Batteries Update

Testing for the batteries started today! We checked multiple facets of running a single module, which contains twenty-four lithium, iron phosphate batteries. These checks included thermal, voltage, and amperage tests. Here are some of the pictures we took while the tests commenced.

Fabrication Update

Check out the Fab team working on the metal frame of our vehicle. Each member is in charge of notching and prepping the parts of the frame for welding. They have successfully notched all the metal tubes to 90 degrees and have completed the base floor. The team plans to finish notching the midsection and begin the welding process by next month.

Aeroshell Team Update

The aeroshell team, lead by Mason Mckovich, is hard at work analyzing various factors that impact the stability and speed of the car. They are currently focused on validating the parachute's computational fluid dynamic analysis; this includes confirming the MatLab code, designed to calculate the values of drag on the parachute, and verifying there is sufficient airflow to allow the parachute to decelerate the car once deployed. Pictured below is the parachute.

Drag chute Pseudo Test

Parachute lead engineer Phil Elterman assisted by aeroshell engineer Mason McKovich performed a pseudo test of the drag chute this morning after the surprise delivery of the aluminum tube that will be containing the parachute. Of course, this is a small step taken to gain a better understanding of the current parachute system and how it can be improved to ensure safety and consistent functionality.  Enjoy!

Following the run of the Eagle Works land speed car the drag chute will be released by a cable mechanism and pop out just like in the video. The drag chute will catch air and pull the rest of the parachute out of the aluminum container slowing the land speed car before engaging the brake. This method of decreasing velocity is often used in drag racing.

Parachute Test Frame

Mason is not the only Eagle Works summer intern hard at work in ANSYS, Phil Elterman has also spent many hours in ANSYS working with structural analysis to prove a prototype parachute frame for testing purposes. It is crucial that this component is designed well as a parachute will be the main method of slowing the land speed car down before the brake is applied. In the image below you can see the displacement that the test frame will experience under 300 lbs of force. Displacement is measured in inches and the values corresponding to the colors on the image can be found in the upper right hand corner

CAN Bus

This week Eagle Works coder Zach Griswold made significant progress on the car's CAN bus. CAN stands for controller area network, the CAN bus allows each system to communicate with one another and the driver. Zach was able to get two circuit boards to communicate using message buffers and data buffers. Zach was even able to get the messages to send at a rate of 10,000 times per second. Zach plans on using what he designed here to complete the message sending and receiving structure for the CAN bus and be able to write data to SD cards. Keep it up Zach!

Aeroshell Progrss!

This week at Eagle Works the spotlight shines on Mason McKovich as he tirelessly completes CFD studies in ANSYS to optimize the aeroshell of the car. The aeroshell is a crucial component of the land speed vehicle because it not only protects the vehicle's components and driver but it ensures stability and assists with efficiency during driving. Lately Mason has been focusing on the wheel wells to make sure that no huge pressure pockets are forming and that air will run over the tires and through the wheel wells smoothly.

Meet the Summer 2018 Interns!!

The wait is over, meet the Eagle Works Summer 2018 Interns. After a few weeks of a well-deserved rest and relaxation a select few of the Eagle Works Team members are back in the shop working on the project for the summer. In the photo from left to right are Mason McKovich, Phil Elterman, Robbie Konieczny, Zach Griswold, and Sean Rager. This group is looking forward to a lot of milestones this summer. Good luck!

Sci-Tech Festival

Eagle Works spent today at Embry-Riddle Aeronautical University - Prescott Campus along with Prescott Electric Vehicle Association (PEVA) and the Phoenix Electric Auto Association at the Sci-Tech festival. Tesla's, Volts, and our high-speed electric vehicle, there is a lot of energy over here at Embry-Riddle!
