Experimental and numerical investigation of annular casing impingement arrays for faster casing response

Abstract:

The Transient Heat Transfer Facility was developed to test fullscale high pressure compressor and turbine casing air systems using gas turbine engine representative secondary air system conditions. Transient casing response together with blade and disc responses governs achievable tip clearances in both compressors and turbines. This paper investigates the use of air impingement as a means to speed up the casing response. The thermal growth of the casing was characterised by surface temperatu...
