- Worth noticing
- The homepage shows three verification counts—127, 62, and 35—so its test-status claims are internally inconsistent.
Field notes
The input panel spans propellant selection, injector geometry, cooling-jacket dimensions, nozzle settings, and engine power cycles. A sample output includes chamber dimensions and flow figures, while the CAD controls offer multiple views, material selections, and STEP/STL-related exports. The page also advertises engine presets and validation against NASA or literature, but those accuracy claims are not independently established here.
