:<br />
Day 1<br />

Quick test of adjustment<br />
Fine tuning model a<br />
Test of restraining modes<br />
Test of wrong adjustments model a<br />
Handling model b free floating<br />
Test model a by inexperienced user<br />

Perform tasks on model b (restrained in foot loops)<br />
Day 2<br />
Same as day 1 plus:<br />
Test bungees on model b restrained in foot loops<br />
Perform tasks on model a<br />
Perform tasks on model b (compare)
