RISDesign and Experimental Validation of Compact, Quick Response Shape Memory Alloy Separation Device
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The shape memory alloy (SMA)actuated separation devices that are currently used in small satellites were usually designed to handle large separation loads. As a result, they have complex structures, large footprints, and ...
Investigation on Material's Fatigue Property Variation Among Different Regions of Directional Solidification Turbine Blades—Part I: Fatigue Tests on Full Scale Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: At present, directional solidification (DS) made blades are commonly used in high performance turbine for their better high temperature mechanical, especially in creep properties compared with the equiaxed grain (EG) blades ...
Investigation on Material's Fatigue Property Variation Among Different Regions of Directional Solidification Turbine Blades—Part II: Fatigue Tests on Bladelike Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Part I of this investigation is mainly focused on fatigue tests of full scale turbine blades, based on the observation of the phenomena that some directional solidification (DS) blades do not fracture at their maximum ...
Effect of Aluminized Coating on Combined Low and High Cycle Fatigue Life of Turbine Blade at Elevated Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Some cracks were detected on the fir-tree root of turbine blade in an in-service aero-engine, and the aluminized coating was considered to be the main cause of these cracks. To study the effect of aluminized coating on ...
