Abstract

1453748 Airships H PAPST 21 March 1974 [21 March 1973] 12532/74 Heading B7W An airship, in which the bow and stern portions of the exterior of the envelope are subjected under flight conditions to a pressure and to suction between such portions, has an envelope 2 divided into separate compartments 3, 5, 4 by partitions 21, 22, the compartments 3 and 4 being interconnected and inflated to a pressure higher than the dynamic pressure at the bow and stern resulting from forward motion of the airship through the air. The partition 21 may be formed from an inflated annular member and a sealing diaphragm (Fig. 3, not shown). The airship may have a braced structural backbone member supporting a cabin and the portion of the envelope surrounding compartment 5 may be double-walled and inflated to the same pressure as compartments 3 and 4. The compartment 5 may be subdivided by a hollow frame continuously supplied with steam to maintain the lifting gas in the compartment at a controlled temperature, and apparatus is described for pressurizing the compartments 3 and 4 and the hollow walls of compartment 5 (Fig. 4, not shown). A rearmounted jet propulsion unit (Fig. 5, not shown) is described.

Description

(54) DIRIJABLE SOFT DESIGN

 The invention relates to the field of aeronautics. A soft airship is known, containing the bow and stern compartments and the middle compartment 1 and 2 located between them. Such a dirigible has compressed gas, and consequently, a reduction in lift force, as well as a large load on the shell due to the velocity head velocity. The purpose of the invention is to ensure the ability of the airship to counter BOS to the action of radial pressure, as well as to ensure the stability of the form of the airship during the dynamic backwater pressure acting on it by creating an increased pressure in the bow and stern compartments compared to the pressure of the middle compartment. The goal is achieved by the fact that the forward and aft compartments of the proposed airship are separated from the middle compartment by impermeable rigid partitions located in the cross-sectional plane of the airship, the diameter of which is 2/3 of the maximum airship diameter. In addition, the gas-tight portions are made of lamellar horn elements, with an inner tube, with eh gas-tightness, the hard partitions on the nose and on the Kpcavnte are connected to the keel frame. The bow and stern compartments are each divided by gas-tight membranes into two gas spaces, one of the COFGS is filled with protective gas. FIG. 1 shows the zones of compression and vacuum on the surface of the airship; in fig. 2 - the proposed airship, longitudinal section. The airship of soft construction consists of shell 1, bow 2 and stern 3 compartments, middle 4 compartments, gas-tight partitions 5 and b, installed in sections with a diameter equal to 2/3 of the maximum diameter of the airship, made of plastic. tinny st.tenovyh elements with an internal frame. Gas-tight bulkheads 5 and 6 on the bow and stern are connected to a keel skeleton 7. In the bow 2 and the stern 3 compartments there are flexible partitions 8 attached to the shell 1 of the airship and the cat section of the compartment into two chambers 9 and 10, which are under pressure from

Claims (5)

Claim 1. An airship of soft construction, containing the nasal and airbays, and the middle compartment located between them, distinguished by the fact that, in order to ensure the ability of the airship to withstand radial pressure, as well as to ensure the shape stability of the airship at impact on him during ^'n davlonygy? ^dp0ra by creating increased pressure in the bow and stern compartments in comparison with the pressure of the middle compartment, the bow and stern compartments are separated from the middle by rigid women in the plane of the cross section of the airship, whose diameter is 2/3 of the maximum diameter of the airship. 2. The airship according to claim 1, with respect to the fact that the gas-tight partitions are made of lamellar wall elements with an internal frame. 3. The airship according to paragraphs. 1 and 2, characterized in that the gas-tight rigid partitions on the bow and stern are connected to the keel frame. . '' 4. The airship according to paragraphs. 1-3, due to the fact that the nasal compartment is divided by means of a gas-tight membrane into two gas spaces, one of which is filled with protective gas. 5. The airship according to paragraphs. 1-4, due to the fact that the aft compartment is divided by gas-tight membranes into two pelvic spaces, one of which is filled with protective gas. 25 Sources of information taken into account in the examination 1.
