Blended missile autopilots (20) for a missile (11) employing direct lift and tail controlled autopilots (22, 21) coupled by way of a blending filter (24). The blended missile autopilots (20) have movable tails (13) aft of the center of gravity of the missile (11) and side force thrusters (15) or movable canards (14) mounted forward of the center of gravity, and that are controlled using the direct lift and tail-controlled autopilots (22, 21). Lift is generated from the tails (13) and side force is generated by the thrusters (15) or canards (14), such that the body of the missile (11) maintain zero angle of attack and generates no lift. The present invention thus combines the fast response of a direct lift autopilot (22) with the high acceleration capability of a body lift autopilot (21), and blends the two using the blending filter (24) to achieve improved performance.

Autopîlotes intégrés (20) pour missile (11) utilisant des autopilotes d'empennage et de portance commandés directement (22, 21) couplés par un filtre d'intégration (24). Les autopilotes intégrés pour missile (20) ont des empennages mobiles (13) en arrière du centre de gravité du missile (11), des propulseurs latéraux (15) ou des plans canards mobiles (14) montés en avant du centre de gravité et qui sont contrôlés par les autopilotes d'empennage et de poussée commandés directement (22, 21). La portance est générée par l'empennage (13) et la force latérale est générée par les propulseurs latéraux (15) ou les canards (14), de sorte que le corps du missile (11) conserve un angle d'attaque nul et ne génère pas de portance. La présente invention combine la réaction rapide d'un autopîlote (22) et la capacité de forte accélération d'un autodirecteur de portance de corps (21), et intègre les deux à l'aide du filtre d'intégration (24) afin de donner une performance accrue.
