You would first need to get the properties of the fluid medium that which you are working with.
I would nto use a flat plate because a wire and a flat plate are going to give you two entirely different numbers, just of the top of my head.

I am assuming that you're referring to a triple gimbal system?
I may be able to provide some assistance for you, do you have email? can you send me an address for a web page that you might have with a pic or design layout etc? I'd need to look at some specifics before I was able to offer any...
Here's what I recommend, go to www.zenithair.com and get a STOL 701 and be done with it.
WIll changing the spand, chord, airfoils etc, be handled in the existing airframe or are you going to beef those up to handle the new loads? Joseph Moylan

Yep, first identify how the moments are going to happen or happening, if any, then determine the right equation from there!
lets face it, there's a Polar Moment for just about anything right? it's in the books and the items are not moving in them, so first determine or even "hey, is this...
Ok, here is some information that may help you.
For approximations, your probably going to get sick and tired of hearing those terms....Approximate values....I can only say get used to it. Engineering is not absolute with anything other than close estimation to anything closer than 2% to 5%...
There is another Tip loss factor, one based off of geometery.
B = 1 - Ctip <-- Ctip is the Tip chord (width) in feet.
----
2R <-- R is the rotor Radius
a common number in the industry is to have a tip loss factor of .95 to .97 dont expect 1.00 or unity, you wont get it...
Also, one thing that should have mention made to is this:
In terms of your physics project, just what are the parameters that you're suppose to identify?
Guys, try a 4412 or 4415 inverted airfoil. You could also try a inverted 23012 for a race car im assuming that you may wish to have a lot of "negative lift" to push the rear of the car down for better traction and handling correct?
I'm not a race car person in the least bit, and my...
Have a question for all, I need to find out what methods, information which may be available for, Airframe construction costs, machining costs, etc etc etc. If anyone has any knowledge of this, or where to find some information pertaining to such. Such as companies etc etc, i'd be a very happy...
SCALE EFFECT:
The three wings are obviously different, and thus will give different properties, delta wings offer good lift and eccelerated speeds, say Mach and higher, and swept wings, give the same loading with reduced tip loading stresses as well as reduced drag, thus greater efficiency of...
Thrust / Disc area is your disc loading.
if you have say 25,000 lbs of static thrust, and disc area is 2261.978 sq/ft then your disc loading is:
11.052 lbs/Ft^2
Your referring to the "Figure of Merit" ratio which is the measure of a rotors efficiency, as well as "Hover Power Req'd", and Power correction factors, etc etc etc.
The best way to answer this question is to email me at moygr1@home.com (that's a one not an L) and state...
