CSU Nutrition Clean Bean Routine

Project ID: 15

Students:

Seth Butler and Muhamad Nugroho
Dry beans or pulses are an important source of protein for many across the world. The beans also provide a source of income for several farmers around the world as well. The issue that arises from growing beans is the cleaning of the beans on a small scale. Often, farmers will sell the beans to large elevator companies who will clean the beans for the farmers instead. This often excludes niche cultivars of beans that the elevator companies are not equipped to handle. The proposed solution by Dr. Thompson and the clean bean team is a small compact device that can be utilized by small-scale farmers to clean these niche cultivars of beans while maximizing profit for these farmers as the middleman of the elevator company is cut out. The device will have to conform to the constraint of fitting within a 4’x6’ pickup truck, being able to be picked up and transported by a minimum of two people, and be one cohesive design meaning all subsystems will work in conjunction with one another instead of being separate. The subsystem will consist of a wind screen and a gravity table. The wind screen will separate by size and will feed into the gravity table which will sort by density resulting in uniform bean population

Project ID: 2

Students:

Nick Bauchat, Riley Duffens, Brad Golgart, Troy Hayes, Andrew LiPuma, Mason Martinez, Sean McGalliard, Lucie Meeker-Gordon, Jules Schimmels, and Parker Sherry
The Colorado State University Ram Launch Initiative competed in the 2023-2024 NASA University Student Launch Initiative competition. Throughout the duration of the project, the team utilized the NASA design lifecycle to design, build, and launch a vehicle to between 4,000 and 6,000 feet. This lifecycle included writing a Request for Proposal, Preliminary Design Review, Critical Design Review, and Flight Readiness Review. Each of the milestones ended in a presentation to a panel of NASA engineers. The purpose of the launch vehicle was to transport and deploy an atmosphere independent lander on descent at 400 feet. The lander's primary mission was to safely transport four human analogues from the drop point of 400 feet to the ground while maintaining human survivability metrics. It was designed to operate with a cold-gas thruster to slow the descent and an inflatable airbag that increased the drag and provided stability for the lander. The launch vehicle was designed around the dimensions of the lander to maintain a safe stability margin for the launch. A subscale launch vehicle was built to validate the material selection and manufacturing processes used. The results of the subscale, both build and flight, were used to inform the final decisions of the full-scale launch vehicle. The project ended with the launch vehicle sustaining catastrophic damage on the final flight. The project resulted with the team developing important soft skills that will be invaluable as they move forward in their careers and forwarding the aerospace industry.

Diesel Exhaust Electric Heater

Project ID: 12

Students:

Charles Ames, Jacob Carnes, Sasha Koulinkovitch, Aidan Taff
  Emission regulations for diesel engines have become stricter over time. To comply with regulations, diesel engines are equipped with an after-treatment system in the exhaust to reduce the quantity and alter the composition of pollutants. This project focuses on the SCR (selective catalytic reduction) catalyst . This component of the aftertreatment system converts poisonous, highly reactive NOx (nitrogen oxides) to N2 and H₂O at high efficiency when the catalyst is above 200°C. John Deere has challenged the team to develop an electric heating system to reduce the time required for the catalyst to reach operating temperatures during cold start conditions as well as to maintain operating temperature during low load conditions. The team designed an electric heater assembly composed of 4 grid heaters that use ~4.8kW to superheat the exhaust flow upstream of the catalyst.

End-of-Line Test Stand

Project ID: 20

Students:

Justin Petterle, Zachary Jones, Kihiro Lambert, Cooper Johnson, Taylor Thomas
Walker Manufacturing seeks to optimize the process of synchronizing their left and right lawn mower wheels to enhance safety, accuracy, precision, and manufacturing efficiency. To achieve this, they have requested the design and fabrication of a custom test stand to go at the end of their assembly line. This test stand acts as a chassis dynamometer, allowing the mower wheels to spin on rollers while the chassis stays stationary. It has been designed to fit the range of lawn mowers that Walker Manufacturing produces. The left and right rollers spin independent of each other, and display their rotational speed while the mower is in drive. The operator will be able to see the revolutions per minute of each wheel while the mower is operating on the test stand. Using the data being displayed, the operator will adjust the control arms of each wheel in real time to account for inconsistencies. This test stand allows employees to synchronize mower wheels stationarily, and while being off of the vehicle. This contributes to overall operator safety, numerically accurate synchronization, and consistency between products.

Project ID: 4

Students:

Kevin Abbott, Panchalika Arphamongkol, Blake Beecher, Tim Rutter, Jared Turner
The low pressure-high flow hydrogen relief valve is a pressure relieving safety device built specifically for the hydrogen electrolyzer industry. As the green energy sector continues to grow, the electrolyzer continues to show promise as the future of truly green energy. The relief device started as a set of broad guidelines from a large company in the energy sector and was built from the ground up. The device is designed to fully open at 165 mbar (2.39 psi) while flowing over 4,500 cubic meters per hour of hydrogen. The device utilizes a custom spring, built in house, as well as internal components designed through the extensive use of CFD. These give the valve the ability fully open at such low pressures. In it’s current form, the device is constructed entirely from machined aluminum, but a production model will be constructed from stainless steel. In order to rapidly change and test several variations of internal components, these pieces were constructed using additive manufacturing. This valve is a lifesaving piece of equipment that will allow the green energy sector to thrive. To our knowledge, there is not currently another valve on the market that can operate under such extreme constraints.
