The work so far
Resonance is in design review. Nothing has been built or fired yet. Each entry is a dated review or design change, including the ones that found problems.
Trade-study audit
Recomputed the 134-slide trade study against the design record and primary papers. Found six critical items to close before a design review, led by the coolant cross-section and the thermal design load.
Trade-study baseline
A 134-slide study of the injector, cooling, joints, ignition, feed and diagnostics. Kept as a working notebook, not a frozen design.
System requirements review
Kept the programme intent. Rejected a 100–110 mm channel as outside published methane data and set the channel at 85 by 5 mm.
Design record r3
Moved the mixture ratio from 3.25 to 3.00. The old value leaned on gaseous-propellant engines; the liquid-propellant chemistry peaks at 2.945.
Independent design review
Every design record checked and the thermochemistry re-run. Verdict: a physically plausible research concept, not yet ready for hardware release.
