Amateur aerodynamics

Orthogon rising

I pretty much decided to abandon the project and when I went into the garage the next morning I changed my mind again so I'm moving forward. Damn the torpedoes!

One more

yay!
Hope you can find some

yay!

Hope you can find some good prices for the composite materials. If you decide that the twin towers are causing too much crosswind lift you could perhaps fair over the valley with your ever-useful storm window plastic film so that you can still see out front.

Mike (carolina) over on BentRider is building his own velomobile from scratch using molds intended for a BD5 kit aircraft to derive his velo body from. He recommends these guys and suggests people talk to Jake about their needs.

Sounds like they can offer better pricing than some and are willing to help fulfill odd size/amount requirements at cheaper cost.

PS - It gets hot inside these kinds of things from both outdoor heat and the heat generated from your body. Consider an air intake at the center tip of the nose. This is a stagnation point in terms of air boundary layer (drag) issues so putting an air intake (ventilation) here should not adversely affect your aerodynamics.

the shape is a bit

the shape is a bit reminiscent of flintstone's brontosaurus earthmover...

Fred Flintstone is perfect

How do you think you go in reverse in a velomobile?

[LarryOz]

turn it around?

I give up...

 

[Eric Winn]

Velomobile reverse is via the Fred Flintstone method

A carbon mango? Spendy!

A carbon mango? Spendy! What's the weight?

What the cat saw

Enough spackle already, time to coat the plug.

 

[Jim Gerwing]

To be fair, another perspective

 

[Jim Gerwing]

Sealing the plug

Over the next few days I'll paint the plug with a primer/sealer. Not much to show except it's white and shows off the imperfections. This is a low budget operation so I'm considering what materials to make the fairing with. It's not going to be carbon fibre.

Hi Jim,
I'm very much

Hi Jim,

I'm very much enjoying your progress and this thread. Keep it coming!

We all live in a yellow, err, white submarine, a white submarine, a white submarine...

Very cool!
