This represents my inaugural endeavor in fabricating a steel nozzle using stock material and lathe equipment. Currently without specific applications, hydrostatic testing could provide valuable insights.

Nozzle Design Specifications

  • 45° half-angle convergent section
  • 30° half-angle transition
  • Approximately 0.2" throat diameter
  • 45° half-angle divergent section

Construction Notes

The design prioritizes experimentation rather than optimization, with no strict dimensional specifications. Equipment utilized included vintage machinery (approximately 60-year-old lathe with modified cutting edges and worn drill bits).

Future Plans

I intend to develop formal schematics and source smaller materials compatible with current rocket motor experiments to evaluate potential nozzle-based performance improvements.
