The disadvantages of the above devices include, in particular, the fact that these suspended containers significantly deteriorate the aerodynamic quality of the aircraft, reduce its combat capabilities, especially in conditions of maneuverable air combat.

Also known is the JPADS (Joint Precis ion Air Drop System) parachute system that combines the Precision and Extended Glide Airdrop SYStem (PEGASYS) remotely controlled parachute systems and the US Air Force Precision Airborne Program (PADS). JPADS has highly efficient control systems that are integrated with the control systems of the carrier aircraft. These parachute systems consist of: the parachute itself, a satellite navigation system receiver, a power supply unit with batteries, special software, a parachute line control wiring, and a radio command line control unit for controlling the system from the operator's console, which allows the release of goods from high altitudes to long distances and significantly reduces the likelihood of hitting the carrier aircraft by means of enemy air defense, it makes it possible to deliver goods to the desired point, both by satellite guidance, and without it, by visual reference points. After dropping from a carrier aircraft, from high altitudes, JPADS, using GPS and a guidance system, navigates and controls the flight of the system to the destination, which makes it possible to deliver cargo at a significant distance from the drop point, with an accuracy of 50-75 meters. (Accurate air release [electronic resource]. - URL: https://topwar.ru/43327-tochnava-vvbroska-s-vozduha.html (date of treatment 03/25/2020).

The disadvantage of this system is the low aerodynamic quality of the cargo platform, its weak directional stability, this device does not have an autonomous power plant, which reduces the accuracy of the landing of the descent cargo, reduces the distances that this system can plan, makes it possible to use it only under optimal weather conditions.

Also, the known radio-remotely controlled rescue aircraft "Fregat" suspended under the fuselage of the Tu-16S stern forward, in flight. After dropping the boat, upon its water landing, the parachute was detached and the aircraft crew carried out its guidance at the victims using the Reya radio control system (Tu-16 C [electronic resource]. - URL: http://www.airwar.ru/enc/ sea / tu16s.html (date of treatment 05/18/2020)).

The disadvantages of this suspended aircraft rescue boat can be attributed to the fact that it increased the drag of the aircraft, reducing the range and speed of its flight, and increased its radar signature.

The objective of the present invention is to provide a suspended detachable aircraft container having a parachute system with the possibility of remote or autonomous control, having external contours that reduce the drag of an aircraft container having an autonomous power plant.

The Su-34 fighter-bomber was considered as a potential carrier aircraft presented by the invention. The essence of the invention. Suspended undocked aircraft container, has a body with internal closable compartments (niches) for storing cargo and equipment, having suspension nodes, having a parachute system with the possibility of remote or autonomous control, docking to the aircraft fuselage with the formation of a single integral aerodynamic layout, provided that the contours the outer surfaces of the aircraft container are made using geometry elements of the surfaces of the airframe unidirectional with them. The parachute (which can be made of translucent materials) and the hinge-folding rack located under it with the power plant located on it are placed in the compartment of the aircraft container, which is closed by hinged-folding consoles of the vertical tail, the chord planes of which, when deployed, can deviate from the vertical by an acute angle, and can be made all-rotary, with the possibility of differential and common-mode deviation. The top surface of the aircraft container can be equipped with a solar panel. This air container may have a compartment equipped to accommodate living objects.

The invention is illustrated by drawings (images of the Su-34 fighter-bomber, to which the suspended detachable air container is docked, are taken from the source: M Su-34 (Fullback) aircraft - drawings, dimensions, drawings [electronic resource]. - URL: http: // alldrawings. ru / risunki / item / samolet-m-su-34-fullback-chertezhi-gabarity-risunki-2 (date of access March 25, 2020)).

The Su-34 fighter-bomber was considered as a potential carrier aircraft for a suspended undocked aircraft container. According to the invention (Figs. 1-5), to reduce weight, a suspended detachable air container has a load-bearing body 1, without an internal frame, and a transverse bulkhead separating the cargo compartment and the compartment in which the equipment is located serves to increase its strength characteristics.

The body of the suspended detachable aircraft container 1, as well as the canopy of parachutes 6, 7 and lines 8, 9, can be made of high-modulus ultra-high-molecular-weight polyethylene (UHMWPE) fiber, which is resistant to dynamic loads and has a low surface friction coefficient. Also, this material can have a relatively high translucency, which reduces the visual signature of the parachute system in flight. The body of the suspended detachable aircraft container 1 is docked to the aircraft fuselage with the formation of a single integral aerodynamic layout, provided that the outlines of the outer surfaces of the aircraft container 1 are made using geometry elements of the surfaces of the aircraft airframe unidirectional with them, which makes it possible to avoid an increase in the radar signature of the aircraft and a significant deterioration in its aerodynamic quality (in the position when the suspended detachable air container is docked to the carrier aircraft).

A suspended detachable aircraft container is installed under the aircraft fuselage, between its air intakes. Docking nodes 4 are similar to those installed on the Su-34 fighter-bomber.

