Lightning protection device for an aircraft, aircraft comprising such a lightning protection device

A lightning protection device for an aircraft, comprising:

• an anti-corona element having a rounded shape and having an electrically conductive surface, configured for enveloping an area of an airframe of the aircraft that is liable to receive a lightning strike;
• at least one electric charge dissipator attached to said anti-corona element;
• a second electric charge dissipator;
• and
• a dielectric shell surrounding the anti-corona element and the at least one and the second electric charge dissipators, each of the at least one and the second electric charge dissipators passing at least partially through said dielectric shell,
• wherein each of the at least one and the second electric charge dissipators comprises an electrically conductive rod, a first end of the electrically conductive rod attached to the anti-corona element and a second end of the electrically conductive rod serving as an attachment point for a set of electrically conductive filaments, of which only one end of each of the set of electrically conductive filaments, distal from the rod, protrudes from the dielectric shell,
• wherein the anti-corona element is substantially spherical, the dielectric shell is substantially ellipsoidal in shape, the center of the dielectric shell substantially coinciding with the center of the anti-corona element, and
• wherein each of the at least one and the second electric charge dissipators extends radially from the anti-corona element at two points that are diametrically opposed along the longest axis of the ellipsoid formed by the dielectric shell.
