Abstract
A turbocharger for a powered machine including a turbine is disclosed. The turbocharger may include a turbine wheel including a disk section, the disk section including a disk body, the disk body including a length extending between a longitudinal axis and a blade platform. The disk section may further include a shoulder section positioned radially outward the longitudinal axis, a neck section positioned radially outward the shoulder section and a throat section positioned radially outward the neck section, an upstream axial plane coextensive with an upstream side of the blade platform, a downstream axial plane coextensive with a downstream side of the blade platform. Further, the turbine burst shield section may have a geometry that peaks in depth in the burst plane which prevents ejection of secondary mass in the event of a turbine burst.
