Abstract
A manifold mounting arrangement comprising: a discrete manifold module; a clevis arrangement having a clevis straddling a flange and pivotally secured to the flange by a clevis pin; and a locking bar configured to be coupled to the clevis and to constrain the manifold module relative to the clevis arrangement in the locality of the locking bar. The invention finds utility for mounting case cooling manifolds to turbine casing for a gas turbine engine.

A manifold mounting arrangement for a gas turbine engine, the manifold mounting arrangement comprising:
- a manifold module having first and second ends;
- a clevis arrangement having a clevis configured to straddle a flange and to be pivotally secured to the flange by a clevis pin;
- and
- a locking bar configured to be coupled to the clevis and to constrain the manifold module relative to the clevis arrangement in the locality of the locking bar,
- wherein the manifold mounting arrangement mounts the manifold module to a part of the gas turbine engine.
A gas turbine engine comprising at least one manifold mounting arrangement, the at least one manifold mounting arrangement comprising:
- a manifold module having first and second ends;
- a clevis arrangement having a clevis configured to straddle a flange and to be pivotally secured to the flange by a clevis pin;
- and
- a locking bar configured to be coupled to the clevis and to constrain the manifold module relative to the clevis arrangement in the locality of the locking bar,
- wherein the manifold mounting arrangement mounts the manifold module to a part of the gas turbine engine.
A turbine case cooling arrangement comprising:
- a turbine case comprising a flange;
- a circumferential feed duct having arc-shaped rigid portions each coupled to a manifold module by an air transfer box, adjacent rigid portions coupled by flexible bellows portions;
- and
- at least one manifold mounting arrangement including:
- a clevis arrangement having a clevis that straddles the flange and is pivotally secured to the flange by a clevis pin;
- and
- a locking bar configured to be coupled to the clevis and to constrain the manifold module relative to the clevis arrangement in the locality of the locking bar, wherein
- said clevis arrangement is located towards a first circumferential end of the manifold module.
