ANALYSIS OF THE ACTIVE MANAGEMENT OF EXISTING AIR CLEARANCES TURBOCOMPRESSOR ENGINES

Abstract

The purpose of this article is active clearance control analysis (ACC) between rotor and casing of turbine in gas turbine engines (GT). The article deals with clearance creation in GT. Also, there are analyzed ACC requirements and problem of tip clearance sensing in turbine. Also, there are described clearance control general principles, focused on the most widely used active thermal system clearance control (ATS). Also, there are described clearance control developments.
