  • Patent number: 9677864
    Abstract: A closed, self-contained ballistic apogee detection module for use in a projectile, such as a rocket, mortar round, or artillery round, fuses data from multiple built-in sensors, such as an accelerometer, a magnetometer, and a gyroscope, and processes the data using a microprocessor through a custom quaternion extended Kalman filter to provide accurate state and orientation information about the projectile so as to accurately predict apogee. The module outputs a signal indicating apogee detection or prediction which they projectile uses to initiate fuze arming, targeting control, airbody transformation, maneuvering, flow effector deployment or activation, payload exposure or deployment, and/or other mission activity. Because the system and method of the invention does not rely on external environmental data to detect apogee, it need not use a pressure sensor and can be completely sealed in and closed without requiring access to air from outside the projectile for barometric readings.

  • Patent number: 7178462
    Abstract: A projectile includes members that deploy upon impact with a target. The projectile includes a nose piece with a portion that shears off upon impact with the target, causing the nose piece to be pushed inside the projectile. As the nose piece is pushed inside the projectile, the nose piece pushes on members that deploy outwardly and lock into place, thereby greatly increasing the damage done to the target. The projectile is easily assembled by placing the two members through an axial cylindrical hole into slots, then placing the nose piece into the axial cylindrical hole. The deployable members are held within the body of the projectile in flight, and only deploy when the projectile strikes a target, greatly increasing the damage to the target.

  • Patent number: 7163176
    Abstract: A 2-D correction system uses intermittent deployment of aerodynamic surfaces to control a spin or fin stabilized projectile in flight; correcting both crossrange and downrange impact errors. Intermittent surface deployment develops rotational moments, which create body lift that nudge the projectile in two-dimensions to correct the projectile in its ballistic trajectory. In low spin rate projectiles (“fin stabilized”), the rotational moment directly produces the body lift that moves the projectile. In high spin rate projectiles (“spin stabilized”), the rotational moment creates a much larger orthogonal precession that in turn produces the body lift that moves the projectile. The aerodynamic surfaces are suitably deployed over multiple partial roll cycles at precise on (deployed) and off (stowed) positions in the cycle to nudge the projectile up or down range or left or right cross range until the desired ballistic trajectory is restored.

  • Patent number: 7007607
    Abstract: A hinged explosively formed projectile warhead system eliminates exposure of soldiers to harm in wall breaching operations by providing a lethal mechanism that can be deployed at safe distances, simultaneously breaching a man-sized hole and removing one or more rows of rebar in reinforced concrete structures or barriers. The warhead system employs both a missile system and explosively formed projectile warhead technology delivered to the target from a tube launched platform. A set of warhead arms is attached to the aft end of a missile body by means of a set of hinges. The warhead arms are initially folded against the missile body. After launch of the warhead system, the warhead arms fold away from the missile body. The angle at which the warhead arms are folded from the missile body determines the area of a hole breached by the warhead system in a reinforced concrete target.

  • Patent number: 6626077
    Abstract: An intercept device for flying objects made of a light-weight, packable structure made of a pliable, tear resistant material that can be expanded to a large web-like structure by means of a deployment device, into the path of a flying weapon. To capture, hold and reduce the velocity of intercepted flying objects, activatable resistance bodies are incorporated into uniformly distributed masses that are connected to the perimeter of the web like structure. Contractable sections of the web, made of cable-like structures, connected to perimeter masses, act as drawstrings upon collision with flying object. This causes closure of the web around the flying object as a result of the mass's inertia and added resistance from deployable resistance structures that place tension on drawstring structures of the web. The flying object is subsequently captured within the web, held secure and it's velocity rapidly reduced.

  • Patent number: 6240849
    Abstract: A projectile attachment is disclosed that has open-biased arm members that can be either mounted directly onto the projectile base or may be mounted to a mutual connection means which is then attached to the projectile base. The arms are compressed into a restrained position so that they may be inserted into the casing of the bullet. Upon firing, the arms extend to the unrestrained position. Upon impact the projectile penetrates the target then the extended arm members engage the target surface to cause widespread damage while slowing the projectile. The members may optionally have hook-like ends.

  • Patent number: 5368255
    Abstract: A missile includes a missile body having a nose, a tail, and a center of gravity therebetween. A plurality of blades are arranged symmetrically around the missile body at a location between the nose and the center of gravity. The blades are deployable from a stowed position folded flat against the body of the missile to a deployed position extending outwardly from the body of the missile, and are mounted so as to be biased toward the deployed position. A retaining wire extends circumferentially around the body of the missile and captures the blades thereunder. The retaining wire may be controllably severed by a pyrotechnic device to release the blades to extend to the deployed position. The extended blades cause the missile to tumble from a first stable orientation to a second stable orientation, permitting it to be quickly pointed in the opposite direction without expenditure of fuel.

  • Patent number: 5237926
    Abstract: By means of multi-member, spreadable righting assemblies, a supporting area can be enlarged in connection with a rightable drop unit, the torque required for righting can be reduced, and the stability can be enhanced. In order to provide that a base of each righting assembly does perform the desired, defined movement, at least one guide member (for example a parallel guide means) is included. The afore-mentioned improvements can be attained practically without an increase in the volume or in the weight of the drop unit.

  • Patent number: 5140909
    Abstract: A projectile with rear and front sections able to deliver payloads of submunitions contained inside the projectile after separation of the rear from the front section. The rear section is fitted with an assembly of thin blades. When both sections are assembled, the blades are partially in the rear section and partially in the front section, and when the two sections are separated, the blades spread out. The assembly is such that the length of blade that spreads out is greater than the length of blade that was in the front section before separation of the two section.

  • Patent number: 5069136
    Abstract: A two-stage release self-righting mechanism and method employ a pair of primary and secondary releasable holder assemblies which respective hold upper and middle portions of leaf spring arms in a stowed position against the side wall of a load such as a submunition launcher tube. The primary holder assembly is released first which permits release of a portion of the energy stored by the spring legs, causing them to partially extend from the stowed position to a partially deployed position and partially erect the submunition. Then, a short time later, the secondary holder assembly is released, permitting release of the remaining energy stored by the spring legs, causing them to fully extend to a fully deployed position and complete the erecting of the submunition.

  • Patent number: 4958566
    Abstract: A braking mechanism for a rotating flying object. The braking mechanism includes a planar fabric sheet having a central attachment base portion that can be secured to the flying object. The fabric sheet is adapted to be stored in a folded-up readiness state in the flying object, and, when released and unfolded, is adapted to form a braking surface that encircles the flying object. The braking mechanism further includes a plurality of reinforcing strips that each extend radially between the central attachment base portion and an outer rim of the braking mechanism and are distributed about the periphery of the latter. Each reinforcing strip extends from the central attachment base portion to the rim and back again to at least partially form two layers and to form loop-like pockets at the rim, with centrifugal weights being disposed in these pockets.

  • Patent number: 4798143
    Abstract: A warhead adapted to be mounted to a conventional missile fired from anti-tank weaponry is formed with a piercing cone secured to a base containing a source of knockout gas and an actuator assembly. Upon piercing an aircraft fuselage, a collar encircling the cone translates rearwardly causing deployment of panels pivotally secured to the base portion and connected to the collar via connecting rods. Movement of the collar into wedging contact with the base of the piercing cone deploys the panels to their maximum extended position and simultaneously actuates the trigger assembly causing the knockout gas to be delivered into the aircraft interior through the piercing cone projecting through the fuselage into the interior.
