An Autonomous Hyperbaric Chamber, Or a Hyperloop Tubular Railway Capsule

Abstract The authors conducted a comparative analysis of a high-speed transportation system—commonly referred to as the Hyperloop tubular railway—and a hyperbaric chamber as well as an aircraft cabin, with respect to differential pressure magnitudes and the associated technical and medical hazards that significantly affect passenger safety. The study examined fundamental systems and technical solutions governing pressure modulation, the composition of breathable air, the airflow required for capsule propulsion, and passenger protection. The analysis demonstrated the functional independence of these subsystems, confirming the capsule’s autonomous operational characteristics. Furthermore, similarities arising from internal pressure differentials within the Hyperloop capsule and those observed in hyperbaric chambers and highdifferential-pressure aircraft cabins were identified.
