Quartz lamp thermocycling rig for combustion liners
Improved combustor liner durability is a major design objective for advanced combustors. Combinations of low cycle fatigue, creep, oxidation and crack propagation are the damage mechanisms that reduce durability. Each of these mechanisms is a consequence of cyclic thermal loading. Closely controlled rig tests can simulate these damage mechanisms. Although rig testing requires duplicating the actual thermal strain range on a full size liner, it is economically more attractive than full-engine testing. A suitable rig for controlled cyclic thermal loading of large size cylindrical test specimens is developed using a 672 KW electric quartz lamp radiant heat source. The design objectives, operational features and development shake-down test results are presented in this paper. The development discusses deals specifically with combustor liner test specimens. The rig is also suitable for high temperature testing of large advanced material specimens including composite ceramics.
