Description

The utility model relates to aeronautical engineering, mainly naval aviation, and can be used to provide a helicopter's visual landing on runways on take-off and landing runways 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 displays.

Known indicator landing deck (see, patent RU No. 85719 IPC G08G 05/02, publication of 08/10/2009).

The landing deck indicator includes: IR roll indicator; indicator of vertical movement of the runway center runway; digital DSC time indicator remaining to perform safe landing of the helicopter on the runway; the foundation on which the IR and IVP are placed in the form of the letter “T” and DSC; Remote Control; computing unit; information exchange device.

Landing deck indicator works as follows.

When you roll to the left in the range, for example, up to 0 ... -6 ° on the IR, the rows of the left side of the green LEDs are switched on sequentially with accumulation. Accordingly, with a roll to the right in the range, for example, 0 ... + 6 °, the LEDs on the right side of the IR also turn green and accumulate. With a roll value in the range of more than | ± 6 ° |, but less, for example, | ± 10 ° |, the yellow LEDs turn on. When the roll is equal to or more than | ± 10 ° |, the red LEDs turn on.

When the runway moves down on the runway, the rows of LEDs in the form of a green bar graph turn on.

When the runway moves up, the rows of LEDs in the form of a red bar graph are turned on.

Next, the rows of green or red LEDs turn off in accordance with the movement of the runway.

The digital indicator displays the calculated time remaining before the event, in which the runway takes a horizontal position when it moves down.

The disadvantages of this device include: the inability to use the indicator to orient the helicopter in a horizontal position at the stage of helicopter landing on the deck, the lack of information about the ship’s differential, the brightness of the IR and IWP light panels depending on the current value of the roll.

A device is known for indicating the rolling parameters of the runway of the ship (see, “Tulip-VG”, operating manual IZhTsP.676765.005 of the lighting system “Tulip-V1”).

The runway pitch indicator device consists of an IR roll indicator, a runway vertical movement indicator - IVP, a control panel, power switching units for IR light elements, a runway VPP, logic information processing blocks.

IR consists of nine separate light elements arranged horizontally in a line.

IWP consists of 4 light elements arranged in a vertical line. IVP is placed perpendicular to the roll indicator and adjoins it in the center. Two light elements of green color are intended for signaling the runway downward movement, the other two are red - for signaling the runway upward movement.

Incandescent lamps are used as light elements in indicators.

IR is designed to indicate the direction and magnitude of the ship’s side rolling and signaling about pitching, higher than the allowable for this type of helicopter and ship.

IWP is designed to signal the direction and vertical movement of the center of the runway and warn the pilot about the approaching time of changing the direction of vertical movement of the runway.

The IR is mounted on the deck perpendicular to the ship’s longitudinal axis from the stern when helicopters land on the stern. The IWP is installed perpendicular to the horizontal axis of the IR from its center to the stern when the helicopter lands on the stern.

The device displays the pitching parameters as follows.

When the deck moves to the left, the light elements on the left side of the roll indicator turn on sequentially. With a roll to the right - on the right side of the indicator.

If for a given type of ship and helicopter the roll pitch allowed for landing is, for example, ± 10 °, then the first light from the center of the roll indicator lights are turned on if the roll is more than 3 °, but less than 6 ° on the right or left side of the indicator, depending on the direction roll.

At heel angles of more than 6 °, but less than 9 °, the first and second light elements are turned on to the left or right of the center, depending on the direction of rolling.

When the angle of heel is more than 9 °, but less than 10 °, the first, second and third light elements are switched on, respectively, on the right or left side of the center.

At an angle of heel of 10 ° or higher left or right, the extreme red light elements on the left or right sides of the center are switched on. They inform the pilot about roll heights for this type of helicopter and runway.

When the runway moves down, two green light elements of the runway are switched on. 0.5 seconds before reaching the lower position of the deck, these light elements go into flashing mode.

When changing the sign of vertical movement, the green light elements are turned off and the two red ones turn on. The deck moves up. 0.5 seconds before reaching the upper deck position, both lights switch to flashing mode.

The control panel is designed to monitor the health of light elements and control their operation modes. On the remote control, light elements of lower power are installed in the same amount and are also located as light elements in IR and IWP.

The disadvantages of this device include: low resolution of the roll indication, low information content of the vertical direction of runway indication, the inability to use this indicator to maintain the horizontal position of the helicopter.

