The Problem of Ensuring the Tightness in Hyperloop Passenger Systems

For Hyperloop passenger systems, we are discussing the problem of ensuring the tightness of a passenger capsule due to ultra-low pressure in the tube of the system. Based on the example of a particular system, we calculate the estimated time for the expiration of air from the capsule in an emergency situation. As a result, we are discussing several ways to improve the level of passenger safety associated with the leakage problem.
