RIGID AIRSHIP.
Application filed October 2, 1924, Serial No.
My invention relates to the hulls of rigid air-ships which are made up of longltudinal and cross members, particularly to the construction of the cross members which are called rings and generally have apolygonal shape. The sides of the polygon cons1st of girders, and such girders are braced'by 1nternal wire bracing. All this construction is situated in one plane and this plane is.
1 rectangular to the ships longitudinal axis. According to my invention .the strength and resistance of such cross member construction is im roved by adding structural members exten ing out of the rings plane, thereby developing the cross member to azspatial truss. With increased size and diameter" of the ship, and with increased gas pressure, this ring construction will be of great advantage. The possible occurrence of surplus pressure on one side of a cross member will be much better resisted and the danger of distortion will be lessened.
Furthermore, a ring construction embodying my invention ermits of loads to be distributed on the ower arts thereof, especially when the rings orm corridors e2;- tending at right angles from the longitudinal corridor usual with ri d airships. The provision of a number 0 [such cross corridors facilitates the supervision of the hull structure .and especially that of the walls of the gas cells during the flights, which is of hi hest importance.
For t e purpose of increasing the advantage with such cross corridors it may be useful to provide'not only the usual longitudinal corridor at the lowest part of the ship, but to add other longitudinal corridors at any place of the ships circumference,
40 which now will be easily accessible by means of the new cross corridors according to my invention. For'example, a longitudinal corridor at the ridge of the ship will permit supervision of the operated valves during flight, which is an advantage of greatest value.
Having described my invention in a general way, I now want to point out the details thereof referring to the annexed drawto ing showing examples embodying my invention.
Fig. 1 is a cross section through a rigid airship showing a ring member.
741,240, and in Germany October 1a, 1923.
Fig. 2 is a vertical section through the middle of Fig. 1 looking to the left.
. Figs. 3 and 4 correspond to Figs. 1 and 2 respectively .but show another example of ring construction according to my iners b. The corners of the rings are numbered 1 to 12. Girders 0 are provided connectingoppos'itel-y situated ring corners, for examplejcorner 1 to corner 6, 12 to 7, 3 to 10 and i'to 9. These 'rders care not situated in the plane of this ring. but they project out of that plane and are provided in pairs, creating points of intersection 13, 13', 14, 14', 15, 15' and 16,16. These points are situated symmetrically with regard to the original ring plane, as may be seen from Fig. 2. Posts p may be provided connecting 13 to 13, 14 to 14',"15 to 15 and 16 to 16', and it is useful to brace the points of intersection and the ring corners by wires 03. Thus the whole cross member constitutes a substantially ring shaped truss of lentillike cross section.
Instead of spacingaparit the middle art of a formerly in Figs. 1 an 2, you may as well space apart the outer annular part, which means duplicating the ring. girders and providing an inside structure to connect them together. This connection ismade by a ring shaped truss of triangular cross section forming a corridor, as may be seen from Fig. 5, in which 6' and e designate the girders of the (plane ring structure, as one two outer rings and g the additional girders for constituting the ring truss. The inner corners of this ring truss are braced by wires h, shown in Fig. 6. In this figure a longitudinal corridor c on the top of the ship is marked.
Figs. 7 and 8 show variations of this construction. In Fig. 7 two longitudinal corridors i: and 2' are provided and ladders k are shown making the upper part of the ring truss accessible. Fig. 8 gives three longitudinal corridors z, z and 11 Here the shape of the ship is flattened at its lower part between the corridors 13' and 2' which may be useful under certain conditions.
In Figs. 3 and 4 not only the middle part ofthe ring, as in Figs. 1 and 2, or its outer parts, as in Figs. 5 to 8, are spaced apart, but the whole ring structure is duplicated and the two rings situated at a comparatively short distance apart are each provided with intersecting girders e and braced by wires (1. The points of intersection of these girders 13 and 13, 14 and l4, l5 and 15, 16 and 16, are connected by posts h, and the structure is braced by wires f.
It is to be understood thatI do not limit myself to the exact details described or.
shown in the drawing as many variations will occur to persons skilled in the art.
