This is, as I read it, no different from the dimples on a golf ball. They are there to reduce skin drag. Also, sauce for the goose is sauce for the gander. It would seem the body would benefit as well as the wings. In any event, glad to hear they are looking at this.

I understand that when I take a 747 (coach) to Tokyo, I am getting 91 mpg. If we boost that 20%, I will be getting 110 mpg. Impressive.

Jerry, so you’re saying that 1) this has been tried or 2) this is impractical?

As an aerospace engineer with about a third of a century experience, I can safely say that any practical method for reducing aerodynamic drag has been utilized. Boundary layer control was around when I was in college using a slide rule.

It can be used also to lower the skin friction with blades of wind power units in that way it will reversed lead to more efficiency of the WPU.

Whatever way that we can assist let it be. I do hope that the world will take the message we are destroying our earth. It’s the only place that we can live. I like this good one.

I am aware of this technology which was published way back in 1985. I don’t exactly recollect it but it was published in Indian Monthly dedicated to Science. It is a great thing to happen now for aviation industry which will make air travel environment friendly and somewhat cheap.
