Definitions
- ABSTRACT 22 ga 3
- An improved airborne dispenser for releasing radar reflective [5! l in! CI 565d 83/00 material, pyrotechnic flares and the like includes a core [58] Fieid 18 B 18 member for storage of the material to be released and a pro- 116105. [69/28 tective casing which is removed in flight to allow for optimum dispersion of the material released.
- an airborne dispenser comprises a core member and a surrounding multipart casing member, the core member having at least two cavities formed in that surface thereof confronting the casing member, each cavity being closed by a part of the casing member, one or more articles housed in each cavity, releasable means securing each part of the casing member to the core member and means to release the parts of the described, member to sequentially open the cavities.
- the core member having at least two cavities formed in that surface thereof confronting the casing member, each cavity being closed by a part of the casing member, one or more articles housed in each cavity, releasable means securing each part of the casing member to the core member and means to release the parts of the described, member to sequentially open the cavities.
- the casing member is of circular cylindrical form with the division between the parts fliereof extending in the axial direction of the casing member.
- the core member is conveniently of cruciform shape, with the cavities for the article or articles defined between adjacent arms of the cross and the surrounding arcuate part of the casing. With the arrangement described, the cavities extend axially of the casing member and these cavities may be internally divided into lengths corresponding to the size of the article or articles (e.g., corresponding to the length of the filaments or foil) to be packed in the cavities.
- the parts of the casing member may be hingedly attached at one end to the core member and secured at the other end to the core member by means which can be explosively released.
- explosive means for releasing the parts of the casing member it is possible to stagger the moment of release of each casing part relative to the other casing parts by employing delay fuses to the separate explosive charges.
- FIG. I is a part sectional side elevation of the dispenser, and FIG. 2 is a section on the line II-Il or FIG. 1.
- the dispenser comprises a core I surrounded by a four-part c lindrical casin 2.
- the core I is fabricated om end discs and 4 of circular cross-section and a central region 5 of cruciform cross-section (see FIG. 2).
- the parts of the casing 2 are hingedly attached to the end disc 4 and are secured to the end disc 3 by means of explosively destructible pegs (not shown) housed in passages 6 in the end disc 3.
- the parts of the casing 2 lie in contact with the discs 3 and 4 over their entire circumferences but by virtue of the crucifonn shape of the central region 5 between the end discs, a plurality of axially extending cavities 7, 8, 9 and I0 are formed.
- Each cavity contains a bundle or radar-reflective filaments II, the cavities 7, 8, 9 and 10 being subdivided axially of the casing 2 by partitions 12.
- the bundle of filaments 11 are placed in the appropriate cavity with the elongate direction of the filaments axially disposed relative to the dispenser. To facilitate the insertion of a bundle of filaments into the appropriate cavity it is conveniently surrounded by sheet material 13 which may be removed after the bundle is correctly positioned within the cavity.
- a plurality of springs 14 are housed in recesses 15 in the central region 5 of the core I. It requires the application of pressure to the springs 14 to force them to lie wholly within the recesses 15 and the necessary tensioning force for the springs is obtained by the casing 2 acting via the bundle of filaments 11.
- the dispenser would be borne aloft by any convenient means (e.g., by a carrier rocket) and when ejected, fuses for the destructible pegs would be fired. These fuses have variable time delays so that the destructible pegs are fired in sequence. This ensures that the parts of the casin g 2 are removed one alter the other, removal of each part of the casing opening one of the cavities 7, 8, 9 or 10 and allowing the various springs 14 associated with that cavity to eject the individual bundles of filaments. By suitably delaying the release of the four parts of the casing it is possible to ensure a wide distribution of the radar-reflective filaments.
- Payloads e.g., flares
- Other payloads e.g., flares
- An airborne dispenser comprising a cruciform core member having a plurality of primary recesses located in the surface of the core member between adjacent arms thereof, each of the recesses being divided into compartments for receiving material to be dispensed, each compartment having a secondary recess in the core member for receiving a spring member, a spring member in each secondary recess for expelling the material from the primary recess, a cover member including segments each covering a primary recess in the core member, and explosive means forcibly releasing each cover member, said explosive means being arranged to operate sequentially.
