Mobile Fire-Safe Positioning System for the Protective Enclosure of a Robotic Propeller Restoration Complex.

Technical Note: Mobile Fire-Safe Positioning System for the Protective Enclosure of a Robotic Propeller Restoration Complex This technical note defines the design and deployment requirements for a mobile, fire-safe isolation enclosure for a Robotic Manufacturing System (RMS). The system performs supersonic cold gas-dynamic spraying (SCGDS) and finish grinding of marine propulsion components in open dry docks. Key Technical Solutions: • Magnetic Anchor Plates: Switchable neodymium (NdFeB) grippers eliminate welding and hot work on the ship's hull. • Silicone Interface Pad: High-strength siloxane elastomer pads (0.5–1.2 mm) increase friction by 2.5–3 times to resist wind loads, protect paintwork, and resist heat up to +200 °C. • Enclosure Frame: A tensioned steel/aramid rope framework with a non-combustible silica fabric tent, completely excluding flammable polymers. The document includes full component specifications and physico-mechanical substantiation.
