Abstract: Sonobuoy apparatus which fits into an A sized canister for use in the water environment. The apparatus includes an array of telescopic arms connected by hinges to a housing which contains receiver transducer electronics. An acoustic projector bears against projections on the last arm section of each arm such that it will cause the nested arm sections to extend while dropping through the water. When the canister falls free, an arm deployment arrangement causes the arms to assume a horizontal orientation. These deployed arms carry receive transducers for detecting acoustic echos from a potential target.

Abstract: An air-launched sonobuoy, particularly useful for under-ice surveillance, rries a descent-retardation parachute whose lanyards activate a surface float during descent. Upon impact into an ice region, a slip-rod is jarred loose from the cannister top thus freeing the surface float, and its RF antenna, to remain above the ice while the remainder of the components deploy.

Abstract: An apparatus for tensioning a subsurface float line and the like during doyment of the line and thereafter includes a capstan rotatably mounted and located in a liquid medium, the capstan having a bore extending from one end of the capstan to the other end, the bore including a plurality of pump blades for moving the liquid through the bore when the capstan is rotated, the capstan also including turbine blades located around the circumference of the capstan and adjacent both ends of the capstan, the capstan also including a circular surface interposed between the turbine blades for communicating with the line to be tensioned. The pump and turbine blades do work when the capstan is rotated thereby creating a counter rotational (drag) force that tensions the line during and after deployment.

Abstract: An improved, multi-store dispenser is described which uses a solenoid and ring combination to eject individual stores after an electrical pulse is sent from the transporting aircraft. As each store is loaded into the dispenser, the loading action forces a spring into a compressed mode and a latch is closed to prevent expulsion. An electric pulse trips a solenoid, which in turn causes the latch to release, thereby allowing the store to be ejected.

Abstract: A submarine-launched, ice-penetrating sonobuoy is disclosed. The buoy is pedo-shaped with a collapsible obturator tail-fin section removably attached at the tail-end, standard electronics in a mid-section and an explosive nose cone at the front. Immediately after launch, the tail-fin section expands to exert a drag on the buoy to halt any forward motion. The tail-fin section is discarded and the nose cone and mid-section portion rise until the nose impacts the underside of the ice. Upon impact, a pre-selected "shape" charge ruptures the ice and an a spring-antenna, connected to the mid-section, is raised through the hole.

Abstract: A launch-chute extender is disclosed that snap-fits onto the end of a buoy ontainer in an aircraft that carries stores internally. This extender, by adding its tubular configuration to the end of the buoy container, provides guiding clearance to selected stores to enable them to exit from the underside of the aircraft without becoming jammed.

Abstract: An improved store launching device is disclosed wherein the inside of a sdard sonobuoy launch container is modified to accept, and properly dispense, only one smaller and lighter store. A positioning ring is fitted securely onto the inner walls a preselected distance from the discharge end to provide a seat for a perforated obturator. A slotted pressure relief ring, with the edge adjacent the obturator having a biased cut of a predetermined angle therein, is placed adjacent the obturator and the discharge end of the container to surround the store.

Abstract: The disclosure shows a multi-store, electrically-operated sonobuoy launcher hat is connected to the sonobuoy launcher power system of the aircraft. The sonobuoys are sequentially stacked inside the launcher and current switching and blocking means regulate and direct pulses from a switch in the aircraft to ensure individual, single sonobuoy launches.

Abstract: This invention comprises a multi-store, gas-fired launcher that fits into, nd is electrically connected with, a transporting vehicle and that contains sequentially-stacked assemblies that generate sufficient gas force to discharge an individual store. An electrical pulse from the transporting vehicle cause a sequencer in the launcher to divert the charge to a burn resistor. At burn-out, a spring-activated striking arm punctures a CO2 bottle which provides sufficient gas pressure to force the store out of the launcher.

Abstract: A multi-store launcher has each store in a stacked sequence releasably held y a swinging paddle assembly against the ejection force of negator springs. Each paddle assembly carries a burn resistor that is wired to maintain the paddles in a locked position. A pneumatic pulse from the transporting vehicle causes electronic circuitry to make the resistor fail, freeing the paddles to open away from the store and thereby allowing it to be ejected by the negator springs.

Abstract: This invention comprises a multi-store, electrical pulse initiated launcher hat fits into, and is electrically connected with, a transporting vehicle and that contains sequentially-stacked assemblies. An electrical pulse from the transporting vehicle causes a resistor with the least value to transfer the electric to a gas generating cartridge. The cartridge provides sufficient gas pressure to force the store out of the launcher.

Abstract: A multi-store launcher receives initial power from a pneumatic source. The ir pressure causes a shear pin to fail, thereby allowing a firing pin to ignite a gas-generation cartridge. The gas pressure is channelled to the appropriate store, which is then discharged.

Abstract: A multi-store, mechanically-actuated launcher is disclosed. Negator springs ut constant pressure on sequentially-stack stores inside a launch container and an electro-mechanical gate releases one store after another upon initiation of an electrial impulse from the transporting vehicle.

Abstract: A guideable sonobuoy is disclosed that is ejected from a moving aircraft o the free stream with a ring wing opened to guide the buoy along a predetermined flight path. While the buoy remains packed inside a launch container, the ring wing, made of spring steel, is collapsed around the nose portion thereof. Once launched, the ring wing will fly the buoy to a predetermined destination.

Abstract: A vehicle steering device is disclosed that can be joined to any air-drop, free-falling component and steers that component directly down to a pre-determined location on the earth's surface. The device is comprised of an aerodynamically-shaped housing that is joined to the front of the component, and which carries orientation means in a nose portion, high-density gravity-reaction means, and steering fins rotatably joined thereto. After the combination is dropped, at a pre-determined altitude and airspeed, the orientation means causes it to assume the most efficient aerodynamic position and then the gravity-reaction means forces the nose, which is joined to and leads the component, to dive into the earth. The reaction means are connected to the fins and force a controlled and predictable descent.

Abstract: A spin stabilized projectile containing an annulus of incendiary liquid sounding a burster tube, in which the liquid is compartmentalized to minimize rotational spin loss of the projectile due to centrifugal force effect on or anti-spin inertia by the liquid.

Abstract: A projectile having mainstream air flow directed to its surface region of rmal air non-attachment during operational flight and in which drag frictional forces in the laminar flow boundary layer region are minimized to produce maximum range.

An aluminum cartridge case, carrying a gas generating charge, has a retainer secured in its rearward end. The retainer has a base portion containing a percussion primer and a cylindrical sidewall portion containing the delay ignition unit that includes a spool having ignition train elements in its end flanges and a burnable fuze delay wire secured to the spool flanges and interconnecting the ignition train elements. The spool and retainer base portion are longitudinally spaced to provide a cavity therebetween for precluding primer overpressurization.
