ABSTRACT:
A self-propelled torpedo with four stabilizer fins having an "X" orientat when the torpedo is running submerged through water. Each stabilizer fin has a fixed leading section and a trailing rudder section with a rigid trailing edge. Bands of tape are wrapped fore and aft around each rudder section to provide opposed trailing extensions of tape which are adhered together and slitted to form a trailing extension of flexible material with separate strips along the full length of the rigid trailing edge. The trailing extension of flexible material provides for shedding trailing edge vortexes downstream for reducing the transmission of vortex energy upstream to the rudder.
