Day 6: A Ray of Success for Principia Solar Car at FSGP

On Thursday evening, Principia Solar Car proudly secured Second Place in the Formula Sun Grand Prix (FSGP), completing an impressive 189 laps without incurring any penalty laps. This marks a significant improvement from last year when the team faced 13 penalties.

Principia’s top competitors were ETS, which clinched First Place with 215 laps, and Illinois State, which finished Third with 149 laps. The competition was fierce, but the camaraderie among teams was even more noteworthy. Principia’s team members enjoyed bonding with other participants, lending a helping hand with various aspects of their cars, and forging lasting friendships.

A unique and memorable event occurred this year that hadn’t happened in over a decade. During each FSGP, team members volunteer as corner workers, serving as vigilant observers on the track. Equipped with blue, yellow, and red flags, these volunteers play a crucial role in maintaining safety. A blue flag signals caution, a yellow flag prohibits passing and advises slowing down, while a red flag, the rarest, commands all drivers to stop immediately.

This year’s track at NCM Motorsports Park featured a challenging section known as the “sinkhole,” a steep downhill followed by an equally steep uphill. On Thursday, at least six cars got stuck near or at the bottom of the sinkhole, blocking the road. Thanks to the quick action of the corner workers, HQ initiated a track-wide stop with the red flags, ensuring the safety of all participants.

Aside from this incident, the weather was favorable, with typical Kentucky winds and minimal cloud cover, allowing the solar cars to perform at their best. On the final day, three additional teams managed to get their solar cars onto the track and complete laps.

Although Principia Solar Car will not be participating in the upcoming Cross Country ASC Race starting in Tennessee, the team extends its support and best wishes to all competing teams. Principia looks forward to future challenges and successes on the solar car racing circuit.

Day 5: “The power of the Sun, in the palm of my hand”

Principia Solar Car continues to shine, ending Day 2 with an impressive 122 laps. The team holds steady in second place, trailing ETS with 141 laps and ahead of Illinois State with 96 laps.

The day was characterized by cloudy skies, rain, and strong winds. With wet roads, all the solar cars decided to slow down for safety. Despite the challenging weather, Principia’s car had no breakdowns, only stopping to pit or wait for more sunlight to emerge from the clouds. The team’s two drivers for the day, Sebastian Kyllonen and Avery Hansen, navigated these conditions with skill and caution.

Notably, five more teams made it onto the track, increasing the competition.

Thursday marks the last day of raycing, and the final report will be posted tonight. Principia Solar Car continues to demonstrate their resilience and expertise in this rayce.

Day 4: Left Turn, Right Turn, Lap after Lap…

Principia Solar Car hit the track on Tuesday morning. Despite the humid conditions, the team had an impressive first day. After the initial day of racing, Principia completed 69 laps, securing second place behind ETS with 76 laps and ahead of Illinois with 44 laps.

Unlike several teams, Principia’s car RAXI (Ra 11) experienced no car malfunctions and only had to pit for driver changes, showcasing their diligent preparation and reliable vehicle performance. Out of 32 teams, only 12 made it onto the track, highlighting the challenging conditions and rigorous competition.

Principia’s performance has qualified them for the American Solar Challenge (ASC), although they will not be participating in the event.

The team remains focused and determined, ready to take on the next two days of racing with the same dedication and spirit that brought them this far.

End of day report will be posted tonight.

Day 3: All systems green! Ready for the Track!

Today marks a significant milestone for the Principia Solar Car team as they successfully completed all phases of scrutineering, finishing 8th out of 32 teams. This accomplishment secures their spot to start 8th on the track. The team tackled minor fixes, including adjusting lights and ensuring one driver passed the wet brake tests, wrapping up the process with ease.

The day began with an 8 AM meeting, followed by a comprehensive track tour for the drivers to familiarize themselves with all the turns and no-passing zones.

To celebrate this achievement, the team enjoyed a well-deserved dinner at Longhorn Steakhouse. However, the journey doesn’t end here. With the track ahead, the team remains committed to continuous preparation and improvement.

Principia Solar Car is now poised for the next phase, eager to showcase their dedication and hard work on the track.

Day 2: Getting Ready for the Track!

The Principia Solar Car team is on the brink of completing the rigorous scrutineering process, with only two stations left to tackle: the Lights Test and the Wet Braking Test. Once these are completed tomorrow, the team will be ready to hit the track on Tuesday, eagerly anticipating the opportunity to start racking up laps.

One of the most notable aspects of this year’s preparation is that the team is not facing any penalty laps, a significant improvement from previous years. This is a testament to the hard work and dedication of everyone involved, ensuring that the car meets all the necessary regulations and standards.

