RISAirfoil Deflection Characteristics During Rub Events
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The turbomachinery industry continually struggles with the adverse effects of contact rubs between airfoils and casings. The key parameter controlling the severity of a given rub event is the ...
Experimental Results From Controlled Blade Tip/Shroud Rubs at Engine Speed
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results obtained for an Inconel® compressor blade rubbing a steel casing at engine speed are described. Load cell, strain gauge, and accelerometer measurements are discussed and ...
Casing Treatment and Blade-Tip Configuration Effects on Controlled Gas Turbine Blade Tip/Shroud Rubs at Engine Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results obtained for an Inconel® compressor blade rubbing bare-steel and treated casings at engine speed are described. Since 2002 a number of experiments were conducted to ...
Development of an Experimental Capability to Produce Controlled Blade Tip∕Shroud Rubs at Engine Speed
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental capability using an in-ground spin-pit facility specifically designed to investigate aeromechanic phenomena for gas turbine engine hardware rotating at engine speed is demonstrated ...
