    摘要： A method for operating a thrust-generating supercavitating projectile involves launching the projectile at a velocity above the minimum required to maintain supercavitating movement, delaying initiation of thrust until the projectile slows to a velocity that is near that minimum velocity, and then applying thrust to maintain the near-minimum velocity until a target is reached.

    摘要： An apparatus for sealing the barrel of an underwater gun between firings is disclosed. The apparatus comprises a magnetically-attractable water-impermeable disk. Via operation of a drive system, the disk is movable between a sealing position, wherein it prevents water from entering the barrel by moving into alignment with the first bore, and a firing position, wherein the first water-impermeable disk moves out of alignment with the first bore.

    摘要： A surface ship, deck-launched anti-torpedo projectile is disclosed. The projectile has a blunt-end nose to create a cavitating running mode. The nose has a gradual, stepped, right-circular cylindrical or conic geometry. In some embodiments, the projectile includes a plurality of tail fins that are dimensioned and arranged to be within the generalized elliptical cavity that shrouds the projectile in the cavitating running mode.

    摘要： A technique for controlling the pitch of a supercavitating projectile is disclosed. For example, the illustrative embodiment controls the pitch of a supercavitating projectile by shifting its center of gravity. The center of gravity of the projectile is shifted by moving a ferromagnetic mass inside the projectile forward or backward, depending on the desired pitch. In some embodiments of the present invention, the position of the ferromagnetic mass is directed by a controller that has a predetermined trajectory stored in its memory.

    摘要： A projectile having a cavity-running mode is provided with a means for changing the diameter of its nose. Based on changed conditions, the diameter of the nose can be actively reduced or increased, as required, to maintain a desired value for the nose-to-body ratio of the projectile.

    摘要： A mechanism for empirically deriving the values of the damping ratio and frequency of the mechanism driven by a servo-controlled control system is disclosed. In accordance with the illustrative embodiment, the values of the damping ratio and frequency are continually re-generated based on empirical data derived from sensor feedback of the maximum-amplitude switch and the linear second-order servo. Because the values of the damping ratio and frequency are generated from empirical data, it is not necessary that they be known, and because the values of the damping ratio and frequency are continually re-generated, variances in their values are continually noticed and compensated for.
