This post is for people asking how/what I'm doing with the windscreens I obtained recently for making a possible quieter design.
I asked for a couple of OEM windscreens in the WTB section, and a few weeks or more ago I got 2 of them.
One, (not sure if the persons want me to name them, so I won't), was exactly the type of screen I wanted; scratched, stickys, and what not all over it. PERFECT!
I thought of making a type of wind tunnel out of a fan and streamers, but I don't see that working too well. SO....
I'm wanting and am trying to make a paper pattern, that I can use to make facsimile cardboard windscreens, (only a facsimile, as it will lack many of the compound curve qualities and only be 2D), so I can try different ideas until I get one I like.
I attempted using it to make a pattern. I then found out, as with many things that look easy enough, it wasn't. The screen has many compound curves to it making a trace difficult. With temps in the 90's F, and raining everyday, I taped 65lb cardstock the screen and set it outside. The humidity helped the cardstock form better to the curves, then I traced it out and cut it off the plastic windscreen.
That's as far as I've gotten for now. I need more cardboard, and with it raining everyday for a month now, and still in the 90'sF, I'm waiting on Mother Nature to help out a bit. I think for now, I may do a basic CAD drawing, or at least a full size basic drawing in Paint shop Pro that I can print out when I'd like.
My first idea though, is to cut shark-tooth like V's in the top to break up the airflow into different directions. I'll try and add pics later.
