Where would I find out more about wind force?

[Kyle Stanley]

This curiosity began with my attempt to find a general simplified formula for wind force displaced perpendicular to a surface with relation to the velocity of wind and the area of the surface {analogous to the simple models in UP 1 for describing motion}.


This curiosity had its orgins with a kite project that I wish to modify to handle high winds and an ultra-light model for light breeze. I know such an approach must exist, I saw an equation several years ago when I was curious how to determine the maximum force from an F5 tornado.

So I have found some things involving drag coefficients and with this in mind... I am sure that this goes heavy into things like aerodynamics which is ostensibly way over my head and also into things pertainent to structural analysis. But I am looking for the simplified version so I can make sure to both provide adequete lift and adequate strength to the kite and line.

This is probably used to design sails for sailboats, wind turbines, et al.

So essentially my question is where am I introduced to this type of study and if possible how can one model this in a simple manner without the need for drag coef.?

Thanks for any suggestions.

I found something on this

E=Avt(rho)v^2

where E is the total kinetic energy
A the area perpendicular to the displacement of the velocity
t time
(rho) is the air density

this is what I was after, a formula to discuss the actual force {energy in this case}

With high winds you should try to have a big kite, as the force of the winds will mean that the area displaced by the wind is big enough. A small kite will have too much force on it and thereforebe swirling out of control!

With a small breeze you should try to use a small kite, as it is light to be taken up.

Thanks for your response.
