Abstract (en)

Guidance, designed to control the trajectory of a high-velocity projectile such as a shell, bullet or missile with a conical nose, comprises generating a high-tension discharge producing a plasma on a first limited sector (28) in a given direction, and maintaining it while generating a low-tension discharge that feeds energy to the plasma in a second sector (27). The maintenance of the plasma in the second sector lasts at least one millisecond, though the two sectors are different and need not have a common area. The plasma generating tensions are applied between electrodes (A, B, C) on the projectile nose in groups (30, 31, 32).
