This invention relates to a tandem or multi-winged aircraft wherein a primary wing system is so designed and equipped that it is capable of being actuated in a manner to bring about a shift in the neutral point of the craft relative to its center of gravity and wherein a secondary wing system located ahead of the primary one and movable fore and aft relative to the latter is deployed and angled during its excursion so as to effectively counteract the neutral point shift that would be brought about by deploying the primary wing system alone thereby mainta...


A tandem or multi-winged aircraft comprising: a fuselage; primary and secondary wing systems attached to said fuselage for supplying positive lift thereto; propulsion means for generating a forward thrust, said fuselage, wing systems and propulsion means cooperating to define a center of gravity and a neutral point having a spaced relationship to one another effective to maintain stable flight, said secondary wing system having an average positive lift per unit area greater than the average positive lift per unit area of said primary wing system, said se...
