Dual-control scheme for improved missile maneuverability

Abstract

A comparative dual-control strategy actuates forward and aft control devices simultaneously to significantly improve a missile's maneuverability/dynamic capability. A substantial, and measurable, operational effect of the inventive control strategy is a dramatic improvement in a missile's divert capability. To effect a maneuver in accordance with the inventive strategy, a missile's aft fins are initially deflected to generate a force OPPOSITE that conventionally used (pushing the missile's tail in the direction of the commanded maneuver) which simultaneously actuating forward thrusters to also push the missile's nose in the direction of the commanded maneuver but at a faster rate than the tail section. This causes the missile body to simultaneously rotate and translate in the direction of the commanded maneuver. Once a sufficient amount of aerodynamic force develops due to body rotation, the aft fins are deflected to generate a force that opposes the commanded maneuver to maintain a moment on the missile body and complete the commanded maneuver. An important benefit of cooperative dual-control strategy is that the missile begins to translate in the direction of the commanded maneuver immediately (conventional isolated aft control schemes do not accomplish this) and at a faster rate than is possible with either isolated forward control devices or an intuitive dual-control approach.

AI Technical Summary

Benefits of technology

The present invention relates to a new method for controlling the movement of a missile during flight. It involves two types of controls: one that affects the front part of the missile, called the forecontrol, which can change its position relative to the other parts of the missile; and another that affects the back part of the missile, called the aftercontrol, which can adjust how much air it generates. By combining these two kinds of controls, the missile becomes more easily controlled and able to move around quickly. One advantage of this technique is that it allows the missile to start moving sooner and at higher speed compared to previous methods. Overall, this technology improves the ability of the missile to make precise movements during flight.

Problems solved by technology

The technical problem addressed in this patent text is finding ways to improve the maneuverability of missiles through the use of advanced control techniques. Specifically, the text describes methods for increasing the speed and stability of the missile during different phases of operation. One method involves using a duel-control design with both front and aft control devices acting together to optimize the movement of the missile. However, there have been difficulties in accurately allocating the responsibilities of each control mechanism due to the challenge of coordinating their actions. Another method mentioned is the intuitive approach, which scales the controls based on the size of the vehicles involved.
