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 ways to increase 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 helicopter and then attracting and fixing the helicopter to the deck, and the second is to increase the level of information support for the pilot 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, Yu.G. Basov, 1993, Light-signal 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 landing stage. The device has a roll display unit with a two-digit digital indicator of roll values and two signaling devices built-in to it - a roll direction signaling device to the left and a roll direction signaling device to the right; a trim and vertical movement display unit with five signaling devices built-in - 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 disadvantage 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. lack of 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, accordingly, to flight accidents or catastrophes.

Known technical solutions that offer methods and means of providing information to the pilot when landing on a ship runway, for example, an indicator of vertical movement of a ship runway, patent RU No. 123200 IPC G08G 05/02, publication of 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 G09G03 / 20, publication of 02/10/2014; The indicator of the position of the runway is ship, patent RU No. 154199 IPC G08G 05/02, publication of 08/20/2015;

Among them, the pilot landing indicator (see RU patent No. 153655 IPC G08G 05/02, publication of 07/27/2015) containing the electromechanical indicator of the true horizon (UIG), consisting of uniaxial stabilization unit (BFB) and the light bar of the true horizon indicator (PUIG); LED color screen (ESC); industrial computer, which is connected on the one hand via multiplex communication lines to the ship navigation system, and on the other hand to the biofeedback system, PUIG, 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 integrated, a direction indicator field and a roll value display with a 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; digital indication field of the time available for the pilot to make a decision on the operation of approaching (touching) the helicopter to the take-off and landing site.

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 impossibility of using the UIG directly when approaching the runway, since the pilot is looking down at this moment and thus the UIG light bar leaves its field of view.

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 during landing before it approaches the runway, and to increase the information content of the vertical runway indicator by introducing the indication of the predicted values of the depression during the runway down and the top when the runway moves up, which allows the pilot to determine the time remaining with him before landing.

The technical result is achieved by the fact that the indicator of true vertical and vertical movement, comprising: a color LED screen with a pixel matrix structure, the following are integrated in the information field: in the upper part of the screen, the information field of the roll indicator, the information field of the direction indicator and the vertical displacement of the runway center with a built-in symbol for displaying the current value of the height of the center of the runway when it moves down and a symbol for indicating the current value of the height of the center of the runway l when it moves up, 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 navigation system, which provides the output of the current values of the onboard parameters, keel and vertical quality, and on the other - to the LED color screen and in the computing unit of which, software and computing modules are integrated: a module for setting the brightness levels of LEDs with a wind screen, a module for generating a symbol for indicating the current position of the center of the runway in height when the runway is moving down and controlling its position in height, a module for generating a symbol for displaying the current position of the center of the runway for height when the runway is moving up and controlling its position in height, the module for forming the on-board indicator scale pitching, the module for calculating the amplitude of the vertical movement of the center of the runway when moving down or up, as well as the screen and the console are connected to power sources, in addition, additionally enter The light bar for orientation of the pilot in space when landing on the ship runway made in the form of a light bar of the true vertical pointer located vertically on the information field of the screen is introduced, and for its formation and control of the angular position, computer-program modules are introduced into the control unit: the indicator light formation module true vertical, a module for converting information from the navigation system into control signals for the angular position of the indicator light bar I of the true vertical, the following are built into the information field of the indicator of the direction and magnitude of the vertical displacement of the center of the runway: a light line to indicate the predicted position of the wave trough included when the center of the runway is down, a light line to indicate the predicted position of the wave tip, included when the center of the runway goes up, to the computing unit software and computing modules are introduced: a module for generating a light line for indicating a predicted value of a wave depression, a module for generating a light line, and indication of the predicted value of the peak of the wave.

In the information field of the screen in its lower part, the information field of the on-board pitch indicator scale and the on-board pitch indicator scale is additionally built-in, and the software and computer module for forming the scale of the on-board pitch indicator is introduced into the control unit.

The indicator consists of a color LED screen 1 and a control panel 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. Remote control 2 and ESC 1 and the remote control and ship navigation system are connected using multiplexed wired communication lines.

When pitching only along the trim, screen 1 and strap 1.1.2 maintain a vertical position, but at the same time, software and computing module 2.1.1.4 of formation and control of the symbol 1.1.3.1 for displaying the current value of the runway center height when moving down and module 2.1.1.4 of formation begin to work and control the light line 1.1.3.4 to indicate the predicted position of the wave trough when the runway is moving down and, accordingly, software and computing module 2.1.1.6 to form and control the symbol 1.1.3.2 to indicate the current value of the height of the center of the runway at izhenii up and module formation 2.1.1.6 and 1.1.3.3 control light line indicating a predicted position at the top of wave motion VPPl up. The position of the lines of the predicted values of the depression and the peak of the wave of displacement of the center of the runway is calculated by special algorithms.

When on-board, longitudinal and vertical pitching, software and computing modules 2.1.1 are connected to work. with the help of which, the position of the center of the runway is determined taking into account the location of the center of the runway on the deck of the ship and the pitching parameters specified by the navigation ship system 3.

When the values of vertical pitching are within the limits allowed for a particular type of helicopter, regardless of the direction of pitching, the indication labels of the vertices 1.1.3.3 and the trough 1.1.3.4 are set at the center of the information field of the vertical displacement indicator 1.1.3. The runway center direction symbols 1.1.3.1 and 1.1.3.2 are turned off.

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

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 IHWP.
