Description

The invention relates to aircraft and is intended for use in the construction of highly maneuverable multi-purpose aircraft operating in a group.

A well-known training aircraft having a fuselage, wing air intakes bounded by a wing, landing gear, a power plant with engines, horizontal and vertical tail, as well as a set of on-board equipment (RU 2144885 C1, B 64 C 3/14, 01/27/2000).

The disadvantages of the known aircraft are determined by low transport efficiency, unsatisfactory flight performance, lack of structural elements necessary to perform the functions of a multi-purpose aircraft.

Closest to the proposed one is a multi-purpose aircraft containing a fuselage with a cockpit in the bow, wing air intakes bounded by a wing, landing gear, a main power plant with two turbojet engines located in the middle of the fuselage, horizontal and single-keel vertical plumage, an auxiliary power plant that provides launch engines of the main power plant, power supply of airborne equipment on the ground and in flight, compressed air supply to the aircraft systems in the rear part of the fuselage, the bow of which is made with a removable nose compartment and pivoting flaps fixed to the corresponding parts of the wing, made with the possibility of overlapping the axial inlets of the corresponding air intakes and the corresponding additional inlets in the wing, as well as a complex of on-board equipment (RU 2210522 C1, B 64 From 1/36, 08/20/2003).

However, this aircraft and, in particular, its complex of avionics do not provide effective action as part of the group.

The objective of the invention is the creation of a multi-purpose aircraft with enhanced maneuverability. The technical result is to increase the effectiveness of group actions.

To solve this problem, a light multi-purpose aircraft with enhanced maneuverability was proposed, containing the fuselage, wing, plumage, landing gear, the engines of the main power plant, air intakes with channels bounded by a wing, on which a flap is fixed with the possibility of rotation and flush with the upper surface of the wing, an auxiliary a power plant located in the rear of the fuselage across its longitudinal axis, and a multi-position integrated complex of on-board equipment, including yourself:

information exchange system;

on-board digital computer system for flight control and combat training operations;

external storage device and information input system;

inertial system;

radio engineering system of short-range navigation and landing and the defendant of the air traffic control system and state recognition;

automatic radio compass;

radio altimeter with transceiver and antenna device;

marker receiver;

an integrated aircraft control system with system consoles installed in the cockpit and operator;

armament control system with system consoles installed in the cockpit and operator;

integrated systems of electronic indication, control and aiming;

alarm information boards installed in the cockpit of the pilot (and operator);

satellite communications system;

double redundant control system for general aircraft equipment;

airborne objective control system;

connected radio station;

aircraft intercom module;

power supply system;

external and internal lighting equipment;

a comprehensive emergency exit system, as well as a double redundant electronic power plant control system.

At the same time, the information exchange system is divided into three independent multiplexed information exchange channels, radial communications are made between the computer system and the control system for general aircraft equipment, as well as the complex electronic display, control and aiming system and the integrated control system, the latter being able to provide a single information field for solving aircraft problems in a group.

At the same time, the integrated complex of on-board electronic equipment during group operations with light multi-purpose aircraft is one-position, because the crews are connected with each other and the group (s) commander only with the help of an integrated airborne communications complex having radio engineering and telecode communication modules. Radio communication provides voice communication, the telecode is divided into types of messages: orders and reports, guidance and target designation, signals and standard forms (it is not effective for high-quality transmission of television images between the group’s aircraft due to the wide-ranging antenna action).

These aircraft connections in the group are not enough to turn their totality into a single system of functionally connected systems of several spatially separated control objects, the radar sensors of which form a single system (see A.I. Kanaschenkov, V.I. Merkulov, O.F. Samarin “ The appearance of promising airborne radar systems ”, p. 54), necessary for the effective solution of tasks in modern dynamic conditions of military operations.

To provide increased maneuverability of a light multi-purpose aircraft by creating a single information field between the planes in a group using high-frequency television, thermal imaging and radar control connections, the invention provides the expansion of the functionality of an integrated complex of on-board equipment of a light multi-purpose aircraft.

