Abstract
An infra-red emitting decoy flare capable of diverting an incoming missile equipped with a counter-countermeasures system away from an intended target consisting of a primer flare (2), a spectral flare (4) and a means for igniting the primer flare (22, 30), all contained within a flare casing (6). The primer flare (2) is formed from a fast burning pyrotechnic composition and is adapted to produce an intense infra-red source of short duration on ignition. The spectral flare (4) is ignited by the burning of the primer flare (2) and is adapted to produce a slower burning composition having a fixed ratio in the intensity of infra-red radiation emitted, when burning, in at least two fixed bands.
Claims
1. An infra-red emitting decoy flare comprising a flare casing (6), two pyrotechnic components housed within the flare casing and an ignition means (30) for igniting the pyrotechnic components characterised in that the two pyrotechnic components comprise a primer flare (2; 50) and a spectral flare (4) wherein the primer flare (2; 50) consists of at least one primer pellet (8; 42; 52), each primer pellet being composed of a fast burning pyrotechnic composition and being adapted such that, in use, ignition of one primer pellet causes rapid ignition of all the primer pellets to produce an intense infra-red source, wherein the spectral flare (4) consists of at least one spectral pellet (10), each spectral pellet being of a pyrotechnic composition adapted such that, in use, ignition of the spectral pellets produces a spectral infra-red source wherein the ratio of the intensity of the infra-red spectrum at at least two fixed bands is within a fixed range, and wherein the primer flare (2; 50) and spectral flare (4) are adapted such that, in use, the spectral flare (4) is still burning after the primer flare (2; 50) has finished burning.
2. An infra-red emitting decoy flare as claimed in claim 1 wherein the spectral flare (4) is adapted such that the intensity of the infra-red radiation emitted, in use, is greater than that normally emitted from an intended target.
3. An infra-red emitting decoy flare as claimed in claim 1 or claim 2 wherein the primer flare (2) comprises a stack of discs (8) of a pyrotechnic composition.
4. An infra-red emitting decoy flare as claimed in any preceding claim wherein the primer flare (2) is provided with a central hole (12). -14-
5. An infra-red emitting decoy flare as claimed in any of the preceding claims wherein the primer flare (2) is provided with a plurality of holes (44).
6. An infra-red emitting decoy flare as claimed in any of claims 1 to 4 wherein the primer flare (50) has a plurality of grooves (54) in its surface.
7. An infra-red emitting decoy flare as claimed in any preceding claim wherein the bum time of the primer flare (2; 50) is within the range of 100 to 600ms.
8. An infra-red emitting decoy flare as claimed in claim 7 wherein the bum time of the primer flare (2; 50) is in the range of 150 to 250ms.
9. An infra-red emitting decoy flare as claimed in any preceding claim wherein the spectral flare (4) comprises a single pellet (10).
10. An infra-red emitting decoy flare as claimed in claim 9 wherein the spectral flare (4) is provided with a central hole (14).
11. An infra-red emitting decoy flare as claimed in any preceding claim wherein the spectral flare (4) and primer flare (2; 50) are adapted such that, in use, the spectral flare is ignited by the burning of the primer flare
12. An infra-red emitting decoy flare as claimed in any preceding claim wherein the primer flare (2; 50) is formed from a fast burning magnesium-Teflon-Niton composition.
13. An infra-red emitting decoy flare as claimed in any of claims 1 - 11 wherein the primer flare (2; 50) is formed from a pyrotechnic composition adapted such that, in use, ignition of the primer pellet produces an intense spectral infra-red source wherein the -15- ratio of the intensity of the infra-red spectrum at at least two fixed bands is within a fixed range.
14. An infra-red emitting decoy flare as claimed in claim 13 wherein the primer flare (2; 50) is comprised from a composition of potassium benzoate, potassium perchlorate and a binder chosen from the group of RDX, HMX or HNS.
15. An infra-red emitting decoy flare as claimed in any preceding claim wherein the spectral flare (4) is formed from a pyrotechnic composition which produces quantities of gas on ignition.
16. An infra-red emitting decoy flare as claimed in any preceding claim wherein the spectral flare (4) is formed from a composition having an organic fuel, an oxidant and a binder.
17. An infra-red emitting decoy flare as claimed in claim 16 wherein the organic fuel is chosen from the group comprising sucrose, lactose, starch and potassium benzoate.

20. An infra-red emitting decoy flare as claimed in any of claims 16 - 19 wherein the binder is chosen from the group of Niton A, dextrin or polybutyl rubber. -16-
21. An infra-red emitting decoy flare as claimed in any of claims 16 - 19 wherein the binder is an explosive material having a waxy composition.
22. An infra-red emitting decoy flare as claimed in claim 21 wherein the binder is chosen from the group of RDX, HMX and HNS.
23. An infra-red emitting decoy flare as claimed in claim 1 wherein the spectral flare composition (4) is formed from a mix of 30-40% by mass of potassium benzoate and 60-70% by mass of potassium perchlorate together with 3-8% by mass of Niton A, RDX, HMX or HΝS.
24. An infra-red emitting decoy flare as claimed in claim 1 wherein the spectral flare composition (4) is formed from a mix of 30% by mass of boron and 70% by mass of potassium nitrate together with a Niton A binder.
25. An infra-red emitting decoy flare as claimed in any of claim 18 wherein the spectral flare composition (4) comprises an additive such as silicon.
26. An infra-red emitting decoy flare as claimed in claim 25 wherein the spectral flare composition (4) is formed from a mix of 20% by mass of boron, 10% by mass of silicon and 70% by mass of potassium nitrate together with a Niton A binder.
