Description

The invention relates to methods for monitoring and fixing flight parameters of an airplane or helicopter. What is necessary for the case of a subsequent analysis of flight conditions, the nature of piloting, crew actions and instrument readings.

From the technical literature, there is a known method for monitoring and fixing flight parameters with an on-board storage device (the so-called “black box”), which is protected and fixed on board the aircraft (see “Encyclopedia of Aviation”, p. 118, ed. “TSB” and TsAGI, 1994 ) This method provides registration of flight information - parametric and speech. Parameters are recorded on magnetic or metal tape. That ensures the safety of information when exposed to high temperatures, shock loads, aggressive fluids, etc. This information is used by emergency commissions when investigating flight accidents.

Such a control method and an information recording device does not provide instant monitoring and data recording at the current time by the ground recorder and information storage not on board a flying aircraft, but at the ground control point of flights.

In addition, there is a known method and device for monitoring national economic objects using unmanned aerial vehicles (UAVs), see “Collection of reports,” IX International Scientific Conference on Hydro-Aviation. "Gidroaviasalon-2012", M., TsAGI, 2012, p.77-97.

This device has a television camera and a number of measuring devices installed on the UAV (unmanned aircraft, helicopter, aerostat). Here, the video image and instrument data are transmitted to the command center using radio transmitters with dedicated radio frequencies. Such a device for transmitting information has a complex structure, low operational adaptability and reliability.

The known device for transmitting television images and instrument readings does not use standard communication systems.

Therefore, a minimum amount of information is transmitted from a remotely piloted aircraft (UAV) to a ground-based recorder. This method and device for its implementation does not transmit sound information, the situation on board the aircraft and the environment.

The closest technical solution corresponding to the invention is the application for the invention of the Russian Federation No. 2141734, class. H04M 9/00, which describes a device for recording and storing information with its subsequent operational use. This device does not provide continuous monitoring of information data and measured parameters. Such a device is complex, it cannot be used to transmit signals from a multi-channel information source, for example, from the dashboard of an airplane. In addition, this device does not provide simultaneous transmission of information from voice informants and multiple information displays.

The technical task of the invention is the transmission in flight of visual information from the displays and dials of the instrument panel of the aircraft, as well as voice information of crew members and the situation in the cockpit, the position of command and control controls, switches and actions of the crew by the ground recorder during the entire flight.

The solution to the technical problem is ensured by the fact that in the cockpit on the on-board holder the smartphone is rigidly mounted so that its lens provides the image of the dashboard and the position of the command and control organs of the aircraft on the smartphone screen, as well as the position and action of the pilots, in addition, for recording voice crew information using smartphone microphones. At the same time, the smartphone’s video and audio signals are transmitted via satellite, remote communication to a ground-based recorder, where video and audio recordings of flight parameters from take-off to aircraft landing are performed, then video and audio recordings of the ground-based recorder are used for technical analysis of flight results in case of emergency or aircraft search during extra-aerodrome landing, as well as its disappearance from the radar screens of the ground-based air traffic control service.

The proposed method is illustrated by the following images and drawings.

Figure 1 is a diagram of the implementation of the method of monitoring flight parameters. Shows the cockpit of a transport aircraft with a smartphone installed on it on the side holder.

Figure 2 shows the on-board holder and the mounting device on it of a smartphone.

Figure 3 shows the installation of a smartphone in the cockpit of the aircraft Sud-Aviasien "Caravel".

Figure 4 shows the installation of a smartphone in the cockpit of the aircraft MS-21

Figure 5 shows the block of the ground recorder and the control panel of an air traffic controller (civilian aircraft) or flight manager (military aircraft, helicopter).

The method of monitoring flight parameters by a ground recorder is as follows.

In the cockpit 1 of the transport aircraft pilots (as shown in FIG. 1), a smartphone 2 is installed, located in the cassette 3, which is fastened with a hinge 4 to the on-board holder 5. The on-board holder is made in the form of a telescopic rack 6, at the end of which there is a flange 7 Flange 7 serves for fastening the holder to the power set 8 of the fuselage of the aircraft 9.

On the ceiling of the cockpit in the area of frames or stringers, the holder is mounted using a flange 7 so that the lens 10 of the smartphone provides a complete view of the instrument panel 11 of the pilots, command and control bodies 12, the helm 13, pedals 14 and provides a general overview of the working area of the cockpit that provides a given viewing angle (<α) of the lens of the smartphone (as shown in figure 1).

Examples of installation of the onboard holder 5 in the cockpit are shown in figure 3 and figure 4.

