Description

A useful model of a lenticular hybrid airship relates to aeronautics and, in particular, to the constructions of lenticular airships with a semi-rigid structure using power plants for take-off, landing and stabilization at attack and roll angles. Currently, airships of various shapes and purposes are known [1].

As a prototype, a semi-rigid controlled aerostatic aircraft was taken [2]. The aircraft shown in the prototype, including a disk-shaped body located on the periphery and forming a rigid power frame forming the edge of the body, mounted on the external frame using an internal suspension made of longitudinally rigid elements equipped with devices for changing their tension, a hollow rigid internal power core; the outer shell, made in the form of two shells: the upper and lower; gas cylinders located in the internal volume of the body, filled with gas lighter than air; a cargo compartment located in the inner skeleton, mounted on the outer frame and forming a relatively sharp fairing edge of the body; control cabin.

The design of the utility model of the lenticular hybrid airship has the following differences from the prototype:

1. The case is made of lenticular shape, since a disk-shaped (ellipsoidal) shape with a soft shell is possible only with a height to diameter ratio of 0.6, that is, with a desired ratio of 0.3-0.45, the soft shell will have radial folds, there will be no wrinkles only when using the upper and lower parts of the shell of an ellipsoid with a ratio of 0.6 giving, when combined, the selected ratio of height to diameter is less than 0.6;

2. The external power ring is formed of a triangular power truss, forming a sharp edge at the entrance of the air flow to the housing and allowing to mark various equipment inside the truss;

3. There is no internal suspension of longitudinally rigid elements and devices for changing their tension as an extra element, since the tension of the outer shell is sufficient to hold the gondola of the cargo compartment;

The unmanned airship is designed to hover in a limited area of airspace in order to ensure the operation of search and fixing equipment.

The proposed utility model in a manned version can be used to deliver bulky heavy loads directly from the manufacturer to the consumer. The airship of this design can land on a limited area and when fixed by stretch marks, be stationary at different wind directions. In the embodiment of the shock absorber in the form of a torus, the airship can independently land on the ground or water when using the torus as a suction cup. When moving the airship and taking off, the torus can be used as an air cushion. In flight, to reduce aerodynamic drag, the torus can be retracted into the gondola of the airship.

The technical result is achieved due to:

1. The use of the lenticular hull of the airship formed by an external rigid power ring made in the form of a triangular truss in cross section and an external air-filled soft shell formed of two parts of an ellipsoid with a height to diameter ratio of 0.6, which, unlike the prototype with a height-to-diameter ratio of 0.3, this avoids the formation of radial folds of the shell and maintains a high load on the inner rings in order to use them to suspend a cargo nacelle;

2. The internal gas shells are attached to the nacelle by means of internal rigging, and are also attached to the outer ring in order to prevent their displacement during tilting of the airship, unlike the prototype, there is no fastening to the outer shell using hooks and loops, since this design will not allow replacing the lost tightness of the gas shell with the shell of the airship;

3. Four marching power plants are located in pairs above and below the external power ring at the maximum distance of the power ring from the longitudinal axis of the airship, which improves directional control due to different traction and reduces the load on the ring due to the absence of torque and bending moments, and also eliminates the impact jets on the shell;

4. Four lift-stabilizing power plants are attached to the power ring and provide lifting in an overloaded and descent in lightweight conditions, as well as stabilization of the airship at the angles of attack and roll, the distance between the power plants in the transverse direction is less than the distance in the longitudinal direction, while the feed plants are located outside action of jets from marching installations.

Due to their low efficiency, stabilizers are not installed at speeds of up to 20 km / h.

The drawing of the lens-shaped airship is shown in the figure.

The airship consists of an external air-filled soft shell 1, the shape of which is ensured by an external rigid power ring 4, on which the marching power plants 11 and the lift stabilizing devices 12 are mounted.

In the upper part of the shell there is an inner upper power ring 5 fixed to it and to the lower part of the shell an inner lower power ring 6 is attached to which the nacelle 9 is attached, and the upper part of the nacelle, by means of the conical rigging 2 and the central power unit 7, is held by the upper inner power ring.

Inside the shell there are gas shells 3 connected to the nacelle with the help of an internal rigging 13. For lifting people to the upper part of the shell, if equipment is installed there is a shaft 8.

A torus shock absorber 10 is attached to the bottom of the nacelle, also used as an air cushion and suction cup.
