Description

The technical solution relates to aeronautical engineering, mainly naval aviation, and can be used to provide visual landing of the helicopter on the runways of the runway in difficult weather conditions at night by increasing the volume and quality of information about the ship's rolls presented to the pilot by off-screen display equipment.

It is known that landing a helicopter on a swinging ship runway for a pilot is the most stressful phase of a flight. This is explained by the fact that it must combine 6 degrees of freedom of the helicopter with six degrees of freedom of the runway.

There are basically two directions that are known for improving the safety of helicopter landing on ship swinging runways: the first is the automation of the helicopter landing process through the use of mechanical systems for coupling the helicopter to the deck of the ship and then pulling and fixing the helicopter to the deck; and the second is to increase the level of information support for the pilot with the visual method of helicopter landing on ship runways.

Many types of sea-based helicopters do not have mechanical means of mooring, so landing problems here are solved on the second path.

Known light pointer roll and trim (see, Basov YG Light-signaling devices. M., Transport, 1993, pp. 269-270, 309), the use of which is aimed at improving the safety of helicopter landing on the ship runways at the landing stage. The device has: a roll indication unit with a two-digit digital indicator of roll values built into it and two signaling devices - a roll direction indicator to the left and a roll direction indicator to the right; trim and vertical movement indication unit with five signaling devices built into it - signaling devices for deck movement down, up, landing prohibition, trim direction up and down, and a one-digit digital indicator of trim values.

The device operates as follows.

When rolling the runway to the left on the roll display unit, the roll direction indicator flashes to the left, respectively, when rolling to the right, the roll direction indicator goes to the right. The digital indicator indicates the absolute value of the pitching in degrees.

When the runway moves up (vertically) on the trim and vertical movement display unit, the deck motion indicator lights up, and when it moves down - the deck motion indicator down.

When the differential is down, the trim indicator down lights up, when the differential is up, the trim indicator up. When boarding is prohibited, the boarding ban indicator is activated.

The main disadvantage of this device is the form of presentation of information. So, the pilot, using signaling devices and digital indicators, can hardly determine the time before the beginning of the change of direction along the roll and trim. With even greater difficulty, he can determine the time before the start of a change in the direction of runway height.

The most important drawback of this device is the lack of an off-camera light indication necessary for the pilot to determine the position of the helicopter in the earth's coordinate system, i.e. no indication of the true horizon or true vertical. The absence of such an indication during a night landing in difficult weather conditions (SMU), as a rule, causes the pilots an illusion that leads to a helicopter buildup and, consequently, to flight accidents or catastrophes.

There are other patents and applications for utility models that offer methods and means of providing information to the pilot when landing on a ship runway, for example, such as: indicator of vertical movement of a ship's runway, patent RU No. 123200 IPC G08G 05/02, publication from 12/20/2012; The method of displaying information about the vertical movement of the ship's landing strip during helicopter landing on a ship, patent RU No. 2506654 IPC G09G 03/20, publication of 02/10/2014; indicator of the position of the runway ship, patent RU No. 154199 IPC G08G 05/02, publication of 08/20/2015.

Among them, the landing landing indicator (see patent RU No. 153655 IPC G08G 05/02, publication of 07/27/2015) containing the electromechanical indicator of the true horizon (UIG) consisting of a block uniaxial stabilization (BFB) and the light bar of the true horizon indicator (PUIG), a color LED screen (ESC), an industrial computer that is connected on one side via multiplex communication lines to the ship navigation system, and on the other to the BFB, PUI G and ESC.

All devices are connected to the ship's power source.

The ESC has a light-emitting diode color information field, in which information fields are embedded: the field of the direction indicator and the roll value with the symbol of the current roll value displayed on it; the field of the indicator of the direction and magnitude of the trim with the symbol on it showing the current value of the trim when it moves down and the symbol of the current value of the trim when it moves up; the field of the indicator of the direction and magnitude of the vertical movement of the runway with the symbol on it showing the current position of the center of the runway when it is moving up and the symbol of the current position of the center of the runway when it is moving down, the field of digital indication of the time available to the pilot to make a decision on the mooring operation ( touch) the helicopter to the runway.

The indicator provides a display of the magnitude and period of the three types of pitching, as well as an indication of the true horizon and the time remaining until the horizontal runway is occupied when it moves down and in a roll and trim position that is close to zero.

Thus, the indicator under consideration provides the pilot with information about all the rolling parameters and, in addition, provides the pilot with the opportunity to land in an automated mode using only a digital indicator and a true horizon indicator.

The disadvantages of this indicator include the spatially separated presentation of the information necessary for the pilot to assess the position of the helicopter relative to the runway and the inability to use the true horizon indicator (UIG) directly when approaching the runway, since the pilot is looking down at this moment and thus the UIG light bar leaves his field of vision. The second important drawback is the presence of a digital indicator, the flickering of the numbers of which distracts the pilot's attention from the mooring process.

The objective of the invention is to eliminate the disadvantages of the above indicator.

The technical result of the proposed solution is to provide the information necessary for the pilot to navigate in space when moving the helicopter from the upper point above the runway when landing before it lands on the runway while increasing the information content of the vertical runway indicator due to the introduction of the indication of the predicted runway position at which it is allowed to land on it , color coding of the amplitudes of the trim and the pitch when they move up in one color and when moving down in another.

