Abstract
A turbine intermediate case in which the outer case element carries a series of inwardly extending struts that position the bearing support centrally within the outer case element and these struts support the inner case element within and in spaced relation to the outer case element. The inner case element carries seals at opposite ends, a diaphragm and a support ring for the row of turbine vanes downstream of the case. The struts provide a vent for the air cavity formed by the diaphragm and carry a baffle to control heat transfer between strut and vent air.
