Sandia labs researchers design self-guided .50-caliber bullet.
A team of Sandia labs researchers has come up with a novel design for a guided bullet.
Engineer Larry Shipers showed a rough sketch of the proposal to Popular Science, detailing how the new bullet should overcome some basic issues faced by weapons designers.
First of all, the bullet is actually not a bullet in the traditional sense. It is not spin-stabilised and it is much larger than an ordinary full-metal jacket bullet, as it has accommodate guidance electronics based on an 8-bit chip, an optical sensor and aerodynamic control surfaces.
The resulting design is more than twice the length of a regular .50 caliber bullet and as it is not supposed to spin, it would have to be fired out of a smoothbore barrel, which would have to be retrofitted to existing .50 cal weapons. The guidance system relies on a small laser sensor at the tip of the bullet and a cone-shaped control surface at the back.... Keep on reading...
