Description

The technical solution relates to aircraft and can be used to protect the cockpit of a passenger aircraft from illegal entry.

The prior art patent RU 2117903C1, publ. 08/20/1998, which disclosed a bulletproof panel containing plates mounted on the middle part of the support, which have a stiffness of at least 6 * 10 ⁵ n * m / kg. The supports are fixed in the slots of the dampers and are in contact with the body. Dampers are placed between the body and the plates. Between the slots and the supports is a fixing material. The depth of the slots is 0.8-0.9 of the height of the supports. The height and width of the supports are comparable and their sum is 0.8-1.3 of the plate thickness. Moreover, the width and length of the plate is in the range from 5 to 15 thicknesses. The thickness of each plate is comparable with the double thickness of the damper and does not exceed four thicknesses of the body, the thickness of which is determined as 0.1-0.12 of the thickness of the body.

The patent RU 2102688 C1, publ., 01.20.1998 is also known in the prior art, which discloses a multilayer armored barrier containing a substrate of high-strength structural alloy steel, in which a medium-strength or high-strength titanium alloy plate is placed on the outside of this steel plate. On the back of the armored obstacle an additional multilayer bag of ballistic fabric is placed.

There are also known designs of protective partitions used to separate the cockpit from the passenger compartment, described in patents US 6474599, US 3704845.

Closest to the claimed technical solution is a protective partition described in application US 2003/0192989 publ. 10/16/2003, including a partition that separates the cockpit from the passenger compartment. A multilayer ballistic composition made of interconnected metal layer, non-metal layer and fiberglass layer is fixed on the partition with the help of connectors. A bulletproof door, which is equipped with a locking device, is pivotally mounted in the partition.

The disadvantages of the known technical solutions, including the closest analogue, is the significant mass of the structure and structural complexity of manufacturing.

The technical problem solved by the claimed technical solution is the development of a protective partition of the cockpit of a passenger aircraft, in accordance with aviation rules AP-25, capable of providing ballistic and mechanical protection to the cockpit of a passenger aircraft with a minimum weight of the structure.

The problem is solved due to the fact that the claimed technical solution includes a partition separating the cockpit from the passenger compartment, a multilayer ballistic composition, mounted on the partition and a bulletproof door equipped with a locking device. The multilayer ballistic composition is made with cutouts for fasteners that are installed on the partition from the cockpit side and are blocked by influxes from the passenger compartment, with holes made in the partition.

The multilayer ballistic composition can be made of layers of ballistic fabric folded to each other, fixed on the side of the partition facing the cockpit.

Layers of ballistic fabric can be stitched and / or glued together. A folding chair can be mounted on fasteners, with the possibility of horizontal movement.

The technical result of the proposed technical solution is to develop a design for protecting the cockpit of a passenger aircraft from ballistic and mechanical stress when trying to illegally penetrate the cockpit of a passenger aircraft during flight while reducing its weight.

The technical solution of the model is illustrated by drawings:

Figure 2 - separating partition (frame) with fasteners

Figure 4 - view of the protective walls from the cockpit side

Figure 5 - section bb

The protective partition of the cockpit includes a partition 1 that separates the cockpit from the passenger plane, a multi-layer ballistic protection 2 mounted on the partition (figure 3). To enter the crew cabin and exit it, a bulletproof door 3 is pivotally mounted in the partition, opening to the passenger compartment. The door is equipped with a locking device (figure 1).

The partition 1 is made by milling, cutting in the frame dividing the fuselage of the aircraft into the cockpit and passenger cabin, holes 4, with a diameter of 100 mm and an opening for a bulletproof door. To increase the strength of the structure, stiffeners 13 are made on the side of the partition facing the passenger compartment, while the side of the partition facing the cockpit is smooth to install a multilayer ballistic composition.

The multilayer ballistic composition 2 is fixed to the partition using fasteners 6. Moreover, the ballistic composition is fixed around the perimeter, outside the protected zone. The absence of fasteners in the protected area eliminates the possibility of a bullet getting into the fasteners and makes it possible for the multilayer composition to deform at the moment of ballistic impact.

The multilayer ballistic composition 2 consists of layers of ballistic fabric folded together. The number of layers in the composition is from 11 to 30, depending on the selected fabric material (see table 1)

Layers of ballistic fabric can be stitched together and / or glued with a special composition. The multilayer ballistic composition is made with cutouts 10 under the fasteners 9, which are installed on the partition

1, on the side facing the cockpit. The shape of the cutouts 10 in the multilayer ballistic composition correspond to the contours of the fasteners 9.

From the side of the cockpit, a folding chair is installed on partition 1, which, if necessary, moves horizontally along rails

11 mounted on fasteners 9.

From the passenger compartment, cutouts in a multilayer ballistic composition for fasteners are blocked by influx 5 with a thickness sufficient to compensate for the missing multilayer ballistic

composition 2 (figure 5).

To enter the crew cabin and exit it provides a bulletproof door installed in the partition. The door is equipped with a handle 8, a locking device in the form of an electromechanical lock 7. The locking device withstands shock loads provided for by aviation regulations AP-25. and allows using the switch located on the middle panel to unlock, lock and lock the door from the workplace of each pilot.

To control the space adjacent to the cockpit from the passenger compartment, the door has a peephole and a video camera is also provided.

While the aircraft is on the ground, the cockpit door is locked with an electromechanical lock.

During the flight, for safety reasons, the cockpit is locked. In the event of an emergency, the multi-layer ballistic composition 2 absorbs the energy of the bullet, protecting the crew and vital equipment from firearms. The locking device of the door withstands shock loads in accordance with AP-25, preventing attempts of illegal physical entry into the cockpit.

The claimed technical solution can be implemented at the enterprises of the aviation industry.
