7 TRAFFIC AIRSHIP OF THE RIGID TYPE Filed Aug. 14; 1929 Shh Patented Sept. 9-, 1930 JOSE! SGHULZ, F BERLIN, GERMANY rnarrrc Amsnrr or THE 31am miner:

Application filed August 14, 1929,-Serial No. 385,727, and in Germany .Tune 7, 1929.

- This invention is based upon the, discovery that with traflic airships of the rigid type fractures of members of the horizontal rudder (for altitude steering), of the vertical 6 rudder (for azimuth steering),'and of the crank-shaft, can be obviated most securely and reliably if the weight of theairship is practically equal to the weightv of the displaced air, that is to say, if the aircraft is 10 neither pretty much heavierthan the air,

like the present flying machines, or pretty much lighter than the air like the present airships.

Another means for the purpose in view,

and also forming a part, or parts, of the present invention is this that the body of the airshi must be provided with fins so desig'ne as to be adapted for use as su portingsurfaces, as well as for use as leakwinds, these fins being arranged at the sides of the body in the horizontal middle plane thereof, and each of them being equipped with a driving propeller, as well as with a horizontal and a vertical rudder. I do not mean to say that the filled airship, ready for use, must be indispensably accurately as heavy as the displaced air; there is a certain permissible deviation u wardly and downwardly which is a valua 1e feature concerning theamount of gas required and the manoeuvring ability of the airship, especially on long journeys.

Throwing ofi of ballast and blowing off of gas will hardly ever become necessary with airships. of the present improved type, and.

it is as'well out of the uestion that airships of this type will ever ecome a puppet of the wind. I

The invention is illustrated dia rammatically and by way of example on t e accompanying drawing, on which Figure 1 is a bottom-view of an airshi desi ed according to this invention, and igure ing planes and are, in the example shown, so

designed that the motors for driving the is a front view thereof, drawn to a greatly reduced scale.

-in their entirety also incommon acting as' supporting planes in the case of a gliding flight.

There are, in the example shown, six lateral fins and two front fins, and each of them is provided with a horizontal rudder 0 and with a verticalrudder d. b are the propellers pertaining tosaid six lateral fins and b are the propellers pertaining to the two front fins. The' horizontal rudders of the two lateral fins at the rear are larger, as shown. Owing to the provision of a plurality of horizontal rudders and of vertical rudders all of them are prevented from excessive strain as can arise, and arises not rarely, with the usual tail rudder known with airships of the types now in use. It is only due to the high-grade material that accidents due to that excessive strain occur comparatively rarely. The tail rudder control members of airships of the usual-design are subject to the entire amount of the stress due to'axial compression, without any subdivision thereof, whereas in the present case such subdivision takes place owing to the provision of that plurality of rudders, as shown and described.

It is also important for thesafe and quick flight of the air-ship that the plurality of propellers is located 3ust in the middle plane oja-the body where their action is most efi'ective in that their driving shafts lie just in said plane. The propellers b are the normally used driving propellers proper, whereas the propellers b serve as spare propellers and are used generally only for manoeuvring Between these cars is the main 0 propellers can be housed in them. All fins for passengers besides the main space at theloo front for the oflicers of the airship, and that it is sus ended below the metacentrum of the body. large vertical rudder f which is also provided partly as a spare rudder and partly for manoeuvring purposes.

Themotors in the cars z and 0 are preferably larger and, therefore, stronger than the motors in the fins. Of these latter motors those driving the first pair of the propellers b (the first pair behind the propellers b) are generally used for turning manoeuvers. All propellers, or the propellers and their driving shafts, may be so designed that they can assume an oblique position with respect to the longitudinal axis of the body of the airship, that is to sa can form horizontal angles therewith. T 's arrangement is particularly suited for turning the airship practicall around the vertical axis of its body, in'whiclz case diagonally located propellers are correspondingly adjusted.
