On the design and evaluation
of ducted propellers as pumps

• STG Potsdam '93 paper
  
• STG Potsdam '93 presentation
  
• KSRI St. Petersburg '94 paper
  
• KSRI St. Petersburg '94 presentation
  In the presentation the photographs
  of the propeller are still missing.
  
  See also the discussions of the papers by the
  Triantafyllou brothers concerning fish propulsion:
  
• Scientific American discussion '95
