Abstract
An exhaust dissipator device for a rocket exhaust has an inlet for connection to the exhaust and a plurality of smaller exhaust orifices spaced around its surface to dissipate the flow into a plurality of smaller jets. A deflector surface in the direction of exhaust flow into the container acts to further dissipate the flow and deflect it out of its original path. This may comprise an internal surface of the container, or a separate deflector plate spaced from the container surface.
Claims7
An exhaust dissipator device for connection to a rocket exhaust, comprising:
- a container of elongate shape having a unique central longitudinal axis and defining an enclosed chamber having an inlet at an intermediate point in the length of the container for connection to a rocket exhaust to direct rocket exhaust flow into the container in a direction transverse to the central longitudinal axis of the container and a plurality of exhaust orifices spaced around the container for exhaust flow out of the container;
- each orifice comprising a tapered nozzle of area increasing outwardly from the interior of the container;
- and
- a solid deflector surface in said container in the direction of exhaust flow into the container for deflecting flow in a direction generally normal to the original exhast flow direction.
An exhaust dissipator device for a rocket exhaust, comprising:
- a cylindrical container defining an enclosed volume having an inlet for connection to a rocket exhaust and a plurality of exhaust orifices of smaller dimensions than the inlet spaced around and along the length of the container for exhaust flow out of the container in a plurality of different directions;
- the container having said inlet at an intermediate point in its length to direct rocket exhaust flow into said container in a radial direction generally transverse to the longitudinal axis of said container;
- and
- a solid deflector surface in said container wall opposite said inlet for deflecting exhaust flow out of its inlet direction and towards the opposite axial ends of said container.
