This research explores the design, fabrication, and integration of morphing control surfaces for small-scale UAS using additive manufacturing techniques. To reduce costs and streamline the design process, fused deposition modeling (FDM) additive manufacturing was employed for component fabrication. An off-the-shelf Horizon Sport Cub S2 served as the testing platform, modified with a …

Wind-Resilient Solar: Harnessing Cfd For Enhanced Load Estimation, Aly Mousaad Aly

Faculty Publications

Solar panels are a cornerstone of renewable energy infrastructure, playing a pivotal role in global sustainability efforts. To ensure their resilience and long-term viability, accurate wind load estimations are essential for designing supporting structures, which account for nearly 50% of their total cost. However, traditional building codes lack comprehensive guidance for solar panels, resulting in inconsistent estimations due to discrepancies in scaled wall-bounded wind tunnel testing methodologies. These inaccuracies pose safety risks, increase costs, and hinder adoption. Emerging technologies like computational fluid dynamics (CFD) simulations offer a promising alternative by enabling full-scale analysis under realistic conditions of complete turbulence. This …

Small Laser-Textured Dimples For Improved Tribological Performance Of Cocrmo In Artificial Hip Joints, William B. Bennett, Min Zou

Mechanical Engineering Faculty Publications and Presentations

This study investigates the impact of small dimples on the tribological properties of CoCrMo (CCM) surfaces. Laser-ablated textures with 5 mu m diameter dimples were fabricated at varying aspect ratios (0.1, 0.2, 0.3) and surface densities (5%, 15%, 25%) to evaluate their effects on friction and wear when paired with ultra-high molecular weight polyethylene (UHMWPE) counterfaces. The results showed that small dimples significantly reduced and stabilized the coefficient of friction (CoF) and wear compared to untextured CCM and larger dimples as reported in the literature. The texture configuration with a 5% surface density and 0.1 aspect ratio achieved the best …

Bronco Evtol: Vfs 2024 - 2025 Dvbf, Caroline Barbar Askar, Lanie Pritchard, John Bowers, Jacob Finley, Gus Gianotti, Luke Helwee

Mechanical Engineering Senior Theses

Common vertical take-off vehicles, such as helicopters, have been useful for transportation, rescue, and fire-fighting applications. However, these vehicles contribute significantly to CO2 emissions and are extremely loud. Electric vertical take-off and landing vehicles ( e VTOLs) have been proposed as an alternative vehicle which can perform the same functions, without the costs associated with a helicopter. In this paper, we develop a conceptual design for an eVTOL which satisfies the requirements of the annual Vertical Flight Society's Design-Vertical-Build-Fly Competition. We focus our conceptual design on three subsystems: Propulsion, Airfoils, and Controls. These subsystem designs are verified using Finite Element …

Valve-Tec, Ethan Lung, Dan Pruin, Casey Lacuata, Leo Morris

Mechanical Engineering Senior Theses

This project explores the feasibility of replacing a traditional camshaft driven system with an electronically actuated camless design for internal combustion engines. The primary motivation is to improve engine efficiency, reduce emissions, and extend the relevance of combustion engines in a future leaning toward electrification. Traditional camshaft systems limit engine responsiveness and efficiency due to fixed valve timing. Our camless solution addresses these limitations by using solenoids controlled by microcontrollers to open and close the valves based on the crankshaft position. We developed a modular prototype that integrates both analog and digital hall effect sensors for crank angle detection, dual …

Trigger Buddy, Alex Requadt, Alan Chen, Max Fernandez

Mechanical Engineering Senior Theses

Gun violence in the United States, particularly unauthorized firearm use by children and impulsive suicides, remains a devastating public health crisis. Despite widespread use of gun safes and locks, many remain ineffective or inconvenient, with most unauthorized users accessing firearms that were either unlocked or secured with easily bypassed mechanisms. Biometric locks present a promising alternative, but existing products often fall short in speed, reliability, and usability. To address this gap, we developed Trigger Buddy, a biometric handgun lock designed to balance accessibility, durability, and security. Trigger Buddy mounts directly to a handgun's picatinny rail and uses a fingerprint sensor …

Accelerating High-Throughput Phonon Calculations Via Machine Learning Universal Potentials, Huiju Lee, Vinay I. Hegde, Chris Wolverton, Yi Xia

Mechanical and Materials Engineering Faculty Publications and Presentations

Phonons play a critical role in determining various material properties, but conventional methods for phonon calculations are computationally intensive, limiting their broad applicability. In this study, we present an approach to accelerate high-throughput harmonic phonon calculations using machine learning universal potentials (MLIPs) combined with an efficient training dataset generation strategy. Instead of computing phonon properties from a large number of supercells with small atomic displacements of a single atom, our approach uses a smaller subset of supercell structures where all atoms are randomly displaced by 0.01 to 0.05 UŮ, significantly reducing computational costs. We train a state-of-the-art MLIP based on …

Impact Of Delayed Artificial Aging On Tensile Properties And Microstructural Evolution Of Directed Energy Deposited Scalmalloy®, Rachel Boillat-Newport, Sriram Praneeth Isanaka, Frank Liou

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Scalmalloy® is a novel alloy designed to work with the unique processing inherent in additive manufacturing (AM). This alloy is post-processed using a single artificial aging treatment rather than a multistep heat treatment, as often noted in traditional manufacturing processes. Much of the literature details the impact of direct aging treatments around the temperature and time recommended by the manufacturer, 325 °C for 4 h; however, few studies have explored the impact of delayed artificial aging on the resulting mechanical and microstructural behavior. This study explored this missing link and determined the impact that the time between the fabrication of …

Investigating The Discrepancies Between Acoustic And Radar Measurements Of Water Level Using Data Analysis And Computational Modeling, Ohiedul Haque Mohammad Asad

Civil & Environmental Engineering Theses & Dissertations

Observations indicate that there is a discrepancy between water level measurements from NOAA’s acoustic gauges and radar gauges. NOAA’s acoustic gauges use a downward-looking acoustic sensor that measures the instantaneous distance from the sensor to the water level. To create a calm water surface for measurements, the sensor is placed in a PVC tube that penetrates the water surface to a certain depth. This tube is called the stilling well. In this thesis, discrepancies in water level measurements from acoustic and radar sensors were explored through data analysis and computational modeling. Specifically, the correlations between the error, which is defined …
