Description

The invention relates to a hybrid rigid airship with self-contained aerostatic lift and position control as well as an aerodynamically advantageous shape.

In conventional rigid airships, ballast weight was previously used worked, which determined the height and rate of climb of a rigid airship by dropping it. To sink or landing, air had to be added to the lifting gas.

Through the DT-AS 19 32 264 a rigid airship with a system for lifting gas heating has become known, the supporting body of which is divided into individual gas cells to which heat exchangers are assigned to increase the static buoyancy. Taking along ballast can be avoided as a result; It should be noted, however, that the not inconsiderable weight of the heating system of the payload or the carrying capacity of the airship is lost. Furthermore, only an increase in lift is possible as a result, but not regulation.

Furthermore, OT-OS 20 22 836 has made known a method for obtaining additional buoyancy by means of heat exchangers before the start of airships and flying ships. Also hereby ¹ Bt avoided Ia ballast; however, this concept does not have any advantages for the maneuverability of airships.

DT-OS 14 81 588 discloses an old gas-filled aircraft, which serves as a fuselage, and the dlskuaföralg is trained. Overall, this device is heavier than air;

however, it should be in a deir. Float in the near state Air. Due to its discus shape, the device has excellent aerodynamic properties and buoyancy.

The invention is based on the object in rigid airships to propose a self-contained aerostatic buoyancy and attitude control while avoiding the ballast weight and the To design the airship structure in such a way that it is in the sense of a hybrid airship allows favorable aerodynamic properties and buoyancy.

This problem is solved in that the lifting gas within the rigid airship expand freely and its characteristics match those can adapt to the surrounding air at any time. For this it is necessary that within the hull at least a gas chamber and at least one air chamber is arranged, between which a flexible partition is located, which the Free expansion of the carrier gas is permitted without the carrier gas being mixed with the air. Advantageously the air chamber is connected to the outside air via a valve and / or a pump or fan. This makes it possible to actively regulate the lift in the rigid airship according to the invention. When closing the air chamber and introducing it a relative negative or positive air pressure in the air chamber to the surrounding air is a change in lift and thus causing the airship to climb or sink. When the air chamber is opened, the pressure is equalized to that of the airship surrounding air, with which a constant lift of the lifting gas, independent of the height of rise, is guaranteed.

In terms of a good aerodynamic design of the shape, it is provided that the rigid airship according to the invention has a rotationally symmetrical geometry, preferably in the form of a disc.

The Diskuaform also offers that several gas chambers are evenly distributed in a centrally symmetrical arrangement and in a circular manner are arranged in the hull, and that each gas chamber is assigned an air chamber. This solution has the advantage that at

according to different handling of the individual aerial cameras the rigid airship according to the invention can experience a position control.

It can also be advantageous within the scope of the invention if the engine is in the geometric axis of symmetry of the hull is arranged with a vertical thrust direction, and that the horizontal thrust is generated by thrust deflection.

On the other hand, it should be useful if for the drive of the Rigid airship in the shape of a disc, one engine pair centrally symmetrical is arranged, whose TriebwerkslHngsachaen parallel to The main plane of the disc shape and which are rotatably mounted about the axis of rotation of the hull. This proposal stands out is mainly characterized by the fact that once by appropriate choice of direction the engines a movement of the airship in any direction is possible, and that on the other hand with different Thrust of the engines the desired angle of attack of the airship can be adjusted easily and quickly.

It can also be useful to have heating devices for the lifting gas to be provided, which on the other hand can also be heated up by its own engine exhaust gases. The surface of the Airships must be covered with solar cells in order to use the available solar energy.

The criteria of rigidity and gas-tightness of the outer hull can advantageously be separated, and one can be implemented using, for example, appropriate plastic film material and the other using sandwich construction.

If the air chamber or the air cameras of the rigid airship according to the invention are appropriately inflated after landing, the buoyancy can be partially or completely canceled.

Fig. 1 is a side view of a rigid airship in Diskusforra, the left half of which is cut,

FIG. 2 is a plan view according to FIG. I with partial sections.

The rigid airship 1 according to FIGS. 1 and 2 consists of a rigid outer skin 2 that fixes the outer contour and within which a plurality of gas-carrying gas cannons 3 with these associated air kayaks 4 are arranged. A flexible partition 5 is located between the chambers 3 and 4. 2, six gas cannons 3 are arranged centrally symmetrically within the airship. An air chamber 4 is located below each lifting gas chamber.

As can also be seen from FIG. 1, “is symmetrical to the central one Axis of rotation 6 is arranged above and below the airship 1 each with an engine 7 and 8. The two engines are so connected that they are both together and against each other can be pivoted. The latter causes a change in the angle of attack with the engine thrust unchanged.

The payload compartment of the airship is provided with the reference number 9.
