This repository is intended to be credible to aerospace engineers. That means:
- Claims must be physically plausible under known conservation laws.
- Claims must be traceable to evidence, models, or measurements.
- Speculation is allowed only when clearly labeled and bounded.
Allowed when supported by at least a toy model + stated assumptions:
- Momentum exchange via propellant, atmosphere, photons, or field-coupled external media (solar wind / ionosphere / magnetosphere).
- Aerocapture/aerobraking/EDL corridor control concepts.
- Deployables (HIAD/ballute/aeroshell) as drag/BC modifiers.
- Thermal protection and structural survivability strategies.
- Sensing/telemetry architectures and verification logic.
Allowed when expressed as interfaces and invariants:
- "Module X consumes inputs Y and emits outputs Z"
- "SafetyGate prevents unsafe commands under constraint set C"
- "Telemetry provides reproducible replay and pass/fail evidence"
Allowed only when labeled HYPOTHESIS and accompanied by:
- What it would take to falsify it (kill criteria),
- Measurement plan,
- Expected magnitude ranges (even if broad),
- And a clear statement that it is NOT flight-validated.
The following are not allowed as dependencies for success in this repo:
- Reactionless thrust / propellantless net translation (closed-system momentum violation).
- Negative-energy requirements as an assumed engineering input.
- Warp-drive / inertial-damper functionality presented as buildable with 2026 hardware.
- "Zero-point extraction" or similar claims as a power source requirement.
- Any claim implying "instant stop" without external momentum exchange.
You may discuss these ideas only as:
- historical context,
- science-fiction inspiration,
- or "why this is not assumed" in a sanity-check section.
Use one of these tags in docs and models when making claims:
- E0 — Concept: qualitative idea only.
- E1 — Toy model: back-of-envelope math, stated assumptions, order-of-magnitude check.
- E2 — Implemented model: code runs, units checked, produces repeatable outputs.
- E3 — Cross-checked: matches published ranges or independent sim within stated tolerance.
- E4 — Measured: hardware or bench test data exists with documented uncertainty.
- E5 — Flight relevant: validated against flight or flight-like test conditions.
If a section contains any claim stronger than E1, it must link to:
- the model producing the result, and
- the assumptions used.
- All equations must define variables and units.
- All numeric constants must have provenance (citation or derivation).
- Every plot/table must reference the config that produced it.
- All "wins" must name a baseline for comparison.
This repo is about deceleration architectures for aerospace vehicles and scientific simulation. We do not include instructions to build harmful devices or weaponizable systems. If a concept overlaps with dual-use, it must be treated at high level and framed for safety, validation, and benign applications only.
