Zusammenfassung:	According to the present invention, there is provided a turbomachine rotor assembly having a blade mounting means comprising a rotor spool defining a flowpath surface and having at least one circumferential dovetail shaped retaining groove therein. A plurality of radially extending blade members each comprising a dovetail root are positioned in the retaining groove of the rotor spool. The root comprises a pair of axially oppositely extending asymmetric shoulders having radially outwardly facing and differentially radially spaced contact surfaces for mating with complementary surfaces of the retaining groove of the rotor spool.
