Engineering module
Vacuum Engineering
Closed-form or FEM estimates without a specific design code claim. Applies recommended default units when you change standard; unit dropdowns stay fully editable.
Design workflow
Design / Check / Select for Vacuum Engineering
Define targets in the inputs column, compare candidates in Select mode, and apply a sizing result before running a detailed check.
Use the Workflow mode control in the inputs column to switch between Check, Design, and Select.
Verify the geometry and loads already entered in the calculator.
Pump speed sweep against chamber volume and pressure ratio using vacuum solver.
| Option | Size | Util. | Margin | Status | Governing | Detail |
|---|---|---|---|---|---|---|
| Turbopump 500 L/s | Turbopump 500 L/s | 0.00 | 65144172285.49 | pass | design target | 0.0 min pump-down |
| Turbopump 250 L/s | Turbopump 250 L/s | 0.00 | 32572086142.74 | pass | design target | 0.0 min pump-down |
| Turbopump 80 L/s | Turbopump 80 L/s | 0.00 | 10423067565.68 | pass | design target | 0.0 min pump-down |
| Scroll 20 m³/h | Scroll 20 m³/h | 0.00 | 723824136.51 | pass | design target | 0.0 min pump-down |
Recommendation: Turbopump 500 L/s is the first passing candidate with design target governing.
- Computed from live calculator inputs via module design registry.
- utilization = demand / capacity (module-specific)
| Candidate | Basis | Pass criteria | Tradeoff |
|---|---|---|---|
| Research screen | Fast estimate | Flag risks | Lowest detail |
| Preliminary design | Balanced assumptions | Pass expected | Needs verification |
| Conservative design | Margin-first | High reserve | Heavier/costlier |
Candidate columns to calculate: Configuration, Margin, Risk, Next linked check.
- Cryogenic properties
- Vacuum conductance
- Magnet constants
- Battery/hydrogen safety references
- Pump speed classes
- Outgassing references
- Flange/window load references
- Advanced systems need assumptions shown prominently because coupled physics can dominate simple checks.
