Principles of Multi-Channel Redundancy of an Interuniversal Spacecraft: Electronics, Hydraulics, and Mechanics as Independent Control and Life Support Systems

This article presents the concept of multi‑channel redundancy for the interuniversal spacecraft MPC‑1 Wanderlust, developed within the framework of the Infinite‑Dimensional Multiverse Model (IDM). The key design principle is that control and life support systems are built on three independent physical principles: electrical (electronics), hydraulic (fluid pressure), and mechanical (physical force, cables, levers, springs, flywheels). This makes them independent of each other and ensures crew survival in the event of failure of any one or two redundancy levels. The article describes in detail the main modules of the spacecraft, primary systems with redundancy, as well as two fully autonomous backup control systems — hydraulic and mechanical, independent of electronics. Equipment and domestic systems are considered, including safe lighting, food heating (using alternative chemical reactions that do not require oxygen), ventilation, and oxygen generation on three different principles (electrochemistry, chemistry, mechanics). The survival kit "Earth Biosphere‑1" is introduced — a large inflatable structure with an artificial biocenosis, ensuring autonomous crew existence for up to 3 years in emergency isolation. Testing protocols for spacecraft control and support systems, repair procedures for critical systems, and a comprehensive test of the emergency alarm systems "Golos" (DVBIR, KSVIP, AVZR) are presented. Return to U_0 and quarantine procedures are described. No direct analogues of this three‑level redundancy concept based on different physical principles with the addition of a biological survival level have been found in the open literature. This makes the proposed concept original and promising for further engineering development.
