Description

Technical Field

[0001] The present invention belongs to the technical field of electrostatic discharge equipment, and in particular relates to an electrostatic discharge device with measurement and emission functions, and also relates to a method for monitoring electrostatic current signals using the device. Background Art

[0002] When an aircraft is in flight, particles in the air collide with the aircraft's skin, causing charge transfer. This causes the aircraft surface to acquire a charge of one polarity, while the particles acquire a charge of the opposite polarity. To ensure flight safety, electrostatic dischargers (EDDs) are installed on the trailing edge and tip of the aircraft structure. These ESDs generate corona discharge at a low voltage, dissipating the charge deposited on the aircraft surface with a small current. To ensure effective ESD discharge throughout the aircraft, a sufficient number of ESDs must be installed and strategically positioned. The SAE ARP 5672 standard specifies relevant parameters for the aircraft's electrostatic environment and a theoretical calculation method for the number of ESDs to be installed. However, the standard lacks detailed regulations for ESD placement. With the increasing variety of aircraft models, especially newer aircraft, determining the placement and evaluation of ESD placement is crucial for aircraft ESD protection design. However, existing ESDs struggle to monitor discharge current during flight, making it difficult to assess the appropriate number and placement of ESDs. Summary of the Invention
