Description

[Technical field]

[0001] The present invention relates to an active element, in particular a decoy active element, which comprises at least one active element and at least two ignition means, each comprising a pyrotechnic composition for igniting the active element.

[0002] Additionally, the present invention relates to a method for igniting an active element. [Background technology]

[0003] Active elements such as decoy active elements are used in aviation. Since about 1970, such decoy active elements have been placed under a protective film or in a container and ignited from one side. This is especially true for all conventional MTV (Magnesium-Teflon-Viton) decoy active elements and for spectral decoy active elements.

[0004] The ignition chain is activated from the ignition side, preferably via a fail-safe system, to the active element, which in the case of an aircraft is preferably elongated, and then ignites the active element after release. These active elements often have a fast-burning coating composition to achieve ignition from all sides within the required time.

[0005] Decoy active elements having certain active elements and geometries may have ignition issues due to the type of design and use, which may lead to delayed and reduced power delivery during the early stages of ignition.

[0006] Typically, ignition is initiated from the ignition side in the base region, which is the so-called end face of the active element, and eventually spreads inside or outside the element along the surface in the direction of the ejection side to achieve reaction of the active element on all sides.

[0007] The ignition issues outlined above can have a direct impact on effectiveness with regard to hazards during the ignition phase.

[0008] Document DE 10 2009 030 871 A1 discloses an active element which comprises a container for a combustible active substance made of a plastic film, which can be inductively ignited by a laser or by high temperature.

[0009] DE 10 2016 122 740 A1 discloses a pyrotechnic active element having a housing, an ignition device and at least one active composition. The ignition device is arranged, for example, at the bottom of the active element.

[0010] Patent application DE 10 2010 030 869 A1 discloses active elements comprising a number of active substances, which have a number of individual flares arranged one behind the other and which can be inductively ignited by a laser or by high temperature.

[0011] DE 10 2009 030 872 A1 relates to an inductively ignited active element, which consists of individual flares packed into a carrier material such as steel foil coated with red phosphorus.

[0012] An encapsulated active element having a number of individual components for an infrared decoy and providing central longitudinal ignition is known from DE 10 2010 013 110 A1.

[0013] DE 10 2004 047 231 A1 discloses a generic active element having a number of active elements and ignition means, but does not disclose how ignition is effected or how the ignition means are arranged.

[0014] Depending on the geometry of the base and active elements, there may be no suitable approved or reliable coating composition available for implementation as a military active element. Changing the composition or geometry of the active element is not possible without limitations imposed by existing systems, and therefore, target impingement exists in this case.

[0015] Furthermore, without a coating composition, ignition from all or multiple sides cannot be guaranteed. [Prior art documents] [Patent documents]

[0016] [Patent Document 1] DE 10 2009 030 871 A1 [Patent Document 2] DE 10 2016 122 740 A1 [Patent Document 3] DE 10 2010 030 869 A1 [Patent Document 4] DE 10 2009 030 872 A1 [Patent Document 5] DE 10 2010 013 110 A1 [Patent Document 6] DE 10 2004 047 231 A1 Summary of the Invention [Problem to be solved by the invention]

[0017] Hence, the problem addressed by the present invention is to provide an active element that allows for rapid and reliable ignition of multiple active elements. [Means for solving the problem]

[0018] This problem is solved by an active element according to claim 1. Furthermore, the problem is solved by a method according to claim 13. Advantageous embodiments and developments are the subject matter of the respective dependent claims.

[0019] According to the invention, there is provided an active element, in particular a decoy active element, comprising at least one active material and at least two ignition means, each having a pyrotechnic composition for igniting the at least one active material, the at least two ignition means being arranged on the at least one active material and the at least two ignition means being connected to each other via channels so as to be able to ignite the at least one active material from multiple sides simultaneously.

[0020] The present invention further provides a method for igniting such an active element or an active element as described below. The active element comprises at least one active material and at least two ignition means, each comprising a pyrotechnic composition for igniting the active material. The at least two ignition means are disposed on the at least one active material, and the at least two ignition means are connected to each other via channels such that the at least one active material can be ignited from multiple sides simultaneously.

[0021] Therefore, according to the invention, it is proposed to design the active element in such a way that ignition can be initiated on multiple sides, but at least two sides, for example on the side and on the opposite side, thus an active element with multipoint ignition.

[0022] Preferably, the at least one active material is at least one pyrotechnic-type active material such as those used in flares.

[0023] The channels are preferably ignition channels designed to ignite or conduct ignition to the ignition means. The channels may be arranged symmetrically and / or asymmetrically with respect to each other.

