FDR Success! – Blog #26, 4/24/26

It’s official! Team A.R.C. has completed our Final Design Review (FDR) for the IPPD program, and we couldn’t be prouder of what we’ve accomplished over these past two semesters.

When we set out to tackle the growing problem of low Earth orbit space debris, we knew we needed an innovative approach. Through our custom S.M.A.R.T. (Simulation and Machine-learning Assisted Redesign and Testing) methodology, we successfully replaced traditional trial-and-error with an automated, data-driven design loop. By utilizing Kriging algorithms and rigorous hypersonic simulations, our team converged on an optimal Magnesium chassis with deployable flaps engineered to induce violent shock-shock interference intentionally. Proving that our architecture can capture 64.5 megawatts of heat and spike structural temperatures to 1,555 K during a Mach 20 descent is a massive win for the future of sustainable Design for Demise aerospace engineering.

Of course, this milestone would not have been possible without the support of Honeywell Aerospace Technologies. We also want to extend a massive, heartfelt thank you to our liaison engineers: Joseph McMahan and Caleb Sjoquist. Thank you. We also owe a huge thanks to our Faculty Coach, Dr. Rick Lind, for guiding us every step of the way.

As we hand off our baseline geometries and physical prototypes, we are incredibly excited to see where Honeywell takes this technology next. Here’s to a cleaner orbit and a successful end to an unforgettable project!

Final Deliverables COMPLETE! – Blog #25, 4/17/26

This is the week before FDR! We have finished our FDR Report Draft and should be receiving feedback from our faculty coach, Dr. Lind, soon!

Two of the sides for the final prototype were CNCed, and then some of the grinding of the flap angles was done. Only two of the sides remain, and Ben and Zach are going to go back and finish it up tonight!

Looking ahead, we plan on integrating the final prototype chassis with the electronics on Monday and preparing for the FDR event on Tuesday at 1:00 PM! Besides that, we have finalized the video and poster from the feedback we received, so we should be successful for next Tuesday!

Final Deliverables in Progress… – Blog #24, 4/10/26

This week, our team shifted focus toward final deliverables as the project approaches completion. We finished the first draft versions of both our project video and poster, along with a full draft of the Final Design Report (FDR). These milestones mark a major step toward wrapping up the project and preparing for final presentations.

Looking ahead, we plan to continue refining the internal chassis with a fourth iteration while also moving forward with CNC machining and assembly of the metal body prototype. Additionally, we will revise and improve our video/poster based on peer feedback and continue preparing for the FDR presentation.

With all major components coming together, the project remains on schedule as we finalize both the physical prototype and supporting deliverables.

Our second PID! – Blog #23, 4/3/26

This week, we participated in Prototype Inspection Day (PID), where we presented our design and prototype to faculty and industry peers. A key takeaway was the need to better communicate the purpose of our project, specifically emphasizing that our system is designed to fail safely during re-entry and clearly connecting our simulations to the physical prototype.

On the technical side, we completed the fourth and final rounds of both ANSYS Fluent and vibrational simulations, giving us a complete dataset to support our design. We also printed and tested the internal chassis version 2, allowing us to evaluate and prepare for further design improvements.

Next week, we will iterate to chassis version 3, begin CNC machining of the metal body, and continue working on final deliverables, including the video, poster, and Final Design Report (FDR).

Overall, the project remains on schedule as we move into final refinement and assembly.

Oh yeah, it’s all coming together… – Blog #22, 3/27/26

This week, we are getting ready for the PID. Machining, 3D prints, and electronics systems are all completed, and now we just need to put everything together. PID is next Tuesday, so we’ll be assembling our build and finalizing our presentation this weekend!

Our ANSYS runs are all complete, so the modeling team is right there at the finish line with the prototyping team.

It’s been a long process, but everything is finally coming together!

Run, ANSYS, run! – Blog #21, 3/13/26

This week, our team continued to make strong progress on both the simulation work and the preparation for the physical prototype. We completed the second round of vibrational testing and ANSYS Fluent simulations. These additional simulation datasets help further validate our design and provide more insight into the structural and thermal behavior of our system.

On the manufacturing side, we finalized and sent the manufacturing plans for the body of the prototype to the waterjet. This marks an important step toward producing the physical prototype and transitioning from purely simulation-based work to fabrication.

