Description

The onboard helicopter automatic return system (BSAVV return system) is designed to automatically return the helicopter to the base, reserve site in the event of a partial, long-term and complete loss of crew performance.

The BSAVV return system is applicable to helicopters of any type of military and civil use, operated in all possible regions and equipped with modern navigation and aerobatic, communications equipment, performing automatic flights along a given route and landing at a selected location.

The return of the helicopter without crew participation allows you to save the helicopter for subsequent operation, save passengers and valuable cargo, and reduce the costs of a search and rescue operation.

Known methods for the automated return of manned aircraft to airfields with crew participation that manually switch the aircraft into automatic flight mode along the route selected by the crew and reverse switch over implement manual landing control. The system functions while maintaining the full working capacity of the pilot in flight.

Improving flight safety in the event of a pilot's loss of operability by automatically switching to a change in flight mode until the pilot is restored to operability is implemented

in the on-board active flight safety system BASBP, which is the prototype for the proposed utility model (On-board active flight safety system. (Utility model certificate No. 22256 of 03/10/2002).

BASBP includes equipment for monitoring the status of the crew, a unit for assessing the state of on-board systems, a manual control and display panel connected to an analysis and control unit for automatically changing the flight mode, to which is connected a block for programmatically changing the flight mode (altitude reduction, overload) associated with the autopilot.

After restoration of the pilot’s performance, the automatic mode is canceled.

The described system helps to restore the pilot’s performance, but does not perform the tasks of automatic return and landing. The automatic return and landing of an aircraft on the runways of aerodromes, especially with heavy air traffic, creates certain technical and organizational difficulties.

Helicopters, unlike airplanes, can land on limited and unequipped platforms in the vertical descent mode, which creates the prerequisites for the complete automation of the helicopter return and rescue mode without crew participation.

The technical task of the claimed utility model is the elimination of the above limitations and disadvantages, namely the lack of automatic return of the helicopter from the moment of fixation

loss of crew performance before helicopter landing on the selected site.

The technical result is ensured by the fact that the on-board system for automatic return of the helicopter consists of equipment for monitoring the condition of the crew, a unit for assessing the status of on-board systems, a manual control and display panel connected to an analysis and control unit for automatically changing the flight mode, the output of which is connected to the site and route selection unit automatic return, to which the navigation unit is connected and the first output of which is connected to the emergency message generation unit With data exchange equipment, the second output is connected to the unloading control unit associated with the cargo separation equipment, and the third output of which is connected to the autopilot of the helicopter, which implements automatic flight along the chosen route and landing on the platform.

The utility model is illustrated in the drawing, where Fig. 1 shows a block diagram of an on-board helicopter automatic return system.

The onboard system for automatic return of the helicopter includes equipment for monitoring the status of the crew 1, a manual control and display panel 2 connected to an analysis and control unit for automatically changing the flight mode 3, to which a unit for assessing the state of the onboard systems 4 is connected, and an analysis and control unit for automatically changing the flight mode 3 is connected to the site selection unit and the automatic return route 5, to which the navigation unit is connected

situation 6 and the first output of which is connected to the emergency message generating unit 7, connected to the data exchange equipment 8, the second output is connected to the unloading control unit 9, connected to the cargo separation equipment 10, and the third output of which is connected to the autopilot of the helicopter 11.

The operation of the claimed utility model "On-board automatic return of the helicopter" (BSAVV) is as follows:

The equipment for monitoring the state of crew 1 continuously in flight performs monitoring and diagnostics of the status of the crew, determines the moment the crew loses its working capacity, which is reported to the analysis and control unit for automatically changing flight mode 3.

The remote control and indication 2 is intended for manual activation of the automatic return mode, if the crew themselves state their inoperability. Disabling the automatic return mode is also carried out using the remote control by the crew after restoring its performance.

The unit for analysis and control of automatic change of flight mode 3 analyzes information from the equipment for monitoring the status of the crew 1, from the remote control and display 2, as well as from the unit for assessing the state of on-board systems 4, which evaluates the state of on-board systems of the helicopter involved in the automatic return and landing of the helicopter .

The decision made by block 3 on the automatic return of the helicopter is sent to the block for selecting the site and route for automatic return 5, which, based on the data from the block of navigational conditions, taking into account the information from the unit for assessing the state of the on-board systems 4, selects an acceptable landing site and a safe route to achieve it.

Unit 5 sends the results of site selection and return route to the unit for generating an alarm message 7, which comes from unit 7 to the data exchange equipment 8, if necessary, is encoded and transmitted for emergency and rescue services. The second output of block 5 is connected to the unloading control block 9, which in a predetermined place through the cargo separation equipment 10 discharges dangerous and difficult to land cargoes. The third output of block 5 is connected to the autopilot of the helicopter 11, which automatically ensures flight along the route set by block 5 and the helicopter automatically lands on the selected site.

The on-board automatic helicopter return system performs a series of operations to determine the moment the crew lost operability, assess the state of the helicopter's on-board systems, make a decision on automatic return, choose a site and return route, unload the helicopter before landing, notify rescue services and ensure automatic return and landing, completely replacing the lost crew.

The state of the crew is determined in block 1 by the set of deviations from the norm in the actions of the crew to control the helicopter, changes in the medical and biological parameters of the body, detected by contact and non-contact sensors, according to the reaction to test signals. An integrated assessment of all indicators in a timely and reliable manner establishes the fact that the crew lost working capacity.

In a complex analysis and decision is made in block 3 on the transition to the automatic return of the helicopter according to information about the crew’s condition and the state of the on-board systems, about the presence of dangerous and difficult landing cargoes, which allows not to aggravate the emergency and safely and automatically bring and land the helicopter.

The navigational calculation is automatically performed by the site selection block and the automatic return route 5, taking into account the fuel supply, options for possible landing sites having different levels of medical and technical assistance, and the availability of helicopter preliminary unloading sites. The route is formed in accordance with the data on the terrain, dangerous and prohibited flight areas, which are contained in the navigation unit 6.

The emergency message generation unit 7 combines information about the place, time and nature of the crew crisis, the selected site and route, the estimated time of return, which directs emergency services to operational assistance at the helicopter landing site. The message is transmitted through communication equipment 8.

The unloading control unit 9 at the location designated by the unit 5 when approaching the landing site issues commands to the cargo separation equipment 10, which ensures discharge of cargo, landing safety and the possibility of further transportation of cargo by other means.

On the route set by block 5, the autopilot of the helicopter 11 implements automatic flight and landing at the landing site, followed by shutdown of all on-board systems, while maintaining the helicopter's readiness for subsequent evacuation.

The onboard helicopter emergency return system in the inventive composition has small mass-dimensional parameters and energy consumption, meets the standards for pairing and information exchange in modern on-board equipment complexes, which makes it easy to integrate the BSAVV return system in new or upgraded on-board electronic helicopter complexes.

As the crew monitoring equipment, any diagnostic equipment certified for helicopter systems is applicable.

The BSAVV return system gives new qualities to helicopter complexes:

- preservation of a functioning helicopter with an inoperative crew for further flight operation;

- the ability to provide emergency medical assistance to the crew after the return and landing of the helicopter;

- the exception of the destruction of ground objects and the death of the population accompanying the fall of an uncontrolled helicopter;

- rescue of passengers, valuable goods and their subsequent evacuation from the landing site;

- preventing the capture of the helicopter and its systems by opposing systems;

- reducing the cost of the search and rescue operation in the search for a search at a specified touchdown point;

- evacuation of the helicopter to the main base by a shift crew.
