Abstract

A projectile launcher includes a body having a rearward end, and a forward end. A pair of arms is pivotally coupled to the body and a bowstring extends between the ends of the pair of arms and is movable between a cocked position and a released position. Tubular torsion bars are coupled to the pair arms to store and release mechanical energy. A mechanical energy delivery system couples the tubular torsion bars to the pair arms. The mechanical energy delivery system transfers mechanical energy to the tubular torsion bars when the bowstring is moved from the released position to the cocked position, and transfers mechanical energy from the tubular torsion bars to the pair arms to move the bowstring from the cocked position to the released position.
