Abstract:

The first sub-scale nozzle for the 5,000 pound thrust motor was motor tested. This nozzle indicated excellent performance for the expansion cone, the insert back-up piece, and entrance back-up piece of castable carbon. The expansion cone erosion rate ranged from about 0.8 to 1.2 milssec this performance was reported to be superior to any other cone tested in the 5,000 pound thrust motor. Substantial erosion occurred, however, on the castable carbon entrance section. Design and material improvements are being sought especially for this area.