The light indicator of roll, trim and vertical movement is known (see, Yu.G. Basov, 1993, Light-signaling devices, Moscow, Transport, pp. 269-270, 309), the use of which is aimed at improving the safety of helicopter landing on ship runways at the stage landing and which by the most signs selected as a prototype.

The light indicator includes:

- BIK roll display unit,

- BID trim display unit,

- block display vertical movement BIVP runway.

- information processing and control unit BOIIiU. Structurally, BID and BIVP are combined in one block.

The composition of the BIC includes:

- two-digit digital indicator of the values of the roll of the ship,

- indicators of the direction of the roll of the ship left and right green.

The BID includes:

- single-digit digital indicator display the magnitude of the trim within ± 4 °,

- green indicator to indicate the movement of the deck down with a differential,

- red signaling device - landing prohibition indicator,

- yellow indicator to indicate the movement of the deck up with a differential.

BIVP includes two signaling devices:

- green light to indicate the movement of the deck down,

- yellow warning light to indicate the movement of the deck up.

The device operates as follows.

On the BIC, when the runway is pushed to the left, the pitching direction indicator to the left lights up, respectively, when pitching to the right, the roll direction indicator is turned to the right. The digital display shows the pitching value.

On the BIF, when the runway moves up with the differential on the trim display block, the deck up warning light is yellow, and when the runway is down with the differential, the deck down indicator is green.

If the differential is greater than the permissible, the red landing warning light flashes.

The disadvantages of the known device include: the difficulty of recognition by the pilot of individual numbers that are displayed using digital seven-segment indicators, the short life of the indicators, the inability to use this indicator to maintain the horizontal position of the pilot at the stage of helicopter landing on the runway.

The objective of the invention is to eliminate the disadvantages of the above index roll, trim and direction of vertical movement.

The technical result of the proposed solution is to increase the functionality of the indicator and the safety of helicopter landing, especially at night in the conditions of rolling of the ship due to:

- introducing the UIG true horizon indicator and color coding of the pitching value on the UIG light bar, with which the pilot holds the helicopter in a horizontal position and makes a decision on whether to continue landing on the ship runway or on its termination, providing the pilot with additional and more visual information about the value and the direction of the roll and trim of the ship and the vertical movement of the center of the runway; information about the available time for the pilot to make a decision to perform the operation of approaching (touching) the helicopter to the runway.

The technical result is achieved by the fact that in the indicator landing deck with respect to the prototype introduced the following fundamental innovations:

- the roll display unit is made in the form of a true horizon indicator, consisting of a uniaxial stabilization unit and a bar horizontally mounted on its axis of rotation with a rectangular matrix built into it, consisting of super-bright LEDs, for example, green, and the uniaxial stabilization unit and the bar have inputs - outputs for connecting to multiplex communication lines of information exchange;

- the information processing and control unit is made in the form of an industrial computer having inputs and outputs for connecting information exchange with multiplex communication lines with a bar and a unit for uniaxial stabilization of the true horizon indicator, a color LED screen and a navigation system and in which program modules are integrated: LED brightness control light panels of the strip of the indicator of the true horizon and the LED color screen, control the position of the strip of the indicator of the true horizon; forming on the information field an additional indicator of the direction and size of the ship’s roll a symbol of the current position of the ship along the roll, for example, in the form of a triangle and controlling its movement and color; the formation on the information field of the indicator of the direction and magnitude of the trim of the ship a symbol of the current position of the ship by trim, for example, in the form of a rectangle and control its movement and color; forming on the information field an indicator of the direction and magnitude of the vertical movement of the center of the runway symbol of the current position of the center of the runway in height, for example, in the form of a piston similar to the letter T and controlling its movement and color; calculating the current position of the center of the runway taking into account its location and the magnitudes and directions of all types of ship rolling; calculating the time remaining for the helicopter to land (touch) on the runway and generate digital values of this time on the information field of the available time indicator; generating a landing ban signal and turning on the information field of the available time indicator in red - a landing ban signal; all wired communication lines are made in the form of multiplexed information exchange channels, which on the one hand are connected to a computer and on the other to the components of the indicator and to the ship navigation system;

- a skeleton is inserted into the landing deck indicator, on which the uniaxial stabilization block of the true pointer is placed, and the color LED screen is placed at an angle below the true horizon pointer.

