Aircraft design and technology

An aircraft designed to provide sustained G forces, with a relatively high steady angle of attack maneuverability using less thrust by balancing thrust and drag to sustain a high turn rate with dual low thrust engines using novel wing and fuselage designs. The aircraft includes a wing oriented laterally relative to the fuselage, at least one horizontal tail surface extending laterally from the fuselage and positioned rearward of the fixed wing, and at least one vertical tail surface extending upward from the fuselage. The first and second engines are mounted to the fuselage at locations positioned vertically below the fixed wing. The aircraft includes leading edge root extensions mounted to the fixed wing and the fuselage at a leading edge of the fixed wing, at least one dynamic slat mounted to a leading edge of the wing structure, and a chine formed in the fuselage along lateral sides thereof at a nose of the aircraft.
