Gas turbine combustor barrier structures for spring clips

A barrier structure ( 302 ) blocks exit of spring clip fragments ( 317 ) that may break off from a spring clip assembly disposed between a gas turbine engine combustor ( 300 ) and a transition piece component ( 360 ). The barrier structure ( 302 ) may additionally comprise an aspect ( 326 ) effectiv...

Zusammenfassung:	A barrier structure ( 302 ) blocks exit of spring clip fragments ( 317 ) that may break off from a spring clip assembly disposed between a gas turbine engine combustor ( 300 ) and a transition piece component ( 360 ). The barrier structure ( 302 ) may additionally comprise an aspect ( 326 ) effective to restrict a spring clip's ( 310, 311 ) radially inward compression, thereby reducing or eliminating damage to the spring clip ( 310, 311 ) during shipping and handling. The barrier structure ( 302 ) additionally may comprise an aspect ( 330 ) to restrict access by a human hand to the free ends ( 318 ) of the spring clips ( 310, 311 ). This aspect ( 330 ) reduces or eliminates the undesired lifting of the compressor by grabbing the spring clips ( 310, 311 ) during combustor transport, installation or removal. Accordingly, barrier structure embodiments are provided that reduce stress on spring clips, and that prevent the exit of spring clips from a containment space partly formed by the barrier structure.
