Center of pressure help?

Recommended Posts

I read an article on the effect of the center of pressure and CG on skydivers and how. Something about theres a big diffrence when it comes to freeflying vs bellyflying because when freeflying the CP is farther away and at more of an angle etc... etc......

If someone has a link or cares to enlighten me I would greatly appreciate it

Well, it's difficult to know what exactly the article is referring to as being different betweek RW and vRW, but in aerodynamic terms the center of pressure is a concept similar to the center of gravity.

It can be thought of as the point along the wing over which the lift is balanced.

You can sort of think of it as where you'd hook a sting to suspend a model airplane.

I know that but because of your body shape in lets say a sit your cp will be in front of your face and your cg is in your lower torso vs on your belly where cp and cg are in almost the same spot. This has some minor effect that I can't remember. I thought I downloaded the article it but I didn't. grrrrrr

Sounds like the article you are talking about....:)
Probably more easy if you think of this as the 'centre of drag', which I think is the way that Pat Works describes it, I may be wrong as I haven't had my morning coffee yet.;)
