I spent most of last quarter crawling through the secondary heat exchanger on Deck 4, chasing a 0.3% efficiency drop that ops insisted didn't matter. They were wrong. At sustained 0.8G, a thermal gradient of four degrees across the reaction chamber housing compounds into a full containment flutter within 90 hours. We caught it on hour 87.
The flutter threshold nobody specs for
The manufacturer — I will not name them, but they ship out of Callisto — rates the TX-440 core for 12,000 hours between overhauls. That number assumes steady-state at 0.3G or below. Nobody in the Belt runs that profile. Across three ships, our average was 0.6G sustained, and two of those three hit containment flutter before the 8,000-hour mark.
The manual is a best-case scenario written by someone who never signed off on a hot restart at 02:00 with half the crew in crash couches.
