Waterford 2018

The HPVDT attended the annual HPV rally at Waterford, Michigan last weekend. I was not able to attend, but Luke’s mother kindly provided some pictures. They follow below with minimal comment which might be updated as I receive more information from the team.  Enjoy!

I’m assuming that the team is putting three ‘liners through tech in this picture. Looks like it rained Friday evening.

For the first time that I recall, it looks like we have three streamliners on the track at once.

This is the most mysterious image of all that I was sent. It looks like Calvin is signalizing “2” through the vent just forward of the Vortex windshield.

The Michigan HPVA blog is here, and I will link to any forthcoming reportage on the rally.

Videos from ASME East

Here is our long form video of the endurance race.

In addition, ASME HPVC has posted some official videos in a 360°C format.

Check these out:

The slalom (turn it 180°):

The rumble strip:

Update:

The team was filmed by Daily Planet the day before we left for East, and the short feature was broadcast on April 17. It is about 11 minutes on this video.

ASME 2018 Day 3

Airbiter lives! The epoxy appears to have cured during the day Saturday, and the team stayed up until midnight reassembling the trike.

IMG_8235

So what went wrong? The consensus was that steering shimmy was induced by the flex in the steering linkage. The original layout had a vertical member linking the tie rod to the steering arm on the kingpin.

Now the tie rods are connected directly.

DSC05811The camber was off on the remounted wheel, but it was rideable.

Calvin practices before the start.

DSC05813Props to Rose Hulman who let many teams, including us, use their generator to power Dremels for emergency repairs.

DSC05815

UCF’s fairing conforms to their mascot, but that tail looks less than aero.

DSC05816

SD State is leading the competition, and you can see that they’ve added a grocery basket to their bike. They took it off during the race after doing the requisite number of drop offs and pickups.

DSC05817

Bikes lined up in order according to placement in the mens’ and women’s sprints. This puts SDSU and Akron at the front.

DSC05818

Since we didn’t run the sprints, we’re at the back.

DSC05821

Just to make things more fun, our left crank arm fell off and had to be reattached just before the start.

DSC05820

And we’re off, with the usual chaos of a LeMans start.

lemans

Calvin is delayed at the start because it takes a while to get belted in, etc , but is soon passing many bikes.

IMG_8236

DSC05826

Clarkson is determined to run their bike the entire time.

DSC05822

Sadly, MS&T’s very pretty bike had a wheel failure on the first turn and decided to soldier on with a shoulder harness.

DSC05824

Rider switch to Valina. We’re in the lead at this point.

DSC02261

DSC05827

Pedalling strong with a bag of groceries just behind her head.

DSC05828

Rose Hulman having their share of troubles.

DSC05840

Now it’s Evan’s turn.

DSC05832

Chain came unshipped during his heat. This started happening more and more as the race went on.

DSC05834

Evan comes into the pits after he’s had enough. His knees were bloodied from scraping the fairing. This was partially because we elected not to move the BB position in the transition to the taller riders.

DSC05841

DSC05842

Bill’s turn.

DSC05844The shoebox.

DSC05845

Good to see MS&T running again near the end.

DSC05846

Pitt had a nimble and fast unfaired recumbent, and strong riders. They won the enduro. Here they take the checkered flag.

DSC05848

Bill finishes strong.

DSC05849

Flat spots from braking, where we’ve gone through the tread to the blue rubber and fabric casing.

DSC05850

Team checking the online report of enduro results.  We came in fourth, dropping out of third just near the end due to some mechanicals.

DSC02264

The requisite group picture.

IMG_8243

Our team. Can’t get them to all smile at once.

DSC05852

DSC05853

Then time for lunch and the awards. Calvin is volunteering our table as part of a trivia contest while they delay to give the judges enough time to tabulate the results.

DSC02266

We get second in design

DSC02269

and second in innovation.

DSC02272

Then it’s time for the long drive home. Weather forecast is not so good, but we have trouble believing it as it was 30°C on Saturday.  Thanks much to hosts Penn State!

DSC02265

On the way home, we stopped at the original location of Duff’s for some Buffalo wings. Wings highly recommended. Duff’s beer not so much ; D’oh!

DSC02278

As we approached home, the weather got worse and worse. In Oakville, there was a sudden bang, and we had to pull off to check the bike. Part of the wooden stand had broken, and the straps were barely holding the bike onto the roof. We got to the next exit and strapped the bike back down.