To fix the reliable and rigid installation of the smartphone 2 in the cassette 3 on the on-board holder 5 on the cassette mounted latches 15. In addition, the latch 16 is also located on the hinge 4 of the cassette. And the telescopic rack 6 of the side holder has a latch 17, which provides reliable fixation of the specified length of the telescopic rack - and the angle of rotation of the cartridge along the axis of the telescopic rack. The cassette has clamps 18 for fixing smartphone 2 in it.

The hinge 4 of the cartridge is detachable, which provides installation on the on-board holder 5 of cartridges of various sizes. Cartridges can have various width, height and thickness. This allows you to use on the on-board holder and in the proposed method for monitoring flight parameters smartphones, iPhones and tablets of various manufacturers.

As you know, the firms Samsung, Apple, Nokia, etc., produce mobile phones, smartphones, iPhones and tablets of various sizes. Therefore, for each mobile recorder sensor (of the types indicated above), an individual cartridge 3 with a standard hinge 4 is required to quickly mount it on the on-board holder 5. Smartphone 2 transmits video through a cellular operator (on local airlines) or via satellite communications on medium-haul and long-haul planes - and audio signals to the ground-based recorder 19 control the flight parameters and its drive 20 information.

The ground-based recorder 19 has a smartphone (iPhone) (not shown) that receives audio and video signals from the aircraft's on-board smartphone 2, which are recorded by the information storage device 20.

The information storage device consists of a recording unit (not shown) of audio and video signals from the aircraft from the onboard smart 2.

The signal from smartphone 2 can be transmitted to the ground-based control recorder and its information storage device via long-distance (if necessary, international) telephone communication. In addition, for the transmission of audio and video signals from an airplane, it can be transmitted via the Internet (via Skype).

Before takeoff, the smartphone is connected to the ground recorder and the flight parameters are recorded by it from takeoff to landing of the aircraft.

If necessary, the dispatcher (or flight manager) can display this information on screen 21, as well as on the headphones (or loudspeaker).

The method of controlling flight parameters is as follows.

Before takeoff, a crew member checks the image of the cockpit and controls on the screen of smartphone 2, for which it turns on the smartphone and dials the smartphone (iPhone) number of the ground recorder 19 and makes its call. After that, video and audio recording of signals from the cockpit is automatically recorded on the ground recorder in the process of preparing the crew for take-off, taxiing the aircraft to the executive start, during take-off, as well as the entire flight before landing and taxiing the aircraft to the parking lot. This is done from a smartphone (iPhone) installed in the cockpit. Audio and video information from the cockpit is constantly recorded by the ground recorder.

The dispatcher (flight director in the Air Force) at any time in the above period of time (except for automatic recording of information) can display on his screen 21 and his headphones or radio information from the cockpit of the aircraft.

In the classic layout of the instrument panel 11 of the aircraft (Fig. 4), for example, the “Caravel” aircraft, the dispatcher sees on the screen indications of flight, navigation instruments for monitoring engine operation, the position of command and control bodies, etc. Recently, such an instrument panel on older aircraft has been additionally equipped with a display - a GPS-global navigation system.

Recently created aircraft have a display dashboard (the so-called "glass cabin"). Such a cockpit is shown in figure 5, here the GPS display is mounted directly in the dashboard of the "glass cockpit".

The presence of a GPS display allows you to know at any time of the flight not only the true altitude and speed of flight (these data are displayed on the GPS screen), but also the coordinates of the aircraft above the Earth’s surface at a given time. In the event of an accident, this reduces the search time for the aircraft.

Recording GPS data allows you to instantly determine the coordinates of the aircraft above the Earth or above the water surface (ocean, sea, etc.) in the event of an accident or extreme landing.

After the flight of the aircraft after 24 hours, the recording of information on the ground recorder is automatically erased.

In the event of special cases of flight during their investigation, the information from the ground-based recorder is used in conjunction with the information on-board and “black boxes”.

Compared with existing methods of monitoring flight parameters by on-board drives - “black boxes”, the proposed invention provides instant monitoring of flight parameters by a ground-based recorder, and at the current moment of flight time.

The proposed method requires minimal financial costs for its implementation. It is provided by simple and reliable devices that are commercially available. They have a small mass and cost.

The proposed method is easy to operate. It provides the ability to search for an emergency aircraft in the shortest amount of time.

When using the proposed method for monitoring flight parameters, the search time for an emergency aircraft and the search for "black boxes" is reduced. Consequently, the cost of rescue work is reduced.

The proposed method improves the safety of flights of civilian aircraft, as well as aircraft, helicopters and gyroplanes of other departments.
