Abstract

A turbine engine (10) includes an engine core (11) extending along an engine centerline (20) and includes a compressor section (12), a combustor (14), and a turbine section (16) in serial flow arrangement. A set of blades (30) are circumferentially arranged in the turbine section (16) and the compressor section (12). A set of dovetails (52) mounts the set of blades (30) to a disk (32), rotated about the engine centerline (20). Each dovetail (52) can include a first upper lobe (110) and a first lower lobe (112) defining a first intervening recess (114), and a second upper lobe (120) and a second lower lobe (122) defining a second intervening recess (124), collectively defining a neck (130) for mounting to the disk (32).
