GAS-TURBINE ENGINE STARTING METHOD Russian patent published in 2006 - IPC F02C7/26 

FIELD: mechanical engineering; gas-turbine engines.

SUBSTANCE: starting of gas-turbine engine included into group of gas-turbine engines installed at station, each containing cycle compressor with delivery main line with installed regenerator, is provided by means of starting turboexpander to which starting gas mainline and air main line with shutoff members are connected. First of all first gas-turbine engine of group is started by delivering starting gas to its starting turboexpander. Then following gas-turbine engine is started by delivering to its starting turboexpander air from delivery main line of cycle compressor of operating gas-turbine engine. Air is taken from delivery main line before regenerator or after regenerator or simultaneously before and after regenerator.
