Abstract
Time lost in recharging compressed gas storage bottles on board aircraft is minimized with a fast recharge compressor (20) for rapidly providing compressed gas (30) having a housing (24) with a gas inlet (26), a shaft (46) within the housing (24) on which is mounted a turbine (34) and a multi-stage compressor (36). The turbine (34) is designed to run the shaft (46) and thereby the multi-stage compressor (36). Entering gas is divided into two streams and one stream (28) is directed through the turbine (34) while the other stream (30) is directed through the compressor stages (38,40,44). Heat is exchanged between the two streams by heat exchangers (52,54,56,57,60) after the expansion stream (28) has passed through the turbine (34) so as to cool the compression stream (30).
