ABSTRACT:
The attachment means for the TOBI of a gas turbine engine permits the use of the TOBI that is fabricated into a unitary unit. A spacer between the attaching flange of the TOBI, and a segmented ring overlying the flange allows the controlled flow of cooling air for reducing the thermal fight at the point of attachment.