We also completed the initial outline for our Final Design Report (FDR). Establishing this structure will now help streamline the writing process as additional simulation results and prototype data become available.

Looking ahead, the PCB arrived on March 12 and will be assembled in the coming week. We also plan to complete the third round of vibration and Fluent simulations after spring break while continuing to expand the FDR.

The PCB has arrived!

The project remains on schedule as we move closer to prototype assembly and final validation of our design.

What’s the cost (function)? – Blog #20, 3/6/26

This week, our team made significant progress in both simulation analysis and prototype preparation. One of our major milestones was completing the PCB design and placing the order. The board was designed in Altium Designer and represents the electronic system that will deploy our flaps, the board will be 4×4 inches. The board is expected to arrive next week, allowing us to begin integrating the finalized electrical hardware into our system.

On the analysis side, we completed our first round of vibrational testing using ANSYS. The results from these simulations allowed us to finalize our cost function and evaluate the performance of our initial design runs. These results will guide further iterations as we continue refining the design.

We also began coordinating with the lab machinist to plan the manufacturing process for our prototype. Initial waterjet cutting and CNC machining steps were discussed to ensure smooth fabrication once the design is finalized.

Next week, our focus will be on completing the second and third datasets for both ANSYS Fluent and vibrational analysis. We will also begin generating the CAM files needed for CNC machining of the prototype components.

Good Vibes All Around – Blog #19, 2/27/26

Week seven was a strong progress week for our team. We successfully integrated the servos into our electrical system, enabling us to move toward full system functionality and coordination between mechanical actuation and control.

We also presented QRB2, which helped us refine our design decisions and clearly communicate our progress in analysis and next steps. The feedback from this review will guide our final prototype planning.

On the analysis side, we ran vibrational testing in ANSYS to compare natural frequencies and validate our structural behavior. We are continuing to complete the second dataset for both ANSYS Fluent and SOLIDWORKS vibrational simulations.

Looking ahead, we plan to finalize the PCB by Monday, establish clear success metrics for our demisable prototype demonstration, and solidify the manufacturing plan for our final prototype.

Overall, week seven focused on integration, validation, and setting the foundation for final prototype development.

It’s Alive!!! – Blog #18, 2/20/26

We have been steadily working on each part of our project and are working on coming together to join the pieces.

One big piece of progress that we made is that we have fully integrated the electronics system and have verified that every part is operating as we have predicted. Additionally, we have some preliminary code that activates our servo motors when the temperature sensors heat up. This is great news for our prototyping team, as this is a major hurdle that we have overcome, and now we can make and order the PCB! In terms of our thermo-display, that is what the first picture above is showing. We have 3D printed out smaller models of our idea (left) and the existing housing based on the Honeywell MIMU (right). The next step would be molding the plastic on it and doing more testing.

For our ANSYS team, we have made a SOLIDWORKS model that is able to be used for vibration testing, and have finished our first five simulations. The next step is fully defining our cost function and plugging our numbers into the Kriging model to get our next five parameters to test.

We are looking forward to our next steps!

Two Steps Forward, No Steps Back – Blog #17, 2/13/26

We have been making steady progress on our project every week as we move forward on our project plan. Above can be seen one of the large strides that we made on the prototyping team, fleshing out exactly how we can integrate our system in a realistic way. We came up with the idea of using self torquing hinges like are used in self closing cabinets. The hinge will apply a torque to itself with the spring when in the closed position and will be held closed with some fishing line attached to our servo motors. When the motors are told to activate from our sensors and electronics, the slack will allow the hinge to open fully by itself. This solution is a cheap and low tech solution for opening the flaps that should be easy to integrate.

In terms of progress on ANSYS, we have the the of the first five Latin hypercube models made and our SolidWorks model optimized for ANSYS simulations and easy application of the parameters we are given from our Kriging model. We have done this by both simplifying and making the model more accurate, adding in the areas the flaps would be inlaid whilst filleting parts of the model where the air would create problematic areas in our ANSYS simulation. This has allowed us to make a ton of progress in our simulations, and in turn we have gotten our first points of data that seem to be accurate compared to literature values we found.

All in all we have had an extremely productive week and we are very proud of the progress we have made. We are looking forward to making even more in the weeks to come!
