pressurisation
Maintaining atmospheric density
Pressurisation is the British spelling of pressurization, the process of maintaining or increasing air pressure in an enclosed space.
Aircraft cabins undergo pressurisation to keep passengers comfortable at high altitudes where outside air is too thin to breathe.
The term extends to any system that maintains pressure, whether in spacecraft, diving chambers, or industrial equipment.
The pressurisation system failed, forcing an emergency descent.