Scrutineering, a comprehensive inspection process, is designed to ensure that all vehicles comply with the safety and technical regulations of the competition. It is a critical phase that every team must pass before being allowed to compete on the track.

The Dynamics section of scrutineering is particularly challenging, comprising four distinct stations, each testing different aspects of the car’s performance and handling:

  1. 180-Degree Turn: The car must successfully execute a 180-degree turn within a specified diameter. This test evaluates the vehicle’s maneuverability and turning radius, crucial for navigating sharp corners and maintaining control during the race.
  2. Figure Eight Course: The team must navigate a figure eight course, aiming to complete each lap consistently in 16 seconds. This test focuses on the car’s ability to maintain speed and stability while changing directions, highlighting the driver’s skill and the vehicle’s balance.
  3. Slalom Course: The car must weave through a series of cones in under 11.5 seconds, twice. This test assesses the vehicle’s agility and precision, requiring quick and accurate steering to avoid knocking over cones.
  4. Wet Brake Test: The car must come to a complete stop within 3 seconds when traveling at approximately 30 mph on a wet surface. This test is crucial for assessing the car’s braking performance and ensuring that it can stop safely under adverse conditions.

Completing these tests successfully is no small feat, and the Principia Solar Car team has demonstrated remarkable progress and skill throughout the scrutineering process. The anticipation is building as the team looks forward to the opening of the track on Tuesday, where they will finally get the chance to showcase their hard work and dedication.

Stay tuned for updates as the Principia Solar Car team embarks on this exciting journey, aiming to achieve new milestones and push the boundaries of solar-powered racing.

Day 1 Done, 5 more to go!

Today marked an exceptional start for Principia Solar Car at scrutineering. Beginning with a comprehensive 9 am all-teams meeting, we covered the essential rules and logistics necessary for a smooth scrutineering process.

Throughout the day, we focused on optimizing our battery capacity and implementing crucial improvements, which have already started to pay off. By the end of the first day, we secured half of the required green stickers needed to qualify for track entry. We received green stickers for Array Testing, Safety, Battery Protection System, and Impound Box. We have yellow stickers for Electrical and Lights & Vision.

The remaining stations we need to clear are Mechanical, Dynamics, Body & Sizing, Driver Operations, and Driver Registration. Dynamics is the final stage before we are allowed on the track. While yellow stickers indicate that Dynamics is permitted, we need all green stickers to get on the track.

Securing this many green stickers on the very first day is a significant achievement for Principia Solar Car. In previous summers, we did not reach this level of compliance so swiftly. This progress reflects our team’s dedication, hard work, and continuous improvement.

Stay tuned for more updates as we continue our journey through scrutineering!

Kentucky, here we are!

Principia Solar Car is ready to start an amazing week of competition. Our group departed from Principia College at around 8:30 AM on Friday, enjoying a peaceful ride down to the NCM Motorsports Park track in Bowling Green, KY. This summer’s events will see 32 teams participating, including some who have traveled all the way from Canada. The track itself is a new and exciting experience for many of the teams.

Upon arrival, our team wasted no time. We quickly offloaded the trailer and got straight to work, focusing on making crucial improvements to our car. Our dedication and teamwork were evident as we worked tirelessly to fine-tune every aspect, ensuring we’re in the best possible shape for the challenges ahead.

Stay tuned for more updates as we progress through the competition. We’re eager to share our journey and achievements with you as we strive for excellence on the track.

IDAHO, HERE WE COME!

First of all—we won! That has to be the lead for this year’s blog. But fear not; you cannot skip the rest of the blog because how we got there is an interesting tale.

More interesting than last year? More interesting than showing up the first day with a trailer full of parts, assembling RA XI on the fly and summiting Raton Pass in the middle of summer with only MIT and University of Kentucky for company?

Yes. Mostly because…………..we won. Now, to be perfectly accurate, clear and humble it must be said that the Principia Solar Car team won the Formula Sun Grand Prix, the qualifying event for the American Solar Challenge (ASC). Today we begin the ASC: a cross-country race re-tracing the path of the historic Oregon Trail. Sadly, (fortunately?) the race does not go all the way to Oregon. But it does get mighty close. Today we begin the cross-country portion of the challenge in Independence, MO, the origin point not only of the Oregon Trail, but the Santa Fe Trail (last year’s route) and the less-well-known California Trail.

For the past week, the team worked very hard to arrive on the first day with a fully-assembled car. Mission accomplished. That proved to be a decisive advantage this year as the car proved itself durable, efficient and…well, we’re still waiting for a small and lightweight air conditioning system for the drivers, but that can be next year’s addition.

