Abstract
Systems and methods of coupling a nose cone to a turbine machine. Nose cone assembly weight and coupling difficulty are each reduced by reducing or eliminating the number of bolts used to mount the nose cone to the turbine machine, as well as the support or retaining ring. The disclosed nose cone comprises a plurality of hub mounting elements including one or more bayonet flanges, two or more apertures defined by a flange forming an annular hub mating surface of the nose cone and configured to receive an fastener therethrough, and one or more pilot flanges.
