MAIN PROPULSION (FOILBORNE)

propulsion is created by a two-stage water jet pump

SYSTEM

occurs as seawater is pumped through the water jets and

The foilborne propulsion system provides the PHM

resulting from the acceleration and expulsion of the

foilborne propulsion system are shown in figure 7-20.

The foilborne power plant supplies the thrust required

seawater drives the ship forward. The main advantage

for takeoff and foilborne operations. Foilborne
