The flare ignition system is integrated in an ejector system (2), which additionally comprises an accelerator unit (3) surrounding the tube nozzle (1) and a heat insulation (4) bound between the two. ## Claims ### Claim 1 An ejection system comprising: (A) a flare ignition system comprising i. a tubular connecting stub provided with one or more heating elements disposed to heat the tubular connecting stub, wherein the tubular connecting stub has a conically tapering shape, wherein contactless ignition of an ejectable flare occurs due to heat transfer from the tubular connecting stub to a pyrotechnic film of the flare when the tubular connecting stub is heated by the one or more heating elements and when the flare is disposed along an inner wall of the tubular connecting stub, wherein the flare is polygonal in shape and comprises corners, wherein the number of corners is greater than three, and the flare is coated with the pyrotechnic film, wherein when ignited, the flare produces a pyrotechnic signature suitable for producing a camouflage screen for the protection of vehicles and objects; (B) an acceleration unit that is disposed adjacent to the tubular connecting stub of the flare ignition system; and (C) a heat decoupling that is located between the acceleration unit and the tubular connecting stub. ### Claim 2 (depends on 1) The ejection system as claimed in claim 1, wherein the tubular connecting stub has a rear internal diameter (DIR-1) and a front internal diameter (DIR-2), wherein a diagonal (DF) between corners of the flare is greater than the front internal diameter (DIR-2) but is less than or equal to the rear internal diameter (DIR-1) of the tubular connecting stub. ### Claim 3 (depends on 2) The ejection system as claimed in claim 2, wherein the flare is accelerated by the acceleration unit either mechanically, or pneumatically, or pyrotechnically. ### Claim 4 (depends on 3) The ejection system as claimed in claim 3, wherein the acceleration unit comprises a spindle drive, and the flare is mechanically accelerated by the spindle drive of the acceleration unit. ### Claim 5 (depends on 3) The ejection system as claimed in claim 3, wherein the acceleration unit comprises a pneumatic system, and the flare is pneumatically accelerated by the pneumatic system of the acceleration unit. ### Claim 6 (depends on 1) The ejection system as claimed in claim 1, wherein the flare is accelerated by the acceleration unit either mechanically, or pneumatically, or pyrotechnically. ### Claim 7 (depends on 6) The ejection system as claimed in claim 6, wherein the acceleration unit comprises a spindle drive, and the flare is mechanically accelerated by the spindle drive of the acceleration unit. ### Claim 8 (depends on 6) The ejection system as claimed in claim 6, wherein the acceleration unit comprises a pneumatic system, and the flare is pneumatically accelerated by the pneumatic system of the acceleration unit. ### Claim 9 (depends on 1) The ejection system as claimed in claim 1, wherein the heat decoupling comprises insulation. ### Claim 10 An ejection system comprising: (A) a flare ignition system constructed to eject an ejectable flare that produces a pyrotechnic signature with the aim of producing a camouflage screen for the protection of vehicles and objects, wherein the flare is polygonal in shape and comprises corners, wherein the number of corners is greater than three, and the flare is coated with a pyrotechnic film, and wherein the flare ignition system comprises i. a tubular connecting stub provided with one or more heating elements disposed to heat the tubular connecting stub, wherein the tubular connecting stub has a conically tapering shape, wherein contactless ignition of the flare occurs due to heat transfer from the tubular connecting stub to the pyrotechnic film of the flare when the tubular connecting stub is heated by the one or more heating elements and when the flare is disposed along an inner wall of the tubular connecting stub, and wherein the one or more heating elements are selected from the group consisting of electrical heating elements and a burner; (B) an acceleration unit that is disposed adjacent to the tubular connecting stub of the flare ignition system; and (C) a heat decoupling that is located between the acceleration unit and the tubular connecting stub. ### Claim 11 (depends on 10) The ejection system as claimed in claim 10, wherein the tubular connecting stub has a rear internal diameter (DIR-1) and a front internal diameter (DIR-2), wherein a diagonal (DF) between corners of the flare is greater than the front internal diameter (DIR-2) but is less than or equal to the rear internal diameter (DIR-1) of the tubular connecting stub. ### Claim 12 (depends on 11) The ejection system as claimed in claim 11, wherein the flare is accelerated by the acceleration unit either mechanically, or pneumatically, or pyrotechnically. ### Claim 13 (depends on 12) The ejection system as claimed in claim 12, wherein the acceleration unit comprises a spindle drive, and the flare is mechanically accelerated by the spindle drive of the acceleration unit. ### Claim 14 (depends on 12) The ejection system as claimed in claim 12, wherein the acceleration unit comprises a pneumatic system, and the flare is pneumatically accelerated by the pneumatic system of the acceleration unit. ### Claim 15 (depends on 10) The ejection system as claimed in claim 10, wherein the flare is accelerated by the acceleration unit either mechanically, or pneumatically, or pyrotechnically. ### Claim 16 (depends on 15) The ejection system as claimed in claim 15, wherein the acceleration unit comprises a spindle drive, and the flare is mechanically accelerated by the spindle drive of the acceleration unit. ### Claim 17 (depends on 15) The ejection system as claimed in claim 15, wherein the acceleration unit comprises a pneumatic system, and the flare is pneumatically accelerated by the pneumatic system of the acceleration unit. ### Claim 18 (depends on 10) The ejection system as claimed in claim 10, wherein the heat decoupling comprises insulation. ### Claim 19 An ejection system comprising: (A) at least one ejectable flare, wherein the flare is polygonal in shape and includes corners, wherein the number of corners is greater than three, and the flare is coated with a pyrotechnic film;