The body of the suspended detachable aircraft container 1 has a cargo compartment, from which the instrument compartment is separated by a bulkhead, in which the pilot parachute 6, the main parachute 7 (wing type), the control system, the radio beacon and the batteries are located. On the upper edge of the side walls of the cargo compartment, the lower parts of the power lines of the parachute 8 are fixed and placed in special grooves 3, and their upper part and steering lines 9 are in the instrument compartment, protected from external influences by the consoles of the folding vertical tail 2. Also in the instrument compartment, under the main parachute 7, there is a pivotally folding rack 10 (structurally coupled with the lower part with the bulkhead), with a power plant located on it (for example, a brushless electric motor with a propeller). This pillar 10 consists of two elements: a fixed I-shaped element (coupled to the bulkhead) and an L-shaped element pivotally attached to its upper part, on the bent part of which there is a power plant (Fig. 6). At the base of the I-shaped element there is a hydraulic cylinder 12, to the piston rod of which a guide bar 11 is pivotally attached, the other end is pivotally connected to the movable L-shaped element of the rack 10. When the piston rod of the hydraulic cylinder a 12 is extended, the guide bar 11 raises the L-shaped element struts 10, with the formation of a right angle between I and L-shaped elements and the power plant is brought into the working position.

A suspended detachable air container can be used for high-precision delivery of goods, since, unlike analogues that have a parachute system with the possibility of remote, or autonomous control, using only planning, it has an autonomous power plant that allows you to perform an active flight, and in the case of equipment, in as a cover of the cargo compartment 5, the solar panel used to power the equipment and charge the batteries, can make a very long flight, both in the daytime and at night, up to the full depletion of the motor resource of the power plant.

Such a potentially long stay in the air, low radar, visual and acoustic signature (provided that an electric motor is used), and a relatively low flight speed make it possible to place reconnaissance equipment inside the hull of a detachable suspended aircraft container a 1. Also, these properties make it possible to covertly fly up to the enemy to counteract his electronic systems, to strike at them, if a high-power radio wave generator is installed in the cargo compartment of the body of a suspended detachable aircraft container.

In the case of equipping the cargo compartment with a life support system, a paratrooper with reinforced ammunition can be placed in it (in this case, the front part of the hull of the suspended detachable air container a 1 can be made transparent for visual control of the flight by a person, also, flight control can be duplicated by placing in such a specialized cargo compartment by a joystick connected to the main automatic control system). Thus, a sabotage group with significant, in terms of mass, weapons can be thrown into the rear of the enemy with high precision, covertly. At the same time, this suspended detachable aircraft container can be used, after landing, as an amphibious snowmobile (after detaching the parachute lines 8, 9), driven by the propeller of the power plant 10 and controlled by differential or in-phase deviations of the all-rotating vertical tail consoles 2. The above properties make it possible to use this version of the suspended detachable aircraft container for rescue operations. In the case of using ultra-high molecular weight polyethylene for the manufacture of the hull of the suspended detachable aircraft container a 1 and the parachute 7, it should be taken into account that this material has buoyancy, which can be of great importance for rescuing on the waters.

In the case of using the cargo compartment as an external fuel tank, after undocking from the carrier aircraft, the suspended undocking air container can independently fly to its destination, where it can be reused (this also prevents the detection of traces of the aircraft being over enemy territory, or damage dropped, in as an external fuel tank, an external undocking air container of civilians located on the surface of the Earth).

After undocking from the carrier aircraft of the suspended detachable aircraft container 1, at a given height, the consoles of the folding vertical tail 2 are opened, releasing the pilot chute 6 ejected by the spring, then the main parachute 7 of the "wing" type opens, the articulated folding rack 10 and the power plant located on it, goes into working position. To slow down the opening of the canopy of the main parachute 7, it is advisable to use a slider, which has a lower aerodynamic resistance, in the form of a cross, made of two cross-stitched power bands. Further, the parachute system, according to the course set by the navigation system, makes a controlled landing (autonomously, or controlled from the carrier aircraft), adjusting the course and flight altitude with the steering lines 9. The satellite navigation system, or control from the carrier aircraft, may be unreliable in the conditions of the enemy's use of electronic warfare, as well as, during geomagnetic storms, in mountainous terrain, dense urban development. In this regard, the method of cargo delivery used on the JPADS parachute system is being updated, which has an aerial guidance unit equipped with motors that automatically control the parachute, a video camera that scans the landing site and a control computer that can stabilize the cargo in the air. , determine your location by comparing the image of the earth, obtained from a video camera, with satellite images of the area stored in the computer's memory. Upon completion of orientation, the JPADS system adjusts the flight of the parachute to deliver the cargo to a given point -testing-video / (date of access 05/18/2020)).

Directional stability and balancing about the vertical axis is also provided by the open all-turning consoles of the articulated vertical tail 2, the chord planes of which, when opened, deviate from the vertical by an acute angle, which also provide longitudinal stability and balancing about the horizontal axis. After landing, by radio beacon, the ground crew can find the suspended undocked aircraft container and pick it up for further use.

The advantages of the presented detachable suspended air container:

- the presence of an autonomous power plant makes it possible to perform an active flight, expands the possibilities of both lateral and high-altitude maneuvering, increases the carrying capacity, increases the flight range and landing accuracy;

- also, the above solution allows to ensure the delivery of goods over long distances not only from high, but also from low heights;

- in the case of using a compartment equipped to accommodate living objects, this suspended detachable air container can be used to drop people;

- the contours of the outer surfaces of the suspended detachable air container integrally docked to the carrier aircraft, made using the geometry elements of the aircraft airframe surfaces unidirectional with them, make it possible to reduce its drag and reduce radio signature.

Applicability of the invention. The presented detachable suspended air container was developed taking into account its possible multifunctional use for cargo delivery, radio jamming, aerial reconnaissance, and rescue operations. Accordingly, it can be used both in the military and in the civilian spheres.
