The invention belongs to the technical field of aircraft electrostatic protection, and relates to a stealth aircraft electrostatic discharge device. The device comprises a plurality of discharger bodies (5) which are installed in installation grooves in the rear edges of wings and the two sides of a rear fuselage of a stealth aircraft and are conformal with the wings and the rear fuselage of the stealth aircraft, metal needles (6) which are fixed on the discharger bodies (5) and are provided with needle tips protruding out of the body of the stealth aircraft, and protection columns (7) which are located on the two sides of the metal needles (6) and coated with a stealth material so as to protect the metal needles. According to the invention, the problem of stealth aircraft deposition electrostatic discharge is solved, the radar scattering area of the aircraft electrostatic discharge device is greatly reduced, the radio frequency stealth of the electrostatic discharge device of the aircraft body structure protruding part of the stealth aircraft meets the design requirement of the stealth aircraft, the design of the independent discharge needles is adopted, the single discharge spectrum width is effectively controlled, and the electrostatic noise interference is reduced.
本申请属于飞机静电防护技术领域,涉及一种隐身飞机静电放电装置。所述装置包括多个放电器主体(5),安装于隐身飞机的机翼后缘及后机身两侧的安装槽内,并与所述隐身飞机机翼及后机身共型;金属针(6),固定在所述放电器主体(5)上,并具有突出隐身飞机的机体之外的针尖;保护柱(7),位于所述金属针(6)的两侧,其上涂覆有隐身材料,以对金属针进行保护。本申请解决了隐身飞机沉积静电放电问题,大大降低了飞机静电放电装置的雷达散射面积,解决了隐身飞机突出飞机机体结构部分静电放电装置的射频隐身满足隐身飞机设计需求,采取了单独放电针的设计,有效控制了单次放电频谱宽度,降低了静电噪声干扰。
