ABSTRACT:
An airplane is disclosed which has a pair of fixed, outwardly extending delta wings extending laterally from a fuselage, a set of initial flaps pivotably attached to the rear of the fixed wings, a set of dependent flaps pivotably attached to the rear of the initial flaps, and a variable positionable concomitant stablizer located at the rear of the dependent flaps forming the rear of the delta wings during the high-speed configuration capable of achieving independence from the fixed wings upon actuation of the flap system; the above components all locked together to form the delta wing during high-speed flight with an actuator which also serves as a stress supporter for the flap system during its actuation.
