  • Patent number: 8887614
    Abstract: A submarine buoyant payload launcher system includes support rails extending longitudinally along an interior surface of a submarine missile capsule. A plurality of hold downs are spaced along the length of each rail and are retractable into the support rails. Once a payload is in position within the rails, the hold downs adjacent to the top end of the payload are rotated to their closed position, so as to contact the payload. Another payload can then be loaded within the rails until the payload contacts with the closed hold downs. As in the case of the first payload, the hold downs adjacent to the top end of this next payload are rotated to their closed position. Multiple payloads can be loaded within the rails in this manner.

  • Patent number: 8662441
    Abstract: A system for launching an unmanned aerial vehicle (UAV) payload includes a launch tube, liquid rocket, and launch control assembly. The rocket is positioned in the launch tube and contains the UAV payload. A booster assembly may include a canister partially filled with liquid. A gas cylinder is filled with compressed gas. The liquid is pre-pressurized by the gas or mixed with the gas right before launch such that, upon launch, liquid and gaseous thrust stages launch the rocket to a threshold altitude. The UAV payload deploys after reaching the threshold altitude. Optional stability tubes may be connected to the launch tube, which may be buoyant for water-based operations. An optional tether may be connected to the liquid rocket for arresting its flight prior to reaching apogee. The UAV payload is not launched directly by the gas/liquid mix. A method of launching the UAV payload is also disclosed.

  • Patent number: 7775148
    Abstract: Launching payloads at high velocity uses high-pressure gas or combustion products for propulsion, with injection of high pressure gas at intervals along the path behind the payload projectile as it accelerates along the barrel of the launcher. An inner barrel has an interior diameter equal to the projectile diameter or sabot containing the projectile. An outer casing surrounds the inner barrel. Structures at intervals attach the outer casing and the inner barrel. An axial gas containment chamber (AGC) stores high pressure gas between the inner barrel wall, the outer casing wall, and enclosure bulkheads. Pressure-activated valves along the barrel sequentially release the high pressure gas contained in the AGC in to the barrel to create a continuously refreshed high energy pressure heads behind the projectile as it moves down the barrel. A frangible cover at the exit end of the barrel allows the barrel to be evacuated prior to launch. The launcher is rapidly recyclable.

  • Patent number: 7337741
    Abstract: A system is disclosed for pre-positioning a canister assembly at an undersea location. A transporter deploys to and releases the assembly proximate to the desired location. Once the assembly has fallen a safe distance after release, spring bands of the assembly are released by the action of lanyards of the transporter. The release allows anchor plates on each end of the assembly to separate from the assembly thereby dragging the assembly to a seafloor with the assembly buoyant at the undersea location. A vehicle deployment from the assembly is actuated by an acoustic receiver that causes a release device to release a normally compressed spring thereby allowing the spring to expand. During expansion, water is drawn into the assembly through flow ports to force a plunger plate with the water to act on a vehicle to deploy the vehicle out of a deployment tube of the assembly.

Ends of the tubular member are closed by expellable members. Flood valves are located on the expellable members and, on activation, allow flooding of the tubular member by external fluid. A propellant device and an object contact member are disposed within the tubular member. When the propellant device is activated, the object contact member moves the object. These actions are controlled by a control device which first causes the flood valves to enable fluid to flood the interior region. Next, the control device causes the expellable members to be expelled from the tubular member. The control device then causes the propellant device to generate gas in a predetermined manner launching the object from the tubular member.

In the retracted position, the outer nose section and one or more intermediate nose sections are retracted generally within the base nose section. In the deployed position, the outer nose section and intermediate nose sections extend outwardly from the base nose section and interlock proximate the edges of the nose sections to form the deployed nose.

  • Patent number: 6371003
    Abstract: The disclosure relates to an enclosure for installation in the seabed comprising an elongate container for holding a payload. The container has a plurality of passages extending lengthwise of the container and an impeller at the lower end of the container for drawing water through at least one or said passages to form a slurry with the material of the seabed and for discharging the slurry at the upper end of the container into the surrounding water. The enclosure has inner and outer concentric passageways extending lengthwise thereof and said impeller has a blade or blades extending across the inner and outer passageways. The blade of the impeller has a first portion pitched to draw water down one of the passageways to the lower end of the container and a second portion pitched to discharge slurry up the other of the passageways to the top of the container.

  • Patent number: 6305263
    Abstract: An appended pod underwater gun mount for a submersible host vessel includes a strut member having a base end fixed to an outer hull of the submersible host vessel and a distal end protruding outwardly from the host vessel, the distal end being angled with respect to the base end, and an ammunition housing moveably fixed to the distal end of the strut member. A train control mechanism is positioned between the strut member and the ammunition housing for controlling the horizontal rotation of the ammunition housing with respect to the host vessel, and a tilt control mechanism is positioned between the strut member and the ammunition housing for controlling the vertical rotation of the ammunition housing with respect to the host vessel. A flexible boot is connected to the ammunition housing and surrounds each of the train control mechanism and the tilt control mechanism to protect the mechanisms from an underwater environment.

  • Patent number: 6286410
    Abstract: The invention features a self-contained enclosure-plus-enclosed contexture and the implementation thereof in a multi-phase launching system, according to which the waterborne first phase entails naturally (buoyantly) induced motion, and at least the airborne second phase entails artificially (technologically) induced motion. Typical inventive practice provides a launch canister which is exteriorly configured to be hydrodynamically efficient while moving buoyantly upward in response to hydrostatic pressure, and which has a chamber for stowing an air vehicle. The inventive vehicle-stowing canister is released underwater so as to be buoyantly propelled upward and into the air, at which time the air vehicle is mechanistically propelled (e.g., boosted), in response to which the canister becomes disjointed cooperatively with the uncoupling of the air vehicle from the canister. The air vehicle continues to propulsively ascend, the canister's nose cone and main body gravitationally falling to the water below.
