摘要 |
A new and improved gas turbine engine augmentor including a liner having a film-coolable first portion joined to a convection-coolable second portion is disclosed. A cooling gas, such as fan bypass air, is channeled to the liner for film cooling the first portion and providing a residual cooling film to the second portion. The second portion is also convection coolable by air passing over an outer surface thereof. In a particular embodiment of the invention, the augmentor liner also includes a screech portion disposed at an upstream end of the first portion and downstream of a flameholder. The screech portion includes a substantially imperforate outer wall and an inner wall spaced therefrom which define a manifold therebetween. The inner wall includes a plurality of apertures in flow communication with the combustion zone. The manifold and apertures are effective for suppressing screech while substantially preventing the leakage of cooling air therethrough. |
