Description

The invention relates to training correctable aircraft bombs (KAB) and can be used during training flights in simple and limited weather conditions for training pilots (navigators) in the use of correctable aircraft bombs with thermal imaging, television and laser homing heads.

Known training correctable aerial bombs with homing heads, designed for training a pilot (navigator), for working out joint actions of the crew when using corrective bombs (CAB), consisting of a homing head, body-mechanical part, instrument compartment and tail fairing, and on the hull - For the mechanical part of the bomb, front and rear nodes of the suspension of the bomb to the carrier aircraft and an electrical connector for docking the bomb and carrier aircraft are installed. (See Brusentsov N.A. Naval Aviation. Military Publishing House, 1976, p. 251).

Known training bombs designed to train pilots (navigators) and consisting of a head part, a hull-mechanical part, a tail compartment, a suspension system. (See France, patent No. 2209450, IPC F 42 B 25/00; patent No. 2196065, IPC F 41 H 11/00).

Known (see Fig. 1) is an educational corrective bomb with a television homing head, containing a sequentially docked television homing head (TGSN) 1, instrument compartment 2, tail compartment 3, beam 4 with a front suspension unit 5, a rear suspension unit 6, an electrical docking connector CAB for a carrier aircraft 7, a nose tightening collar 8, a tail tightening collar 9 (see RF patent No. 2093780 from 10.20.97, bull. No. 29, application 95103530/02 from 03/14/95).

TGSN 1 is part of the training adjustable bomb in the form of a separate functional unit, which is a regular TGSN KAB. Instrument compartment 2 is designed to accommodate the on-board automation unit (BBA) of the training CAB and cable cab network. The instrument compartment 2 is sequentially docked with the tail fairing 3 of the training KAB. The beam 4 is designed for suspension sequentially docked TGSN 1, the instrument compartment 2 and the tail fairing 3 on the holder of the carrier aircraft. On the beam 4, front and rear suspension assemblies 5, 6 are installed. On the beam 4, an electric connector 7 is also installed, which provides electrical connection between the KAB and the carrier aircraft. On the beam 4 are attached two coupling clamps (bow 8 and tail 9). With their help, to the beam 4 are attached serially connected TGSN 1, the instrument compartment 2 and the tail fairing 3. The center of gravity of the television homing head is located on the plane of symmetry of the front and rear suspension nodes, and the fairing of the television homing head is made optically transparent in the form of a hemispherical shell with a diameter equal to 0.83 ... 0.87 caliber bombs d, and smoothly mated with the outer spherical metal contour of the fairing in a plane spaced from the front end of the bomb by when standing, 0.21 ... 0.22 caliber, the tail fairing is 0.78 ... 0.82 caliber long bombs, has a lively shape and a diameter of the end part equal to 0.2 ... 0.24 caliber bombs, suspended the beam is made in the length of 3.85 ... 3.9 caliber, and the length of the suspended part is 4.45 ... 4.8 caliber air bombs.

In the prototype TGSN 1 is mounted not cantilever at a considerable distance from the suspension nodes of the standard CAB, but using clamps directly under the suspension nodes 5, 6 of the training CAB. At the same time, the center of gravity of the TGSN 1 is located on the symmetry axis of the front 5 and rear 6 nodes of the KAB suspension, which can dramatically improve the operational characteristics of the training bomb, significantly increasing the number of takeoffs / landings of the training KAB, there are more than 100 compared to 10 takeoffs / landings of the standard KAB.

Suspension nodes KAB 5, 6 and the electrical connector of the docking bomb 7 are mounted on the beam 4 at distances corresponding to the standard suspensions of the KAB.

This training aircraft bomb, made in accordance with the patent of the Russian Federation No. 2093780, is selected as a prototype.

The training correctable prototype bomb, providing the number of takeoffs / landings up to several hundred, allows pilots (navigators) to be trained only on the use of the KAB with television homing heads. In low light conditions (less than 50 lux) and at night, the training corrected air bomb cannot provide training for flight personnel.

This training KAB does not allow for training on the use of KAB with thermal imaging and laser GOS.

In addition, the fairing of the training KAB is optically transparent in the form of a hemispherical shell. The shape of such a fairing is selected based on minimizing the frontal resistance of a standard KAB with a television seeker.

In the proposed universal hanging combined training corrective bomber, the cowl is selected in the form of a flat plate, which greatly simplifies the manufacture of the cowl. For a carrier aircraft, a slight increase in the drag of the training aircraft is not significant.

The expected technical result consists in the creation of a universal suspended combined training correctable air bomb for round-the-clock (day and night) training flights using thermal imaging, television and laser KAB in both simple and in difficult conditions.

