Abstract

The invention provides a stretchable static electricity discharge device for an aircraft. The device comprises a storage cylinder, a static electricity discharge device pole and an actuator, wherein the storage cylinder is installed on an aircraft body, at least part of the static electricity discharge device is contained inside the storage cylinder and can move between the retracting position andthe stretching position, at the retracting position, at least part of the static electricity discharge device is retracted into the storage cylinder, and at the stretching position, the static electricity discharge device pole stretches out relative to the retracting position; the actuator drives the static electricity discharge device pole to move between the stretching position and the retracting position. The static electricity discharge device can stretch and retract as needed, and the phenomenon that the device is impacted accidentally and damaged when the device is in the ground parkingstate is avoided.

Description

technical field [0001] The invention relates to a retractable electrostatic discharge device for aircraft. Background technique [0002] When the aircraft is flying, the surface of the aircraft is rubbed against dust, ice crystals, rain and other particles, the charged exhaust gas of the engine, and the induced charge generated by the charged cloud layer on the aircraft will all cause the aircraft to be electrified. If the generated charge is not discharged in time, there will be a large potential difference between the aircraft and the surrounding atmosphere, forming a corona discharge channel. The broadband electromagnetic field generated during this period is one of the main sources of noise that interferes with the receiver. The electromagnetic field passes through the skin surface and openings of the aircraft, and may couple with the avionics equipment, thereby causing failure of communication, navigation, and computer control, and even serious damage or accident of the...
