  • Patent number: 4913380
    Abstract: A high wing Canard aircraft mounts three strake fuel tanks within the top of the aircraft fuselage on the right and left sides thereof in a fore and aft array interconnected by horizontal interconnect lines at the bottoms of the strake tanks to provide an alternate fuel path in the event of tank-line contamination blockage and forming a secondary gravity feed system. A pair of wing tanks integrated to the high wing of the Canard aircraft, to the rear of the strake tanks, feed along with individual horizontal fuel lines from the strake tanks to a central fuel collector tank interposed between the main high wing sections with low pressure drop flapper check valves at the ends of the individual horizontal lines internally of the collector tank for preventing fuel from leaving the collector tank. The primary gravity feed system defined thereby isolates each tank from the other, thereby preventing large fuel excursions during extreme flight maneuvers.
