Patent ID: 8128029

Claim:
A ventral fairing for an aircraft locatable between a left wing with a left lower surface and a right wing of the aircraft with a right lower surface, the ventral fairing comprising: a lower central section of convex transverse cross-section locatable between said left lower surface and said right lower surface; an angle of less than 90 degrees between the cross-section of the fairing and the line of cross-section corresponding to the lower surface of each wing; a left lateral section of concave transverse cross-section which is extended between at least part of said left lower surface and said central section, and a right lateral section of concave transverse cross-section which is extended between at least part of said right lower surface and said central section; separate first lines of inflection between the lower surface of each wing and the corresponding lateral section; separate second lines of inflection between the lateral sections and the central section; a forward part in which are arranged said left and right lateral sections and the first lines of inflection; a rear part of convex transverse cross-section which does not include said left and right lateral sections nor the first lines of inflection; and separate transition sections in which the configuration of the transverse cross-section of the forward part is progressively adapted to the configuration of the transverse cross-section of the rear part.
