232 Romuald Tarczewski 5.3 Air Supplying System Air-inflated shell can be exploited only,when equipped in an efficient air sup- plying system.This system should assure unfailing inflation and deflation of cushions and maintenance of internal working pressure.It should be foolproof. An exemplary solution is a system integrated with cushions.It consists of the web of internal pressure conduits,placed inside cushions.These conduits are linked by means of self-tightening,male connectors.Junction modules are situated at side-bottom corners of the cushion.This facilitate coupling eliminates any external part of the conduits.Air pressure inside the conduits is significantly higher than the working pressure in the cushions.The mentioned above junction,contains control unit (valves)regulating internal pressure. When the pressure decreases,the valve opens and air from the conduit is forced inside.When the pressure increases,e.g.in the case of elevated temperature, the valve ejects needless air outside.The same function is used for deflation. It is possible to use special explosive cartridges for very quick (instant)in- flation.In that case,a suitable socket is used in the junction of air-supplying system.The cartridge,placed in this socket,can be detonated manually or by remote control.Explosion products fill the cushion and the control valve main- tains the pressure.Fig.16 presents a functional diagram of junction module in the air supplying system.
