Thank you so much to our generous sponsor, ANSYS, for sharing our project on their blog! Huge thank you also to our Director of Fabrication, Chris Raatz, for writing this post. Feel free to check out their blog post here ---> https://www.ansys-blog.com/embry-riddle-students-crowdfund…/
The Eagle Works Team had an opportunity to document their story like never before in their history. Click on the video to learn about the E-2 land speed vehicle project and how you can help make this dream a reality.
Thank you, NGN Pictures, for your time and helping make this video a possibility
Eagle Works is excited to announce that our crowdfunding page is now live! Support us in our effort to break the E-2 land speed record for electric vehicles. Thank you to all of our current sponsors and donors for helping lead the future in clean technology. Eagle Works appreciates your continued support and enthusiasm for this incredible project. Our crowdfunding page can be accessed at the link below or the donate button on our Facebook page!
Stay tuned Eagle Works fans and followers as we anticipate the final aeroshell design. This key component of the car not only protects the internal systems of the car but it is also critical for stability at high speeds. The aerodynamics team has been hard at work refining and optimizing the model. We look forward to the final product!
We would also like to thank ANSYS for all the help they have given us to do analysis on not only this crucial component but many others as well.
With 70% of the car components modeled in CAD, the team dedicated Saturday toward finishing and refining models.
A recently finished CAD model is the completely assembled battery cell with new CCA connectors. Explosively Welded Copper Clad Aluminum connectors (CCA) will connect to the battery cells of the car, allowing a flow of energy through the batteries and powering the vehicle. The CAD models below are essential to the success of the car as they are critical components in the movement of the vehicle. The CCA creates a set of series and parallel connections in the cells, resulting in higher voltage and amperage respectively. The more of both connections that exist, the more power the batteries can distribute and therefore the more energy available for the car.
Below are CAD models for the CCA and battery cell designed by Johnathan Crossley. The third picture is a manufactured CCA.
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.
