The strut supporting the diffuser to the engine outer case wall which also supports the shaft bearing of a turbine engine is conically shaped having its base located downstream with respect to the flow of the engine working medium and is judiciously angled so that the line of action for the bearing load is aligned to coincide with this angle, pass through the strut and intersect the centerline of the engine and the midpoint of the bearing. This enhances the stiffness of the support, reducing the weight necessary to support the same load. The diffuser case and support from the diffuser to the bearing is offset from the strut to minimize direct radial thermal incompatibility and the diffuser is spaced from the outer engine case wall reducing thermal stresses.

Diffuser case for a gas turbine engine

This invention relates to means for preventing the gap adjacent the tips of the blades of a rotor in a turbine type power plant from increasing as a result of rotor sag occasioned when an oil damped bearing is utilized.

Viscous damper with rotor centering means

A gas turbine engine and structure for mounting the gas turbine engine on an aircraft is disclosed. Techniques for controlling the magnitude of engine case deflection from the axis of the engine are developed. The transfer of a portion of the gust and thrust loads externally of the engine case to a location downstream of the rearward engine mount generates a reverse moment which counteracts deflection in the engine case.
