(54) System and method for adaptive impingement cooling


(57) An adaptive cooling structure comprises a mounting support 44, a liner 42, and a spacer 66. The mounting support 44 has a coolant aperture 62 for directing cooling air AC through the support 44. The liner 42 has a first surface 52 facing away from the mounting support 44 and a second surface 54 facing towards the support 44. The liner 42 is coupled to the mounting support 44, and the spacer 66 is positioned between the support 44 and the liner 42. The positioning of the spacer 66 creates a chamber 70 between the mounting support 44 and the liner 42, thus allowing the cooling air AC to impinge on the second surface 54 of the liner 42. The liner wall 48 is configured to deflect away from the mounting support 44 to expand the chamber 70, thus allowing the cooling air AC to further impinge on the second surface 54 of the liner 42.
