Abstract
A linear capillary orifice injector for producing a chemical reaction in a combustion chamber is disclosed. The orifices are judiciously arranged to form a discrete pattern for achieving a high degree of shear mixing while attaining a uniform temperature and species profile particularly necessary for chemical lasers.
Claims8
An injector for a combustion chamber for injecting fuel and oxidizer into said combustion chamber where combustion ensues, said injector comprising a block-like element having wall means defining a face in said combustion chamber, a plurality of spaced vertically stacked capillary tubes disposed in a slot in said block-like element, which slot extends rearwardly from a point short of the face of said wall means, said capillary tubes terminating in said face and defining an array of orifices disposed in a given pattern which pattern includes two columns of parallel spaced orifices for injecting an oxidizer and a single column of orifices spaced equidistance from two adjacent parallel orifices for injecting fuel, said capillary tubes being sized so that frictional pressure drop regulates the flow therethrough, and separate fuel and oxidizer manifold means in said block-like element for communicating with an end remote from said orifices of each of said capillary tubes.
