<P>PROBLEM TO BE SOLVED: To provide a more efficient and cost effective cooling of a combustor in a gas turbine engine. <P>SOLUTION: A venturi (210) for use in the combustor (200) of the gas turbine engine, the venturi including two non-integrally formed pieces: a forward piece (302) and an aft piece (304). The forward piece (302) includes a forward axial extension (306), a converging wall section (308), and a diverging outer-wall section (310). The aft piece (304) includes an aft axial extension (312) and a diverging inner-wall section (314). The forward piece (302) and the aft piece (304) are configured such that the diverging inner-wall section (314) resides in close, spaced relation to the diverging outer-wall section (310) such that a circumferentially extending cooling slot (316) is formed therebetween. <P>COPYRIGHT: (C)2012,JPO&INPIT |
