The invention relates to the field of aviation, namely to multifunctional single-engine supersonic aircraft.

A multi-mode highly maneuverable aircraft with an integral aerodynamic configuration is known (patent RU 2400402, published 09.27.2010, IPC V64S 30/00, V64S 1/22), containing a fuselage, the middle part of which is smoothly coupled with swept wing consoles, the head and tail of the fuselage, an all-moving vertical and horizontal tail in the rear fuselage. The aircraft is characterized by the fact that the middle part of the fuselage is integrated with the wing center section and is flattened in the vertical direction, and its outer surface in the longitudinal direction is formed by a set of aerodynamic profiles with high construction heights, ensuring the placement of built-in cargo compartments inside the fuselage,

An aircraft with an integral aerodynamic layout is known (patent RU 2440916, published 01/27/2012, IPC B64D 27/20, B64D 33/02), containing a fuselage, a wing, the consoles of which are smoothly coupled with the fuselage, horizontal and vertical tail surfaces, a twin-engine power plant, characterized by that the fuselage is equipped with a bead located above the entrance to the engine air intakes and including controlled rotating parts, while the middle part of the fuselage is flattened and formed longitudinally by a set of aerodynamic profiles, the engine nacelles are spaced apart horizontally, and the engine axes are oriented at an acute angle to the plane of symmetry of the aircraft in the direction of flight.

A multifunctional aircraft with reduced radar signature is known (patent RU 2502643, published 12/27/2013, IPC B64D 7/00, B64D 27/16, containing an airframe, a twin-engine power plant and a set of on-board equipment.

A supersonic aircraft with intra-fuselage cargo compartments is known (patent RU 2583824, published 05/10/2016, IPC B64D 7/08, B64C 30/00), containing a fuselage in the lower part of which large longitudinal cutouts are made for tandemly located cargo compartments.

The technical solutions adopted in analogues do not provide a sufficient level of operational manufacturability and are characterized by increased labor intensity and duration of maintenance. There is no convenient access to the niches of the main landing gear supports (supports), where maintenance units are located. The process of installing and dismantling the engine is labor-intensive and is achieved with the use of additional devices for the upper surfaces. There are a large number of fastening elements on service hatches, which are characterized by the most labor-intensive process of opening/closing hatches, which leads to an increase in the duration of dismantling and installation of service hatch covers. The dense arrangement of blocks and assemblies on board the aircraft leads to the need to dismantle adjacent blocks and assemblies during maintenance and troubleshooting. To dismantle the power plant, partial dismantling of the power elements (frame sections) is required.

The technical problem to which the invention is aimed is to eliminate the shortcomings of aircraft known from the prior art and create a light tactical aircraft that is easy to operate and has the least labor-intensive and time-consuming aircraft maintenance operations.

The technical result of the claimed invention is to increase the convenience and safety of technical operation and maintenance of a light tactical aircraft, including troubleshooting, as well as to reduce the time required to carry out these activities.

The given technical result is achieved by the present invention. A multifunctional single-engine supersonic aircraft contains a fuselage, a wing, a power plant, a canopy with a pneumatic opening system, landing gear supports located in niches, hydraulic and electrical supply systems, maintenance units located in support niches, and on-board equipment located in compartments inside the fuselage. The aircraft is characterized by the fact that the aircraft service units for refueling fuel and oil, connecting a ground source of air conditioning and power supply, ground preparation of weapons, control of cargo compartment doors, grounding and a ground intercom are located in the niches of the left and/or right main landing gear with the possibility of access to him of a person without the use of additional means,

The aircraft is additionally characterized by the fact that the oxygen filling system, the filling system for the pneumatic system for opening the canopy and emergency landing gear, the technological connectors of the on-board equipment are located in the niche of the front landing gear, and the switchgear and contactor boxes are located in the upper part of the niche of the landing gear with the possibility of human access without the use of additional funds.

The invention is illustrated by drawings.

Figure 1 shows a view of the landing gear and aircraft maintenance units (example), located in its niche, where 1 is the connection point for a ground-based power supply source, 2 is the connection point for a ground-based air conditioning source, 3 is a ground-based weapons preparation console, 4 is a control panel. cargo compartment doors, 5 - closed engine oil filling fitting, 6 - centralized fuel filling fitting.

