An aircraft static discharger is a device installed on aircraft to help prevent damage and potential shock hazards caused by static electricity buildup. Static electricity can be generated by friction between two surfaces, such as the wings and fuselage of an aircraft.
The static electricity builds up in the form of a static charge, and if not properly dissipated, it can cause sparking, arcing, and even fires. Aircraft static dischargers help to reduce static electricity buildup by providing an ionized path for it to be safely dissipated.
Static electricity is generated by friction between two surfaces, such as the wings and fuselage of an aircraft. This friction produces a charge which builds up over time, leading to a static charge.
If not dissipated properly, this static charge can lead to arcing, sparking, and even fires. Aircraft static dischargers help to reduce this static charge by providing an ionized path for it to be safely dissipated.
Aircraft static dischargers, also known as static wicks, are typically installed on the wing tips and tail of an aircraft. They consist of a woven copper wire surrounded by a conductive material, with the wire being connected to the aircraft’s frame.
As the aircraft moves through the air, the static wick is exposed to the airflow and the static charge is dissipated through the conductive material, allowing the aircraft to remain safe from static electricity buildup.
Aircraft static dischargers are designed to reduce the static charge on an aircraft. The device works by providing an ionized path for the static charge to be safely dissipated. The static dischargers are typically installed on the wing tips and tail of an aircraft, and consist of a woven copper wire surrounded by a conductive material.
As the aircraft moves through the air, the static charge is dissipated through the static wick, reducing the potential for sparks, arcing, and fires.
The Global Aircraft Static Dischargers market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A lightning survivable discharger (Null-Strike PN 16785) designed by Dayton-Granger, Inc. guards and reduces lightning damage to the aircraft trailing edge structure. A high-performance Null-Strike trailing edge static discharger with a maximum speed of 600 knots, the 16785 is intended for use in business and commercial aircraft. It is made up of a dispersed resistive element put into a metal shank.
The resistive element is outfitted with a unique thermo-fit shrink tube to shield it from rain erosion and features a semi-conductive carbon discharge point for optimal noise reduction.
It is stable from -65°C to +125°C, lightweight, and aerodynamically built to minimize drag. It has a DGspecial “STRIKEGUARD” lightning diverter element that reduces lightning damage to the aircraft’s trailing edge by deflecting lightning hits.
Particles of finely deposited aluminum oxide that have been epoxied to the discharger body’s exterior make up the Strikeguard diverter element. Its electrical properties allow it to be represented as a short circuit at voltage levels encountered during a lightning strike and as an open circuit at DC potentials.
Lightning that strikes the discharger will follow the ionized route made by the aluminum oxide particles and end up on the metal shank. The likelihood of lightning harming the aircraft’s trailing edge is decreased by this conduction.
