Abstract
A variable area turbine nozzle vane is supported from stationary housing structure and disposed in a confined fluid flow path between the gas generator and the power turbine of a split shaft gas turbine engine. The radially innermost structure defining the flow path for the working fluid is supported by a strut passing through, and also supporting, a hollow variable vane so that no external support struts are present in the flow path of the working fluid.
