Finally, a “Jetdrive” Golf Club Head! Can You Imagine Air Leaving Your Club Head at a “Near Sonic Velocity”?
I am not sure what to say about this golf club patent application titled “Golf Club, Jetdrv Driver for Increased Distance and Accuracy;” other than to say that it is interesting (and it did not result in a patent being issued). The application published as US Pub. No. 20050032584 and contains the following figures:
The application describes the golf club as follows:
A golf club, driver, is designed with a nacelle surrounding the clubhead. This nacelle is designed to capture a stream tube of air that enters the club head, the internal air passage shape provides an increasing diffusion volume, reducing the air velocity, thereby increasing its pressure. The air is then expanded by discharging it, at near sonic velocity, through the nozzle at the rear of the club. The ram drag of the air entering the club is balanced by the jet thrust resulting from the change in momentum. The drag is then limited to skin friction on surface area exposed to air flow. This drag is far less than the blunt body drag of a conventional clubhead.
