Application filed April 24, 1925. Serial No, 25,497.

To all whom it may concern:

Be it known that L Wanrnn Bonsorm, a citizen of Germany, residing at Plymouth,

in the county of Luzerne and State of Penn than air and lighter than air machines and proposes to use an enclosed bag and a plurality of sustaining planes at various pos1- tions'on the structure to give the same a1r buoyancy. Y

The above and other objects will become apparent inthe description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a top plan view of the air craft.

Figure 2 is a side elevational view of the.

same. v

Figure 3 is a. cross sectional elevational view taken on line 33 of Figure 2.

Referring in detail to the drawing, the numeral indicates the fuselage. Th s fuselage is longitudinal in outline and 1s stream-lined thruout its length having a curved nose fore and aft, and its bottom s substantially semi-circular to decrease air resistance of the fuselage to the mimmum. The fuselage has planes 13 and 14: extending transversely therefrom at positions intermediate its length, and these planes are retained in their position by spars 15 which extend upwardly and are mounted on the underside of a flat sustaining surface 16 of the bag. This bag is of the same length as the fuselage and has a semi-circular 1nverted roof 17 whose ends are connected to the fiat surface 16 to form'a hermetically sealed compartment 18. It is well known that a plane surface in being projected horizontally thru the air and slightly tilted has an oval vacuum pocket formed above the plane surface. This vacuum pocket is of the same shape and volume as the curved roof 17 of the bag, and therefore this vacuum volume is utilized to aid in lifting the air craft. It is to be noted that the bag used in this construction is rigid and nonyieldable. The roof of the bag is formed in an inverted semi-circular outline to decrease the air resistance of the same to the m1n1- mum, as is the case with the fuselage, and

PATENT oFFI-Caw at its forward and rear ends, is provided with a rounded nose. the airship, a plurality of platforms are anchored. These platforms '19 are shown three in number, but may be of any desired number to suit the needs of control capacity of the air craft to which they are attached. The platforms are superposed one over the other, and between them, have vertical steering blades 20 which are fitted on posts 21 the latter being adapted to be rotated in order to move the blades 12. To each of the platforms 19, an elevator aeleron' 22 is hingedly attached, the hinges forming part of and projecting from the forward'edge of the aeleron and cooperate withhinge pins anchored in the rear ends of the platforms 18 These aeler-ons are also superposed one over the other and move m unison by being connected together by pairs of parallel spars 23. The planes 13 and 14 are of hollow construction and house the driving means for propelling shafts 24 which extend from the forward or entering edges of the planes and have propellers 25 mounted at their forward ends. These propeller shafts diverge forwardly toward the outside edge of the planes in which they are anchored so that a side wise and forward thrust is obtained, resulting in increased propelling power. The motive power which is adapted to drive these propeller shafts is housed withinthe fuselage and is connected to the propeller shafts by gearing and other shafts, as is most convenient. The entire airship is supported on wheels, skids, or any other means required to fit the local conditions of the place at whichthe airship is used. The wheels 26,

shown in several views of the drawing, are

of the pneumatic type and are rotatably mounted on a shaft 27 which is su ported in the bearings of undercarriage f and 29, these frames being secured to the floor of the fuselage at convenient spacedapart positions. The compartment 30 of the fuselage may be so constructed to serve for At the rear ends of rames 28 a passengers or freight, or for military use, 1

and is entered thru a door 31 which may be located conveniently at the center of the This vacuum pocket would be of an.

and the roof 17 of the bag, and the bag is therefore constructed with these dimensions in view. The bag is provided with an in-' verted semi-circular roof to give the least amount of surface"fri'ctioirand resistance to forward travel and its lower surface is formed flat to provide a sustaining bladefor the entire airship, Ascentand descent is controlled by the elevator"a'elerons22 and the rudder bladesvmaneuver the ship horizontally. Forward travel of the entire ship may be obtained by rotation of the 'propeh lei" blades which are actuated from the power situated within the fuselage chamber bag comprising an inverted semi-circular} roof, the bottom of sa d bag being formed into a flat sustaining surface, a fuselage suspended beneath the flat surface of said bag,

a plurality of horizontal rudders superimposed one above the other and parallel to each other, and vertical rudders between said rudders for steering the ship horizontally, the rudders being movable to steer the ship angularly.

.JfAn airship comprising a stream-lined rigid bag having an inverted semi-Oval roof, the bottom of saidba'g. being formed into a flat plane sustaining surface, a fuselage suspended beneath the flat 'surfaceo'f said bag and extendingit's' entirelength, a plurality of horizontal rudders superimposed one above the other and parallel toeach other, and planes extending outwardly from the fuselage and being suspended from the flat surface of the bag intermediate their length, propeller shaftsfmounted in the planes and projecting forwardly and angular-1 y from the entering edges of said planes in opposite directions, and propellers on the "shafts of said planes when rotated being adapted to:

create a forward and externally sidewise thrust of said airship.

In testimony whereof I afiix my signature.
