Abstract
An apparatus for controlling fluid pressure recovery includes an elongated housing having an opening at a first end thereof, an opening at a second end thereof, an inner peripheral surface, and a fluid flow passageway therethrough. The apparatus further includes a plurality of choke members fixed to the inner peripheral surface of the housing, each of the plurality of choke members being spaced from an adjacent choke member and projecting a predetermined distance into the fluid flow passageway of the longitudinal housing. The plurality of choke members sequentially produce a reduced turbulent free shear fluid layer from the first end to the second end of the elongated housing.
Claims22
A pressure control apparatus for a submarine launchway comprising:
- a shutterway for enabling an entrance of fluid into the launchway, said shutterway having a first end and a second end;
- a control portion for serially reducing fluid momentum of a main core flow from said shutterway, said control portion having a first end thereof adjacent the second end of said shutterway and a second end opposite the first end;
- a launch tube aligned with said control portion and spaced from the second end of said control portion;
- and
- a free flood region surrounding said shutterway and said control portion, said free flood region exhausting fluid flow from said device.
A fluid pressure control apparatus comprising:
- an elongated housing having an opening at a first end thereof, an opening at a second end thereof, an inner peripheral surface and a fluid flow passageway therethrough;
- and
- a plurality of choke members fixed to the inner peripheral surface of said housing, each said plurality of choke members being spaced from an adjacent choke member and projecting into the fluid flow passageway of said longitudinal housing for interrupting at least a portion of the fluid flow therethrough;
- said plurality of choke members sequentially produce a reduced turbulent free shear fluid layer within said elongated housing.
A fluid pressure control apparatus comprising:
- an elongated housing having an opening at a first end thereof, an opening at a second end thereof, an inner peripheral surface and a fluid flow passageway therethrough;
- a plurality of choke members fixed to the inner peripheral surface of said housing, each said plurality of choke members being spaced from an adjacent choke member and projecting into the fluid flow passageway of said longitudinal housing for interrupting at least a portion of the fluid flow therethrough and serially reducing fluid momentum of a flow in the fluid flow passageway;
- and
- at least one longitudinal rib member connecting said plurality of choke members, said at least one longitudinal rib member and said plurality of choke members being formed of a one-piece construction.
