This is the beginning of my quest (pun intended) of gathering information for building a velomobile body for my delta trike. I’m not an engineer but I have always been good at interpreting information of others and applying this knowledge to my needs. This post is just that, my gathering of information and storing this information for later assessment. At this stage of my study, I tend to put down information as it comes to me and rewrite at a later date for more clarity.
My first bubble to burst was that my delta trike with a longer more narrow front could be made more aerodynamic than a tadpole trike. It seems that opening a hole in the air is not as difficult as closing that hole behind you. What always looks aerodynamic may not be so. The Quest seems to be good at closing the hole with it’s long tapered tail section.
My first attempt at designing a velomobile will be made of Coroplast for ease of construction, weight and cost. In my minds eye, it may be more angular than most of the designs. It will be roomier than most as I have hopes of touring in this vehicle and carrying my gear aboard rather than pulling a trailer.
Here is a list of sites for which I’ve been making some of my new assumptions.
Human Powered Vehicle SPEEDS sorted from fastest to slowest This is one of my favorites, give me a picture and the results.
How to RECANVAS an old CANOE? Try a new simpler method I would also like to hear from anyone that has tried this on a velomobile. I’ve seen it mentioned on several sites but as far as I know hasn’t been tried.
EDIT: Well it has been tried and quite successfully so. Rick Gritter has a stream-liner that looks great and was built with the frame and Dacron skin. More on the next post.
The Dacron/Xynole/Epoxy Matrix Duckworks Magazine. Lots of information. The more I read of this, the more promising it looks
Google “heat-shrunk dacron fabric” and plans from canoes to ultra light airplanes will surface.
I’ll paraphrase a statement I read on BentRider Online I think. Any faring is better than no faring at all. A good faring is not that much better than any fairing and the best faring is not that much better than a good fairing. I think there is some truth to this statement but I think the spread is a little wider than that. I’ll find the thread later.
If you have links that would be pertinent to this study, you can leave them in a comment. Thanks
I at least have my links in place and can go back and study again.
I did some additional research and went to several sign company sites/forums and to http://www.coroplast.com checking on the UV resistance and life expectancy of Coroplast. This statement was copied directly from the Coroplast Company site. “Coroplast Archival is not recommended for any application in which it is exposed to high amounts of UV radiation, including all uses outdoors.” No outdoor life expectancy was given on the Coroplast site. Many differences of opinion were given on the sign company forums ranging from 1 year to many years (?). Most commenting on the matter was of the opinion that it was only 1 or 2 years.
I may look into other options like used aluminum printing plates or veneer used on doors.
