JCATI Carbon Fiber Recycler- Fiber Conveyance
Get PDFSponsored by the Joint Center for Aerospace Technology Innovation (JCATI), this project stems from a partnership between Central Washington University’s Mechanical Engineering Technology program and The Boeing Company. The goal of this partnership was to create a device that repurposes carbon fiber from wing trimmings from the 777. The device features four different students’ projects including the crusher, shredder, oven heating system, and the fiber conveyance system; the focus of this project. The JCATI Carbon Fiber Recycler needed a device to transport material from the shredder to the oven to make for an easier, more seamless production process. To solve this problem, a conveyance system was designed, manufactured, and tested at CWU. Requirements were set prior to the design phase such as speed, weight limit, belt tension, at least 90% of material is conveyed from point A to point B, etc. Using these, analyses were performed using engineering methods such as statics, belt tension/torque calculations, and bearing size/belt length calculations to determine dimensions. A design was put together using SolidWorks. This design was then executed using purchased parts or manufacturing parts in the CWU machine shop. Most parts were purchased online such as the bearings, pulleys, and motor. A few parts that were manufactured was the frame, tensioner, and couplings. The project was a success; the conveyance system was successful at transporting carbon fiber. The speed was 0.98 ft/min, the weight was 23 lb., the belt withstood 6 lb. of tension, and 98% of the carbon fiber was successfully transported
NASA Student Rocket Launch
Get PDFThe Rocketry Payload team consisting of Kallysta, Eli and Ethan needed to build a payload that flew in a rocket also built by the team. After the rocket has landed, a camera is deployed outside the rocket through a 3-inch gap created by a linear actuator. The camera must rotate 360 degrees and take photos of the surrounding area. The entire system must weigh less than 4.4 pounds as well. The team designed this system using their knowledge obtained through the Mechanical Engineering program at Central Washington University. It was important for them to keep in mind that the system also needed to be structurally strong enough to survive a rocket flight 5000 feet up as well as an impact upon landing. Under these circumstances, material and design were very important so that the payload could be strong enough to survive the flight. The final launch being held in Huntsville, Alabama was a success. Once the rocket landed after launch, the system used a linear actuator to create a 3-inch gap for the camera to deploy out of. A spring then pushed the camera and motor upwards allowing for an exterior view of the surrounding area. The camera was then able to rotate 360 degrees to take any pictures necessary that NASA has sent to the system. The final payload weight was also 4 pounds, staying under the requirement
Jack & Alex RC Baja
Get PDFThere are paramount necessities to build an RC car such as the steering and suspension. Without either, the vehicle will not be able to ascertain basic movement characteristics. The team will compete in the RC Baja competition with the other students which will have various challenges and obstacles that they will endure. The device must be able to complete tests that will prove competence for the competition. By using knowledge of prior classes and experience, the team will produce a functional device for the event. Mechanics of materials and statics were used to determine the bending strength of the control arms and the tensile strength of the shock towers. The shock tower and control arms were the largest manufactured parts of the project. The purchased parts include shock springs, steering servo, steering pin, and threaded rod. First the results of the project were separated into three sections, the design, construction, and testing of the device to the specified requirements. Second was the construction phase, which meant that the team was ready to start the fabrication process of the device. Third was the testing of the project. The other engineer in the project oversaw chassis and drivetrain. As a result of the design, the shock spring will only compress 30% when dropped from two feet which will be done in the testing phase
JCATI Carbon Fiber Recycler: Crusher System
Get PDFWith a substantial rise in Carbon Fiber use across all industries, the need for a way to recycle the waste has grown as well. A group of Mechanical Engineering Technology students at Central Washington University funded by the Joint Center for Aerospace Technology (JCATI) have created a machine to recycle waste wing trimmings from the Boeing company’s airplanes. This machine consists of 5 different sub-assemblies being the oven, crusher, gear train, conveyor, and shredder. The purpose of this project was to decrease the deflection in the crusher caused by bulging in the housing and movement of the bearings. To decrease the deflection in the two areas a new frame and housing was manufactured to allow room for the CWU machined bearing blocks and bracing. Bearing blocks allow for adjustability of the shaft position and locks them in place. The driving factor for the addition of bearing blocks is the 9000-pound shear modulus of the carbon fiber which causes the previous crusher to spread apart. To ensure the design changes would stiffen the machine and not deflect statistics was used to analyze each piece as a beam. Once the machine was completed it was found that the shafts did not deflect more than five hundredths of an inch, the total deflection was three hundredths of an inch. Additionally, the housing when operating deflects four hundredths of an inch which is less than the max of .0625 inches allowed. The machine now reliably recycles the wing trimmings and produces raw carbon fiber
RC Baja: Suspension and Steering
Get PDFEngineering students attending Central Washington University were tasked with developing and creating a functional RC car. This car would then compete in a state-wide competition while being developed over the course of three quarters with the competition being held in the spring. This was completed in teams of two that were assigned two of the four sections within this project who then independently designed and developed each section. This was broken down into having one teammate in charge of the drivetrain and chassis and having the other teammate working on the suspension and steering sections of the vehicle. Each section required several design analyses to ensure the vehicle was both functional and operable within the requirements set by each team member. The expected outcome of this project tested both students’ ability to think critically in a team setting, as well as test their engineering knowledge and their ability to design and plan out each independent section of the car. The outcome of this project accomplished the requirements set which accumulated with the engineering team completing all sections of the RC Baja car. This was aided by the design and testing phase, which saw that the vehicle would perform within the parameters set by the engineering team. For example, the vehicle was found to be able to withstand drops 100% higher than the two-foot drop requirement. This also allowed the team to compete in the RC Baja competition where they completed each course of the race and represented CWU’s engineering degree
