Infusion wins first place
The infusion was intended to be a vehicle innovative in every way. In addition to utilizing hydrogen fuel cell technology, the body of Infusion is unique in that it is modeled after the shape of a teardrop to minimize air resistance. Students utilized
AutoCAD and Rhino to design the vehicle completely.
Infusion uses a complex system of regulators and valves to store ultra-pure hydrogen to run the Ballard Nexa fuel cell. The fuel cell outputs 1200 watts of power, equivalent to that of a hairdryer.
Infusion is a three-wheeled vehicle with a carbon-steel chassis and bulkheads made out of aluminum and Nomex honeycomb composite material. The front suspension of the vehicle is composed of dual A-arms wrapped around torsion bars while the rear suspension is composed of a swing-arm and single bicycle damper. The rear wheel of the vehicle is driven by a belt from the 12-horsepower motor.
Infusion’s body was constructed at Cerritos College by students of LAAE’s composites team. The body was manufactured using an
environmentally friendly, state of the art; a technique called infusion impregnation to produce an extremely light and strong body. The body took four attempts and two years to complete a body that met the weight and structural requirements.
The LAAE at Los Altos High School is a joint program with the Hacienda La Puente Unified School District and La Puente Valley Regional Occupational Program. Founded in 1989, the LAAE is one of the remaining career and technical education programs in California. LAAE has many notable achievements in building electric and solar vehicles. The mission of the Los Altos Academy of Engineering is to establish opportunities in mathematics, science, computer science, and engineering for students who demonstrate an early interest in these career fields
Tomorrow’s engineer’s passion starts at the Los Altos Academy of Engineering.
