20120248239STEERABLE SPIN-STABILIZED PROJECTILE - A spin-stabilized projectile has a collar around the middle of its spun fuselage, longitudinally spanning a center of mass of the projectile. The collar includes lift-producing aerodynamic surfaces. Positioning the collar relative to the spinning fuselage produces a direct lift force on the projectile that may be used to steer the projectile. Since the projectile is constantly spinning, the positioning may be accomplished by a brake, such as a magnetic brake or a fiction brake, that allows the collar to be positioned substantially fixed relative to inertial space, with the collar not rotating with the fuselage about a longitudinal axis of the projectile. Since the lift force is applied close to the center of mass of the projectile, the steering occurs with no substantial change in the angle of attack of the projectile.10-04-2012

20120153070AUTOMATIC RE-INITIALIZATION OF RESONANT SENSORS IN ROCKET AND MISSILE GUIDANCE SYSTEMS - An apparatus and method improves the fault tolerance of a rocket or missile guidance system which includes a resonant sensor. When improper initialization is detected, the resonant sensor is reinitialized, repeatedly if necessary, until normal operation is achieved. Improper initialization is detected by comparing data from the guidance system with pre-specified physical limits to roll, pitch, yaw, and/or other features of the flight scenario. Embodiments can also detect a fault condition due to an error signal from a “Built-in-Test” (BIT) module. The initialization sequence initiated by the invention can be identical to the power-on sequence, or it can be a separate, reinitiating sequence. Subsequent resets are initiated as needed, for example until the burn of the rocket fuel and the associated vibrations have ceased and the resonant sensor has been successfully initialized.06-21-2012
20100270418MISSILE TRAINING SYSTEM - The present invention is directed to missile training systems, especially to those relating to the provision of a mechanism that allows missiles and similar devices to be fired at a target in a realistic, but safe, manner. The use of live fire exercises, in which army or other armed forces personnel use fully functioning weapons systems is well established. Live fire exercises can be used to provide realistic training scenarios, but also present obvious dangers. Live fire exercises present opportunities for checking that weapons systems function correctly and allow users, such as soldiers, to practice using real weapons in situations that are more realistic than firing ranges. It is known to use live missiles and torpedoes in naval training exercises and trials. For example, missiles can be fired at a ship to check the effectiveness of mechanisms for tracking and destroying such missiles. Clearly, there are substantial safety and costs issues to address before such a live firing regime is likely to be approved. A first approach for firing live missiles at a ship involves the use of a dummy ship, but crucially requires no personnel to be on board, thereby eliminating the risk to human life. This approach has clear disadvantages. A second approach involves firing a missile or other projectile at a target, such as a ship, so that the missile or projectile passes over the ship and lands on the other side. This approach enables personnel to be on board the ship and enables the on-board systems to be used in a realistic manner to attempt to destroy the incoming missile. However, there is a lack of realism. A third approach is to direct a missile towards a ship but to program its route so that it moves away from the ship immediately prior to any impact. This system also lacks realism. Other approaches exist. The present invention provides a module for attachment to an object (such as a missile), the object being adapted to be directed towards a target (such as a ship), the module comprising a control system providing an output signal indicative of whether or not said object is to be destroyed.10-28-2010
