Abstract

967,777. Gas turbine plant. GENERAL ELECTRIC CO. Dec. 21, 1962, No. 48365/62. Heading F1G. In a cooling arrangement for a gas turbine engine, compressor air flows through a passage between the combustion chamber flame tube and the engine outer casing, the turbine casing has axially spaced flanges for supporting shrouds and cooling tubes pass from the air passage through the upstream flanges into the downstream flanges to provide air from the passage to the flanges and shrouds. A gas turbine engine having a compressor 1, combustion equipment 2 and a turbine 3 has cooling air passages 13, 14 between the annular flame tube 9 and the outer and inner casings 7, 8. The turbine casing 20 is attached to casing 7 at 21 and carries flanges 22, 23 supporting rotor blade shrouds 24, 25. Tubes 31 having closed upstream ends 33 and air inlet holes at right angles to the airflow pass through the upstream flange 22 to the downstream flange 23 and supply cooling air from the passage 13 to the flanges and shrouds through ports 36, 35 and passages 40, 41. The cross-sectional area of each inlet hole in a tube 31 is less than the cross-sectional area of the tube.
