  • Publication number: 20100230531
    Abstract: Systems and methods are described for deterring birds from flying into airspace above airport runways. The system features at least one mortar for firing a pyrotechnic device to produce a light and sound display for the purpose of disturbing, frightening, and harassing birds so as to deter them from flying into airspace above and in the vicinity of an airport runway. The mortars of the system can be installed on a mounting platform capable of being securely connected to the ground or a ground surface substrate or to a vehicle. Fixed position, movable and portable embodiments of the system may be created and used. The light and sound display produced by the exploding pyrotechnic devices can be varied to prevent the birds from becoming desensitized to the sounds and visual effects of the system. The system may also include deterrent chemicals.

  • Publication number: 20080289530
    Abstract: An airborne device such as a model rocket or balloon is provided with a light source and/or a sound source that makes the rocket visible during ascent, descent and recovery at night. The sound source is provided to assist in day time recovery. The light source may be located in a transparent or translucent nose cone section of a rocket or otherwise attached adjacent or in a balloon to assist in operation and viewing. The light source may include a timing or flashing feature to make the airborne device or rocket more visibly distinct during flight and recovery. Additional signaling and informational light sources may be added to other parts of the rocket and to the ground mounted launch apparatus to announce launching and/or improve the night time viewing. One form of the rocket system uses a count down feature with lights on the launch structure to signal when blast off will occur.

  • Patent number: 4226185
    Abstract: A projectile having a payload, a first brake system and a second brake system at one side of the payload. A first explosive charge and a second explosive charge, separated from one another by a drive disk, are arranged at the other side of the payload and surrounded by a hollow projectile jacket.In order to render as simple as possible the construction of such projectile and in order to make available for the payload as large as possible part of the cross-section of the projectile, there is provided a latching or locking location at the projectile jacket for a container and the payload. The container and payload can remain in the projectile jacket as long as the initially effective brake system brakes the projectile. For slowly lowering the payload with the other brake system the payload leaves the latching location and thus the projectile jacket.

  • Patent number: 4209151
    Abstract: A banner in the form of an elongated sheet of flexible material is attached to an air dropped sonobuoy for stabilization of the sonobuoy during descent as well as for descent speed control, entry angle control, and wave action damping once the sonobuoy is floating at the surface of the ocean. The banner is roller furled and stored on top of the sonobuoy. When the sonobuoy is dropped, the banner unrolls and streams out behind the sonobuoy during descent. It is a feature of this drogue apparatus that it is deployed by the time that the sonobuoy has descended a distance corresponding approximately to the length of the banner. The banner is not released when the sonobuoy hits the water in order to enable it to stream out over the surface of the water to provide wave damping action.

  • Patent number: 4023495
    Abstract: An improved twist brake for the separable payload of a twist or spin-stabilized flare or smoke projectile is described. A pair of pivotable wings, secured at one end to a portion of a central shaft of the payload, is normally engaged by the inner surface of a guide shoe which prevents contact of the wing with the separable housing of the payload. Cooperable projections and slots on the guide shoe and the central support shaft prevent substantial axial and circumferential movement of the shoe, while permitting outward movement of the wings and the guide shoes when the payload separates from the housing. During such separation, the guide shoe is also separated from the wings so that the latter can pivot to their maximum extent to provide an optimum rotational braking action on the payload.

  • Patent number: 3964396
    Abstract: A release mechanism for use with an air-dropped store having a timed firing echanism which can be set for different time intervals. Action is initiated by a plurality of dynamic pressure sensing fins which, upon actuation, first unlock an inertia locking arm and then the fins impart a rotation to the store which rotation, in turn, causes the locking arm to pivot and initiate a timer. The timer, in turn, initiates separation of the release mechanism from the store.

  • Patent number: 3964700
    Abstract: An elongated, cylindrical case has an intermediate partition dividing it into a canister and a housing. A parachute is attached into the housing with deployment means releasable by a timer. After a predetermined time has elapsed, the timer withdraws radial pawls to release an end cap from the housing, allowing the parachute to be deployed. The canister is equipped with a special end cap capable of hermetically sealing the canister so that it may convey any of a variety of cargo via airdrop. This end cap is essentially a cylinder, recessed at both ends. A disk is held adjacent the inner end of the cylinder by a center post that passes through central holes in the cylinder by the disk and is pivoted to a plurality of radial pawls that may be extended or withdrawn by rotation of the center post, so that they may engage a shoulder in the end of the canister. The center post is equipped with means for locking it in one position so that the end cap cannot be removed by accident from the canister.
