摘要:
An autonomous guided parachute system for cargo drops that divides the requirements of guidance and soft landing into separate parachutes. Said invention includes a high wing-loaded ram air parachute for guidance, a larger round parachute for soft landing, a harness/container system, flight computer, position sensors and actuation system. The system is dropped from an airplane, a predetermined period of drogue fall ensures a stable position prior to deploying the guidance parachute. The flight controller determines a heading to intersect with an area substantially above the desired target and controls the guidance parachute via pneumatic actuators connected to the parachutes steering lines to fly on that heading. At a minimum altitude prior to the systems impact with the ground the flight computer transitions the system from the fast high performance guidance parachute to a larger landing parachute by releasing the guidance parachute to static line extract and deploy the landing parachute. If the system reaches a position substantially above target area prior to the parachute transition altitude flight computer controls the system into a spiral dive or other rapid altitude dropping maneuver until the transition altitude is reached. Once transitioned to the landing parachute the system descends for a brief period unguided under the landing parachute until touchdown.

The invention relates to a sub-munition unit (1) having a warhead (2) that comprises an antenna (3) on the bow side, as seen in the direction of flight, for target acquisition, and is connected on the aft side to a releasably attached parachute cartridge (4). In order to protect the antenna (3) sufficiently against both mechanical loads and aerodynamic stresses using a simple protective device, without the function of the antenna (3) being negatively affected thereby, the invention proposes that an antenna protection cover (5) be releasably disposed on the warhead in front of the antenna (3) to protect the same, the warhead (2) comprising an operating mechanism causing the antenna protection cover (5) to be ejected when the parachute cartridge (4) is released from the warhead (2).

A parachute system is disclosed for especially ballistically deployed systems. Said parachute system comprises an unopened parachute (20), the canopy (1) of which is enclosed by a packsack (11) that has predetermined breaking points (12) in the bottom zone and a cable connection (13) or the like to the functional support (5) at the top end. When the cable connection (13) acts on the packsack (11), the latter is separated from the functional support (5) at the predetermined breaking points, and the parachute (20) is unfolded by raising the canopy (1). A stabilizing net (2) is incorporated into the parachute (20). The canopy (1), including the stabilizing net (2) and the strings (3), is connected to the functional support (5) via a stable connection (4) which comprises a steel cable lock (6), a brake (7) for the steel cable lock (6), and a steel cable (8).

The sub-munition is provided with an arming device comprising a striker member (3), movable substantially in the direction of its longitudinal axis, and a detonator (4) carried by a slide (5) movable from a first position in which the detonator (4) is located out of the path of the striker member (3) to a second position in which the detonator is brought into the path of the said member and beneath it; the striker member (3) is provided with a threaded stem (9) screwed into a threaded hole of a bush (10) movable axially on the body of the sub-munition in such a way that the striker member is brought from the said first to the said second position upon unscrewing of the stem from the threaded hole; a pair of strip form flexible elements (19) are connected to the striker mem- her (3), one end of which flexible elements (19) is fixed to the striker member (3) and each of which can be disposed, when the sub-munition is expelled from tthe projectile, in a twisted configuration in such a way that the aerodynamic forces acting on them cause a moment to be transmitted to the striker memberto unscrewthis member itselffrom the associated threaded hole.
摘要:
A dispenser system provides a means to automatically deploy systems using a controlled dispense approach capable of providing desired operational flexibility. Components such as unattended ground sensors (UGS) are deployed according to a method which includes incorporating the components into an elongated ejection system to form a payload assembly, the ejection system including axially-displaced ejector bays each for holding respective components. Each ejector bay retains the respective components until a respective ejection event upon which the ejector bay ejects the components in a radial direction. The payload assembly includes a stabilizer such as a drogue parachute that substantially prevents the payload assembly from rotating about its elongated axis. A timing sequence for the ejection events is programmed into the ejection system to achieve a desired coverage pattern of the components after deployment. The timing sequence can be chosen to result in a coverage pattern along a continuum from maximum component density to maximum total area coverage. The payload assembly is subsequently released from an aerial vehicle above the area with activation of the timing sequence, such that the ejection events occur during flight of the payload assembly at respective times after its release.

The present invention relates to a method and an apparatus for imparting, in a continuous and unbroken sequence, to such warheads (3) as, housed in a protective canister (2) are ejected out into ballistic ejection trajectories, a predetermined rotational movement in connection with the warhead (3) being ejected out of the canister (2). According to the invention, this object is attained in that the canister (2) is spun up to the desired speed of rotation by adapted gas outlet nozzles (27-30) discharging in the outer periphery of the canister (2), these nozzles being fed with combustion gases from a central combustion chamber (15) in which a propellant charge (21) is combusted and from which powder gases in the final phase of the propellant charge combustion are moreover led off for ejection of the warhead (3) from the canister (2).
