Title
(EN) SYSTEM FOR CONTROLLING A PROJECTILE WITH MANEUVER ENVELOPES
(FR) PROCÉDÉ DE COMMANDE D'UN PROJECTILE AU MOYEN D'ENVELOPPES DE MANŒUVRE
Abstract
(EN)
A guided projectile including a precision guidance munition assembly utilizes at least one maneuver envelope to optimally control movement of at least one canard to steer the guided projectile during flight. The maneuver envelopes optimize movements of the at least one canard that effectuate movement in either the range direction or the cross-range direction, or both. The maneuver envelope enables optimal timing such that maneuvering in one direction does not come at the expense of maneuver authority in the other direction.
(FR)
La présente invention concerne un projectile guidé comprenant un ensemble munition à guidage de précision qui utilise au moins une enveloppe de manœuvre pour commander de manière optimale le mouvement d'au moins un canard pour diriger le projectile guidé pendant le vol. Les enveloppes de manœuvre optimisent les mouvements dudit canard qui effectue le mouvement dans la direction de visée ou dans la direction de distance latérale, ou les deux. L'enveloppe de manœuvre permet une synchronisation optimale de telle sorte que la manœuvre dans une direction ne se produit pas au détriment du pouvoir de manœuvre dans l'autre direction.
