This year’s HPV project is being done in conjunction with a Senior Project. As such, we are following the scheduling guidelines laid out in the senior project framework.


Research and Design

Frame, drivetrain and rear fairing design concept

Frame, drivetrain and rear fairing design concept

This project is going to be unlike any other we have attempted, and we want to be as well informed as possible to maximize our success. We spent the Summer of 2018 compiling research for the upcoming year, studying principles of fluids dynamics, using online resources, and looking at other teams successful bikes.

The team divided into sub-teams at the end of Spring quarter and research began shortly after. We began to create preliminary designs and integrate our subsystems to create a plan for the year. The Summer research culminated in a trip to Battle Mountain to spectate the 2018 WHPSC and learn how other teams had designed their bikes.

Once school began again, we hit the ground running with an army of new recruits. We continued iterating fairing design, creating our initial mock-ups and running them through our computational fluid dynamic analysis. After the frame’s underlying structure was finalized, other subsystems began to integrate their designs into the frame.

We formally finalized our design at our critical design review at the beginning of Cal Poly’s 2019 Winter quarter. The design included a front-driven bike with a removable steel-frame. The frame will house all of our components except the camera system. The drivetrain will feature a double reduction system to produce larger gear ratios.


Build

This is what HPV is all about - getting our hands dirty and building our bike. The building and manufacturing phase of our project commenced at the start of our Winter quarter.

During the previous quarter, we taught new members manufacturing principles during our learning days. We recently introduced the team to carbon fiber and composite work, and plan to hold more days for metal work soon, stay tuned!

Frame Work - Keyanna Henderson uses an angle grinder to miter a steel tube for our frame jig.

We built up our high density precision board block and sent it to Safran to be CNC’d to the shape of our fairing. We layered fiberglass and carbon-fiber on the foam molds to create our fairing.

As the fairing came together, we also built our interior frame. The frame was made from steel tubes welded together using a gas tungsten arc welding process. Advanced Tubing bent our tubes for us.

The drivetrain and fairing are mounted to the frame along with our various other components. The front half of the fairing is strapped to the rest of the vehicle and can be removed for rapid entrance and exit.

Be sure to get your red tag/yellow tag if you want to help out, it’s not required for a lot of what we do, but it’s still very helpful to have them! Check the Cal Poly machine shop web page for more details on red tags and yellow tags.


Test

Rider Josh Gieschen test rides the frame while project manager Michael Juri tunes the bike to his preferences.

Testing will done over the Summer of 2019. We will be fine tuning, troubleshooting any design or manufacturing errors, and evaluating our rider’s performance on the bike. Adequate testing of the bike is crucial to avoid catastrophic failure at the competition.

Testing will also help us practice for the real runs in Battle Mountain.
