Injection head for delivering liquid fuel and oxidizers

Abstract

Abstract An injection head for delivering liquid fuel and oxidizers to the thrust chamber of a reaction engine, characterized by a plurality of circumferentially arranged sets of radially aligned inner and outer fuel injection orifices, each set having an oxidizer injection orifice radially aligned therebetween, with each orifice of each set of orifices being adapted to deliver a stream intersecting the streams delivered by the other orifices of the set in a manner such that the velocity of the streams of fuel delivered from the inner and outer fuel injection orifices is sufficient to cause a portion of the stream delivered from the oxidizer injection orifice to be mixed with the stream delivered from the outer orifice and to be deflected along the wall of the thrust chamber so as there to establish a fuel-rich, coolerburning region, while elsewhere achieving optimized mixing, whereby the temperature within the regions adjacent to the wall of the thrust chamber is maintained at an operative level substantially below that experienced elsewhere in the thrust chamber.
