Injector designers
Evaluate pattern, hole count, and diameter trade-offs quickly.
Injector sizing software
Rocket injector sizing software.
Size unlike doublets, triplets, and showerhead concepts with per-stream orifice sizing, pressure drop, momentum ratio, packing and ligament checks, and O/F consistency warnings — inside the same engine case used for sizing and geometry.
Mac 1.0.0 · signed and notarized. Windows 1.0.0 Public Beta · unsigned. Preliminary design software for analysis, iteration, documentation, and review.
Who it is for
For injector design and review.
Explore patterns and orifice geometry while keeping O/F and pressure-drop assumptions visible.
Test engineers
Review drill-chart outputs and pressure-drop context before fabrication.
Reviewers
See momentum ratio and O/F consistency warnings with the inputs.
Workflow
Injector sizing, with the assumptions shown.
Per-stream sizing tied to the solved O/F and chamber conditions.
Pattern selection
Unlike doublets, triplets, and showerhead concepts.
Orifice sizing
Per-stream diameters, hole counts, and drill-chart outputs.
Pressure and momentum
Pressure drop, momentum ratio, packing, and ligament checks.
O/F consistency
Warnings when stream sizing diverges from the target O/F.
