Evidence & editorial method

Let the evidence
carry the claim.

How this site distinguishes published results, mathematical models, proposed work and unsupported conclusions.

Four types of source record

  • Measured evidence: reported laboratory or flight observations. The context and scale remain part of the claim.
  • Theory & models: mathematical results, numerical predictions or proposed architectures. A simulation result is not an apparatus result.
  • Test & replication: disputed positive claims and null tests, with limitations shown together.
  • Methods & definitions: measurement practice, technical guidance and maturity definitions.

Company status

Metric Flight is a proposed research venture. Alpha 1 is a company hypothesis requiring a physical definition and test. No company thrust dataset, independent replication, vehicle prototype or measured propulsion performance is supplied for this edition.

Source method

The 41-record atlas was assembled by targeted searches of primary publications, author repositories and official institutional records. Each note links to the original work, summarizes its contribution and marks a limitation. This is a curated first edition, not an exhaustive systematic review. Some records were checked at abstract or repository level rather than by complete full-text analysis.

Publication dates follow the source. When early-online and journal-issue years differ, the record notes both where available. Undated institutional definitions are identified as reference material. Sources can be revised; consult corrections and current primary records before using a result in design.

Illustrations and calculations

All moving visuals in this edition are original code-based schematics. They are not test photography, live telemetry, actual apparatus or validated Alpha 1 simulations. Calculator assumptions and constants are stated beside the results. Reduced-motion settings are respected, and a pause control is available throughout.

AI assistance

AI assisted research discovery, synthesis, wording, coding and design. Primary records were used to check the source metadata and central claims. This process does not constitute independent peer review or experimental validation.

Corrections

Use the research-note builder to identify the page, the challenged statement, the original source and a proposed correction. Preserve both the correction and its reason in the next edition’s change record.
