Drag Coefficient help
Posted: Mon Sep 12, 2016 9:49 pm
So, as I return to my ventures in bottle rocketry, I must ask the question:
What are the drag coefficients of certain configurations of bottle rockets?
More specifically, what is the (estimated) drag coefficient of a bottle rocket built for backslider recovery? I need to know it so that I may be able to find the optimum amount of water for my rocket.
My bottle rocket is an extended backslider that has a 4-ft fluorescent light cover with the base of a (tiny) Easter Egg on top I cannot give much more info here, as it is a mostly secret project...
Oh, and it is a 2-liter rocket, that uses the top end of a bottle as the adapter to the FLC-tube. You would know, a basic backslider design.
And of course, I would love it if there was a table/spreadsheet/pdf/word-doc, that had a table of values and images to correspond to those values.
Thank You!
