Chapter on reducing aero drag has gone to F1 aerodynamicist for feedback. He said of the Prius trailer: "Nice!" That's a pretty good compliment - this guy does not give such statements often.

Mr. Julian Edgar!

OMG! You are here! I have been following your work on Autospeed.com for years! You are inspiration sir! You and your team's work is nothing short of brilliant. I am totally speechless right now.

Sorry, as a contribution to this thread I would like to provide an overview of an air deflector I had made several years ago. I had a blog about it you can see it here

https://neoinfoxchange.wordpress.com.../aerodynamics/

Initially it was an excercise of a modulated spoiler on a hatchback that I had linked to an arduino. Then during the tests I found that I could reduce fuel consumption with a deflector rather than a spoiler. My hypothesis is that air over the edge of the roof can be directed towards the rear and reduce the size of the trailing wake.

The blog post includes a screen grab of a video I had put up at Flow Illustrator; an online 2D flow visualization software.

Before Deflector


After Deflector


The idea was that this could be made commercially available and would be non intrusive to existing body design. Allowing easier adoption to the masses rather than a full blown teardop mod.

Thanks for the praise. Your modifications look interesting and I am sure you will find plenty of useful info in the book.

The book contents are only now ready to go to the publisher, but they've already done the cover.

It's always fun when you're getting experts to read drafts and those experts don't always agree with one another! That slows things down a bit - but it also means that lots of things are very carefully considered.

And I've just realised it's available for pre-order here.

new book launch

Hope they fly off the shelves!!!!!!!!!!!!!!!!!!!
I'll do my part to help.
The 'democracy' where I live needs as many informed citizens as it can get.
I think your book will help, as we stand at the crossroads of an unknown future.
Thanks again to you and all who helped.

Another page has a photo from Earl.

One full page on Jim.

Another page on Darin.

A full page on Philip.
