Abstract:

A high performance Ir-Re 14 1bf 62 N chamber and nozzle which can be a direct replacement for a production engine was designed, built, hot fired and vibration acceptance tested. It passed all acceptance tests satisfactorily and demonstrated a 20 sec increase in Is over the conventional 14 1bf silicide coated Cb chamber. The high performance engine uses the production valve and injector without modification. Incorporation of a secondary mixing device or Boundary Layer Trip within the combustion chamber results in elimination of the fuel film coolant, improvement in flow uniformity, the 20 sec performance increase, and reduction of a potential source of spacecraft contamination. Measured specific impulse Is was 305 sec at 751 area ratio, with monomethylhydrazine and nitrogen tetroxide propellants. Qualification tests remain to be done....
