Bullet on Wheels, Designed in SolidWorks, Aims for 24-Hour Record; Human-Powered Vehicle, to Be Pedaled by Ironman Triathlete, Was Tested in COSMOSFloWorks' 'Virtual Wind Tunnel'.


CONCORD, Mass. -- A Canadian designer used SolidWorks(R) and COSMOS(R) software to develop and optimize a human-powered vehicle that will attempt the 24-hour distance record in July. Capable of more than 60 miles per hour, the machine is essentially a recumbent bicycle A recumbent bicycle is a bicycle which places the rider in a seated or supine position (rarely, in a prone position). Recumbents hold the world speed record for a bicycle and were banned from international racing in 1934.  - one where the rider lies on his back - encapsulated in an aerodynamic carbon fiber fairing.

The "Critical Power" resembles an eight-foot long bullet and will be the pilot's mobile home for at least 22 hours during the record attempt. Greg Kolodziejzyk, a top 10 age-group finisher in several Ironman triathlons, will assail as·sail

The retired computer imaging entrepreneur chose the Redwood Acres Motor Speedway in Eureka, Calif., as his venue after evaluating 19 other tracks in North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere.  for climate, surface, and layout.

"SolidWorks and COSMOS software helped us develop what we are convinced is a superior design from aerodynamic, mechanical, and ergonomic standpoints," said Designer Ben Eadie, owner of MountainWave Design Services in Calgary, Alberta, Canada. "But the proof will be laid down on the track."

Eadie optimized the vehicle's aerodynamics aerodynamics, study of gases in motion. As the principal application of aerodynamics is the design of aircraft, air is the gas with which the science is most concerned.  by creating a "virtual wind tunnel wind tunnel, apparatus for studying the interaction between a solid body and an airstream. A wind tunnel simulates the conditions of an aircraft in flight by causing a high-speed stream of air to flow past a model of the aircraft (or part of an aircraft) being tested.

After testing a series of established human-powered vehicle designs, he settled on an entirely new design that tapers to a thin vertical wedge in the stern.

The vehicle's shape resembles that of a fish. "We didn't start out thinking 'fish,' but when my designs follow nature, I always feel like I'm headed in the right direction," said Eadie. "Natural selection is probably the best design optimization See automatic design optimization.  process you can hope for." The virtual wind tunnel's findings correlated by more than 98 percent with calculations experienced on the track.

Eadie has used SolidWorks software since 1999 to develop the Critical Power as well as more traditional recumbent bicycles and special projects ranging from hydrogen fuel cells to diaper-changing tables. "With every release SolidWorks continues to prove why it is the most robust 3D CAD tool for designing better products, whether in carbon fiber, structural steel, plastics, or sheet metal," Eadie said.

The record attempt is sanctioned by the International Human Powered Vehicle Association The International Human Powered Vehicle Association is an association dedicated to promoting the design and development of human powered vehicles. It was founded in 1978 in the USA as an association of individual members with the publications Human Power and HPV News. .
