Description

The invention relates to aircraft equipment, namely to the design of removable suspended aircraft containers for the internal deployment of aircraft weapons (container-type suspension point adapter (ATP-KT)) of tactical aircraft and is intended to accommodate a wide range of aircraft weapons installations with guided aircraft defeats, including "air-to-air" and "air-to-surface" short and medium range and towed radar traps.

An aircraft container is known (SU 1823371, publ. 03/27/1995, IPC B64D 1/08), containing a body with a power set, suspension units for the aircraft and front and rear fairings.

A hanging container for an aircraft is known (RU 2739018, publ. 12/21/2020 IPC B64D 9/00), containing a bracket with attachment points, on which fairings with locks are installed.

The disadvantages of the above known technical solutions is the inability to accommodate and use a wide range of weapons of various classes, the lack of radar protection and protection against high-temperature effects.

At present, two-post adapters of suspension points are used on tactical aviation aircraft to accommodate, as a rule, air-to-air and air-to-surface weapons, mainly of an unguided type. In this regard, the range of means of destruction placed on two-post adapters for aircraft suspension points is limited mainly to aviation weapons for bombing.

Such a limitation on the range of means of destruction placed on two-post adapters of hardpoints leads to a reduction in the combat effectiveness of the aircraft in those tasks where it is expected to meet with enemy aircraft, since the volume that could be occupied by means of destruction of the air-to-air class is reduced due to exclusion of two (or more) suspension points for aircraft weapons. Moreover, when countering a technologically advanced enemy with advanced radar reconnaissance, the presence of additional air weapons on external hardpoints worsens the radar invisibility of the aircraft and its aerodynamic characteristics.

The proposed technical solution is aimed at enabling the aircraft to carry an increased number of a wide range of aviation weapons that increase combat effectiveness, without making changes to the design of the aircraft's bearing surfaces.

The problem to be solved by the invention is to eliminate the shortcomings of the prior art, to provide the possibility of placing a wide range of guided weapons of various classes and increasing their number, to ensure the radar invisibility of the aircraft with such placement, as well as to increase the range and duration of the aircraft flight for by reducing the aerodynamic resistance of aircraft weapons located outside the oncoming air flow.

The technical result to which the invention is directed is to ensure the expansion of the functionality of the aircraft to solve combat missions, increase the combat effectiveness of the aircraft, reduce radar visibility, and also increase the safety of the use of certain types of aviation weapons.

The given technical result is achieved by the present invention. Removable suspended container of aircraft armament contains a body with a load-bearing frame, nose and tail aerodynamic fairings and a pylon for suspension of the container on the aircraft suspension point. The container is characterized by the fact that inside the container body in its upper part there are communications for controlling the use of the payload and load-bearing frame units for securing the payload, including flanged hinge assemblies for aircraft weapons installations, containing at least 12 studs for attaching aviation weapons installations with air-to-surface missiles and “ear-fork” attachment units, in the amount of at least 24 pieces, while the “ear-fork” attachment units are located in two blocks of 4 pieces. in a row perpendicular to the axis of symmetry of the container in the front and rear parts of the container body with an equal distance between the fastening elements for installations of aviation weapons with air-to-air missiles, and two blocks of 8 pcs. in the front and back of the container arranged in the shape of a square with fasteners arranged in 2 pcs. in its corners, for installations of aviation weapons with towed radar traps, while the lower part of the container body is equipped with a hatch and flaps closing it, each of which is equipped with a flap drive located inside the container body, the width of the hatch opening is less than the width of the lower part of the container body, suspension pylon The container contains connectors for connecting the container to the on-board systems of the aircraft, while all elements of the container design are made with a heat-resistant coating, and the outer surface of the container additionally contains a radio-absorbing coating.

The invention is illustrated by drawings, where in Fig. 1 shows a removable hanging container for weapons of aircraft with placed air-to-surface weapons; 3 shows a removable hanging container for aircraft weapons with towed radar traps placed, in Fig. 4 schematically shows the hinge points of the "ear-fork" type aircraft armament installations.

