Spin-stabilized projectile with pulse receiver and method of use

A spin-stabilized projectile the trajectory of which can be improved to increase accuracy, said spin-stabilized projectile comprising:

• a nose end;
• a midportion having a periphery disposed about which are a plurality of spaced masses and a high explosive charge associated with each said spaced mass for high explosive detonation acceleration of its corresponding said spaced mass to provide an impulse to said projectile which is applied substantially normal to a longitudinal axis of said projectile;
• and
• a boattail assembly including a microdetonator corresponding to each said spaced mass for detonating the corresponding said high explosive charge of the last-mentioned said spaced mass by firing metal fragments, said boattail assembly further including a mechanical safe-and-arm mechanism to prevent accidental firing of said explosive charges, said safe-and-arm mechanism including a ring having apertures, said ring being movable from a first position wherein said apertures are not in position to permit said microdetonators to detonate their corresponding said explosive charges, to a second position wherein said apertures are in position to permit said metal fragments from the microdetonators to pass through said apertures to detonate their corresponding said explosive charges, said boattail assembly including means for permitting said ring to move from said first position to said second position only by said ring first moving rearwardly, second by rotating, and third by moving forwardly.