[0024] "Simultaneously on multiple sides" means that the active element or at least one active material can be ignited at multiple points simultaneously, such as at the side, top, bottom or edge. Simultaneously within the meaning of the present invention means that at least one active material can be ignited with substantially no time delay.

[0025] Within the meaning of the present invention, ignition means are, for example, squibs, smaller ignition-sensitive pyrotechnic compositions or other known ignition means.

[0026] As a result of the multi-surface ignition according to the invention, less sensitive active material over a large area can be ignited quickly and reliably with a significantly smaller ignition means.

[0027] Since a plurality of ignition means are provided, the reliability of ignition is improved by providing the ignition means redundantly.

[0028] Moreover, such an active element would have a disruptive effect on all sides immediately after being launched (for example from an airplane), allowing it to reliably evade oncoming missiles.

[0029] Furthermore, due in particular to the fact that at least one active material can be ignited from multiple sides simultaneously, a reduced scattering behavior during use and an increased response are achieved by the active element according to the invention. Furthermore, the effectiveness of the active element is improved.

[0030] In an advantageous development of the invention, it can be provided that a plurality of active substances, preferably each of the active elements, can be ignited simultaneously from a plurality of sides.

[0031] The at least two active materials may be the same size and / or different sizes. By using multiple different active materials, the wavelengths in the spectrum emitted by the active element during combustion of the active materials can be tailored.

[0032] In an advantageous development, the active element has at least two active substances, and the ignition means are arranged between the active substances in the active element such that the at least two active substances can be ignited simultaneously from multiple sides.

[0033] This ensures that each active material of the active element is ignited reliably and simultaneously, and that the active element produces a good perturbation effect on all sides.

[0034] Furthermore, the ignition means may advantageously be arranged inside and / or outside the active element.

[0035] The pyrotechnic composition and the at least one active substance of the ignition means may further be separated from each other by an inert material.

[0036] As a result, a predetermined separation of the ignition means of at least one active substance from the pyrotechnic composition is achieved, which prevents the active substance and the pyrotechnic composition from chemically influencing each other during storage of the active element, which in turn prevents undesired ignition, which in turn means that a predetermined ignition energy is required to ignite the body.

[0037] According to one embodiment, the at least one active substance and / or the ignition means can also be separated from one another by a film, a housing or a gap. The individual active substances can preferably be separated from one another in this way.

[0038] Such physical separation can be achieved, for example, by a film or an enclosure made of paper, plastic material or metal.

[0039] It can further be provided that the active elements have grooves, slots and / or holes. The channels extend into the grooves, slots and / or holes. The individual active elements are preferably separated by these grooves and / or slots. However, it is also possible that the grooves, slots and / or holes extend into the interior of the active elements.

[0040] The provision of grooves, slots and / or holes ensures that the positioning of the channels is predetermined and that the channels do not extend beyond or only slightly protrude beyond the contour of the active element.

[0041] In a further development, it can be provided that the grooves and / or slots extend such that they intersect at a plurality of intersection points, the ignition means being formed at the intersection points.

[0042] Providing such an intersection means that a plurality of active substances, for example four or eight active substances, are provided at a distance from one another at the intersection, such that a plurality of active elements can be ignited at one point by the ignition means.

[0043] Furthermore, the grooves, slots and / or holes may be located on the interior and / or exterior of the active element.

[0044] Additionally, the active element can be protected from environmental influences by a film or housing, which allows the active element to reliably ignite even in the presence of high wind and / or launch velocities, for example when launched from a high speed flying device or aircraft.

[0045] Further, in accordance with the present invention, the active element may be free of a pyrotechnic coating composition that covers the entire active element. Such a coating composition is a fast-burning composition that coats the active element and allows ignition from all sides. This has the advantage that the active element can be approved even without a suitable approved coating composition.

[0046] The ignition means may be arranged in this manner and the length of the channel may be shaped to allow the ignition means to be ignited simultaneously.

[0047] The ignition means may also be connected to an ignition initiator via a channel.

[0048] Embodiments of the method also allow for multiple active materials of an active element to be ignited simultaneously from multiple sides.

[0049] In an advantageous development, the active element may be substantially cubic or have a substantially cubic active material. In this case, the active element may in particular be an active element for 2x1x8" or 1x1x8" NATO standard caliber ammunition.

[0050] However, the active element may also be a cylindrical active element, preferably having a diameter of 36 mm or 55 mm.

[0051] The active elements may also be spherical or triangular in shape.

[0052] Hereinafter, the present invention will be described based on an embodiment with reference to the drawings. [Brief description of the drawings]
