ABSTRACT:
A tandem wing aircraft is provided having two independent spaced apart fuselages and two wings of similar area, a lower forward wing and a higher aft wing. The lower forward wing is attached to the forward region of each of the spaced apart fuselages; the higher aft wing is aerodynamically spaced apart from and located above the aft region of the spaced apart fuselages. An aft strut member is disposed between the aft wing and each of the fuselages; each aft strut member has a length sufficient to cause the wing tips of the lower forward wing and the upper aft wing to be vertically spaced apart by a distance of at least 25% of the span of either of the wings.