To solve this problem, in the training KAB prototype, a “radiation-signal” information converter placed on a triaxial gyrostabilizer and including three information channels is placed in the television GOS, which includes thermal imaging, the spectral sensitivity range of which corresponds to the far infrared range of 8 ... 14 μm, television the spectral range of which includes an optical 0.4 ... 0.74 μm and a near infrared range of 0.74 ... 1.1 μm, and a laser direction finder operating at a wavelength of 1.063 μm, and the fairing is made as a flat glass of se enida zinc thickness of 15 to 20 in the form of a square plate with a side of a square of 220 ... 260 mm with rounded edges of a square with a radius of 38 ... 42 mm, and the downwardly inclined to the axis of the training bombs at an angle of 30 °.

In Fig.1 shows a General view of the training of the adjustable bombs of the prototype.

Figure 2 shows a General view of the proposed universal outboard combined training adjustable bombs.

Television GOS 1 is part of the educational corrected prototype air bombs (see figure 1) in the form of a separate functional unit, which is a regular TSSS KAB. Instrument compartment 2 is designed to accommodate the on-board automation unit of the training CAB (BBA) and the cable network of the CAB. The instrument compartment 2 is sequentially docked with the tail fairing 3 of the training KAB. The beam 4 is designed for suspension sequentially docked TGSN 1, the instrument compartment 2 and the tail fairing 3 on the holder of the carrier aircraft. On beam 4, front 5 and rear 6 suspension units are installed. An electric connector 7 is also installed on the beam 4, which provides electrical connection between the KAB and the carrier aircraft. On the beam 4 are attached two coupling clamps (bow 8 and tail 9). With their help, to the beam 4 are attached serially connected TGSN 1, the instrument compartment 2 and the tail fairing 3. The center of gravity of the television homing head is located on the plane of symmetry of the front and rear suspension nodes, and the fairing of the television homing head is made optically transparent in the form of a hemispherical shell with a diameter equal to 0.85 ... 0.87 caliber training bombs, and smoothly mated with the outer spherical metal contour of the fairing in a plane spaced from the front end of the training Viabombs at a distance of 0.21 ... 0.22 caliber, the tail fairing is made with a length of 0.78 ... 0.82 caliber, has a lively shape and a diameter of the end part equal to 0.2 ... 0.24 caliber training bombs , the suspended beam 4 is made of a length of 3.85 ... 3.9 caliber, and the length of the suspended part of 4.45 ... 4.8 caliber training bombs.

A universal suspended combined training correctable bomb (see Fig. 2) contains a sequentially docked information compartment 10 with a radiation-to-signal converter mounted on a triaxial gyrostabilizer and including three information channels: thermal imaging, television and laser, instrument compartment 2, tail fairing 3 , a suspension beam 4 with a front suspension assembly 5, a rear suspension assembly 6, an electrical connector for connecting the KAB to a carrier aircraft 7, a nose coupling collar 8, a tail coupling collar 9.

The transparent cowl fairing is made in the form of a flat square plate 11, 15 ... 20 mm thick with a square side of 220 ... 260 mm with rounding at the edges with a radius of 38 ... 42 mm, made of zinc selenide. This material, according to the data of Scientific Research Institute of Technical Glass, provides high transparency in a very wide spectral range from optical (0.4 ... 0.74 μm) to far infrared (8 ... 14 μm), ( prospectus of the company NITS OJSC, e - mail: intg@orc.ru).

In this case, a square plate 11 made of zinc selenide is fixed in the end part of the nose compartment 12 of the KAB, which is a metal plate with a square side of 260 ... 310 mm with rounded edges with a radius of 38 ... 42 mm and offset 30 ° relative to the section of the KAB way down.

The bow compartment 12 itself is smoothly interfaced with the spherical tip of the information compartment 12, made with a length equal to 2.07 caliber air bombs.

The process of training the crew in the combat use of the KAB consists in working out the following sequence of actions:

- the conclusion of the carrier aircraft in the target area;

- capture the target sighting and navigation system of the aircraft (PRNK);

- displaying a thermal or television image of the target and the signal from the laser direction finder on the screen of the standard television indicator (IT) of the carrier aircraft;

- additional targeting using PRNK organs of the carrier aircraft according to the thermal imaging (television) image of the area formed by the radiation-signal converters of the information compartment 10;

- translation of information channels (thermal, or television, or laser) into the capture and auto tracking mode of the selected target.

The proposed universal suspended combined training corrective bomb allows for round-the-clock training of the flight personnel of front-line aviation on the use of thermal imaging, television and laser spacecraft in simple and limited-weather conditions.

This training KAB is economical, since its operation life corresponds to several hundred take-offs and landings.

The KAB optical fairing provides high transparency from visible light to electromagnetic radiation from bodies in the far infrared range. The fairing is made in the form of a flat plate of zinc selenide, which significantly reduces its cost compared to a spherical fairing.

A shift of the optical axis of the information channels by 30 ° down the pitch is more optimal than the prototype for the search and auto tracking of ground targets.

The proposed universal suspended combined training corrective bomb has a mass of approximately 85 kg, is not discarded even during an emergency landing of the carrier aircraft and allows you to increase the allowable time of the carrier aircraft with the training bomb, which is also significant.

The invention allows to significantly reduce the cost of training the flight personnel of the Air Force on the use of high-precision adjustable bombs.
