no axial force bias in these quick and dirty garage wind tunnel experiments

E-mail Print PDF

I did a bunch of quick-and-dirty (I'm a caveman focused on guiding folks in the right direction in a timely manner, remember!?!)  garage based wind tunnel experiments in 2009/2010 to gain some insight into the magnitudes of the aerodynamic brake effect.

These garage tests I conducted were primarily driven by my healthy skepticism of the results presented in a marketing report made at the time.  The co-authors of this marketing collateral made field test based claims regarding aerodynamic brakes.  I've shared my own data and experiences regarding the challenges of field testing over the years here on BTR.

 

[Aside: Speaking of the Chung method based field test results in the above linked marketing paper..a baseline CxA of 0.215 on a P2k years ago is pretty impressive!]

Anyway, looking over old data and test configurations, I compiled this image of the setups I investigated:

the data are interesting, especially for the middle row of images...
