A compressor flowpath includes circumferentially spaced apart airfoils having axially spaced apart leading and trailing edges and radially spaced apart outer and inner ends. An outer wall bridges the airfoil outer ends, and an inner wall bridges the inner ends. One of the walls includes a flute adja
A compressor flowpath includes circumferentially spaced apart airfoils having axially spaced apart leading and trailing edges and radially spaced apart outer and inner ends. An outer wall bridges the airfoil outer ends, and an inner wall bridges the inner ends. One of the walls includes a flute adjacent the leading edges for locally increasing flow area thereat.

The set fastening, ejecting, and stacking system of claim 1, wherein said automatic dynamic ramp system for temporarily lifting up said area of said set with said set fasteners is driven by engagement with said set ejector. 3. The set fastening, ejecting, and stacking system of claim 1, wherein said automatic dynamic ramp system for temporarily lifting up said area of said set with said set fasteners comprises a foldable member that is at least partially folded up vertically by said horizontal movement component of said set ejector. 4. The set fastening, ejecting, and stacking system of claim 1, wherein said automatic dynamic ramp system for temporarily lifting up said area of said set with said set fasteners comprises a hinged plate member that is at least partially folded up vertically about said hinge by engagement with said set ejector. 5. The set fastening, ejecting, and stacking system of claim 1, wherein said automatic dynamic ramp system is automatically lowered by reverse movement of said set ejector. 6. The set fastening, ejecting, and stacking system of claim 1, wherein said set ejector has a substantially horizontal movement against said set for substantially horizontal ejection of said set onto said stack of sets, which stack of sets is at about the same level as said set being ejected. 7. The set fastening, ejecting, and stacking system of claim 1, wherein said set fasteners are staples, and comprising a set compiling and stapling area for compiling and stapling the sheets of said set, which set compiling and stapling area is partially shared with said stack of sets, and wherein said set ejector ejects said set out from said compiling and stapling area fully onto said stack of sets. 8. The set fastening, ejecting, and stacking system of claim 7, wherein said set ejector has a substantially horizontal movement against said set for substantially horizontal ejection of said set onto said stack of sets, which stack of sets is at about the same level as said set being ejected. 9. In a method of compiling and fastening together plural printed sheets into a fastened set in a compiling area, and ejecting and stacking said fastened set in an adjacent stacking area on top of a stack of other printed sheet sets, which fastened set has at least one set fastener in a fastening area, wherein said fastened set is ejected by a set ejector with a horizontal movement component over said other printed sheet sets in said stacking area, the improvement comprising automatically temporarily lifting up said fastened set in said fastening area from underneath said fastened set while said set is being ejected by said set ejector so that said fastened set slides out over said stack of other printed sheet sets in said adjacent stacking area without snagging of said set fasteners therewith. 10. The method of compiling and fastening together plural printed sheets into a fastened set in a compiling area, and ejecting and stacking said fastened set in an adjacent stacking area on top of other printed sheet sets of claim 9, wherein said automatically temporarily lifting up of said fastened set in said fastening area from underneath said fastened set while said set
