Abstract
A split flow injector for solid fuel ramjets (SFRJ) having a tube injected nto the injector port of a SFRJ to split the air into two streams wherein the primary airflow through the annular area around the tube is injected into the recirculation region just inside the injector port to stabilize combustion.
Claims5
In a solid fuel ramjet, having a casing with an injector port and a fuel port with a recirculation region adjacent to and downstream from said injector port, the improvement comprising:
- an inner tube situated centrally in said injector port and extending into said fuel port to divide an airflow through said injector port into a primary and secondary airstream, said primary airstream being injected into said recirculation region to stabilize combustion and said secondary airstream being injected into said fuel port downstream from said recirculation region to smooth said airflow.
