Abstract

121,990. Jackson, J. G. Dec. 7, 1917. Aerial machines without aerostats; planes, construction and arrangement of.-In aeroplanes of the kind provided with dihedral main planes and a tail portion comprising dihedral planes with a vertical fin underneath, the arrangement being such that the laterally projected areas of the dihedral surfaces equals the area of the fin, the dihedral and vertical tail-planes are made of increasing width from front to rear, and the main planes are arranged at an angle of incidence slightly greater than that of the tail-planes. Figs. 4 and 5 show the application to a hydro-aeroplane. The fuselage 23 is fitted with dihedral main planes 33 and tail-planes 28, 29 and with a fin 27. One or more additional main planes 34 may be provided. The invention is shown also applied to a flying-boat and to a land machine.