Figure 2 shows a front view of the aircraft, where 7 - the doors of the right and left niches of the main landing gear are presented in the open position.

The niches of the right and left main landing gear of the aircraft are closed in flight by flaps. On the ground, these doors are always in the open position. In the proposed technical solution, the doors of the right and left niches of the landing gear support open to the axis of symmetry of the aircraft, which provides a convenient approach for the specialist to the niche and makes it possible to increase the safety and convenience of aircraft maintenance.

Before performing assigned tasks, the aircraft undergoes pre-flight training, during which the specialist each time needs access to the appropriate aircraft maintenance units.

In the proposed technical solution, aircraft maintenance units (refueling engine fuel and oil, connection point for a ground source of air conditioning, power supply, grounding, ground intercom, ground weapons preparation, control of cargo compartment doors, etc.) are located in the niches of the right and left landing gear at a height , allowing a specialist to conveniently access them from the ground without the use of additional means (from a height of human height). The height interval is from 1.7 to 1.9 m. During operational maintenance, all the necessary aircraft maintenance units are located in places that do not require opening the service hatches and are not equipped with other closing elements.

Some of the aircraft maintenance units (refueling the pneumatic system for opening the canopy and emergency landing gear, refueling and monitoring the oxygen system, technological connectors for on-board equipment) are located in the niche of the front landing gear. The proposed arrangement of maintenance units reduces the duration of work and reduces the labor intensity of maintenance and increases ease of use in general.

As part of periodic aircraft maintenance, diagnostics, repair or replacement of units and assemblies of aircraft systems is required. The aircraft layout also provides for the placement of aircraft units and assemblies depending on their operational reliability and the frequency of maintenance activities.

The aircraft units and assemblies that have the greatest wear during operation and require periodic replacement or require high frequency maintenance (for example, as part of pre-flight preparation or post-flight maintenance) are provided with the fastest and most convenient access with a significant reduction in operating time. For example, DC circuit breakers are easy to access.

In the proposed technical solution (not shown in the drawings), avionics units that require a high frequency of diagnostic, maintenance or repair activities are located inside the fuselage, accessed through the service hatch behind the niche of the right and/or left landing gear in the direction aircraft movements, without the use of additional means, from a height of human height, height interval from 1.7 to 1.9 m.

The service hatch, with the specified avionics units located inside, is closed with a lid using quarter-turn locks for closing/opening. The use of quarter-turn locks made it possible to reduce the total number of fasteners by increasing the step of their installation, as well as reduce the complexity of opening/closing hatches and increase the speed of technical operations.

To carry out maintenance activities, it is not necessary to dismantle the on-board equipment units; it is enough to connect to the technological connector located in the niche of the front support. And to implement repair maintenance measures for units, it is not necessary to dismantle adjacent units and assemblies of other aircraft systems. This solution for avionics units also reduces the duration and complexity of maintenance and increases ease of use in general.

The layout of aircraft system elements, in particular the power supply system (PSS), provides a convenient approach to servicing systems during technical operation. Units of the power supply system (switchgear and contactor boxes), requiring constant inspection and monitoring, are located in the upper part of the OSH niche and have free access.

The proposed design and layout of the aircraft also allows for quick and convenient installation and dismantling of the engine. The aircraft is designed in such a way that dismantling the power plant does not require dismantling other power elements of the aircraft. Dismantling of the power plant is carried out in the “back and down” direction using a specialized trolley containing a carriage and a mechanism for engaging and transporting the engine.

The Irkutsk Aviation Plant handed over a new batch of Yak-130 aircraft to the Russian Ministry of Defense. The Yak-130 combat trainer aircraft has been selected as the base aircraft for training pilots of the Russian Aerospace Forces. It allows you to train pilots of generation 4+ and fifth generation combat aircraft at the most modern level. The Russian turbojet combat trainer Yak-130 was put into service in 2011; Italy also participated in the development of the aircraft, but withdrew from the project after receiving all the documentation; it is produced in Italy under the designation Aermacchi M-346. The aircraft is also produced with modifications in China under the designation Hongdu L-15, the Italian and Chinese version, after modifications, has better characteristics in some respects. A unique feature of the Yak-130 is that the aircraft, thanks to the KSU-130 digital integrated control system, can simulate the handling characteristics of many aircraft, including the F-16, F-15, Rafale, as well as the Eurofighter Typhoon, F-22 and F-35. Unlike foreign analogues, to increase maintainability, Russian aircraft manufacturers have completely abandoned composites in the aircraft; all airframe elements are made of light aluminum-magnesium-lithium alloys. Equipped with two Ukrainian-made AI-222-25 engines, but already localized in Russia, the aircraft reaches speeds of up to 960 km/h, with a flight altitude of up to 12,500 meters and a combat load of up to 3,000 kg. The aircraft's flight range without external tanks is 2000 kilometers. The price of the Yak-130 aircraft for export is 15 million dollars, for the domestic market 7 million, this is cheaper than the Italian aircraft, but more expensive

