Abstract
A submersible projectile includes an elongate body. The elongate body has an axial forward end and an axial rearward end and a peripheral surface. The elongate body has a generally elliptical cross-section along substantially all of the axial length of the elongate body. A plurality of fins project from the elongate body near the axial rearward end of the body wherein the fins are spaced about the peripheral surface.
Claims13
A submersible projectile comprising:
- an elongate body having an axial forward end and an axial rearward end and a peripheral surface, and the elongate body has a central longitudinal axis;
- the elongate body having a generally elliptical cross-section along substantially all of the axial length of the elongate body;
- a plurality of fins projecting from the elongate body near the axial rearward end of the body, and the fins being spaced about the peripheral surface;
- and
- wherein one of the plurality of fins is an upper radial fin that has a generally vertical orientation, and the upper radial fin projects in a radial fashion away from the elongate body, and the plurality of fins further includes a plurality of lower non-radial fins that are not aligned to the central longitudinal axis of the elongate body.
