RU223947U1 - The design of an airship of rectangular cross-section with a rigid frame made of galvanized strip with a bent shelf and an outer cladding made of galvanized profiled sheet - Google Patents

Abstract

The utility model relates to the design of an airship with a rigid frame. The rigid airship contains a rectangular-section body with a triangular fairing and a mooring device, as well as a propulsion system. In this case, the airship body consists of a honeycomb frame made of galvanized strips with curved flanges, frames and stringers, as well as an outer lining made of galvanized profiled sheet, attached to the bent flanges of the frames, and an inner lining made of decorative fabric, attached to the bent flanges of the stringers. The technical problem in the claimed utility model is to expand the arsenal of technical means for a specific purpose, and the technical result is to implement the declared purpose. 4 ill.

Description

The rigid airship contains a rectangular body with a triangular fairing and a mooring device, as well as a propulsion system, while the airship body consists of a honeycomb frame made of galvanized strip 0.4-0.8 mm thick with curved shelves, frames and stringers, as well as outer cladding made of galvanized profiled sheet, fixed to the bent flanges of the frames and internal lining made of decorative fabric, fixed to the bent flanges of the stringers. The deck and partitions are made of honeycomb structures made of galvanized strip 0.4 mm thick and lined with non-combustible materials. The movement of the airship is carried out by two ship engines.

The use of honeycomb structures in the frame, deck and partitions makes it possible to significantly lighten the above-mentioned structures in comparison with existing ones made of aluminum, simplify their manufacture and assembly, and expand the arsenal of technical means when creating aeronautical products.

According to information from megaobuchalka.ru/15/11599 html, the use of cellular structures provides “with a relative increase in density of 6%, a change in the design parameters led to an increase in its rigidity by 39 times.” Table attached.

State of the Art:

Existing designs of rigid airships have a round or oval cross-section, a frame made of aluminum frames and stringers, and a lightweight lining made of multilayer special fabric or aluminum sheets.

The proposed options for lens, disk and other sections involve the construction of frames made of lightweight non-combustible materials (aluminum, composite fiberglass, carbon fiber).

All solutions for the construction of a rigid frame are characterized by labor-intensive and divisible costs, a large number of installation connections and, accordingly, loss of load-bearing capacity when operating in vibration conditions.

The difference between the proposed device is:

a rectangular section of the contour with a triangular fairing in which the mooring device is located;

the use of honeycomb load-bearing frame structures made of galvanized strips;

external cladding made of galvanized profiled sheet 0.4 mm thick, secured to the bent flanges of galvanized strip frames with hardware using sealant;

internal lining with insulation in separate zones from decorative fabric, attached to the curved shelves of the stringers;

increased load-bearing capacity and lower labor costs for assembly, with lower weight parameters of existing rigid airships.

Technical result of the proposed utility model:

The technical problem in the claimed utility model is to expand the arsenal of technical means for a specific purpose. The technical result consists in the implementation of the stated purpose.

The task of the technical result when using:

Construction of rigid airships of rectangular cross-section with different load-bearing capacities for use in:

passenger transportation;

cargo transportation;

installation complex for volumetric block housing construction;

placement of radio-electronic systems;

fire extinguishing;

placement of wind generators with a vertical axis of rotation.

Characteristics of the utility model.

The rigid airship contains a rectangular body with a triangular fairing and a mooring device, as well as a propulsion system, while the airship body consists of a honeycomb frame made of galvanized strip 0.4-0.8 mm thick with curved shelves, frames and stringers, as well as outer cladding made of galvanized profiled sheet, fixed to the bent flanges of the frames, and internal lining made of decorative fabric, fixed to the bent flanges of the stringers. The deck and partitions are made of honeycomb structures made of galvanized strip 0.4 mm thick and lined with non-combustible materials.

Implementation of a utility model

The use of honeycomb structures in the frame, deck and partitions makes it possible to significantly lighten the above-mentioned structures in comparison with existing ones made of aluminum, simplify their manufacture and assembly, and expand the arsenal of technical means when creating aeronautical products.

The proposed design of a rigid airship of rectangular cross-section with a rigid frame makes it possible to manufacture and operate the product in various sectors of the national economy as:

passenger vehicle;

vehicle;

mounting device for OBD;

fire-fighting equipment;

communications and electronic warfare;

vertical wind generator.