The Russian heavy attack UAV S-70 "Okhotnik" was spotted in the skies of Russia. Of particular interest is the fact that the plane is not flying in tandem with the Su-57 fighter, but with the Su-30 fighter. That is, the S-70 Okhotnik UAV is being prepared to work together with the Su-30. Previously, many claimed that the S-70 Okhotnik UAVs do not fly, as we see this is not the case. The S-70 Okhotnik UAV is being adapted to work in tandem with other aircraft. Now this is the only video of real use of the drone.

Russian Su-57 fighters have been equipped with new compact cruise missiles located inside the fuselage; at the moment there are no video footage of the new missiles. Presumably the missile was created on the basis of the Kh-101 and Kh-102 cruise missiles, which are used on the Tu-95MS and Tu-160 strategic bombers. The estimated range of hitting targets with these missiles is from 1000 to 3500 kilometers, the missiles are guided inertially and by satellite. Many people immediately wonder how these missiles can be placed inside the Su-57 fuselage. According to the developers, a significant reduction in the dimensions of the new missile was achieved due to the perfectly refined design of the folding wing and internal layout, as well as the use of a new small-sized bypass turbojet engine. Equipping the Su-57 with cruise missiles effectively turns the aircraft into a stealth strategic bomber that is difficult to track. According to Western experts, NATO has already assessed the new threat and is developing a set of measures to counter it.

There is no topic about the Serbian army, so I’m posting it here. Serbia received Russian-made Mi-35P helicopters from the Cypriot Air Force. Mi-35P helicopters were delivered by An-124 aircraft. It is expected that the eleven Mi-35P received will be operated by the 714th Anti-Tank Helicopter Squadron, which already has four helicopters of this type. The Cypriot authorities decided to remove the Mi-35P from service in 2021. due to problems with the supply of spare parts arising from sanctions. To replace the helicopters, Cyprus purchased six Airbus Helicopters H145M light combat helicopters. Serbian President Aleksandar Vucic personally inspected the Mi-35 helicopters sent by Cyprus. According to him, the helicopters will be repainted in a special coloring that matches the landscape of Serbia. The Serbian President also noted that he loves these helicopters for their efficiency and “ominous sound.” “When you hear that intermittent sound, all you can do is run and hide.”

Mini-drones for various purposes have been created for the Russian Su-57 fighter, a source in the Ministry of Defense reported. Whether it will be a swarm of drones or something similar is not yet clear. But as reported, the UAVs will be placed on the external sling and in the intra-fuselage compartment of the aircraft. It is planned that the fighter pilot will launch several drones at once and control this group of drones.
The group will include attack and reconnaissance UAVs, as well as electronic warfare drones. Drones launched from a Su-57 aircraft will allow fighters to break through enemy air defenses by overloading their information channels, as well as strike at air defense systems. Drones for the Su-57 aircraft began to be developed in April 2021.

Russian pilots began to be massively trained in the use of glide bombs. Previously, we talked about the FAB-500 M-62 and KAB 1500 glide bombs; now they are the main strike weapons of Russian aviation, the link to the video is in the comments to the video. Using the wing and rudders, the module installed on the FAB bomb allows you to adjust the flight path to the bomb target and makes it highly accurate. Russia has a colossal number of FAB bombs weighing 250, 500 and 1500 kilograms, so apparently mass training of pilots has begun. To train pilots, a batch of Su-34 bombers was transferred to one of the training centers of the Russian Air Force, which will be used for training pilots. At the same time, the software of the Su-34 aircraft is being finalized, which will make it possible to drop bombs from all types of aircraft maneuvers.