In FIG. 1, 2, 3 positions are marked: 1 - nose cone, 2 - suspension pylon on the suspension point, 3 - connectors for connection to the aircraft onboard systems, 4 - tail fairing, 5 - payload, 6 - flap drives, 7 - aircraft installations weapons (give a design), 8 - area for placing communications for connecting the payload, 9 - doors, 10 - output device for aviation weapons with an active start. In FIG. 4 schematically shows the hinge points of the "ear-fork" type, in the amount of at least 24 pieces, while the hinge points of the aircraft weapons installations with the "ear-fork" type mounts are located in two blocks of 4 pieces. in a row perpendicular to the axis of symmetry of the container in the front and rear parts of the container body with an equal distance between the fastening elements for installations of aviation weapons with air-to-air missiles (A), and two blocks of 8 pcs. in the front and rear parts of the container, arranged in the shape of a square with fastening elements located in its corners, 2 pieces each, for installations of aviation weapons with towed radar traps (B).

Detachable suspension container for aircraft armament is structurally a container placed on a standardly provided aircraft suspension point under the wing.

The nose (1) and tail (4) fairings of the container are designed to reduce aerodynamic drag.

The container has flaps (9) for suspension and removal of aircraft armament and its combat use in the framework of the assigned tasks, as well as to provide access to the aggregates of aircraft armament installations, including for maintenance. The flaps are in the closed position in flight to minimize aerodynamic drag and ensure a low level of radar visibility of the aircraft. Directly before the separation or loading of aircraft weapons, the flaps for opening / closing are controlled using actuators (6).

The payload (5) is placed on the aircraft weapons installations (7), which are suspended on the load-bearing units of the container frame, transferring the load from the container to the suspension points under the aircraft wing. The power units of the container frame are provided with fastening units. Flanged hinge assemblies for aircraft weapons installations contain at least 12 studs for attaching aircraft weapons installations with air-to-surface missiles. Attachment units of the "ear-fork" type in the amount of at least 24 pcs. In this case, the attachment points of the "ear-fork" type are located in two blocks of 4 pcs. in a row perpendicular to the axis of symmetry of the container in the front and rear parts of the container body with an equal distance between the fastening elements for installations of aviation weapons with air-to-air missiles, and two blocks of 8 pcs. in the front and rear of the container arranged in the shape of a square with fastening elements located in its corners, for installations of aviation weapons with towed radar traps.

The container is suspended on a suspension point using a pylon (2).

With the help of electrical connectors (3) located on the pylon (2), electrical docking and information interaction of the on-board equipment of the aircraft and aviation weapons for their use is provided (control for solving tasks for the use of weapons).

In the zone (8) of the container, communications are placed to control the use of weapons.

The proposed configuration of a removable suspended container for aircraft armament provides the necessary space to accommodate two weapons, as well as the necessary clearances between the weapon and the movable and fixed elements of the container structure, such as doors, elements of the control system for opening and closing container doors, aircraft weapons installations, etc. .p., which allows you to place, transport and use air-to-air guided weapons. These gaps are selected, including taking into account possible deformations of the container structure from flight loads and external influencing factors.

Improving the safety of the use of certain types of air-to-air weapons (medium or short range) in an extended range of altitudes and flight speeds is achieved through the possibility of using the necessary range of replaceable aircraft weapons installations that provide the necessary parameters for separating aircraft weapons from the container compartment, placement of mobile devices to ensure the launchers are removed from the theoretical contour of the container to reduce the impact of the gas-dynamic jet of the launching product, as well as the application of radio-absorbing coatings on the entire outer surface of the container and heat-resistant coatings on all elements of the container that protect against high-temperature abrasive effects during the active launch of aircraft weapons medium or short range air-to-air class.

An additional increase in the range and duration of the aircraft flight is provided by reducing aerodynamic drag due to the provision of the container with nose and tail aerodynamic fairings, which also makes it possible to reduce the fuel consumption of the aircraft.

The design of the container, namely the presence of various types of weapon attachment points, makes it possible to change aircraft armament options when operating in combat units.
