Conclusions


Presently the human in the loop is required due to the new nature of the CCSB approach. Test engineers have to decide on the fly whether the flow meets the design criteria of the experimental setup. However, the DeAS windtunnel data acquisition and control system is prepared to accept parameter control from virtual devices. Thus, once the selection criteria may be expressed algorithmically or by some sort of an expert system, optimization of flow parameters in such complex experimental settings may well become an automatic process. Today the complexity of the experiment suggests a permanent human interaction. Due to the convenient windtunnel control system as well as the fast and elaborate data processing system decisions are available at a similar time as needed to adjust the windtunnel to a new set of flow parameters. Thus the experiment is not slowed down by human interaction. On the other hand the run-time data evaluation ensures a fast approach to the design point, avoids many unnecessary tests, and provides a valuable, advanced check for errors in an early phase of the experiment.
