Supersonic Golf Ball

Well, good news everybody! I have managed to get a team of people together that are willing to pool resources together for construction of a high energy supersonic Golf Ball cannon, complete with remote electrical control and operation. The Cannon will feature complete autonomous reloading of the barrel. I will have to create large quantites of gun cotton, otherwise known as nitrocellulose. Nitrocellulose has been used as a propellant and explosive for many years. The gun will also feature a passive recoil system consisting of the barrel mounted to a triangle plate with a system of springs to dampen the enormous recoil encountered by the barrel upon firing. Once fired, the compression springs will return the barrel to normal firing position, and will prevent dangerous whiplash. On the end of the barrel, a flash supressor will help reduce the enormous fireball that will be created when fired.




A .50 caliber bullet fired from a Browning M2 machine gun travels from the gun at 887.1 m/s, and the round weighing approximately 45g (or .045kg) will have an approximate Kinetic energy of 17706.294J. The golfball, weighing close to a .50 cal bullet at .0459 fired at mach 2 (about 700m/s) will have a kinetic energy of 11,245.5J of kinetic Energy. That means that this golf ball will have the power close to a .50 cal bullet.

Table of comparisons to Golfball

Supersonic Golfball (Mach 2) = 11,245.5J
.50 Caliber Bullet = 17,706.294J
.44 Caliber Bullet (Magnum) = 1904.4J
9mm bullet (Typical Handgun) = 640J

As you can see, this golfball will have a LETHAL amount of force behind it.


(These are rough calculations, taking the velocity of the bullet and mass into consideration only)

Will this be a rifle type device? Shoulder mounted? Mortar style?

Definately Mortar. A device with this much power will have an incredible amount of recoil. I am looking into building it into a howitzer look alike.




I am currently researching the best way to produce large amounts of nitrocellulose, Hydrogen Gas, or some other propellant.

This'll be a cool project for the Something Else category.

Remote electrical control and operation will be handy in preventing your early demise should your cannon explode. ; j
