The GE38's compressor (5-stage axial + 1-stage centrifugal) should offer improved characteristics compared to the incumbent AE1107's 14-stage axial compressor (a product of its T56 heritage). As discussed in the previous V-22
thread, axi-centrif compressors are less sensitive to erosion/corrosion, with our very own Paco estimating that the axi-centrif configuration "increases an engine's resistance to [compressor stalls] by about 10 times."
