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.

Native Apple silicon Mac. 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.

Injector designers

Evaluate pattern, hole count, and diameter trade-offs quickly.

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.
