A cruciform wing structure for a solar powered aircraft is disclosed. Solar cells 28 are mounted on horizontal wing surfaces 20, 22. Wing surfaces 24, 26 with spanwise axis perpendicular to surfaces 20, 22 maintain these surfaces normal to the sun\s rays by allowing aircraft to be flown in a controlled pattern at a large bank angle. The solar airplane may be of conventional design with respect to fuselage, propeller and tail, or may be constructed around a core 70 and driven by propeller mechanisms 75, 76, 77, and 78 attached near the tips of the airfoil...
An aircraft comprising: airfoil means having surfaces normal to each other for sustaining free flight of the aircraft; solar cells carried by at least one of said airfoil means surfaces for powering the flight of the aircraft; control means for orienting said airfoil means normal to the path of the sun\s rays; and means for constantly maintaining said solar cells normal to the path of the sun\s rays during an uninterrupted flight from at least sunrise to sunset.
