RISPhysical Mechanisms Investigation of Sharkskin-Inspired Compressor Cascade Based on Large Eddy Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To survive in a complex environment, nature has produced efficient and versatile resource-rich structures. One of the novel drag reduction designs comes from the efficient movement of sharks through microscope riblets ...
Surplus Torque Elimination Control of Electro-Hydraulic Load Simulator Based on Actuator Velocity Input Feedforword Compensating Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electro-hydraulic load simulator (EHLS) is a typical closed-loop torque control system. It is used to simulate the load of aircraft actuator on ground hardware-in-the-loop simulation and experiments. In general, EHLS is ...
Control of Shroud Leakage Loss and Windage Torque in a Low-Pressure Turbine Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As new aeroengine architectures move to larger diameter fans and rotors, the associated increase in weight will need to be counterbalanced by lighter, more compact, and more efficient low-pressure turbines (LPT). Efficiency ...
Windage Torque Reduction in Low-Pressure Turbine Cavities Part I: Concept Design and Numerical Investigations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The windage torque on rotational walls has a negative effect on the performance of the low-pressure turbine. In this paper, three novel flow control concepts (FCCs) were proposed to reduce the windage torque within a turbine ...