The technical result is achieved by the fact that, in the pilot’s information support device, when the helicopter lands on a ship, it contains a color LED screen with a pixel matrix structure, the information field of the pitching indicator scale, the information field of the vertical movement indicator of the runway center with built-in symbol for displaying the current value of the runway center height when it moves down or up, the information field of the trim indicator and with the built-in symbol for displaying the current trim value when moving up or down, the light bar of the pilot's orientation in space when landing on the ship runway, an industrial computer with a built-in computing unit, which is connected on one side via a wired communication line to the ship a navigation system that provides the output of the current values of the parameters of the onboard, keel and vertical qualities, and on the other hand, to the LED color screen, and into the computing unit of which Software modules: a module for forming the upper scale of the roll indicator, a module for generating an information field for an indicator of vertical movement of the runway center, a module for generating a symbol for displaying the current position of the center of a runway in height and controlling its position, a module for generating an information field for a trim indicator, a module for generating an indication symbol runway current position by trim, module for setting brightness levels of LEDs on the light screen, and the screen and industrial computer by they are connected to power sources, in addition, the control panel is implemented on the basis of an industrial computer, and the light bar of the pilot's orientation in space when landing on the ship runway is made in the form of a light bar of the true vertical pointer, located vertically on the information field of the screen, and for its formation and control angular position in the computing unit of the control panel introduced software and computing modules: the module for forming the light bar of the true vertical pointer and the module pre generation of information from the navigation system into the control signals for the angular position of the light bar of the true vertical pointer, as well as the module for forming the light bar for the vertical pitch amplitude of the runway center when the center moves from top to bottom in one color, the module for forming the light bar for the vertical pitch amplitude display for the center of the runway for the center runway movement from bottom to top in a different color, the module for forming the light bar of the trim amplitude display when moving from top to bottom in one color, fashion In order to form the light bar for displaying the amplitude of the trim when moving from bottom to top in a different color, in addition, the symbols for indicating the current position of the runway center vertically and the symbols for indicating the current position of the runway along the trim are made in the form of symbols that are identical in shape and color, regardless of the direction of their movement.

In the information field of the screen in its lower part, the information field of the pitching indicator scale and the pitching indicator scale are additionally integrated, the program module for forming the lower pitching indicator scale is introduced into the control unit, and the mooring permission indication symbol is entered into the vertical runway center indicator helicopter to the runway and the corresponding software module for the formation and control of its position.

h _pos - the height from the top to the permitted berth of the helicopter to the runway.

t is the current time.

Points 1, 3 are the vertices of the pitching.

Point 2 is the depression of vertical heaving.

The indicator works as follows.

The indicator consists of ESC 1 and PU 2 based on an industrial computer. The source of data on the pitching parameters is the on-board navigation system 3. Data on the location of the runway center relative to the pitching center of the ship and the ship's building axes is entered into the computer when the product is linked to a specific ship or vessel. PU 2 and ESC 1, and PU 2 and ship navigation system 3 are connected using multiplexed wired communication lines.

After supplying power from the ship's power source 4 to the information field 1.1 of the screen 1, all display elements in accordance with FIG. 2.

In the initial position, the amplitude amplitude of the vertical displacement indicator (IWP) and ID is equal to the height size of the information fields in which the amplitudes of the IWP and ID are built.

In the initial position, the symbol of the current value of the vertical pitch 1.1.3.2 is adjacent directly to the center of the information field 1.1.3, and the symbol of the current value of the trim 1.1.4.2 is located in the center of the information field 1.1.4. The symbol for indicating permission to approach the helicopter to runway 1.1.3.3 is located symmetrically to symbol 1.1.3.2 below the center of the information field 1.1.3.

In the absence of any pitching, indicator 1 maintains a vertical position, zero values of pitching parameters are received from navigation system 3, in computing unit 2.1 these data are processed and converted into control signals, according to which the bar of the true vertical 1.1.2 indicator maintains a vertical position, the amplitudes of trim 1.1.4.1 and pitch 1.1.3.1 are reduced to zero.

Symbols 1.1.3.2, 1.1.3.3 and 1.1.4.2 remain in the same position as the original. Landing is allowed at any time.

In the presence of side rolling, indicator 1 tilts towards pitching. In this case, the UIV bar, controlled by the calculator in accordance with the data from the navigation system 3, maintains a vertical position in the earth coordinate system. The pilot, using the light bar UIV 1.1.2 and the scale of the roll indicators 1.1.1.1 (1.1.1.1a), can determine the approximate value of the roll.

When on-board, longitudinal and vertical pitching, software and computer modules are connected to the work, with the help of which they are determined:

- the position of the bar UIV,

- the predicted values of the amplitudes of the trim and vertical qualities when moving along the wave path up or down. In accordance with this, the trims of the amplitudes of the trim or IWP are included in one or another color. In FIG. 3 shows the colors of the strips when moving downward, and in FIG. 4 - when moving up.

As you know, landing can be carried out when the runway is moving downward, close to the depression, and when the runway is close to horizontal. Therefore, landing is permitted with the green runway bar, as shown in FIG. 3.

The advantage of the proposed technical solution is that the pilot is provided with information about the true vertical from the helicopter’s top when landing to the mooring point and a visual representation of the helicopter’s height and trim position and direction of movement, providing information about the moment of permitted mooring.

The technical and economic effect of the utility model is to increase the safety of helicopter landing on the ship runway day and night during on-board, keel and vertical rocking of the ship while improving the technical and operational characteristics of the UIOL.
