Abstract:
The subject matter of this specification can be embodied in, among other things, a fuel injector for a gas turbine engine includes a fuel injector housing, and an elongated fuel tube held in position in said housing by spaced apart joints and including an undulating tube surface along at least a portion of its length between said joints, said undulating tube surface being in contact with another surface disposed in said housing at one or more locations of said undulating tube surface.

Claim (Index 10):
A fuel injector for a gas turbine engine, comprising:\n a fuel injector housing having an internal wall and internal passage therein; an elongated secondary fuel tube disposed in said internal passage, said elongated secondary fuel tube having an undulating outer surface along at least a portion of its length and having an undulating inner surface along at least a portion of its length, said undulating outer surface being in contact with said internal wall at one or more locations of said undulating outer surface; and\n an elongated primary fuel tube disposed in said secondary fuel tube and held in position therein by spaced apart joints, said primary fuel tube including an elongated outer surface along at least a portion of its length between said joints, said elongated outer surface being in contact with said undulating inner surface at one or more locations of said elongated outer surface to reduce fatigue failure at said joints during service in a gas turbine engine.
