Re: Water Jets

[SFreihof@aol.com]

Using water jets for propulsion and attitude control is not new.  Cousteau 
used this technique on his diving saucers.  His mini-subs had a water pump, 
diverter valve, and two independently rotatable nozzles.  With this 
arrangement he could go up, down, left, right, forward, backwards, and spin 
on its own axis.  On the surface, he would point them straight up and shoot 
water into the air like a fountain to make the sub easier to find by his 
surface support teams.

 I'm thinking it might be feasible to have a sub propelled by a water jet, 
 and maneuvered by smaller jets pushing in different directions.  Maybe using 
 pressure washer pumps?  It would make a sub a lot more streamlined without 
 any motors hanging outside!  Can anyone think of any pros and cons to this 
 idea?
