To control the thrust the compressor operates at different mass flow rates to vary the compressor and turbine speeds [4]. A compressor ``stage'' is made up of a moving part (the impeller, or rotor) and a stationary part (the diffuser, or stator). There are currently two principal compressor designs found on jet engines: the axial compressor, … The pneumatic system supplies high temperature compressed air for air conditioning and pressurizing the airplane and for low pressure engine starts. Eliminating the pneumatic bleed results in a more efficient engine operation due to reduced overall airplane level power requirements — the airplane does not draw as much horsepower off the engine in cruise, so it doesn't burn as much .
