Principles of operation of
an air domes
Light shell and efficient inflation system allow the hall to be used in all weather conditions – the hall is resistant to wind load and snow load. Internal pressure presses the tight PVC membrane against the steel cable mesh which takes over all the loads and transfers them to the foundations (ballasts). The conditions inside an air dome are identical to those in a typical, traditional sports hall.
The air blow-in from fans increases the internal pressure of 250-350 Pa (2,5-3,5 hPa) which corresponds to the load of 25-35 kg/m². The increase of pressure is harmless and imperceptible for the human body – in our daily life we experience several times higher pressure fluctuations, of up to several dozen hectopascals (hPa), caused by changes of weather conditions.
