Rainy here so with time on my hands I get wordier and my posts longer.
Amazon is selling me these 3 in the photo: Digital Manometer, Pitot & tubing. VMan455 is generously sending me pucks.
Tomorrow after the rain I shouid be able to do my first tuft test. Chaotic yarn will explain my lack of drag reduction. Attached flow would be perplexing.
In the mean time I have 2 theories: 1. Cuff needs smoothing, and 2. Corners leak to much air weakening sequestration. I will work on both today or tomorrow between rain showers. Then tuft test. Pressure test will have to wait a week.
I really am kind f surprised to see no improvement with 3 huge 11 degree slopes.
Thoughts anyone?
