Description
антенны радиолокатора (на чертеже не показан ) выполнены окна 6 и 7. Между щелевыми антеннами и окнами наход тс перемычки 8. Между накладками 2 имеютс искровые промежутки 9, которые образуютс , например, вкладышами 10 в Л -образных ребрах 3. Искровые промежутки изолируют накладки одна от другой, но не преп тствуют прохождению токов молнии. При такой конструкции обтекател наиболее веро тны удары молнии в ребра 3 накладок 2, а удары в перемычки менее веро тны и не опасны, так как щели 5 антенн в этом случае не повреждаютс , а ток молнии через корпус 1 внутрь обтекател не проходит и не разрушает его. Ожоги и даже прожоги отверстий в накладках не вывод т из стро и практически не ухудшают работу молниезащитного устройства и антенн . Веро тность же удара молнии через диэлектрик корпуса 1 мимо токопровод щих накладок 2 в удаленные металлические части самолета близка к нулю.The radar antennas (not shown) have windows 6 and 7. There are jumpers 8 between the slot antennas and the windows. There are spark gaps 9 between the lining 2, which are formed, for example, by inserts 10 in L-shaped ribs 3. The spark gaps isolate the lining one from the other, but do not prevent the passage of lightning currents. With this design, the lightning strikes are most likely to strike lightning in the ribs of the 3 pads 2, and the jumps to the jumpers are less likely and not dangerous, since the slots of the 5 antennas in this case are not damaged, and the lightning current through the housing 1 does not penetrate him. Burns and even burn-through holes in the plates are not worn out and practically do not impair the operation of the lightning protection device and antennas. The probability of a lightning strike through a dielectric of body 1 past conductive plates 2 to remote metal parts of the aircraft is close to zero.
В случае необходимости размещени в обтекателе антенн нескольких диапазонов в качестве таких щелевых антенн могут использоватьс и другие вырезы, например окна 6 и 7.If it is necessary to place multiple ranges in the antenna radome, other notches can be used as such slot antennas, for example windows 6 and 7.
При обеспечении требуемой радиопрозрачностн обтекател его молниезащищенность близка к 100%, при этом встроенные в обтекатель антенны, используемые дл совместной работы с аппаратурой посадки, обеспечивают необходимые параметры.Providing the required radiotransference of the fairing, its lightning protection is close to 100%, while the antennas built into the fairing, used for collaboration with the landing equipment, provide the necessary parameters.