With the car more-or-less ready to go from Day One, the big questions were to see how quickly and how many times it could travel around the track at Heartland Motor Speedway in Topeka, KS. As it happened, over three days of racing at Heartland, RAXI logged about 300 laps—which was enough to bypass both MIT (2nd place) and University of Kentucky (3rd place), our old hill-climbing buddies from last year.

The car actually did more than 300 laps but had to take a couple of penalty hits for some minor “scrutineering” issues. The team performed admirably—both inside the car and in the pit. We can’t share many of the technical and strategic factors because a) the race is still on, and b) Team Leader Brian Kamusinga does not “want to let the others know what we’ve got.”

The Formula Sun Grand Prix win puts Principia at Pole Position #1 in the Single Occupant Vehicles (SOVs) category which is the class we race in. That will be another advantage for the cross-country trials, and the team plans to make the best of it.

Stay tuned to this blog to hear more about the day-to-day events of the race, where we are headed, and how we got to this point. Idaho, here we come!

Thoughts and Observations: Day Four (8/6)

We made it to Las Vegas! We know what they say about Las Vegas, New Mexico—“Really?  Where is it?”

It’s south of the border—the Colorado-New Mexico border, with real Mexican meals, not Taco Bell. Tired of hamburgers and Henrietta’s grilled ch**ken sandwiches, we searched out the locally owned Mexican restaurants—like Casa Lemus in Raton and Pino’s in Las Vegas.

Las Vegas is east of Santa Fe, somewhere north of I-40 and too far from Texas to toss an armadillo. We didn’t see any armadillos, but did we passed a deer waiting to cross the main street in Cimarron.

For our journey south from Raton to Las Vegas, we tried to avoid Interstate 25 when possible. After a two-mile stretch of the freeway outside of Raton (speed limit 70 mph—not good for solar cars traveling 35 or 40 mph), the race route took us across the rolling plains and into the Sangre de Cristo Mountains. The task of the Prez Prius today was to hopscotch ahead of the RA XI team and capture drone video. We found a well-suited rise on a two-lane highway and launched the drone. Yes, it does sound like a cloud of angry bees.

We debated what to call a group of angry bees—colony? Not rebellious enough. Hive? Too sweet sounding. Swarm? Already taken by the Iranian Revolutionary Guard navy. Our avoidance of a Wikipedia search was interrupted by the distant of “puph” or, in English, “poof,” only with a baritone sound. I thought it sounded like artillery, only it was happening much too fast and too many times and was very random. Who orders “fire for effect” in the vastness of New Mexico? The U.S. 1880 Cavalry was one suggestion.

Standing quietly on a rise at edge of the vastness of the Great Plains leads to all sorts of contemplation. The unexpected approach of the lead van, RA XI, and the chase van brought us back to our current task. The drone was in the air, and we filmed some fun video. Afterwards, hunched in the limited shadow of our Toyota Prius (it is a low car, so there wasn’t much shade), we critiqued the video.

We quickly packed the equipment and raced to catch up. The roads, two-lanes with limited shoulders, are straight with clear sightlines for miles. The benefit of emptiness is worry-free passing. In reverse order—race official observation car, Principia chase, RA XI, Principia lead, App chase, Runnin’ on Shine, App lead.

Miles ahead we spotted Appalachian State’s (“AppS”) version of the Pres Prius, a new model Ford passenger van sans president and drone. Their team’s photographers were standing on an unused railroad crossing. They had placed themselves to catch Runnin’ on Shine as it traversed the railroad crossing. We all watched as a local pickup truck went through that crossing (not much below 60 mph). It “caught air.” The vehicle’s forward momentum meant that all the pieces continued together for the foreseeable future.

If Runnin’ on Shine and RA XI weren’t careful, many pieces would “catch air.”  We all stood respectfully back as we photographed our respective teams. The drone footage was better than earlier. Given flight limitations (generally 400 feet), the Principia drone maxed at 100 meters. We didn’t have to guess, as the iPhone connected to the controls provides altitude readouts along with lots of navigation information, including maps of prohibited flying zones. One hundred meters is about 325 feet for those who calculate, or engineers who just know this stuff.

We were disappointed that we weren’t low enough to film the underside of either solar car. The footage from above, though, was great. If you freeze frame and zoom in, you’ll see everyone hunching tight, in expectation as Principia’s veteran lead van driver, the unflappable Steve Shedd, took the tracks. He took some air but didn’t seem to notice. You can’t tell from 325 feet above. With a right soundtrack, the video fit IMAX.

So, back into the Prez Prius to dash ahead. We passed Principia’s convoy, but Runnin’ on Shine was nowhere to be seen. It was faster than a revenue agent seizing an illegal still . . . that kind of shine.

