Future plans

Ok, so 2013 wasn't the most productive year for the team. With my job at SSL keeping me busy with crazy hours I haven't had any time to work on the bike for months. That has now changed. There have been some recent developments that will finally get the team moving forward again.

1) I recently bought a new HP all-in-one computer with a dual monitor set up. I'm currently looking into several free mechanical CAD programs that we can use. Some of these are open source. Powershape-e and DesignSpark Mechanical seem the most promising. But there are many other impressive free mechanical CAD software I will be looking into.


 
2) I also acquired quite a bit of 80/20 tubing from my company for free. We can use the tubing for a frame jig and/or building a recumbent version of the Serotta frame fitting system.

3) We have a workspace that may work for us to do our work. The one drawback is that there is no electrical power. We'll have to work on this drawback.

But I believe 2014 will be our year and we will build on first speed bike. We have much work ahead of us but I look forward to the challenge. Battle Mountain 2014 here we come!

Muffler Tubing!

So here is the muffler tubing we will use to build our first test frame. It's 2" OD x .067" wall thickness.

We have a sponsor and a workshop!

I'd like to announce our very first official sponsor, Thermal Conductive Bonding, Inc (TCB). TCB is manufacturing company that specializes in sputtering and elastomer bonding and molding.



Due to their generosity the San Jose HPV Club now has a place to do work. This will be our "workshop"!


Our first step is to clean up the area, set up a work bench tooling and storage racks, and move the foam molds in. Now, it's time to get to work!

We are back!

So after a rather long "summer vacation" the team is back at work. :-) We have finally moved the molds to a wherehouse in Santa Clara which is a good long term spot for them.  So our short term goals are the following:

1) Build a training bike for Meghan. We plan to build a "clone" of the Bacchetta Strada. We took vavious measurements and photos of the Bacchetta that we rented back in May. Meghan liked the ride and feel of this recumbent. It seems a straightforward frame to duplicate. But when building anything there will be problems that will arise.



2) Build a test faring to give the team some practical hands-on experience performing a vacuum bag wet layup.

3) Build a test frame based on this sketch.


This is just a preliminary first design. I'm sure it will change quite a bit as we do subsequent frame design iterations.

More to follow!...

Hellyer Velodrome 5/19/2012


We had a blast at Hellyer Velodrome. Meghan got some good experience riding the Bacchetta Strada and I got to be silly.

Dialing in the Riding Position

We had a good ream meeting tonight and we worked on Meghan's riding position. I think this looks good so far.

"And so it begins"-- Kosh Naranek

So the real nitty gritty design work begins. Were now working on getting the frame configuration nailed down. Using the measurements of Meghan's limbs we created "stick girl"! And we added a 20" front wheel and a 650C real wheel. It looks like we can possibly move Meghan forward and lower he a bit as well. We'll try out many rider configurations for sure.

Initial Rider Measurements

Now it was time to take measurements of Meghan to to get an initial view as to how she would fit in the fairing. Full  scale side and top profiles were printed out and taped to large flat pieces of cardboard.  There is plenty of room for Meghan so hat is great news. We also took body measurements as well. The next step is to create a 3D mannequin CAD model of Megan to see how laid out she can in the fairing.

So It Begins

Using a 48" x 96" piece of cardboard, Jose and I put together these two full scale profile outlines so we can start fitting our rider Meghan and designing the prototype recumbent bike frames. This is a classic example of high tech, cutting edge engineering CAD (Cardboard Aided Design). Hahahahahahaha! (I got that joke from a poster over at www.recumbents,com). These profiles are of the two sets of fairing molds we acquired from the Cal Poly, SLO HPV team (the Atlas and Artemis HPV's). We intend to modify the profiles and the molds to get shorter fairings by placing the Meghan in a more laid out recumbent position. We are even considering getting rid of the canopies all together if possible. We haven't decided which one to to focus on but the Artemis is the front runner since Meghan is our lead rider and she likely fits better in the Artemis fairing. We are also considering recessing the wheels deeper into the fairing body to lover the overall fairing height even further. This will necessitate that the rider straddle the front wheel (something that the riders of the Artemis riders didn't do because of their frame design). This seems to be a common design attribute with many of the fastest bike that race at Battle Mountain. But that has yet to be conclusively determined. We plan to measure Meghan's key body dimensions to get a better idea how she may best fit in the Artemis fairing.

Materials Update

So we now have the lumber for the mold boxes and a 10' piece of muffler tubing to use for our first prototype frames. So we can really get down to business and start designing the two prototype frames.

The Cheetah HPV (1992)

One of my favorite HPV's ever. The Cheetah held the World Speed Record (68.73 mph) for about 9 years I think.



There is a short clip in the video showing the Cheetah team performing an aerodynamic tuft test. It shoes  the airflow over the Cheetah faring. The airflow seems smooth over the sides but then goes turbulent at the tail section.

Visiting Cal Poly, SLO

On Saturday, January 7, 2012 we visited Cal Poly "aero hanger" to pick up the molds for the Atlas HPV. It's always fun to go back to where I spent so much time as a student! :-) The current Cal Poly students working on the HPV are an impressive bunch. They were hard at work sanding their current molds. I wish them the best at this year's ASME HPV competition.

Visiting George and Carole

On December 10, 2011 our team visited Carole and George Leone. We had a blast! He showed us Primal 2 and we got to ride the newest Cal Poly HPV prototype.  Meghan rode a recumbent bike for the first time ever and she took to it immediately. I look forward to see what she can do once she gets some training in a recumbent. :-) We also picked George's brain about HPV's for several hours. All in all it was a very productive trip. We'll be returning to visit them soon! :-)

 Riding like a pro!

I hope Meghan is smiling like that when she's going 70+ mph!
