An apparatus and method are provided for reducing the drag of an aircraft wing. Many modern high speed aircraft have a low aspect ratio wing generating significant induced drag. The invention provides a drag reduction system, which is made up of a high aspect ratio supplementary wing connected to the fuselage by a streamlined fuselage connection, and at least two struts connecting the supplementary wing to the main wing. The drag reduction system is capable of reducing the total drag of a modern high speed, high altitude aircraft with a low aspect ratio ...

1. An aircraft comprising: a body; a supplementary wing comprising two wing, sections extending outwardly on either side of the body, to provide lift for the body; and a wing support structure for the supplementary wing extending between the body and the supplementary wing, wherein the supplementary wing is configured to reduce induced drag and the supplementary wing by itself has insufficient strength to support the aircraft, wherein the wing support structure comprises a main wing and provides additional strength to withstand loads applied to the suppl...
