SHINGLED LAMINATED POROUS MATERIAL |
摘要 |
<p>D-3611 SHINGLED LAMINATED POROUS MATERIAL C-3161 A gas turbine engine combustor has a porous wall structure for directing coolant from a compressed air plenum into a combustion chamber to cool its inner surface; an outer lamina has a first hole pattern therein and an inner lamina diffusion bonded to the outer lamina has a second hole pattern offset from the first hole pattern to direct air from the air plenum in cross-flow relationship across internal walls to cool the outer and inner lamina and the outer lamina has a plurality of relief notches formed part way through its depth which are responsive to thermal gradients across the porous wall structure to break the outer lamina into a plurality of separated shingles thereby to prevent excessive stress formation in the porous wall structure; the inner lamina including flow control means to maintain a regulated flow of coolant from an inlet air plenum to the combustion chamber irrespective of the number of relief notches broken during operation of the gas turbine engine.</p> |
