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.
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.
Meet our newest members!

They are all very excited to contribute their talents and determined to help bring our project to fruition.
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.
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

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!

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.

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!
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!
To build this car it takes a team and that team needs excellent leadership. Have a chat with our preseident, Reece Ticotin.
The Eagle Works Team is proud to announce that two of their members were recognized at Embry-Riddle Prescott's Women of Excellence Banquet this past Thursday evening. Julia Mihaylov received The Outstanding Woman of the College of Engineering Award and Maelee DeVries a prestigious scholarship. Both of these amazing ladies give their all on and off the Team.
Beyond Julia's duties to Eagle Works as the telemetry lead, cooling lead and Team secretary, she serves as the Editor in Chief for Horizons, the ERAU Prescott newspaper. The list of responsibilities does not stop there for Julia as she maintains a high GPA, has worked with JPL on a coding research project and is an active member of Alpha Xi Delta.
Maelee pours hours into the E-2 car's battery system, but the interesting thing is that she is actually a forensic biology major. The Team is lucky that Maelee has a fascination with engineering. Outside of Eagle Works MaeLee works on Project Pengyou, an organization that promotes cross cultural relationships. As a freshman she has been offered teaching assistant positions within ERAU Prescott's chemistry department.
Thank you ladies for all you do for the Eagle Works Team and congratulations on your incredible achievements!
