thanks! its run at 2.75 deg AoA and this was the first and only time i ran the car with the wing. More data is required, i am changing the set up on the car this year, big rubber, bigger brakes as well so the aero will play into all of it.
Well, this happened yesterday:
Weighs 26 lbs and I can stand on it in the middle. Since standing on your wing is apparently the good way to prove its strength. 79 inches wide (78 wing plus two 1/2 inch end plates). Total cost is about one small bottle of wood glue $2.50 and like 20 2 inch screws - $.50? Even if I bought a sheet of new plywood I'm only using roughly 1/3 of it. So this can be reproduced with new material for $20-$30.
Next up, testing!
Supports underneath and end plates are just screwed on for now, since I might want to move them around for testing. So far I think I'm around 4 hours of build time on this. Many more hours of planning and research though.
great vid Robbie! "Scientific Method" LMAO! i made my splitter from "reclaimed" aluminum honeycomb panels and bonded/spliced them together to get a panel big enough to be a splitter and then i used old pallets to make the internal structure of my wing that i skinned with aluminum from the trash. Wish i had the minerals to put a vid together when i made my aero kit...but making stuff for free is always cool - even better when it works!
thanks again!
Matt
Robbie,
I finally got around to watching your video of the wing forming/build. Well done on the presentation. It looks like you have a good base for further testing and development.
In reply to stafford1500 :
Thanks! Yeah I've been stuck the last few weeks with other work (mostly the explosion of all things plant that happens in spring with all this rain) but I am excited to get testing it.
I've also been steadily reading through library books on vehicles and aerodynamics, so maybe I'm learning.
Here's the testing thread, I will have lots of questions and will be looking for input for everyone:
so, are we going to get an 'after-action' report on how this/these did? Besides the one shot in another thread of how flat the wing is, compared to the roll of the body, I haven't seen much.
In reply to sleepyhead the buffalo :
Yes, I've been planning a write-up which I should finish today. I'm delinquent. Short version is they work well but we had other problems that prevented better data.