For this, the integrated complex of on-board equipment of a light multi-purpose aircraft additionally includes a multi-position module of the on-board complex of electronic equipment associated with a single-position IR avionics, with an integrated on-board communications system, with an antenna system for all-round viewing, providing circular reception and transmission of information from one aircraft to another.

d) filters 86, combining the circuits 71 and 78.

The operation of a multi-position integrated complex of avionics of a light multi-purpose aircraft can occur in two modes: single-position and multi-position.

Work in the single-position mode corresponds to (patent of the Russian Federation No. 2215668 of November 10, 2003).

Work in the multi-position mode (see figure 1) occurs using the multi-position radar circuit 71 and / or the multi-position circuit 78 OE OPS (television or thermal).

The transmission of information using the multi-position radar circuit 71 is as follows.

Available information about the target is reflected, for example, MFCI 7 and can be transmitted - through a synchronizer 72, a generator 73, a transmitter 74, a switch 81 - using, for example, transceiver headlights 82-85 to another plane. Each aircraft has its own letter frequency passed through the filter 86.

The synchronizer 72 provides the radar signals from the target and signals characterizing the angular position of the radar axis of the radar beam shape necessary for modulating the oscillations of the transmitter 74. The generator 73 generates high-frequency pulses.

Oscillations from the transmitter 74, passing through the switch 81, are emitted using the antenna 82-85 in space. At the same time, the synchronizer additionally provides the same angular position of the antennas 82-85 with the axis of the radar pattern for the group commander’s aircraft (for him the target in this case is a group of planes), and for planes of the group (groups) - the direction of the headlamp 82-85 to the group commander’s plane .

The switch 81 switches the system to receive and transmit information.

Through the same antenna system 70, using, for example, the HEADLIGHTER 82-85 working through the switch 81 for reception, the information enters the receiver 75 filters 86, the computer 28, processing these signals.

At the same time, the analyzer 76 sorts the received signals by sending them to various channels: trigger pulses and video signals are fed through the digital computer 28 to the indicator, for example 7, and the rotation signals of the antenna pass through the converter 77, where they take the form necessary to reproduce the required type of scan, then these signals are sent to an indicator, for example 7.

Such information is received by the group commander from all aircraft in the group and is simultaneously displayed on the MFCI screen, for example 7 (see Fig. 6). At the same time, the BCCM 28 according to the program laid down in it provides an overlay of images from the MFCI of the aircraft of the group on the image on the MFCI 7 screen on a reduced scale (Fig. 6 - positions A, B).

Information from other aircraft can be displayed on a separate MFCI, for example, with a two-seater cabin on the aircraft of the group commander.

To transmit video from OE OPS 30, 32, information through the video image transmitter 80, switch 81 and antennas 82-85 is transmitted, for example, to MFCI 8 group leader through the video receiver 79, filters 86, BTsVM 28.

Block multiposition 69 and antenna system 70 are equipped with all light multi-purpose aircraft of the group.

The presence of a light multipurpose aircraft multi-position block 69 and antenna system 70 provides technical results:

- improving the completeness and accuracy of information about the tactical situation by reviewing large sectors of space both in depth and in the width of the combat zone (see Fig. 5) by a group of light multi-purpose aircraft and transmitting the received information, for example, to the commander of a group (s), which “Sees” the course of the operation through the eyes of the pilots of the attacking aircraft;

- almost instant information transfer ensures the work of the commander in assessing the situation in real time;

- knowledge of the complete information of the enemy on the depth and width of the engagement (with a corresponding number of planes in the group - Figure 5 is a diagram for simplicity reacting 3 ^x planes per group) provides: the possibility to create a preponderance of power in the right direction at the right time; favorable opportunities for mutual protection; more organized conduct of hostilities;

- receiving information from another aircraft allows the attacking aircraft to operate in radio silence mode, which increases the effectiveness of its actions due to the surprise of the attack, in addition, increases its survival;

- the optimal solution to the problem of target distribution of aircraft;

- rational use of various information systems (radar, television, thermal imaging).

Due to the connection of the multi-position 69 unit with the on-board communication complex 44, the target image can be transferred to the group commander indicating its exact coordinates.

Thus, the inclusion of a multi-position infrared avionics system avionics, which solves a wide range of tasks, provides increased maneuverability of a light multi-purpose aircraft during group operations.
