Reply to "Air Data"

I've still got work to do but I wanted to see what the data would look like. The weather broke a a little today so I threw it in the truck. To be fair, I still need to do a few things (besides the new circuit). I need to mount it on the front of the truck so I can calibrate all sensors so I can make the sensor range the same.

The truck is going to be nothing like the Pantera. The truck has a rain deflector at the window and elephant ear mirrors so I expected a bit of a turbulent airflow.



Notice the high tech plastic bucket.





Here is the data with some corrections:






That's a little confusing so I reversed it and zeroed it in the spreadsheet before re-charting it. This makes a little more sense:



The actual value is irrelevant. What the air is doing and how it compares is relevant. Sensor 1 is 1" from the window. Each is spaced 1". Sensor 5 is 5" from window. Speed is 0-75mph.

What I can surmise is the air is quite turbulent along the side of the truck. I would not call this a laminar flow.

To make a little more sense of the jumbled data I looked at #1 and #5:



Here's the rest for comparison:

Sensor #4 and #5 almost mimic each other and #5 almost seems slightly less erratic....slightly:
