Problems solved by technology

Stealth aircraft requires good low-scattering performance, while traditional electrostatic dischargers are installed protruding from the exterior of the aircraft, so that there are a large number of protrusions on the original shape of the aircraft, which has a large radar cross-sectional area (RCS), which will produce more Strong radar target scattering characteristics, destroying the stealth characteristics of the aircraft

Abstract

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.

Description

technical field [0001] The application belongs to the technical field of aircraft electrostatic protection, and in particular relates to an electrostatic discharge device for stealth aircraft. Background technique [0002] Continuous collisions between aircraft and space particles (snowflakes, raindrops, dust, ice crystals, sand grains, etc.) will cause the accumulation of a large amount of electrostatic charge on the surface of the aircraft. Usually, it is necessary to install electrostatic discharge devices to conduct research on aircraft electrostatic discharge systems. The main research contents include electrostatic discharge. Design of electrical appliances and placement of electrostatic dischargers. Electrostatic dischargers are usually installed on the trailing edges and tips of aircraft wings and empennages to release static charges gently so that electrical and electronic devices are protected from radio frequency interference from electrostatic discharges. The tr...
