Bleed air systems for use with aircraft and related methods are disclosed. An example apparatus includes a compressor having a compressor inlet, a compressor outlet, and a first drive shaft. The compressor outlet is to be fluidly coupled to a system of an aircraft that receives pressurized air, and the compressor inlet is to receive bleed air from a low-pressure compressor of an engine of the aircraft. The example apparatus includes a gearbox operatively coupled to the first drive shaft to drive the compressor. The gearbox is to be operatively coupled to and powered by a second drive shaft extending from the engine. The example apparatus also includes a clutch disposed between the first drive shaft and the gearbox to selectively disconnect the first drive shaft from the gearbox. 1. A bleed air system for an aircraft , the bleed air system comprising:a turbo-compressor including a compressor, a turbine, and a first drive shaft coupled between the compressor and the turbine, the compressor having a compressor inlet to receive bleed air from an engine of the aircraft and a compressor outlet to be fluidly coupled to a system of the aircraft that receives pressurized air;a gearbox operatively coupled to and powered by a second drive shaft extending from the engine; anda freewheel disposed between the first drive shaft and the gearbox to operatively couple the first drive shaft and the gearbox.2. The bleed air system of claim 1 , wherein claim 1 , during a first operating condition of the aircraft claim 1 , the freewheel is to operatively couple the first drive shaft to the gearbox such that the gearbox drives the first drive shaft to drive the compressor and claim 1 , during a second operating condition of the aircraft claim 1 , the freewheel is to enable the first drive shaft to rotate faster than an output of the gearbox.3. The bleed air system of claim 2 , wherein claim 2 , during the second operating condition of the aircraft claim 2 , the turbine is to drive the ...
