Turbine casing delimiting an annular gas flow stream divided by radial arms

A turbine casing includes circumferential walls delimiting an annular stream for the flow of gases. The radial arms traversing the stream are completed by a channeling part on the downstream side which is bolted to the arms. The walls are formed of butt-joined tiles assembled together and joined to...

More Information
Summary:A turbine casing includes circumferential walls delimiting an annular stream for the flow of gases. The radial arms traversing the stream are completed by a channeling part on the downstream side which is bolted to the arms. The walls are formed of butt-joined tiles assembled together and joined to collars situated on the arms and the channeling parts by riveted ridge tiles. The invention results in a reduction of resistance to the flow of gases, as well as absorption without the production of excessive stresses of the original thermic dilations in the walls.
