RISInvestigation of a HighPressure Turbine Stage in a HighSpeed Rotating Transient Test Facility for Rotor Tip Study and a Parametric Study for Improved Heat Transfer Calculation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The first part of the paper presents commissioning of a singlestage highpressure (HP) turbine employed in a series of extensive experiments to study the aerodynamics and heat transfer on the rotor surface and casing liner. ...
An Aerodynamic Investigation of a High-Pressure Turbine Using Rotor Casing Static Pressure Measurements at Engine Representative Conditions With Different Tip Designs, Tip Gaps, and Inlet Temperature Profiles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A rotating high-pressure (HP) turbine, in modern aircraft engines, is subjected to high cyclic thermal and mechanical loads. Shroudless turbines experience high heat loads on the rotor tip and casing, which makes them one ...
Understanding Thermal Unsteadiness in Engine Representative Flows and Improved Methodologies for Derived Heat Transfer Calculations Using Thin-Film Gauges
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Oxford Turbine Research Facility (OTRF) is a high-speed rotating transient test facility, which allows unsteady aerodynamic and heat transfer measurements at engine representative conditions. In addition, a variety of ...
