Title:
AIRCRAFT DRAINMAST ASSEMBLY WITH LIGHTNING PROTECTION
Document Type and Number:
WIPO Patent Application WO2002036426
Kind Code:
A3
Abstract:
An aircraft drainmast assembly (10) including a drainmast (20) for ejection of waste water from an aircraft (12) and a grounding plate (24) for protection against lightning strike currents. The grounding plate is made of an electrically conductive material and is attached to the metallic drain tube (32) in such manner (e.g., welding) that a conductive path is established between the grounding plate and the drain tube. The grounding plate is placed in contact with the aircraft fuselage during installation of the drainmast whereby an electrically conductive path is formed thereby allowing lightning strike currents to travel from the drain tube to the grounding plate to the aircraft fuselage. The grounding plate may be pressed against the outside surface of the fuselage by an elastomeric gasket (22) installed between the grounding plate and a flange of the drainmast's fairing thereby allowing for a simple lightning protection installation from the outside of the aircraft.
