Engineering workflow

## From requirements to public evidence

01

### Architecture

Orbit assembly, electric propulsion, counter-rotating habitats, visible power and heat-rejection systems.

02

### NX design

Master skeleton, expressions, WAVE-linked components, arrangements, interfaces, drawings and manufacturable demonstrators.

03

### ANSYS workflow

Static, modal, buckling, thermal and CFD case preparation with convergence and correlation records.

04

### Iteration

Screening exposed braking and docking flexibility; the H3 redesign added credible load paths and improved performance.

05

### Manufacturing

Representative milling and turning processes, tools, fixtures, setup sheets, inspection plans and printable prototypes.

06

### Open release

Neutral formats, reproducible scripts, traceability, claim boundaries and GitHub Pages presentation.

Engineering boundary

## Conceptual, transparent and intentionally non-fictional.

ASTERION is not a certified spacecraft, production aircraft, reactionless propulsion system or unrestricted-travel claim. Numerical results are reduced-order screening unless supported by owner-generated native NX/ANSYS evidence.
