ABSTRACT:
An aircraft sustentation system is disclosed which consists of one pair of fixed swept primary wings attached to the fuselage of the aircraft, and one pair of pivotal swept transverse wings attached to the fuselage of the aircraft in a manner where all leading edges, trailing edges, and lateral angles of both sets of wings are parallel or exceed a parallel relationship to each other, the pivotal transverse wings possessing transverse wing collars capable of accepting accessory and/or landing gear supports or wells; and the pivotal transverse wings utilizing actuation mechanisms capable of canting, laterally tilting, and variable sweeping the transverse wings in a manner where the swept transverse wing leading edges approach or contact the trailing edge of the primary wing or primary wing flap with a parallel relationship during the low-speed high-lift configuration.
