Specific electric spacecraft thrusters require cathodes to operate, and each thruster will require a different power output from its cathode. A cathode was created to fill the role of a low power emission cathode. Additionally, the cathode was designed to allow the disassembly and replacement of parts. This replaceability allows the components to vary in geometry. This variation ability turns this cathode into a future experimental platform. By changing the inner diameter of the cathode orifice, keeper orifice and the distance between the orifices, the effects can be studied to find the optimal geometries and dimensions for low powered cathodes.

Affordable ion propulsion hardware suitable for educational laboratories was needed due to the cost, size, and complexity of conventional ion thrusters. This challenge was addressed by redesigning a cathodeless gridded radio-frequency (RF) ion thruster to improve RF coupling efficiency, plasma stability, and reduce power losses. The work involved computational plasma modeling in COMSOL, mechanical
redesign of the discharge chamber, and construction of an L-type RF matching network, with design parameters verified using vector network and VSWR analyzers prior to plasma operation. Engineering activities included coil optimization, grid alignment and refinement, and impedance tuning at an operating frequency of 13.56 MHz. The resulting system provides a practical and modular platform that can be used for educational exploration of electric propulsion concepts and hands-on laboratory experiments.

Electrospray thrusters are a newer type of electric propulsion that can produce very small, well-controlled thrust for small spacecraft. To understand how well they work, we need good diagnostics to measure what’s coming out of the plume. This senior design project is focused on designing and building a Retarding Potential Analyzer (RPA) that can be used with an electrospray propulsion test setup. The goal of the RPA is to measure key plume properties, including ion energy distribution and beam current. These measurements help us evaluate thruster efficiency, study how the propellant breaks apart (fragmentation), and compare experimental results to propulsion models. Our RPA uses a multi-grid design. By applying and sweeping a retarding voltage, the device blocks ions below a certain energy while allowing higher energy ions through. We measure the collected current during the voltage sweep, and from that we can determine the energy profile of the beam. The design is being developed to work reliably in a vacuum environment and to integrate with existing lab electrospray test facilities. Overall, this project combines electric propulsion, plasma/beam measurement methods, instrumentation and data analysis to provide better experimental data for electrospray thruster development.

Engineering courses, particularly Control Systems, often lack real-world experiences to effectively illustrate theoretical concepts. To address this gap, a hands-on drone flight system was developed to demonstrate important concepts like feedback control. Multiple drone configurations that simulate a space rocket were modeled in SolidWorks, 3D printed and assembled. The system was programmed through the Arduino IDE and incorporated LiDAR sensing for real-time altitude feedback. The final interactive platform reinforces theoretical control concepts, like stability and feedback, by exposing them to the thrill of real-world control implementations, further supporting growth in an educational environment.
Design and Optimization of the Solar Car Aeroshell

The speed and efficiency of a solar car rely significantly on the aerodynamic body of the vehicle called an aeroshell. WMU’s Sunseeker solar car required a larger aeroshell to maximize solar panel array area while minimizing drag and weight. The geometry was designed in NX and optimized using computational fluid dynamic simulations in Ansys Fluent. Composite shell structural performance was evaluated through finite element analysis in Ansys Mechanical. Physical testing was done in a wind tunnel with application of Global Luminescent Oil-Film (GLOF) and composite panel destructive analysis further validating simulation predictions, ensuring aerodynamic and structural requirements are met.

This project investigated strategies to reduce aerodynamic noise from wind turbine blades by modifying the geometry and surface properties of a baseline NACA 0012 airfoil. Because turbine noise constrained modern wind projects, six modified configurations and smooth control were evaluated. All models were 3D printed with identical chords and span and tested in Western Michigan University’s anechoic wind tunnel under consistent operating conditions across a range of angles of attack. Sound pressure levels and spectra were measured using a fixed microphone position. Complementary Ansys Fluent simulations provided lift/drag coefficients, surface pressure distributions and near-wake flow fields. A decision matrix ranked concepts by noise reduction, manufacturability and cost.

A standardized, open-source aerodynamic reference model of a Le Mans Prototype 2 (LMP2) vehicle was developed to address the lack of publicly available geometries suitable for high-performance automotive research. A fully parametric 1: 10 scale model based on FIA technical regulations and common homologated chassis features was designed to support modular testing of key aerodynamic elements, including the diffuser and rear wing. Because Reynolds number similarity could not be achieved at scale, the study emphasized flow-field topology, focusing on the interaction between the diffuser and the rear wing. CFD simulations supported wind tunnel experiments using PIV and GLOF techniques.

Autonomous ground vehicles are increasingly important in modern robotics, with applications ranging from transportation to industrial automation. This project focused on the development of an autonomous ground vehicle for the Intelligent Ground Vehicle Competition (IGVC). The primary objective was to convert an electric wheelchair into a fully autonomous platform capable of navigating outdoor courses while detecting obstacles, following lane markings, and reaching designated waypoints. An engineering analysis was conducted to determine the best methods for sensor integration, mechanical mounting, and navigation control while meeting all IGVC safety and performance requirements.

In today's constantly evolving world, autonomous vehicles are becoming more common place. To address this, we are building an autonomous ground vehicle based on a donated electric wheelchair to compete in The Intelligent Ground Vehicle Competition (IGVC) in June 2026. The project has been developed using ROS2, Python, and C++. This project was split into two multidisciplinary teams of ME and CS students. Our responsibility is to handle perception and controls, including provisioning the lidar and camera to function as sensors for navigational data and implementing control algorithms for the vehicle to move. We were working with another Senior Design Group that will be responsible for navigation and sensor fusion. With our combined efforts we aimed to create a fully functional self-driving vehicle with the ability to sense its surroundings and intelligently plan a path forward.

