First Claim
Patent Images
1. A fuel injection system for a gas turbine engine, the system comprising:
- a manifold ring having at least one circumferential fuel channel defined therein and at least one inlet in fluid communication with the fuel channel;
a plurality of spray tip assemblies in fluid communication with the fuel channel; and
a heat shield including at least two heat shield segments cooperating to at least substantially surround a cross-section of the manifold ring around a circumference of the manifold ring, the heat shield segments being detachably retained around the manifold ring by a plurality of removable fasteners.

- 12. A heat shield for an annular manifold of a gas turbine engine, the heat shield comprising a plurality of heat shield segments cooperating to define a hollow ring having a substantially closed cross-section, the cross-section being defined at any point about a circumference of the ring by at least two different ones of the heat shield segments cooperating with one another, and each of the heat shield segments extending around only a portion of the circumference of the ring.

17. A method of attaching a heat shield to a manifold ring, the method comprising:
-
placing at least first and second complementary heat shield portions around the manifold ring such that the heat shield portions cooperate to surround at least a major part of a cross-section of the manifold ring about an entire circumference of the manifold ring; and retaining each of the heat shield portions over the manifold ring with at least one removable fastener. - View Dependent Claims (18, 19, 20)
