摘要

A filter cleaning system is provided for a gas turbine engine including a compressor section and a combustor section. A mechanism is operatively connected to the gas turbine engine and is configured to be driven by the gas turbine engine in a first mode and configured to drive the gas turbine engine in a second mode. A first flow path is for delivering compressed air to the compressor section. At least one air filter is configured to filter air entering the first flow path. A second flow path is for delivering compressed air from the compressor section to the combustor section in the first mode. A third flow path is for delivering compressed air from the compressor section to the at least one air filter during the second mode.
