Abstract:
A cover or apron interposed between a ballute and the aft cover of a submtion for delaying deployment of the ballute and preventing the ballute from contacting the aft cover during deployment.
Abstract:
An annular spinning parachute is composed of an annular canopy symmetrical about an apex, suspension lines of substantially the same length and interconnected together at the canopy apex and extending radially outwardly therefrom across the canopy and downwardly therefrom for coupling to an object supported by the parachute, and centerlines interconnected with the suspension lines at the canopy apex and extending downwardly therefrom for coupling to the object supported by the parachute. The annular canopy includes fabric panels each having a generally trapezoidal shape defined by a pair of opposing inner and outer borders with the outer border being greater length than the inner border and a pair of opposing side borders of substantially the same length. The annular canopy also includes inner and outer lateral bands respectively extending along and connected to the inner and outer borders of the fabric panels so as to dispose the panels in circumferentially spaced relation with respect to one another upon inflation of the canopy. The inner and outer bands and spaced panels define a central opening in the canopy having thhe canopy apex at the center of the opening and a plurality of exhaust vents arranged in alternating relation with the panels between the side borders of adjacent pairs of the panels.
Abstract:
A parachute associated with an object unfolds faster in an airstream if the object is first accelerated in the direction of descent. This principle can be applied advantageously to a mine system combating military targets from the air because the time between starting from an ambush position in the terrain to the onset of searching movements in the air can be shortened.
Abstract:
Parachute ejection and recovery system for rockets which protects and permits recovery of the entire rocket after launch including means for cooling ejection gases, means for directing the cooler ejection gases for using in ejection, the nose cone and parachute therefrom during flight, and means for controlling descent of the rocket body, its nose cone and a parachute associated therewith.
Abstract:
A projectile has at two parts (3, 4) axially arranged one behind the other and mutually linked, of which at least one contains a deployable parachute (6, 6'). In order to achieve a design that ensures a smooth and reliable separation of the parts (3, 4), followed by the deployment of the parachute (6, 6'), both parts (3, 4) are mutually linked by radial bolts (19) that can be radially actuated by the gas pressure generated by at least one pyrotechnic load (15) and radially moved by the gas pressure, thus separating the two parts (3, 4). The pyrotechnic load (15) can be ignited by a fuse (9).
Abstract:
A carrier projectile for aerodynamically braked submunition which can be ejected rearwardly from the tail end of the carrier projectile while contacting a cup-shaped base of the projectile. The carrier projectile has the inner edge of the fabric of a braking sail retained within the cup-shaped recess of the base of the projectile, with the outer edge of the fabric of the sail being equipped with centrifugal masses or flyweights mounted in proximity to the opening of the cup-shaped recess in the base. Provision is made to arrange the fabric of a radially outwardly tensionable braking sail in the already available recess in the base of the projectile, the braking sail being extended through the pulling action exerted thereon from the centrifugal flyweights.
Abstract:
An AIRBOC chaff deployment apparatus comprising a canister with a wind flapttached externally to the canister and connected to a drogue chute that is housed inside the canister. The drogue chute is situated atop a main chute that is atop a release mechanism, which is atop a fuze and that is atop a chaft payload, all of which is housed inside the canister. When the AIRBOC is dropped from a plane, the wind flap extends, pulling out the drogue chute. The drogue chute in turn activates the release mechanism which frees the drogue chute to pull out the main chute to which the drogue chute is connected. The deployment of the main chute causes a force greater than 40 lbs to be applied to the release mechanism, resulting in the chaff payload being released from the canister and the fuze being activated, consequently detonating the released chaff payload.
Abstract:
Missile head to be released in an airplane cargo drop or from a flying body. The missile head has a target-sensor having a transmitter, a receiver, an antenna and an explosive charge ignitable by a target location signal. In order not to interfere with the function of the explosive charge, it is best that the antenna be located in front of the target-sensor with respect to the flight direction, while the target-sensor is located behind the explosive charge with respect to the flight direction. The connection between the antenna and the target-sensor is provided by a wave carrier filled with explosives.
Abstract:
A container 10 has a release device which comprises a flexible plate 14 and a line 17 attached to the contents 11 of the container; when a force is applied to line 17 it is communicated to plate 14 which flexes and is pulled clear of a retaining flange 13 to release contents 11. As shown, the force is applied to the plate 14 via washers 18,19 and 20. Plate 14 preferably has radially directed fingers. The container may constitute part of a rocket-launched projectile and may be used to release a parachute at a desired height, the other end of line 17 being fixed.
Abstract:
Ejection head for projectiles, rockets or the like having at least one ejection section including a carrier plate, a plurality of ejection tubes for containing active elements mounted annularly about the carrier plate, a descent controller connected to the carrier plate wherein the tubes are movable from a folded position to a spread-apart position for discharging the active elements contained therein. A locking device is provided for locking the tubes in the folded position and a spreading device is provided for spreading the tubes apart with a pyrotechnical element being provided for generating compressed gas for triggering the locking device to unlock the ejection tubes and causing the spreading device to spread the ejection tube apart.
