AIRCRAFT SYSTEM WITH GAS TURBINE ENGINE POWERED COMPRESSOR

An aircraft system (20) includes a gas turbine engine (22), a gearbox (26) and at least one compressor (24). The gas turbine engine (22) includes a compressor section (32), a turbine section (36), a combustor section (34) and a rotating structure (50). The combustor section (34) is fluidly coupled with and between the compressor section (32) and the turbine section (36). The rotating structure (50) includes a compressor section rotor (44) within the compressor section (32) and a turbine section rotor (46) within the turbine section (36). The at least one compressor (24) includes a compressor rotor (54) rotatably driven by the rotating structure (50) through the gearbox (26). The gas turbine engine (22) may be dedicated to powering the at least one compressor (24).
