Honors Theses

The thesis covers automation complacency in the aviation industry. The purpose being to provide a foundation of complacency-related accidents to support or dismiss the Federal Aviation Administration’s claim to automation-induced inattention. Complacency factors are outlined in a multitude of fields, creating a background for aviation discussion. To outline the parameters of literature review, behaviors associated with complacency are addressed. Next, a compilation of accident reports is examined and categorized. Specific, impactful accidents relating to complacency are detailed and explained. Summarily, three solutions to human-driven complacency are proposed, evaluated, and analyzed. Including the following: proficiency advancement, technology improvement, and change in …

The paper then dives into the criteria for being a mentor or mentee and the schedule of the test program. The goals are then outlined for this initial program in a chart. There are five goals for the program to assist students with the transition …

Mental Health In Aviation: A Study Of Aviation Students On Their Perceptions Of The Federal Aviation Administration’S Rules Governing Mental Health, Laila Stein

Honors Theses

This study aims to understand collegiate aviation students, faculty, staff, and flight instructors’ perceptions of the Federal Aviation Administration’s (FAA) regulations governing mental health assistance. It also aims to examine the impact of the perceptions held by students, faculty, staff, and flight instructors regarding their desire to seek mental health assistance. A study at Western Michigan University’s (WMU) College of Aviation (COA) was developed to test the hypothesis that students, faculty, staff, and flight instructors had a restrictive perception of the FAA rules regarding seeking mental health assistance, and that students, faculty, staff, and flight instructors had lower desire to …

Analysis And Mitigation Of Pneumatic Regulator Resonance, Luke Fouch

Honors Theses

Internal resonance in pneumatic regulators can result in heavy leakage, which can lead to less efficient processes. To address this issue, two simulations were developed to simulate pneumatic regulation systems. The first simulation involved deriving a mathematical model of the equations of motion for a regulator and applying it using MATLAB. The second simulation involved developing a Simulink model that incorporated physical regulator properties. To verify the accuracy of both models, physical testing data was used. After verification, the models were modified in various ways to determine the main drivers of resonance in pneumatic systems. Additionally, Finite Element Analysis was …

Api Drying And Packaging Technology Upgrades, Destiny Washington

Honors Theses

Certain classes of active pharmaceutical ingredients (APIs) require higher levels of containment during handling. This project explores upgrades and new technology to improve currently used systems. The upgrades will include containment during drying and packaging while maintaining required ergonomic, industrial health, and GMP requirements. Design of this system and a full economic analysis have been performed for these upgrades.

This project details the profits and costs that are associated with the conversion of the API drying process from a batch process to a semi continuous process using an agitated thin film evaporator. The implementation of the new equipment is expected …

Thermal Control For A Miniaturized Fabry-Perot Interferometer In A Cubesat, Callie Pilkington

Honors Theses

The evaluation of neutral winds is critical in understanding the ever-changing weather and climate of the thermosphere, which can develop into a hostile environment for satellites. To measure these neutral winds, Michigan Aerospace Corporation is developing a 6U CubeSat that utilizes a miniaturized Fabry-Perot interferometer. For ideal operation, the Fabry-Perot interferometer requires a closely maintained thermal environment. These requirements are crucial in obtaining accurate measurements and for sustaining instrument and mission life due to the vast temperature range experienced in the thermosphere. With the solutions outlined in this proposal, the goal is to provide Michigan Aerospace with an optimized configuration …

Air Pre-Heat System Optimization For Flash Dryers, Sophia Louden

Honors Theses

Primient, a leading producer of food and industrial ingredients made from plant-based, renewable sources is the industrial sponsor for this project. The company is currently using Plate & Frame Heat exchangers to heat up a 40% by-weight glycol and water solution that is then used to preheat the incoming ambient air. Glycol is being added to reduce the risks of freezing in the system during the winter season. It is important to highlight that this fact affects the heat transfer properties of the liquid overall. Since air heating is a highly energy-demanding process, an outlet stream of hot water produced …

Design Of A Dynamometer Test Platform For Formula Sae Internal Combustion And Electric Powertrains, Ryan Bare

Honors Theses

This dynamometer project was completed for the Formula SAE team at Western Michigan University and aimed to deliver a functional and safe engine dynamometer test stand. Formula SAE is a student organization that designs and manufactures a new formula style race car from the ground up every year to compete at an international collegiate competition. The purpose of the dynamometer is to allow the team to tune their internal combustion (IC) engine and the newly developed electric powertrain (EV). The engine dynamometer is important to the Formula team as it will allow engine tuning and diagnosis prior to the completion …

Design And Implementation Of Test Stand Upgrades For Investigating Gearset Churning Losses With Baffles, Matthew Martin

Honors Theses

The automotive industry is continually researching ways to decrease energy losses in drivetrain applications. Rotating gear sets in an oil bath suffer frictional losses due to oil churning. The Center for Advanced Vehicle Design and Simulation (CAViDS) consortium has proposed studies to understand and reduce these churning losses. The primary means to reduce these churning losses are to redirect the oil flow using baffles and/or alter the oil viscosity. To perform churning loss optimization under controlled conditions, an existing test stand was upgraded to improve safety, introduce oil temperature control, and allow for the interchange of baffle designs. For safety, …

High Power Rocket Motor Test Bench, Jonathan Wine

Honors Theses

Static ground testing of rocket motors is used to gather performance data and troubleshoot the propulsion system, allowing propulsion engineers to compare actual characteristics to the designed parameters. It is also used in the development and validation of new propulsion systems and alterations to the fuel and oxidizer mixtures. Test benches are used to continuously collect data throughout the burn of a rocket motor, which allows engineers to plot the thrust as a function of time. This plot, a thrust curve, displays several important pieces of information about a rocket motor. This information is crucial to allow astronautical engineers to …
