Effect of Blade-Casing Rub Event on Blade, Casing and Turbine Shaft in Gas Turbine Engine
Abstract: Numerical results obtained for an Inconel-718 compressor blade rubbing a stationary casing of gas turbine at engine speed are described in this paper. Higher performances of gas turbine depend on minimum clearance between rotating blade and stationary casing. But tighter clearances result in rub event at blade tips, transferring load on different parts of gas turbine in radial, axial and tangential directions. The axial, radial and circumferential loads are noted …
