An air conditioning system for an aircraft includes cascaded high and low pressure turbines, an electric generator that is driven at variable speeds by the low pressure turbine, and a fan that is also driven by the low pressure turbine. During operation of the air conditioning system, ac power is generated by the electric generator and provided to electrical equipment onboard the aircraft. Because the electric generator is driven at variable speeds, it generates ac power having variable frequency. The air conditioning system further includes a bypass val...


[ We claim:] [1.] An air conditioning system comprising:a first spool including a high pressure turbine;a second spool including a low pressure turbine, an electric generator; and a device having a non-linear load line, the low pressure turbine being cascaded with the high pressure cooling turbine, the electric generator generating ac power at variable frequencies when driven at variable speeds by the low pressure turbine; anda bypass valve for bypassing the high pressure turbine;the bypass valve increasing the speed of the electric generator to maintain...
