Abstract: A gas turbine engine fan blade (34) having an airfoil portion (42) and a dovetail root portion (44) is enhanced by having spaced apart supporting ribs (65) extending into the dovetail root portion (44). The supporting ribs (65) define a plurality of hollow cavities (66) extending into the dovetail root portion (44) of the fan blade (34). The extended cavities (66) reduce the weight of each blade (34) and also improve the integrity of each blade (34).

Abstract: A method is provided that involves a wall (14) configured to circumscribe and be radially adjacent a rotor (12). During this method, a tri-axial capacitance probe (32) is provided that includes a tri-axial conduit with an outer conductor member. The tri-axial capacitance probe (32) is configured to output data indicative of a characteristic of the rotor (12). The tri-axial capacitance probe (32) is configured within a wall aperture in the wall (14). The outer conductor member is electrically coupled with the wall (12). The wall (12) is configured as a housing for the tri-axial capacitance probe (32).
