The purpose of the device will allow U.S. Air Force Academy Cadets to learn about data recording on their flight systems and general avionics. Southwest Research Institute Aerospace Structures Section has commissioned this effort to be designed and built by a UTSA Senior Mechanical Engineering Design Team. The device operates with two Raspberry Pi-based computers and has an accelerometer, pressure transducers, a strain gauge, and a thermocouple. The input computer controls the mechanical systems to simulate various flight profiles with varying flight parameters and the output computer records the resulting flight profile data. The device will measure altitude, airspeed, acceleration, aerothermodynamic properties, and structural fatigue data from the given flight input parameters.

A.L.L.I.E. - Automated Liquid Loading with Intelligent Execution | Automated Liquid Loading with Intelligent Execution, or "ALLIE" for short, was created with the goal of automating the process of filling oral syringes. ALLIE aims to fulfill the tasks of transporting, filling, capping, labeling, and batching the oral syringes, allowing pharmacy technicians to delegate time otherwise spent on preparing prefills to more important responsibilities. ALLIE strives to accommodate varying types of oral medicine as well as varying sizes of oral syringes in an efficient manner, delivering punctuality without sacrificing flexibility. For this capstone project, the scope was limited to the subsystems involved in the filling, capping and transporting processes for 3mL syringes.

Lightweight Lunar Vehicle | The proposed project aims to create a light-weight lunar spacecraft capable of operating at the client's requested performance while minimizing superfluous bulk. Sensors must also be installed to provide adequate performance data for motor tuning. To do this, rover platforms will be designed and analyzed to sustain the lunar vehicle while safeguarding sensitive electronics from simulated regolith. The most prominent solution will prioritize performance and mass efficiency while also being cost effective when selecting base materials, being maneuverable for zero radius turns, durable enough to ensure the safety of the motors and sensors, providing adequate driving force to maximize payload relocation, and output performance data to aid with simulations.

Heat Resilient Surveillance System | Heat-Safe Engineering is commissioned to engineer an advanced second-generation modular camera housing assembly. This unit is designed for high-temperature applications, including combustion chambers, reactors, incinerators, and furnaces. The objective is to augment SwRI's capability to provide clients with a vivid, real-time visual inspection of furnace interiors, thereby enhancing data presentation with superior visual interpretation. As the project progresses into its advanced phase, advanced cooling methodologies, including pneumatic cooling systems, will be evaluated and implemented to mitigate extreme thermal conditions.

C-17 Stacker | To address concerns about the functionality of the C-17's ability to carry people and cargo, our team is developing the C-17 Stacker in conjunction with Knight Aerospace. The C-17 is a large cargo aircraft commonly used in the transportation of oversized products. However, on occasion, the C-17 has been used to transport people for evacuations or rapid mobilizations of military personnel. To optimize the mission functionality of C-17s, our project will take advantage of the overhead dead space commonly available during the transportation of cargo by using an elevated pallet system that will roughly double the amount of personnel that can be transported.

Chicken Seasoning Machine | Due to multiple issues with a flour dispenser repurposed for seasoning chicken including high setup and maintenance times, seasoning waste, imprecise amounts of seasoning applied, and more, the client is requesting a new machine for seasoning chicken. The Chicken Seasoning Machine, or CSM, is the proposed design to solve those issues. It actuates a flip via an inclined conveyer system and by controlling the speed of a screw feeder mechanism loaded with seasoning that is set to run upon detection of chicken via infrared sensors, the machine can deliver precise amounts of seasoning.

The Good Shepherd | The Good Shepherd Senior Design team has designed a dual frequency ultrasonic device. This device's intended purpose is to assist in the herding of livestock such as cattle and sheep through acoustic motivation. The device is powered by a standard ATV lead acid battery and can be mounted onto a standard ATV rifle rack. Dual ultrasonic frequencies have been chosen to create a unique sound for livestock to react to, that is outside the standard hearing range for humans. The group is pursuing IP protection and to present the device for commercialization. This project is sponsored by Dr. Keith Axler and the UTSA Mechanical Engineering Dept.

Fully automatic tourniquet attachment | This project focuses on developing a prototype device in collaboration with the United States Army Institute of Surgical Research to automate the application of windlass-style tourniquets. The aim is to address issues related to consistency and device stability by creating a system that can be easily attached to an existing tourniquet. For the mechanical aspect, the primary goal is to integrate a functioning stepper motor and design an enclosure that securely attaches to the tourniquet. On the electrical side, the focus is on developing a reliable pulse sensor that monitors the user's BPM and displays the data on a screen. The motor will automatically stop and maintain tension when the pulse sensor detects zero BPM, ensuring the tourniquet remains tightened. A critical component of the design is connecting the motor to the pulse sensor for synchronized operation. Both the mechanical and electrical components, including their enclosures, are designed for use on upper body extremities.

G.A.U.R.D.N.E.R. | Team AERO ADVANCEMENTS has been assigned to design a mobile and effective aerial vegetation distribution system. The intent is to use techniques in precision aerial distribution to better re-forest remote and inhospitable locations. The task team assignment may be later extended to better develop the device into a viable and profitable product. This could form a new evolution in environmental conservationism and peaceful use of military technologies.

Brisket Shredder | The project proposed by H-E-B Fresh Plant aims to enhance a recently acquired used shredder machine, with the goal of processing brisket more quickly than the current slicer. The existing machine is time-consuming, relies heavily on manual labor. The new shredder is expected to streamline the process, but it requires improvements. To address this, Group PASS has proposed the design and addition of an inclined conveyor belt to boost efficiency and protect the operator. Additionally, emergency sensors and a variable frequency drive have been incorporated to ensure the machine's safety and enable control of the shredder's speed.

Duplex/Caster Tire Tester | Continental is developing a multi-axle test trailer for gravel road testing that enables individual load control per tire pair and allows different tire sizes on a single rig. This is part of a larger project. The previous duplex/caster unit needs redesigning to enhance stability. The wheel ends should be shifted outward to lower the load basket closer to the ground. Additionally, the basket's dimensions must be adjusted to accommodate steel ballast weights up to 4,500 lbs. Ideally, two units should run side by side within a 13-foot lane.
