    Abstract: The illustrative embodiment provides bumpers which are roughly shaped like skis that face towards the air-water boundary of the air cavity. When the projectile fishtails and one or more of the bumpers come into contact with the air-water boundary, the water imparts torque and a rebounding force to push the projectile completely back into the air cavity. Furthermore, because the bumpers are shaped roughly like skis and not like knives, the bumpers do not penetrate the water or create unnecessary water drag.

    Abstract: An undersea vehicle having both low emitted noise and low reflectivity is provided. The undersea vehicle has a hollow cylindrical hull with all components, sensors, electronics, motors, and other internal components with the exception of the propellers, located within the shell of the cylindrical hull. The hollow center of the hull provides a duct and propeller configuration with the shaping of the inlet tube designed to reduce forward noise transmissions, such as reflected active sonar signals and emitted noise. The internal duct gradually constricts to a throat section and thereafter diverges to an output section where dual counter-rotating propellers are located. The result is that most of the internal turbulent flow and the propeller noise is located behind the throat and is thereby reflected in the aft direction. Steering of the vehicle is accomplished by canting the leading edge intake section and the duct exhaust section.

  • Patent number: 5824946
    Abstract: A search angle selection system generates a search angle for a torpedo in sponse to a number of inputs. Initially, the system bounds the region to be insonified. The system determines the search angle which best insonifies the region from the surface down to the target's keel depth out to the maximum acquisition range of the torpedo, for each search depth accounting for the torpedo's attack angle. The system determines a set of attainable aimpoints along the surface which are based on the environmental and weapon parameters. It then finds rays which intersect the aimpoints and uses the ray angles to determine an optimal beam steering angle. For each search depth, the system categorizes the sound speed profile between the search depth and the surface, and determines the maximum range that can physically be reached from the search depth. Using the maximum range and the weapon's range gate, a maximum aimpoint is established.

The system determines the search angle which best insonifies the depth band, that is, the region between the upper depth bound and the lower depth bound, for each search depth, accounting for the weapon's attack angle, including search depths which are not in the depth band itself. For each search depth, the system determines the relative depth separation of the search depth from each of the bounds, and based on this separation an aimpoint which projects from a reference plane through the torpedo is chosen at the depth of each bound. The aimpoint is selected from a table of empirically-determined values.

    Abstract: A system of articulation units is inserted between sections of a standard lindrical underwater vehicle, such as a torpedo, to provide a highly maneuverable vehicle. Each articulation unit consists of two bulkheads connected by a spherical joint which allows rotation about the joint. The bulkheads are connected to adjacent torpedo sections by means of standard joint bands. A number of hydraulic actuators are spaced radially about the spherical joint between the bulkheads. By selectively activating the actuators, the joint bends the vehicle about its longitudinal axis. The pressure of the surrounding medium against the moving vehicle causes the vehicle to turn in the direction of the bend. Depending on the actuators activated, the vehicle can be made to bend, or turn, in any direction, making for a highly maneuverable vehicle.

    Abstract: A method and system for improving the reliability of an electronic system formed of subsystems which perform different functions. The electronic system is analyzed to determine which of the subsystems is most likely to cause a system failure and these subsystems are targeted for monitoring and/or correction by a microcontroller unit. The microcontroller unit monitors the inputs and outputs of the targeted subsystems and determines when an output is inappropriate for the corresponding input. When an error is detected, an error code is stored in memory for future reference. When the microcontroller is in a correcting mode, open collector drivers are used to make corrections for an error in a digital output. Where the error generated is for an analog output, a digital to analog converter circuit and voltage followers are employed to impress the correct analog signal on the inappropriate output.

  • Patent number: 4732100
    Abstract: An interior actuation system for controlling an exterior control surface of a torpedo or the like which has an afterbody with radial inlet vanes defining inlet liquid passages to the propellers of the torpedo. A linear actuator is mounted in the afterbody. A bell crank is connected at one end to the linear actuator and extends radially outwardly therefrom through one of the inlet vanes. A driving connection, including a link arm connected at one end to the opposite end of the bell crank, extends longitudinally from the bell crank through the afterbody outside the liquid passages and operatively interconnects the control surface to the linear actuator.

  • Patent number: 4429652
    Abstract: For enhancing the maneuverability, speed, survivalbility, and targeting accuracy of a torpedo moving below the surface of a body of water, ultrasonic vibrations are set-up at the exterior of the torpedo hull, using controlled piezoelectric crystals to generate the vibrations in the 5-50 KHZ and 5-30 KW frequency and power ranges. Ways are disclosed for operating the piezoelectric crystals to steer the hull without need for mechanically moving parts such as flaps or fins.

  • Patent number: 4392443
    Abstract: Propulsion means of undersea vehicle comprises a pair of counter-rotating w speed impellers driven from a spider shaft rotating at relatively high speed. The reduction is accomplished by a variable speed reducing and torque transmitting device which allows infinite resolution for speed control including a zero speed setting while maintaining a constant high speed at the input spider shaft. Attitude of the vehicle is controlled by a plurality of regulated inlet ports and roll control is regulated by increasing the speed of one impeller and decreasing the speed of the other. The sea water utilized for the attitude is also used for propulsion. Control systems within the vehicle utilize and electro-pneumatic-hydraulic system complex.

  • Patent number: 4391474
    Abstract: A seal for a thrust shaft in a body wherein the body has a bore and a counterbore, the bottom of the counterbore providing a shoulder for the thrust force of the shaft. The seal includes a bearing sleeve which is slidably mounted on the shaft, the bearing sleeve having a static O-ring which seals the interior of the sleeve to the shaft and a flange which extends into the counterbore. Provision is made for radially fixing the bearing sleeve to the shaft. A ring-shaped seal housing is mounted about the shaft below the bearing sleeve and extends into the counterbore, the seal housing having an interior dynamic O-ring sealing the housing to the shaft and an exterior static O-ring which seals the housing to the counterbore.
