Hi all,

My senior design group is going to be making a partial (but still large) fairing to mainly serve for weather protection on a utility human powered vehicle we will be taking to the 2010 American Society of Mechanical Engineers Human Powered Vehicle Challenge. We would like for it to be at least partially see-through and as lightweight as possible. In addition, the fairing will have to incorporate some means of rain deflection so the rider's vision is not obscured. Also we have no experience with creating molds or fairings and limited space, money, and school resources. Basically, does anyone have any material/coating/construction suggestions, advice, or helpful links for a mold or fairing? Currently, we are looking into possible combinations of Dachron, PETG, and chloroplast.


Also, my team still is in great need of sponsorship (small and large) in the means of monetary and parts (new of used) donations, so if you can help or know anyone interested, it would be greatly appreciated. The donations go through our university and are tax-deductible. You can find out more at www.teamrecumbent.com/sponsorship

Thank you for your time!

Lesley,
Are you designing a 2 or 3 wheeled vehicle?

I was thinking that a head canopy over that extended forward over the riders head by about 10" would be effective at blocking the rain and sun. No windshield so that the rider gets effective face cooling and won't require a wiper. If it's utility and speed is not an issue. I'd make it boxy to speed up the process. What is the utility this vehicle will be providing?

Sean,

It is a 3 wheeled vehicle with two wheels in the front (recumbent tadpole trike).

Utility as we see it in Houston, TX requires rain and sun protection for the rider and cargo, rollover protection, versatile cargo storage options, a minimal amount of specialty parts, reverse transmission system, minimal vehicle weight, climbing ability with the extra cargo weight, a basic lighting system, a horn, comfort during prolonged use, the capability to cruise at twenty miles per hour, and stability at regular operating speeds.

We had thought about creating air intake vents or something along those lines through the fairing, but having it open like you suggested is a lot cooler, less complicated, and a good way to incorporate the sun protection and not have to worry about the obscured vision.

The vehicle is utility, so speed is not the main goal, but we would still like it to be fairly aerodynamic. The competition requires us to have a fairing that at least covers 1/3 of the frontal area and is large enough to display the vehicle number (it also has to be large enough to fit all of our sponsors' logos). That is why we thought about a fairing that extends from the front fairing to the rollbar to fully protect the rider from the rain.

Thank you for your suggestion!

I just got a great deal on a Speedpoint bar and fairing combo and will need to get the fairing painted as it comes in matt black. My bike is an 03 Anniversary Anodised and I would welcome opinions on best choice of colour. My initial thought was to match it up with the frame but I need to find out the exact colour HD use.Preferably I would like to match it to the airbox etc but doubt that a paint will get the same effect. Any ideas?:thumb: Lime Green Kaz would be honored