Comparison of the proposed solution with the known technical solutions shows that it has a new set of essential features that, together with the known features, can successfully achieve the goal.

The indicator works as follows.

The initial position of the indicator: the bar 1.2 on the TIG 1 is in a horizontal position. The LEDs on bar 1.2 and ESC 2 do not light. After the submission of commands from computer 3 to turn on the power source 4 and the test control commands UIG 1 and screen 2 go into test control mode. At the end of the test control, information on the technical condition of the UIG 1 and screen 2 and information on the serviceability of the communication channel of the computer 3 with the navigation system 5 is issued to computer 3. If there is no pitching, the UIG 1 bar 1.2 is installed in a horizontal position in the earth coordinate system, and on it are turned on and green LEDs are on. On ESC 2, LEDs are lit, for example, in green around the information fields of direction indicators and roll values 2.1, direction indicators and trim values 2.2, direction indicators and vertical movement center values of runway 2.3 and the available time indicator 2.4, and green LEDs in levels of zero values the rolling parameters 2.1.2, 2.2.2, 2.3.2, and in the information field of the indicator 2.4 the letter or symbol is lit in green.

When on-board rolling, the TIG 1 and ESV 2 tilt together with the foundations 6 and 7 respectively. The uniaxial stabilization unit BOS 1.1, interacting with the ship's navigation system 5, supports the bar 1.2 in horizontal position.

Simultaneously and synchronously with the bar 1.2 on the information field 2.1, the symbol 2.1.4 of the indication of the current value of the roll of the ship is turned on. Moreover, if the pitch angle is equal to or less, for example, | ± 6 ° |, the symbol lights up in green, if the pitch angle is stably located, for example, within more than 6 ° but less than 10 °, then the symbol lights up in a different color, for example , in yellow, if the pitching angle is steadily equal to 10 ° and higher, then the symbol burns different from the previous ones, for example, in red.

Thus, using color coding, the pilot is informed about the pitching value quantitatively. Qualitatively, the pitching angle can be determined by the position of the bar 1.2 relative to the roll bar 2.1.

The indicator of the direction and magnitude of the trim 2.2 works as follows. When the ship moves along the trim, the symbol 2.2.4 of the current value of the trim of the ship, for example, in yellow, is turned on. When the ship moves down the trim, the symbol 2.2.5 of the current value of the trim of the ship of a different color, for example, green, is turned on. Moreover, if the trim value is stably more, for example, | ± 4 ° |, then both symbols (2.2.4 and 2.2.5) are turned on in red.

Data on the heel and trim values are received from the navigation system 5. In computer 3, this data is converted into control signals, which are transmitted via a multiplex communication line from computer 3 to screen 2.

The indicator of the direction and magnitude of the vertical movement of the center of the runway 2.3 works as follows.

According to the navigation system 5 on the values of the vertical, onboard and keel qualities of the ship in computer 3, the height of the runway center is calculated taking into account its location relative to the center of the ship’s pitching and relative to the placement of the sensors of the navigation system. The calculated data are converted into control signals by the position and color of symbols 2.3.4 and 2.3.5 of the current runway center height indication. In this case, when the center of the runway is moving down, the symbol 2.3.4, for example, green, is turned on, and when moving up, the symbol 2.3.5, for example, in yellow. When the amplitude of the vertical movement is more than the specified value, for example, both symbols (2.3.4 and 2.3.5) are turned on in red.

Of particular importance in the deck landing indicator is the digital disposable time indicator 2.4.

Using computer 3, according to a given algorithm, for each pitching cycle, the time is determined through which the runway, moving down, will occupy a position close to horizontal. This is the moment most favorable for the operation of the approaching (touching) of the helicopter to the deck. The fundamental point is that when the pilot maintains the horizontal position of the helicopter, and if you do not take into account the reaction time of the pilot and the time the helicopter moves from its original position to touching the runway, this indication is enough to make a decision about landing (landing) of the helicopter on deck. Under these conditions, the indication of the magnitude and direction of the roll, trim and vertical movement of the center of the runway is redundant.

The advantage of the technical solution is that the pilot is provided with information about the types, direction and magnitude of the runway pitching in an easy-to-read form and in the amount necessary to make a decision aimed at carrying out the operation of landing (touching) the helicopter from the runway or about refusing this final operations.

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