DSC02280

All in all, it was a very eventful weekend. If we had managed to run the sprints, we would have placed well overall. As it was, even without the men’s and women’s sprint scores, we placed eighth overall. As always, I am extremely proud of how the team performed under pressure.

Full results are available here.

The future of the team is in flux, as Calvin is stepping down as captain, and many of the senior people like Arbiter project lead Bruce are graduating. The team is also seriously considering not coming to ASME anymore. The competition is structured so that bikes such as the ones we tend to build are not favoured. This is not in anyway to diminish the achievements of the teams that finished at the top of the field. Most of them are better organized than us, and in particular South Dakota State has executed brilliantly, winning East (and they were second last year), and West this year as well.

The only thing that is fairly certain is that we will show up to Battle Mountain one more time.

ASME 2018 Day 2

The day started bright and early with the drivers’ meeting at 7:30.

DSC02254

There’s always more to do on the bike.

DSC02255

Bruce and Valina.

DSC05797

Bikes lined up for women’s sprints qualifying. The top 16 teams go forward. They line up in order of bike number. We’re number 12.

DSC05803

At the front is Rose Hulman. It doesn’t look like their female rider has much forward vision.

DSC05806

Lined up with Akron, whom we hear did very well today.

DSC05807

DSC05808

We’re lined up with DTU with their volunteer female rider.

DSC05809

Velina all enclosed now.

DSC05810

Her run started strong, but then we saw some speed wobbles, and then a sudden swerve as the left front wheel buckled.

Viewing the aftermath.

DSC02258

The team took the rest of the day trying to repair the damage as best as possible. It remains to be seen whether we can run in the enduro tomorrow. The consensus was that there was too much flex of various components in the steering which allowed the wheels to toe out dangerously under speed, and the resulting dynamic loads were much higher than anticipated.

Wish us luck.

ASME 2018 Day 1

Friday the thirteenth is the day that we arrived at Penn State. Tasks for today: finish prepping  the bike, giving a design presentation, and then passing the safety check.

DSC02229

Susanna is our maven of all things electrical.

DSC02226

Recumbent enthusiast Gary dropped by on his homebuilt LWB USS machine. We met him two years ago when HPVC East was at Athens OH. He reminded us that we didn’t get our bike rolling that time, and was impressed that we had a working vehicle.

DSC02241

However, as is traditional for our team, we are finishing the painting just before tech inspection.

DSC02234

Masking the other side.

DSC02237

Now we are more or less ready to join the line up for safety inspection.

DSC02239

Safety is the first time that we get to look at some of the other entries. Check out the pool noodle seating on this one.

DSC02246

Clarkson continues to believe in the superiority of their arm powered design.

DSC02230

This number from Delhi Technical University had its look somewhat spoiled by the grocery basket grafted onto the rear end.

DSC02232

Lamar University’s vehicle was excused from the roll over test because doing so would have destroyed their fairing.

DSC02233

One surprise was that last year’s winner, Rose Hulman, showed up with a vehicle that did not look fully finished. It is their first ever tadpole.

DSC02238

We literally had the paint finish drying while we were in line waiting to be inspected. Here the masking tape is being peeled off.

DSC02244

Calvin starting the dynamic safety test. DSC02245

Our least favourite part of the safety test, inverting the bike to show that our tallest rider doesn’t have his head touch the ground with the vehicle is fully inverted.

DSC02249

Evan having survived being upside down. Also, not too bad for a last minute paint job.

DSC02253

We’ll be up bright and early tomorrow for the women’s and men’s sprints. Forecast is for sunny and hot weather, just like today. Fingers crossed.

Update: we scored second in both design and innovation, putting us second overall heading into the dynamic events.

ASME 2018: Day 0

We’re on the road to ASME HPVC East in State College PA.

Late this afternoon, the team was doing some last minute structural tests.

DSC02215

Then it’s time to load up the van and put the vehicle on the roof.

DSC02218

The “before” picture.

DSC02223

As the van doors close, Isaac, Luke and Calvin Jr. bid us a fond farewell and good luck.

DSC02225

Looking forward to passing safety and tech inspection on Friday.

ASME HPVC: one week to go

Tonight marks one week before we leave for ASME East. We were happy to get our vehicle complete to the point where we can start testing vehicle dynamics.

We have a week left to tweak the trike and to make it look pretty. Looking forward to the competition!
