Abstract

It is inevitable for civil aircraft to encounter lightning during flight. The vent of fuel tank is the inlet and outlet for the exchange of gas in the fuel tank with the outside atmosphere. Corona and streamering may be generated at the vent cap when encountering lightning. The vent cover shall be designed reasonably to prevent the corona streamering from igniting fuel vapor in the fuel tank. This paper analyzes the airworthiness requirements of lightning protection of fuel tank vent cap, describes the structural design characteristics of typical vent cover and its layout on the wing, and discusses the corona streamering certification test of fuel tank vent cap, so as to provide reference for airworthiness certification of lightning protection design of fuel tank vent cap.
