A Numerical Study and Optimization of a Morphing and Pitching Boeing Vertol VR-12 Rotorcraft Airfoil
(North Dakota State University, 2022)
The helicopter blade has not undergone any major change in design in recent history, only minor adjustments like swept blade tips, variable twist blade, and application of small gurney flap style trailing edge devices. ...
An Investigation on Residual Stress Build-Up in Cold Sprayed Metallic Samples: Effect of Stress Relaxation Heat Treatment
(North Dakota State University, 2022)
Residual stress formation during cold spraying process may result in deteriorative effects on the performance of coating materials. The objective of this investigation is to characterize residual stress built-up in some ...
Influences of Seawater Flows on the Degradation of Organic Coatings Applied on Offshore Wind Turbines
(North Dakota State University, 2022)
The regular protection methods of offshore wind structures consist of the application of two or three layers of epoxy-based coatings with a polyurethane topcoat. The coating systems of offshore wind turbines are mostly ...
An Experimental Study of Fluid-Structure Interaction in Collapsible Vessels
(North Dakota State University, 2022)
The fluid-structure interaction in collapsible thin-walled vessels is an important topic of research to better understand the physical mechanisms behind many physiological processes and diseases. In this work, we established ...
Regolith Based Polymer Matrix Composites for In-Situ Additive Manufacturing for Long Term Extraterrestrial Missions
(North Dakota State University, 2022)
The completed study investigated Martian regolith simulant composites’ material properties when there was variation in the type of used Martian regolith simulant. Four types of Martian regolith simulant were mixed at varying ...
Development and Characterization of Reactive Extrusion Additive Manufacturing System and Polymer
(North Dakota State University, 2021)
Additive manufacturing with polymers can rapidly produce complex geometry and prototypes but does not usually utilize thermoset polymers aside from photocurable polymers. In this study two-part reactive thermoset resin ...
Experimental Study of Effects of Leading-Edge Structures on the Dynamic Stall of a Vertical Axis Wind Turbine Airfoil
(North Dakota State University, 2020)
Vertical axis wind turbine, developed as one of the main methods to utilize the wind energy, has a promising future; however, the major issue to limit its performance is the uneven loading on the blade during operation. ...
