Shenzhou launch, entry and cabin depressurization survival
Not EVA-capable; long-duration seated comfort secondary to emergency survival; donning speed under study
"Rescue suit discipline must be kept separate from EVA product line — do not overbuild IVA with EVA objectives"
Relevant to any commercial crew vehicle requiring low-mass cabin-supported rescue architecture
Water entered Luca Parmitano's helmet during EVA — vision impaired, comms degraded, breathing compromised
→ Cooling-water management is a primary safety-critical function, not a nuisance issue. Contamination tolerance must be designed in from day one
Risk that Feitian Gen-2 orbital EVA success may drive incremental adaptation to lunar surface rather than treating Wangyu as a new architecture branch
→ Orbital EVA success is not a sufficient baseline for lunar surface operations — treat as a new product architecture, not an upgrade
Suit lifespan initially limited to 15 EVAs over 3 years; exceeded in operations before upgrade to 20 EVAs/4 years D/E series
→ Track cost-per-EVA, turnaround time and anomaly-free hours as primary KPIs once a suit enters fleet operations
"Pragmatic dual-track approach — import to reduce mission risk while demonstrating domestic capability simultaneously"
"Once a suit becomes a fleet asset, lifecycle economics and telemetry matter more than peak performance figures"
"Lunar suit must be treated as a new architecture branch — not an incremental Feitian derivative — due to dust, terrain and thermal differenc…"
