  • Patent number: 7726243
    Abstract: A parachute flare igniter assembly includes a novel safety for arresting the motion of a slider when subjected to external forces, but allows slider motion when subjected to intended cable actuation forces. The igniter safety includes a housing, a slider, a cable and a sleeve. The slider, connected to the cable, is slidably received within the housing. The cable moves the slider by applying a cable force conventionally obtained by actuation of a parachute associated with the flare and connected to an end of the cable opposite an end connected to the slider. The sleeve is connected to the cable and is disposed between the housing and the slider, so that the sleeve will arrest the slider with respect to the housing when the cable force is not present. A flare and a method of providing a safety in an igniter assembly is also provided.

  • Patent number: 6230629
    Abstract: An IR radiating decoy for an IR seeking anti-ship missile (ASM) includes a propulsion section, safe and arming section, gas generator section, fuel tank section, and flight stabilization section to ignite and continuously maintain an IR plume for decoying the ASM away from the targeted ship. The IR radiating decoy ignites the IR plume immediately when the decoy reaches a safe separation distance from the targeted ship. The IR plume continues to be emitted as the decoy flies away, as it lands on the water, and while it floats upon the water until all the fuel is used from the fuel tank. The fuel can be changed to change the signature of the IR plume so that different ASM missiles can be drawn away from the ship.

  • Patent number: 5760330
    Abstract: A delivery apparatus (11) for full-calibre submunitions or the like payloads (12) which are coaxially stacked in its load space (19) results in a system which operates in a fault-free manner when, for ejecting the payloads (12), detachment of the load space (19) from the rocket motor (17) disposed therebehind and detachment of the ogive (14) from the opposite end of the load space (19) are each promoted by a pyrotechnic charge (28, 31), with the load space (19) being braked as a result of being positioned transversely beside the trajectory (26) of the separated motor (17) which flies further along the trajectory and past the load space in a stable configuration and with the load space (19) only then being turned by a braking parachute (23) connected to its end (22). The load space tail (18) which thereafter then faces forwardly in the direction of flight is opened by detachment of a cover (25) and the load space (19) is pulled away from the payload stack (12--12) by means of the braking parachute (23).

  • Patent number: 5661257
    Abstract: A covert, i.e., no visible light emitted, multispectral day/night target marker is disclosed. The marker emits a signature detectable in the electromagnetic spectrum including visible, near infrared, middle and longwave infrared, and radar regions. The marker is particularly useful for marking of target areas so that they can be easily detected from the ground or the air. The visible spectrum is marked by a white or colored pyrotechnic smoke generant. The near infrared region is marked by near infrared emitting photodiodes encased in a hardened polymeric molding compound. These diodes are only visible through night vision devices (image intensifiers). The middle through the far infrared regions are marked by the heat generated from the combustion of the pyrotechnic smoke generant. The smoke generant is housed in a canister having a highly emissive surface. The radar region is marked using radar chaff. The target marker is configured for use with conventional mortar or rocket delivered flare systems.

  • Patent number: 5386781
    Abstract: A parachute deployment system for use with an illuminating flare warhead propelled by a rocket motor. The system employs a compact two-stage parachute system which includes a main parachute arranged within a main parachute cover and a drogue parachute arranged within a drogue chute cover. The main parachute pack and the drogue parachute are configured to be positioned in a side-by-side, detached relationship within the warhead. An extraction line separably connects the drogue parachute pack to the rocket motor and a support line connects the drogue parachute pack to the main parachute pack such that upon separation of the rocket motor from the warhead, the drogue parachute pack is extracted from the warhead prior to extraction of the main parachute pack. Upon deployment of the drogue parachute, the drogue parachute cover remains attached to the extraction line and acts as a deflector, inducing radial forces which act upon the rocket motor to prevent it from colliding into the warhead.

  • Patent number: 5003881
    Abstract: Illuminating flare has an igniter in which a two-part inertial mass is gud for relative aftward movement from a safe position to an armed position under launching forces. One part of the mass undergoes relative forward movement to an ignition position under parachute-opening, deceleration forces while the other part of the mass is restrained from moving as far forward as the first part. This separation of the parts of the mass releases locking balls to unlock a firing pin, which stabs a primer and initiates ignition of the flare. The primer is contained in a rotor, and as the mass traverses from the safe position to the armed position it rotates and the rotor rotates with the mass. In the safe position the primer is out of communication with an ignition passage through which ignition of the illuminant composition occurs. Rotation of the rotor as the mass traverses to the armed position places the primer in communication with the ignition passage where it remains until activated by the firing pin.

  • Patent number: 4651648
    Abstract: A pyrotechnic, aircraft carried bomb such as a smoke bomb, illumination b, flare bomb and the like. The bomb comprises detachable delay and nose sections and two main body sections separable from each other and each holding a pyrotechnic charge. The tail section houses a braking parachute which is deployed by the action of a time fuze upon release from the carrier aircraft. The tail and nose sections further house each a main parachute associated each with one of the main body sections. After a certain delay the deployed braking parachute starts an ignition train which causes ejection of the tail and front sections, deployment of the main parachutes, separation of the two main body sections from each other and ignition of the pyrotechnic charges therein. The two main body sections parachute down and reach the ground in soft landing with the pyrotechnic charges burning during the descent and, if desired, they may be arranged to continue to burn for a while after landing, e.g. in case of a smoke bomb.
