17 results about "Static discharger" patented technology

Static dischargers, commonly known as static wicks or static discharge wicks, are installed on the trailing edges of aircraft, including (electrically grounded) ailerons, elevators, rudder, wing, horizontal and vertical stabilizer tips. Fitted on almost all civilian aircraft today, they are high electrical resistance (6-200 megaohm) devices with a lower corona voltage than the surrounding aircraft structure. They control the corona discharge into the atmosphere. They are used on aircraft to allow the continuous satisfactory operation of onboard navigation and radio communication systems during precipitation (p-static) conditions. Precipitation static is an electrical charge on an airplane caused by flying through rain, snow, ice, or dust particles. When the aircraft charge is great enough, it discharges into the surrounding air. Without static dischargers, the charge discharges in large batches through pointed aircraft extremities, such as antennas, wing tips, vertical and horizontal stabilizers, and other protrusions. The discharge creates a broad-band radio frequency noise from DC to 1000 MHz, which can affect aircraft communication. Static dischargers contain sharper points than any other part of the aircraft, cause the charge to discharge through them instead, and do so gradually.

Integrated trailing edge structure and winglet assembly with electrostatic discharger installed.

This utility model relates to the field of aircraft structural design technology, and discloses an integral trailing edge structure and winglet assembly for mounting an electrostatic discharger. The integral trailing edge structure for mounting the electrostatic discharger includes a trailing edge strip and a bushing. A mounting hole is provided on the edge of the trailing edge strip, located at the center of the strip's thickness direction. The bushing is interference-fitted into the mounting hole, and its inner wall has an internal thread. The mounting end of the electrostatic discharger has an external thread that matches the internal thread, allowing it to be threadedly connected to the bushing. Providing a mounting hole on the edge of the trailing edge strip, compared to the conventional method of fixing the electrostatic discharger to the winglet trailing edge using a mounting base, avoids a large area of ​​the electrostatic discharger protruding from the aerodynamic shape after mounting, thus reducing flight drag and aerodynamic wear. The electrostatic discharger and trailing edge strip are threadedly connected by the bushing. The bushing's interference fit with the mounting hole allows for easy and economical maintenance by replacing the bushing when its internal thread wears.
