Abstract: An air cannon apparatus and system for test launching golf balls. The apparatus includes a barrel sized to slidably receive a golf ball, an air pressure tank coupled to the barrel by an air control valve, a golf ball air clamp assembly for holding a golf ball for rotation about a spin axis within and transverse to the barrel, and a servomotor coupled to the air clamp assembly for controlledly spinning the golf ball prior to launching. The air control valve releases a charge of pressurized air from the air pressure tank into the barrel against the spinning golf ball simultaneous with releasing the clamp whereupon the golf ball is launched from the barrel. The system also includes a frame assembly for lockable positioning of the apparatus at a selected inclination angle and a system controller. The apparatus is selectively rotatable to vary the angular orientation of the spin axis.