Autonomous vehicles require reliable route planning and obstacle detection capabilities. Western Michigan University’s (WMU) Disability Services for Students (DSS) offers a vehicle for student transportation, which, while not autonomous, was developed to emulate an autonomous vehicle framework. A high-fidelity map of WMU’s main campus was created for use by this vehicle and was integrated into a ROS2-based visualization and routing framework. OpenStreetMap data, refined through on-site measurements, supported generation of a Lanelet2 map for localization, routing, and planning. Autoware tools enabled conversion and visualization in RViz, overlaying GPS tracking, LiDAR point clouds, routes, detected objects, and object trajectories. Recorded LiDAR, GPS, and IMU data were replayed using ROS bags to validate map and routing accuracy. This mapping and real-time visualization system provides a foundation for future navigation assistance research.

Faculty Advisor:
Dr. Jinseok Kim
Industrial furnaces with vertical lift doors required a safer locking system that eliminated ladder use. Existing designs forced operators to access elevated locking pins, creating significant fall hazards during maintenance and loading operations. A ground-operated mechanical locking mechanism was developed to provide a positive mechanical stop capable of supporting the full static door load with an appropriate safety factor. Engineering efforts included mechanical design, material selection, ergonomic analysis, parametric 3D modeling and finite element analysis. Prototypes were fabricated and evaluated for reliability, durability and ease of operation, improving operator safety and long-term usability in industrial environments.

Most hydraulic valve manifolds that were being used at Parker Hannifin were heavy and required external plumbing, while other lightweight designs were experiencing corrosion over time. Single-stage and dual-stage hydraulic valve manifolds are designed to support high-cycle hydraulic pump testing. This involves repeated loading and unloading with pressures reaching 5,000 psi. Extensive testing on these pumps are required to ensure longevity and aircraft safety while in use. The work included studying the requirements, designing 3D CAD models, creating detailed drawings and selecting the correct material for infinite fatigue life. Structural finite element analysis and internal fluid flow analysis were performed using simulation tools to evaluate stress, fatigue behavior, and pressure losses. The resulting designs reduced weight, eliminated external plumbing, increased corrosion resistance and improved long-term reliability for demanding hydraulic test environments.

Long lead times and high costs made it difficult to quickly create prototype parts used in automotive rubber mounting applications. A new mold insert system was developed to allow fast creation of prototype parts using 3D-printed plastic components. These printed components were designed to withstand the heat and pressure of the injection molding process and fit into existing manufacturing equipment. Material selection, computer modeling and prototype testing were used to verify performance under operating conditions. The final design reduced prototype lead time from several weeks to one day, lowered tooling costs and increased flexibility during early stages of product development.

Football helmets are designed to protect athletes’ heads, yet concussions remain a serious concern due to repeated high-impact collisions. This project developed and tested new ways to improve helmet safety by combining computer-based design, advanced 3D printing and standardized impact testing. Super-elastic materials were integrated into 3D-printed polycarbonate helmet structures to better absorb and dissipate impact energy. Controlled drop tests were used to compare different designs and evaluate their ability to reduce acceleration during impacts. By evaluating multiple design approaches for strength, weight and repeatability, this work contributes to safer, more effective helmet technologies for future athletes.

Accurate measurement of surface skin friction and flow behavior remains a critical challenge in aerodynamic research and Computational Fluid Dynamics (CFD) validation. This project addresses that need by applying the Global Luminescent Oil Film (GLOF) technique to a generic Formula 1 vehicle in a controlled wind tunnel environment. The high resolution and global measurement of skin friction that the GLOF technique provides make it possible to improve accuracy and precision in Aerodynamics study. The resulting dataset will provide detailed experimental data for advancing aerodynamic understanding relevant to Formula 1 and other high-performance vehicles.

The Fluid Power Vehicle Challenge (FPVC) is a competition in which teams design and race hydraulic powered vehicles. A recumbent bike was designed that uses a custom drivetrain, hydraulic system and user interface to achieve motion. The drivetrain was developed through analysis of vehicle kinematics, dynamics and human power limits. The hydraulic circuit was designed and simulated in Automation Studio; simulations were used to validate hydraulic modes and predict race performance. A regenerative brake system and Arduino-controlled manifold were simulated in LT-Spice, a circuit analysis software. The final bike exemplifies the challenge of developing an efficient, human-driven hydraulic vehicle.

Solid rocket motors exhibit inherent thrust and burn variability, which complicates precise apogee targeting. In the NASA Student Launch Initiative (USLI), teams are evaluated based on their ability to reach a predetermined target apogee, requiring effective compensation strategies to reduce trajectory uncertainty. To address this challenge, a deployable airbrake mechanism was developed to modulate aerodynamic drag during ascent. Both passive deployment and active feedback control approaches were investigated through numerical simulation. Subsequent flight testing, supported by onboard sensor measurements, enabled real-time apogee estimation and trajectory regulation while also assessing the controllability, reliability, and practical feasibility of each method for future implementation on WMU USLI vehicles.

Space debris poses an escalating threat to spacecraft and satellites as non-degradable hardware accumulates in LEO. This project developed an explosive bolt system using materials that degrade under LEO's unique conditions of elevated radiation, atomic oxygen, and atomic nitrogen. UV radiation spectrum testing confirmed degradation properties. Using CAD, FEA and fragmentation software, the bolt was engineered to withstand compressive and tensile forces up to one million pounds. Predictive models estimated orbital and material decay timelines, while scaling laws enabled mission-specific sizing. This degradable explosive bolt directly addresses space debris reduction by reducing continuing post-mission debris in Earth’s orbit.
