China's first domestic EVA — Zhai Zhigang, Shenzhou VII 2008
Limited operational cadence; not a mature fleet product; imported Haiying suit flew alongside as backup
"Pragmatic dual-track approach — import to reduce mission risk while demonstrating domestic capability simultaneously"
Validates China's sovereign EVA technology transition path; Feitian Gen-1 is to China what BERKUT was to the Soviets
Unexpected arm growth when shoulder restraint cable failed; seized pulley caused overheating in crotch-thigh region
→ Critical restraint paths need redundancy or condition monitoring. Small mechanical hardware in pressure-load paths creates outsized crew risk
Suit inflation during Leonov's EVA made movement and airlock re-entry critically difficult — Leonov had to partially deflate to re-enter
→ Make ingress/egress and self-rescue a separate verification gate from EVA capability itself
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
"Rescue suit discipline must be kept separate from EVA product line — do not overbuild IVA with EVA objectives"
"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…"
