An aircraft air supply system for generating pressurized air includes a compressor (114, 214) configured to receive and pressurize a flow of outside air, a turbine (118, 218) operatively coupled to the compressor (114, 214) by a shaft and configured to drive the compressor (114, 214), a fluid pathway fluidly connecting the compressor (114, 214) to an environmental control system pack, an outflow pathway fluidly connecting a cabin of the aircraft to the turbine (118, 218), a surge relief pathway fluidly connecting the compressor (114, 214) to the outflow pathway and the turbine (118, 218), and a surge relief valve disposed within the surge relief pathway. In a first operational state, the surge relief valve is open to allow a flow of surge relief air to flow from the compressor (114, 214) to the outflow pathway via the surge relief pathway, the surge relief air further flowing through the turbine (118, 218).
