Happy 2018! The team hit the ground running today, picking up where we left off in the fall. Be sure to check our Facebook page, website, and Instagram for weekly updates and notifications about our mission to beat the E-2 land speed record.
Previously, the aero shell design has fulfilled an optimization of the nose tip height, relative to the maximum height of the nose; ANSYS Fluent was used to analyze the turbulent flow about 21 CAD models differing only in nose tip height. It was found through quadratic regression analysis that the optimal nose tip height (for minimum drag values) would be 28.9% of the maximum nose height. Currently, 4 CAD model assemblies have been generated to study the flow entering the wheel wells of the vehicle, with CFD analysis planned for Saturday, November 18. The first two models examine whether changing the edge leading into the wheel wells from sharp to rounded would effect the flow entrainment into the wheel wells; the second two models look into adding extra devices and their impact upon the aforementioned flow entrainment. After the wheel well flow entrainment has been minimalized, there are three more optimization studies that will be conducted by the end of the semester: (1) the flow exit from the wheel wells will be optimized for minimal drag and maximum downforce, including wheel well louvres and top-mounted, horizontal ducts; (2) the design of the canopy and driver ventilation, will be optimized for minimal drag and size; and (3) the general shaping of the entire vehicle will be refined by adding varying degrees of camber and edge filleting.

Today Eagle Works team members met to take team photos for Fall 2017. As team members waited for the photographer, members discussed the current progress of systems, as well as the overall progress of the vehicle. As the team prepares for the upcoming Thanksgiving Break, be sure to check out our website and Facebook to see new pictures of the team!
As team members complete computer aided design (CAD) models of their respective subsystems the big picture of the vehicle's internal components is coming together in real time. Computer modeling of the vehicle is a crucial step in the design process. A design flaw encountered in the CAD stage can be more easily and effectively corrected than in the heavily anticipated fabrication phase.
Recent completed models include the brake master cylinder, rear disk brake and parachute test frame. The brake master cylinder and disk brake will be added to the CAD model of the complete vehicle to ensure that they fit properly into the vehicle as a whole. In the same subsystem a frame for the parachute is underway in preparation for parachute testing. More bits and pieces are on the way and as each one is completed the Eagle Works dream gets closer and closer to a reality.
The Eagle Works Team would like to thank the brave men and women who serve to protect the freedoms we enjoy everyday. We express special gratitude to our own team members that have taken up that role. We wish a happy Veterans day to all.
Several members attended Prescott's Electric Vehicle Association's meeting to help promote electric vehicle usage. Both organizations believe in increasing the support and use of electric vehicles (EV). Members from both organizations collaborated on dates for future events, and kept updated on current news about the EV industry. Eagle Works is looking forward to working with the Prescott Electric Vehicle Association in the future, and helping to lead the future of EV's in the Prescott area and State of Arizona. For more information on the Prescott Electric Vehicle Association or how you can help support the future of transportation, see their Facebook group here.

Today during the Open House hundreds of visitors and prospective students experienced what the ERAU Prescott Campus has to offer, including a typical workday for the Eagle Works team. While most members continued work on their systems, other members gave tours of the workshop. Visitors were able to observe team member cooperation and production firsthand. Seen below is team President Reece Ticotin speaking to a group of visitors, accompanied by Chancellor Ayers.
Eagle Works moves into fall semester with a productive start. New members are growing accustomed to the engaging and fast-paced atmosphere of weekly work sessions, and their engagement is appreciated.
With a finish date before Speed Week in the summer of 2018, the team’s focus transitions from concept to construction. A 3D model for the car’s structure and cooling systems have been conpleted using CAD software, and more are to follow. Members in the shop proceeded to organize the shop area in preparation for fabrication. Other members continued research efforts to find the most efficient and reliable products to use on the vehicle. Only halfway through the fall semester, and already the car is speeding toward completion.
Below is the CAD model of the frame, batteries, and front-end suspension designed by members Alex Benz, Nate DePutter, Christopher Raatz, and Reece Ticotin.
The past few weeks have been full of back to back action for the Eagle Works Team. Members that have been away were brought up to speed on the hard work the interns had been putting in all summer. From there the Team dove into recruitment and selected the best of the best that Embry-Riddle Prescott Campus has to offer. The day these new members were brought on board they were put to work; their energy and excitement for the project on that day has already been felt by the rest of the team.
With the new team members came a new team structure, designed by team member Alex Chambers. The goal is to keep each team member more accountable for their part of the project. The team is using simple and efficient engineering management software to help them track the progress of each system. The benefits are already paying off after only a few weeks of implementation.
The Eagle Works Team has no intentions of slowing down.
Before the Eagle Works Team began gearing up for the academic year the Eagle Works summer interns were hard at work making as much progress as possible before heavy class loads became an obstacle.
Below is the design for the front end by Alex Benz, who worked tirelessly over summer to bring this piece of the car to life. The two motors will be encased by a custom machined aluminium block. A brilliant over-under cooling system will be used to keep the motors from overheating. During Speed Week the team learned that the Salt Flats aren't very flat at all. With that in mind heavy duty off road suspension parts will be used to keep the car from bouncing violently on race day. One last fun fact, Corvette hubs turned out to be a perfect fit to mount the wheels! There's nothing like classic American muscle even on cunning edge of new age technology.
This summer, six members of Eagle Works got the opportunity to work on the Land Speed Record project full time as Interns, surging the team's progress forward. While much was learned over the three month break, the biggest takeaway for the team was a three day trip to the Bonneville Salt Flats for the 69th annual Speed Week. During the trip our team gained an immense amount of knowledge from the Salt Flat's Veterans, and came up with many great ideas for the project. Those ideas will be implemented throughout this coming semester, which starts Monday, August 28th. The team is looking forward to getting back to work, and making great progress this semester! If you are interested in joining the team, come visit our booth at the activity fair on September 7th, or contact Reece Ticotin at firstname.lastname@example.org.
