I had invented a new aerodynamic concept to reduce drag. The CFD analysis shows Horizontal velocity vectors at Trailing edge. I think this implies zero pressure drag, since all the kinetic energy given to initiate vertical velocity is given back to body at trailing edge. If not so what are the reasons for that. Please comment. I am inviting your esteemed opinion in this regard. For details on my concept follow the link http://sites.google.com/site/highlyaerodynamicdesign/

The snake oil makes the flow slip at the trailing edge.

We went through this same exercise a while ago.

That was funny! Is there any technical reasons? Please be serious. I took lot of effort to make this concept
