Abstract
Disclosed is a multiple start torpedo including an aft body having an exhaust conduit defining a turbine end and a seawater end having an orifice. The multiple start torpedo includes an exhaust valve associated with the exhaust conduit including. The exhaust valve includes a fore section having a head and a valve stem. The exhaust valve includes an aft section tapered from the turbine end to the seawater end and defining a receptacle sized to receive the valve stem. The exhaust valve includes a biasing member disposed to bias the head in an extended position spaced apart from the aft section and abut the orifice in the extended position.
Claims20
A multiple start torpedo comprising:
- an aft body having an exhaust conduit defining a turbine end and a seawater end having an orifice;
- and
- an exhaust valve associated with the exhaust conduit including:
- a fore section having a head and a valve stem;
- an aft section tapered from the turbine end to the seawater end and defining a receptacle sized to receive the valve stem;
- and
- a biasing member disposed to bias the head in an extended position spaced apart from the aft section and abut the orifice in the extended position.
A multiple start torpedo comprising:
- an exhaust valve including
- a fore section having a head and a valve stem,
- an aft section and defining a receptacle sized to receive the valve stem, and
- a biasing member having an extended position where the head is spaced apart from the aft section and a compressed position where the head and the aft section form a teardrop shape.
A multiple start torpedo comprising:
- an exhaust valve including:
- a fore section including a head defining a maximum outer diameter and a valve stem;
- an aft section and defining a receptacle sized to receive the valve stem;
- and
- a biasing member having an extended position where the head is spaced apart from the aft section and a compressed position where the head and the aft section form an inner teardrop shape having an inner bulbous portion and an inner tail portion;
- and
- an exhaust conduit defining a seawater end and a turbine end, including an orifice defining an orifice diameter less than the maximum outer diameter such that the head is sized to block the orifice in the extended position, and including a contour having an outer teardrop shape that mimics the inner teardrop shape having an outer bulbous portion that joins the orifice toward the turbine end and an outer tail portion that extends toward the seawater end.
