Need For Speed: 2014 Human Powered Vehicle Competitions

Calling the 2014 Human Powered Vehicle Competition “One of the best in terms of teamwork,” Missouri S & T HPV team member Jon Sanders details the Missouri S & T experience at both major competitions on the East and West coasts this year, where colleges and universities all over the nation competed to build the fastest Human Powered Vehicle.

Our article earlier this year outlined the major technological improvements Missouri S & T has implemented help them win – specifically, building a three-wheelend chassis instead of a bicycle chassis and using a new type of carbon fiber for the body. “In addition to being a great teamwork experience, after two previous years working with Coastal Enterprises donated Precision Board, this year’s tooling experience was by far the best we’ve ever had,” states Sanders.

On April 11, 2014, the Human Powered Vehicle Challenge East competition (held at the University of Central Florida) began. “We showed up at HPVC East knowing we would need to complete the vehicle on-site, which is obviously the worst-case scenario because it meant less time for testing than we were accustomed to,” recalls Sanders. “Nevertheless, we did complete our vehicle and some testing prior to competition. However, once  the competition started, we realized that the drivetrain was about twice as hard as it should have been to operate. This was due to imperfect alignment, meaning we had to push the tires instead of roll them.”

Alignment problems aside, Missouri S & T faced an even bigger dilemma at the end of the Endurance race when rider Jon Sanders collided with another HPV from the University of Central Florida, sending him into a wayside haystack. The full consequences of that crash became evident three laps later when the steering column, pushrod and balljoint snapped while team leader Nikia Chapman was competing. Unable to repair the vehicle, Missouri S & T team members pushed/jogged the vehicle to a finish.

Not long after, in San Jose, CA, HPVC West commenced on April 25th, with Missouri S & T in attendance this time with a much more extensively tested HPV. “We had time in between competitions to sort out our alignment issue, and also complete some additional testing,” explains Sanders. “We came into HPVC West much better prepared than at East, and it showed. Our car was performed beautifully until the end of the endurance event, when the steering column pulled out while I was driving. The only thing I could to was pound it into place with my fist every 100-200 feet to make sure it didn’t completely fail.”

“At HPVC West, we really came together as a group and were able to finish in third place overall,” states Jonathan. “Overall, I think the vehicle we brought this year was the best we’ve ever created.”

We’ve followed and reported on Jon and Missouri S & T for three years (since they started using Precision Board), compiling an impressive showcase of the progress the team has made over the years. Check it out and see how the team (and vehicle) has progressed!

 

2013 Human Powered Vehicle Challenge Update!

With the Human Powered Vehicle Challenge West competition coming up mid-April, last year’s champions at the Missouri University of Science and Technology are hard at work building this year’s HPV.

Fortunately for us, keeping in touch with Lead Fairing Engineer Jon Sanders means we have early access to pictures of the 2013 HPV coming together. You may remember Jon from last years blog: How Fast Can A Human Powered Vehicle Go?.

According to Jon, because of an improved SolidWorks design of the body, the 2013 “Colossus” HPV will be much more aerodynamic than last year’s “Kronos.” SolidWorks 3D CAD and Analysis software allowed the team to design the HPV and analyze airflow before the physical model was built.

This year, the mold was built using Precision Board Plus PBLT-10 and was CNC machined by .

After they received the machined Precision Board mold, the team members coated it with 5 coats of a Minwax fast-drying polyester sealer. A Duratec high gloss sealer, followed by an Orange Tooling Gelcoat application finalized the molds. After the molds were ready, the fairings were layed-up using a wet layup and vacuum bag method. Once curing was complete, two picture-perfect Carbon Fiber body halves were ready to be seamed together prior to mounting onto the frame.

Currently, there is much fine tuning being done before the April 12th unveiling of “Colossus” at the NASA Ames Research Center’s Moffett Field. Landing gear (which automatically deploys at the finish of each race), headlights, turn signals and more must be added before the HPV is complete. Check out the Missouri S & T’s Facebook page for more info and updates as the race date inches closer.
