University of Toronto Human Powered Vehicle: Difference between revisions

The University of Toronto Human Powered Vehicle Design Team (HPVDT) is a design team focused around designing and building vehicles solely propelled by human power. The team's past and current projects include an [https://en.wikipedia.org/wiki/Ornithopter ornithopter], a helicopter, an airplane, a submarine, and numerous land vehicles.

==Human Powered Ornithopter (2008)==

<span></span><span>During the summer of 2008 a group of graduate students founded the club to design and build an</span>[https://en.wikipedia.org/wiki/Ornithopter ornithopter] (wing-flapping aircraft) that used human power alone. The project was headed by Todd Reichert (NΨ 0T4 + Film) and Cameron Robertson (NΨ 0T8). The ornithopter was successfully completed and made a record-setting flight as the first human powered ornithopter [[http://www.aerovelo.com/ornithopter-summary 1]

==Ace (2009 - 2010)==

The team built and competed with ACE. The team competed at the ASME Human Powered Vehicle Challenge and at Battle Mountain's Human Powered Speed Challenge. ACE's top speed was approximately 100 km/h. The team scored second in both men and women sprint events, as well as third place overall in the Speed Class at the ASME event, a great performance for a new team. Furthermore, the team scored the collegiate speed record at the Battle Mountain event, with a 103km/h run. This was the first year undergraduate students were a part of the team. ACE used an aluminum frame supported in a fairing constructed from Kevlar and carbon fibre. It's total length was approximately 9 ft.

==Vortex (2010 - 2011)==

In September of 2011 the team competed in the Battle Mountain WHPSC again, this time in hopes of setting a world speed record. After a week of racing the team marked a top speed of 116.9 km/h by Todd Reichert, still well short of the world record.

==Bluenose and Atlas (2011 - 2012)==

HPVDT significantly redesigned all aspects of the design  for the next iteration of speedbike. Led by co-captains Trefor Evans (NΨ 1T3) and Aidan Muller (MSE 1T3), the team proceeded to manufacture the Bluenose vehicle. This design boasted much-improved aerodynamics, highly-durable construction, revised steering geometry, and a new landing gear system. Bluenose competed at the 2012 ASME HPVC, where it won awards in the Design and Sprint events. The team finished 4th overall.[[File:Bluenose2012.JPG|500px|center|middle|thumb|Marissa and Todd at ASME HPV Challenge 2012]]

WHPSC 2012 was disappointing. A variety of handling and visibility problems prevented Bluenose from reaching its potential, and the team failed to improve upon Vortex's top speed.

<span>During the summer of 2012, the core membership of HPVDT was recruited to the newly-formed AeroVelo Inc. design team. The group relocated to Tottenham, ON, where they designed and manufactured the Atlas human-powered helicopter until September.</span><span></span>

Despite mediocre performance in the Design and Innovation categories, Celero placed well in both the Sprint and Endurance races. In fact, the Endurance race was won by an unusually-large margin; Celero finished the 2.5 hour event having covered nearly 20% more distance than the next-fastest vehicle. Overall, HPVDT finished 3rd in this competition. Shortly after this event, Calvin Moes (NΨ 1T3+PEY) was elected as the new Team Captain. Long may he rule!

==Valkyrie and ETA (2013 - 2014)==

HPVDT built a leaning tricycle for the ASME HPVC event. It performed well in the Innovation and Speed events, but was mediocre in Design and Endurance. The team finished 7th overall.

During the summer of 2014, members of HPVDT collaborated with AeroVelo Inc. to design and build the Eta speedbike. With a myriad of new design features and unparalleled aerodynamic quality, Eta was a favorite among the HPV community to set a new speed record. In order to better support the Eta project, HPVDT did not field any of its own vehicles at WHPSC 2014. Along with AeroVelo's top athlete Todd Reichert, HPVDT/AeroVelo riders Trefor Evans and Calvin Moes competed in the week of racing. Todd managed to set a personal best speed, but did not achieve the goal of a new world speed record. Following the competition, strategic differences between AeroVelo and HPVDT resulted in the two organizations ceasing large-scale collaboration. As part of this agreement, HPVDT retained the right to build a "clone" of the Eta speedbike.

==Viteza (2014 - 2015)==

Again working towards a more practical vehicle design, the team came up with a partially-faired lowracer - a recumbent bike with very little frontal area. The design included several novel features, including an ill-fated carbon leaf spring suspension system. The 2015 ASME competition was a mixed experience. The new Viteza design proved less versatile than expected, and the suspension system introduced unanticipated instabilities. Regardless, the team scored well in Innovation and won 1st place in the Design event.

<span style="font-size: 21px;">ETA Prime and Axios (2015-2016)</span><br />During the summer term, several members of HPVDT undertook to construct an updated version of the Eta speedbike, to be called Eta Prime. While not completed in time for WHPSC 2015, the new speedbike project made excellent progress. Among the modifications made were a lighter fairing, a stiffer frame, and an updated electronics package.

Concurrently with work on the new speedbike, HPVDT undertook to design and build a human-powered submarine with the goal of breaking existing records for both speed and endurance. The project began with a feasibility study followed by extensive research into hydrodynamics, SCUBA technology, and safety systems. By the end of 2015, all major design decisions had been made and work was progressing towards finalization of the hydrodynamic shape.

Through the summer, work on Eta prime was completed and the team raced it for the first time at WHPSC 2016. At the same event, former team founder Todd Reichert set a new absolute world record of 144.17 km/h (89.59 mi/h) in Eta.
