Abstract
A power plant is shown having a turbine power unit with a gas producer for directing gases into the unit while an exhaust duct delivers gas from the unit and a drive shaft extends from the unit for delivering power. The turbine power unit includes a turbine rotor mounted in bearing assemblies in its front and rear end. The rear assembly is supported by rigid struts while the front bearing assembly is supported by the first stage vanes and an interconnecting specially constructed diaphragm with heat shields. The outer ends of the vanes are fixed to a cantilevered ring fixed to the turbine casing while the inner circumference of the diaphragm has a large interference fit with a cylindrical surface on the front bearing assembly housing.
