ACKNOWLEDGMENTS 

 The author is indebted to many members of the staff at the David W. Taylor Naval 

 Ship Research and Development Center. Without the combined effort of these individ-

 Ben Wisler for maintaining the 1000 hp dynamometer and the blade pressure measurement 

 systems, to Mike Jeffers for developing and maintaining the computer data collection 

 and analysis procedures, to John Webb for maintaining the pressure gage electronics, 

 to Douglas Dahmer for assisting with test procedures, and data reduction, and to 

 Dona Nigro for much of the final data reduction and plotting. Special thanks go to 

 Robert Boswell for his guidance and support provided during all stages of the 

 experiments.
