Advanced Compressor Seal Tests.

Abstract

The continuation of the development of a new resilient seal concept entitled the 'J'-Seal is described. The concept uses a pressure loaded membrane and hydrostatic bearing principles to maintain a minimum stator to rotor clearance. Following the development of a complex seal analyses performed in an earlier phase of this program, the seal was built and tested. Seal distortions due to inadequate manufacturing techniques have been substantially reduced through the use of brazing with a high temperature gold alloy instead of welding. The test results presented in this report support the analytically predicted trends. (Author)
