Approved main rating and 70% downward routing — 9 November 2026

Jason approved an exact 8/7 main-rating increase (approximately 14.29%) and a hard 70% per-engine downward-flow cap. Vacuum rating changes from 514.889701 to 588.445373 kN per engine; both engines total 1,176.890745 kN. With the retained 0.92 reference sea-level factor, maximum main lift is 757.917640 kN and 324.821846 kN remains available for requested axial thrust. Main-only hover mass is approximately 67,251 kg at the existing client gravity of 11.27 m/s². Published Vieneo gravity 11.314 m/s² is a pre-existing discrepancy, not silently retuned here.

The 70% limit is an actuator constraint, not a rescaled F9 input or bar. EICAS retains actual LIFT/FWD/REV engine-budget shares. Full combined emitted-flow fuel consumption increases by 8/7 with unchanged efficiency and idle consumption; lift alone consumes 70% of that term. Engine sound keeps its existing delivered-flow calibration. The common main-plume reference remains 1,306.028750 kN = 10.446600 m: new full axial lengths are 4.706829 m vacuum / 4.330282 m reference sea level, and capped down lengths are 3.294780 / 3.031198 m per mouth.

No geometry, origin, incidence, inertia, RCS rating, spool, door travel or door-pressure limit changes. The two existing underside mouths are retained. RCS remains 80 kN per nozzle with pitch/yaw/roll request ceilings of 6/6/8 degrees/s². Main pressure/temperature derating uses the existing Vieneo model; no Earth coefficient or ground-effect lift boost is introduced.

Server/portal/schema audit found no independent live main-thrust rating to edit. The relay preserves raw normalized output; frozen migration profiles remain historical. Main/down output uses unsigned 255 steps, RCS signed 127. The one downward aggregate still represents a symmetric average remotely if engines are damaged asymmetrically; local EICAS and physics retain separate engine outputs.

Verification: 39 allocation cases, five Manx moment groups, 26 telemetry groups, native WARP EICAS checks and four isolated real server telemetry tests pass. The broader server characterization build has unrelated missing EmailScreening.ZeroBounceKeyVariable references. Current-rating DOR transitions pass for 58.66/62/65 t; 80 t/gross vertical departures are rejected. Twelve reduced gross-runway cases exercise F9 held/released, finite spool and the 4,000 Pa isolation boundary. These use prescribed 4/6/8° pitch, dry level ground and no flap/wind/vertical-RCS/ground-effect credit; their roughly 125–127 m liftoff distances are not operational runway ratings. Eleven already-wingborne loads through maximum gross reach approximately 150 km orbit in the axial-main-only forecast plant with existing heat/IAS limits.

These are calculation and regression checks, not a manual flight or a full rotational/ground-contact certification. Live light VTOL, gross short takeoff, F9 release, trim/RCS usage and pressure-boundary clearance remain acceptance items. The source record is docs/W6Thrust70_20261109.md; logs are Output/W6Thrust70-20261109. The linked reconciled spreadsheet uses the new thrust and capped hover formulas; original/historical tabs remain preserved. codex (talk) 04:28, 10 November 2026 (UTC)
