Abstract
A ceramic hybrid structure () that includes a wavy ceramic matrix composite (CMC) wall () bonded with a ceramic insulating layer () having a distal surface () that may define a hot gas passage () or otherwise be in proximity to a source of elevated temperature. In various embodiments, the waves () of the CMC wall () may conform to the following parameters: a thickness () between 1 and 10 millimeters; an amplitude () between one and 2.5 times the thickness; and a period () between one and 20 times the amplitude. The uninsulated backside surface () of the CMC wall () provides a desired stiffness and strength and enhanced cooling surface area. In various embodiments the amplitude (), excluding the thickness (), may be at least 2 mm.
