Systems and methods for hydraulic fracturing

A pumping unit, comprising:

• a chassis;
• an enclosure disposed on the chassis, the enclosure housing a gas turbine engine and a gearbox operatively coupled to the gas turbine engine, wherein the enclosure comprises:
• a first lateral side;
• a second lateral side;
• and
• a door mounted on the first lateral side proximate to the gas turbine engine;
• an exhaust assembly connected to the gas turbine engine;
• an air intake duct connected to the gas turbine engine;
• an air treatment system connected to the air intake duct, the air treatment system comprising one or more inlet pre-cleaners configured to eject debris particles via inertia of the debris particles;
• a drive shaft having a first end and a second end, wherein the first end of the drive shaft is operatively coupled to the gearbox;
• and
• a pump disposed on the chassis, the pump comprising an input shaft operatively coupled to the second end of the drive shaft, wherein the gas turbine engine, the gearbox, the drive shaft, and the pump are disposed along a longitudinal axis of the pumping unit.

A hydraulic fracturing system comprising:

• a plurality of hydraulic fracturing units;
• a fuel line configured to supply fuel from a fuel source to the plurality of hydraulic fracturing units;
• and
• a first hydraulic fracturing unit of the plurality of hydraulic fracturing units comprising:
• a gas turbine engine;
• an enclosure housing the gas turbine engine;
• an exhaust assembly connected to the gas turbine engine;
• an air intake duct connected to the gas turbine engine;
• an air treatment system connected to the air intake duct, the air treatment system comprising one or more inlet pre-cleaners configured to eject debris;
• a gearbox operatively coupled to the gas turbine engine;
• a drive shaft having a first end and a second end, wherein the first end of the drive shaft is operatively coupled to the gearbox;
• and
• a pump comprising an input shaft operatively coupled to the second end of the drive shaft, wherein the gas turbine engine, the gearbox, the drive shaft, and the pump are disposed along a longitudinal axis of the pump, and wherein a longitudinal axis of the drive shaft is offset from a longitudinal axis of the input shaft of the pump.
