The invention is related to the gas turbine stators of the gas turbine engines applied in aviation. The gas turbine stator, in the outer housing of which sectors of the split honeycomb ring (made as double-layer one) are installed with support elements on the front and rear axial ends of the sector. In this invention, the layer of the sector facing the outer housing is made U-shaped in the plane, the support elements are made as separate rotary bodies distributed uniformly along the circumference and the front support elements (on the gas flow direction) are larger than rear ones in terms of geometrical dimensions by factor 1.1 . . . 1.5. Therefore, the implementation of the invention proposed with the characteristic features above, in conjunction with the known features of the invention claimed enables reduction of the gas turbine stator weight and improvement its reliability without compromising the turbine efficiency.

A turbocharger according to an embodiment is a turbocharger including a turbine housing for housing a turbine wheel rotary driven by an exhaust gas, a bearing housing for housing a rotational shaft on which the turbine wheel is mounted, the bearing housing being adjacent to the turbine housing, and a wastegate portion including a bypass passage and a valve body, the bypass passage allowing the exhaust gas to bypass the turbine wheel, the valve body being able to adjust a flow rate of the exhaust gas flowing through the bypass passage. In the turbine housing, a scroll passage for supplying the exhaust gas to the turbine wheel is formed by casting, at least on a radially outer side of the turbine wheel. A fastening portion for fastening the turbine housing and the bearing housing is disposed on a radially outer side of the scroll passage.

A turbocharger includes a turbine housing that is a cast component, a turbine scroll passage, a discharge port, and a discharge port defining member. The turbine scroll passage surrounds the circumference of a turbine chamber defined in the turbine housing and the circumference of the turbine chamber. Exhaust gas that has passed through the turbine chamber is conducted to the discharge port. The discharge port defining member constitutes a wall surface of the discharge port. The discharge port defining member includes a tubular main body wall and an outer circumferential edge. The main body wall constitutes a wall surface of the discharge port. The outer circumferential edge extends from the distal end of the main body wall and outward in the radial direction of the impeller shaft. The outer circumferential edge is fixed between the turbine housing and a downstream exhaust pipe, which is connected to the discharge port.

A gas turbine engine includes a compressor section. A diffuser case is downstream of the compressor section. There is a combustor and a turbine section. A bearing compartment is inward of the combustor. A shaft connects the turbine section to the compressor section. The bearing compartment includes a bearing that supports the shaft. A plurality of tubes extend to the bearing compartment. Each of the plurality of tubes have a heat shield that includes a first half and a second half crimped together along lateral edges.

An insert is disposable between an exterior surface of an annular body and an annular flange and between a support wall supportive of the annular flange and surface features of the exterior surface. The insert includes a forward section sized to fit between and to extend along respective arc-segments of the exterior surface and the annular flange and an aft section. The forward section includes a first end wall abuttable with the support wall, a second end wall and inner and outer diameter surfaces that extend between the first and second end walls for abutment with the exterior surface and the annular flange, respectively. The aft section extends from the second end wall to be engageable with the surface features.
