Abstract : The report is descriptive in nature. For specifics of the technical accomplishment achieved under these grants, the reader is referred to the four theses by Potter, Rudy, Egolf and Pepin listed in the references. The first three of these theses have been completed and were prepared in partial fulfillment of the requirements for the Master of Science degree. Pepin's thesis is a Ph.D. dissertation which could not be completed before the expiration of the grant. It is currently being written and should be available shortly. All of these studies are generally related to helicopter applications although the specific motivation for their undertaking was initially the heavy-lift helicopter. The remainder of this report summarizes the findings of these investigators. (Modified author abstract)
