Title:

NOZZLE FOR LIQUID ROCKET ENGINE

Document Type and Number:

Japanese Patent JP2012189010

Kind Code:

A

Abstract:

To solve such a problem that, in a conventional nozzle for a liquid rocket engine, the man-hour or cost of manufacturing is high for a nozzle requiring regeneration cooling or a nozzle using a heat-resistant metal such as columbium.

A nozzle N for a liquid rocket engine includes an annular manifold 1 on a circumference downstream from a throat T, the manifold making a cooling fluid introduced from the outside of the nozzle flow out along the nozzle inner face. By making the cooling fluid flow out of the annular manifold 1 along the nozzle inner face, film-cooling is carried out by the cooling fluid to maintain a sufficient heat-resistant function, and moreover, reduction in the man-hour of manufacturing or reduction in the cost of manufacturing is achieved.
