Jack And Alex Rc-Baja, Alex Vornbrock

All Undergraduate Projects

Teams of two mechanical engineering students were tasked with the construction of an RC Baja car qualified by the rules and regulations of the Baja competition as well as specifications set by the individual team member for their portion of the vehicle. This proposal focuses on the Chassis and Drivetrain of the vehicle while team member Jack Stutz oversaw the steering and suspension. Teams will compete against each other in various modes to determine the best vehicles of the competitors. The chassis was made of standard aluminum, the remaining parts made by the students were made with PLA; both materials …

Jcati Carbon Fiber Recycler: Oven Enclosure, Margarita Romero

All Undergraduate Projects

Central Washington University partners with Boeing and is funded by the Joint Center of Aerospace Technology Innovation (JCATI) to develop a mechanism that takes carbon fiber wing trimmings from Boeing that are resin coated and recycles carbon fiber. This is done by crushing the wing trimmings and then putting it into a 500°C oven to melt off the resin. This project focuses on the enclosure for the oven and making sure precautions are met such as having the outside surface be less than 45c through heat transfer analysis, argon fills enclosure in 13 minutes through fluid dynamics analysis, and 99% …

Forge Burner, Caleb Desjardins

All Undergraduate Projects

Can small scale blacksmithing operations achieve a level of efficiency in their forge comparable to that of a large scale industry? The causes for the lack of efficiency needed to be pinpointed, and then the geometry of the existing design for the burner could be changed to fix the underlying issues, while still maintaining functionality. The problems with the previous design is the geometry of the intake giving an unknown air/fuel ratio, and the attachment of to the forge allowing the intake air to be contaminated by exhaust gasses. A burner needed to be designed that would solve these problems …

Carbon Fiber Recycler : Fiber Reclaimer, Alexander Edwards

All Undergraduate Projects

Boeing uses composite components for the 777x aircraft. The production of composite parts results in flashing (excess material) that must be trimmed and "thrown away" as scrap. Boeing is investigating means of recycling these scraps. The method proposed for this project is to delaminate and shred the composite material. The delamination process uses a ram to press two claw shaped devices together that bends and deforms the material in opposite directions. The chipper process uses counter rotating saw blades spaced 1/8” apart to produce small shredded material. This shredding material is pyrolyzed (heated) to decay the resin leaving the carbon …

On-Demand Water Heater (for homebrewing systems)

By Jason Warenski (Engineering Technologies)

The on-demand water heater is being built for a home brewing system. The is intended to improve brewing process efficiency while reducing the footprint of the brewing equipment. The device contains a coil made from 3/8” soft copper tubing. The coil is inserted into a housing which is constructed of two 22-gauge stainless steel cylinders and a layer of ceramic insulation. Attached to the inlet and outlet of the coil are monitoring and control devices. On the inlet is a water flow meter which allows the user to monitor …
