POTENTIAL FLOW SOLUTION OF PROPELLER DRIVEN JETS USED FOR SUBMARINE DEPTH CONTROL,

Abstract

A two-dimensional potential flow analysis is performed of a submarine hull fitted with two symmetrically placed vertical open end tubes each containing a propeller. It is found that the thrust obtained is always less than the full jet momentum which would have been obtained had one end of the tube been closed. This occurs because the propeller must work to move the external fluid. The thrust is found to depend on tube location, and can be maximized by placing the tubes near the center of the hull, in which case two thirds of the full jet momentum is achieved. (Author)