We pulled into Cimarron for a quick stop. I was sitting on the curb when lead-solar car-chase whizzed by. I think Principia was filling the battery with “shine.” It took us more than 30 miles of country roads to catch up to RA XI. Perhaps it was because we dallied through Philmont, the famed Boy Scout ranch spread over 140,000 acres of wilderness. My older brothers attended Philmont in the late 1950s and returned home with imagination-filling stories of living the adventures of Kit Carson, Jim Bridger, or John Fremont. Now, I can write older brother Dennis and say that I, too, have been to Philmont. Or, through it.      

Most of our drive was along the edge of the Sangre de Cristo Mountains. Just the name evokes mystery and wonder, and it slowed our speed—not the name, but the mountains.

We also learned the source of the bangs, booms, or poofs—Whittington Center, the National Rifle Association’s version of a summer camp. We figured the deer felt safer with traffic in downtown Cimarron.

We caught up with RA XI as the convoy crossed into the plains. The next adventure would be a 15-mile detour to the monument at Fort Union, a U.S. cavalry outpost. We passed the convoy and dashed ahead (via the Interstate at speed limits of 75 mph). We found a rise on the blacktop to Fort Union with vistas in both directions. You can see forever—the Sangre de Cristos to the northwest; rolling hills to north and south; flatter plains to the east. Principia senior Mark Trinidad, the drone operator, practiced his techniques, including operating from a moving vehicle. He drove the drone; I drove the Prius.

We waved to friends in other convoys—AppS and Illini. When someone arrives at a checking station, particularly after an arduous stretch, the other teams rush over to share their adventures. There are always waves and smiles.

Below us, perhaps ten miles distant, was an isolated grove to trees where Fort Union stood. Now only a small fraction of its original 44,000 acres, the fort’s “location seemed ideal for conveying a clear presence of the power of the United States government.” As we read the explanatory board at the pull-off, we heard the rumble of a jet aircraft above, and not that far above. It wasn’t the sound of a plane flying at 35,000 heading to Dallas. It was a B-52.

How do I know? Two years living on a B-52 base as a kid! During the Cold War, the massive planes operated 24/7. It was never a quiet moment as they lifted off or returned from strategic patrols. The plane is big, with long wings, and four sets of engines. More importantly, it barely has a fuselage. The B-52 has a very narrow middle, like a corset had been left on too long. It doesn’t need much space for its load of bombs. Instead, it needs power to lift and transport the weapons around the world. The plane made a slow curve, coming from the Sangre de Cristo and banked gracefully to the northeast. Like the drone, you hear the bomber after you loose sight of it. It is “ideal for conveying a clear presence of the power of the United States government.”

Our jumble of thought was focused by the appearance of the RA XI and escorts in the distance. The drone was launched and positioned. Mark was honing his craft, with leading shots, following shots, pulling back, and moving in. We repeated the exercise as the team returned to pass us, heading back to the freeway.

We had lots of rich thought time: reflections on nature, beauty, history, power and persuasion, treatment of native peoples, new friendships. Perhaps the theme for this day was not the solar car directly but the unexpected opportunities that result from this opportunity. The night before, Missy had wandered around the compound of our lodgings. It was an old 1950s motor lodge, ala Howard Johnson’s. The rooms were simple and very large. The evening air was cool and clear, and guests were sitting on benches in front of their rooms.

Missy loves animals (don’t tell our cats, but her love extends to dogs). Several doors down the portico was a miniature English Bulldog. Missy wandered over to talk to the owners. She was bored with my conversation partner, a retired Navy captain of 35 years, who is our assigned official race observer. He takes his duties seriously and keeps his conversations with the team on a formal level. But, with me—we were swapping “war stories.” Jim is an aerospace engineer and a world traveler. He is one of those happy conversationalists with whom it is a pleasure to stand next to and watch the sunrise.

That’s what we did this morning. We stood in the morning chill and talked about taking the time to observe the unnoticed world around us. At 6 a.m., a pickup truck slowly rolled next to us . . . it was the Principia truck heading back up the Raton Pass to retrieve the trailer and solar car packed inside.

Shortly afterwards, Missy and I had breakfast. She introduced me to the couple who owned the English Bulldog. In their short conversation that night before, the wives had discovered that each was quarter-Cherokee. That is sufficient to be registered with the tribal council. The women exchanged business cards and promised to help each other continue to explore their roots and heritage.

As we left the staging stop in Las Vegas, we spotted two Principians sitting on the ground among several MIT students. Their attention was focused on the right front wheel of the MIT car. It is more than a car or a race.
