The utility model relates to aviation technology, namely to helicopter simulators.

A helicopter simulator was selected as a prototype [Russian Federation Patent RU 2230371 C2, 7 C 09 V 9/46]. Helicopter simulator contains:

- a helicopter pilot's cabin, equipped with video cameras, acoustic systems and a set of equipment having an adapter system, the appearance of the elements of which, their relative position repeats the appearance and arrangement of the equipment elements of the helicopter cockpit set;

- a booth visual simulation unit, including a booth display unit and a visual environment generation unit, wherein the booth visual display unit may be a system including projectors and a diorama screen mounted in front of the cockpit;

- a computer system that allows you to simulate regular and abnormal flight modes of a helicopter and equipped with a unit for simulating acoustic noise. At the same time, the computing complex contains a programmable block for modeling flight conditions and operating modes, the software of which is capable of modeling aerodynamics, navigation parameters, operation of the power plant, helicopter units and systems;

- the workplace of the simulator instructor, including a control panel and control tools connected to the computer complex, and equipped with a radio simulation unit. At the instructor’s workstation, video monitors are installed, connected to the cabin’s video cameras.

The simulator may include a unit for simulating acceleration effects, including a platform for installing the cockpit, equipped with a control unit connected to the control and monitoring unit of the simulator.

The prototype allows for the training and training of helicopter crews, simulating the operation of helicopter equipment in regular and special situations, simulating the visual environment depending on weather conditions, time of day and time of year, as well as monitoring the work of the crew.

However, the specified simulator does not provide a workplace for the operator of the external suspension of the helicopter and, as a result, there is no possibility of training and training of the crew to work with the external suspension in regular and emergency situations.

The proposed utility model extends the functionality of the simulator, namely, it allows:

- to train and train the helicopter crew to transport cargo on an external sling, which is one of the most important functions of using helicopters;

- to imitate special situations associated with the transportation of goods on an external sling (dumping, swinging and rotating the cargo, breaking lines (s), etc.), and to form the necessary skills of the crew to counter the unfavorable development of special situations.

The above additional simulator functionality is provided by the fact that the helicopter simulator includes:

- the cockpit of the helicopter equipped with speakers, video cameras, a set of equipment with an adapter system, the appearance of the elements of which and their relative position repeat the appearance and arrangement of the equipment elements of the real cockpit;

- a cockpit simulation unit for pilots;

- a computer complex containing a programmable block for modeling flight conditions, aerodynamics, navigation parameters, operation of a power plant, helicopter units and systems and simulator operating modes, a unit for simulating acoustic noise;

- the instructor’s workstation with a control panel and controls, video monitors connected to the cabin’s video cameras, equipped with a radio simulation module for the helicopter’s crew, according to the proposed utility model, the helicopter’s cargo cabin is additionally equipped with an external operator’s operator’s workstation (simulation unit), a simulation unit the hull environment for the airspace operator, and the program complex includes a programmable unit for modeling the impact of cargo transported on an external load on a helicopter . At the same time, the workplace of the VP operator is equipped with a set of equipment that allows controlling the external suspension, and the operator has the ability to visually observe the load against the underlying surface and make voice communication with the helicopter pilots piloting through the intercom.

For a more accurate visual determination by the operator of the position of the transported cargo, the simulated cabin simulator for the VP operator can form a stereo image on the screen, observed through glasses with polaroid glasses.

The cargo compartment can be mounted on a movable base to simulate acceleration effects.

Figure 1 shows a block diagram of a helicopter crew simulator illustrating the invention.

The simulator includes a cockpit, a cargo compartment, an instructor’s workstation (RMI), cockpit simulations for pilots (“P”) and an airspace operator (“O”), a computer complex connected to all of the above blocks. In addition, the cockpit, the cargo compartment and the instructor’s workplace are equipped with intercoms that provide voice communication between the pilots, the airspace operator and the simulator instructor.

The cockpit is a real cockpit, for example, a Mi-8MTV helicopter, or a specially designed cockpit, the internal dimensions and interior of which are an exact copy of the helicopter cockpit. The cockpit is equipped with a set of equipment with an adapter system for communication with the computer complex. As the equipment, real helicopter cockpit equipment is used, which has been modernized in such a way that allows you to completely simulate its appearance and operation. The controls (control knobs, levers, pedals, etc.) are modernized in such a way that during the training process the pilot must exert the same efforts as when controlling a real helicopter.

The cargo compartment is a part of the cargo compartment of a helicopter, for example, a Mi-8MTV helicopter, or a specially designed compartment, the internal dimensions and interior of which are similar to the cargo compartment of a helicopter, in which the central lock of the helicopter's VP, for example, DG-64, with standard suspension controls. The operator’s workplace is the space near the VP hatch through which the operator observes the transported cargo (to accommodate the operator’s workplace, a part of the cargo compartment between the 5th and Xth frames of the Mi-8MTV helicopter is enough).

The cockpit simulation unit for pilots (“P”) includes a display unit, which is a diorama screen mounted in front of the cockpit with projectors directed at it, which displays the cockpit situation synthesized by the visual environment generation unit, as the crew sees it through the cockpit glazing.

The cabin simulator for the VP operator (“O”) includes a display unit representing a screen located outside the cargo compartment and covering the VP sunroof opening, on which the projected image generated by the visual environment generation unit with the VP elements (central rope, slings, swivel, etc.) against the background of the underlying surface, as the VP operator sees through the hatch.

The instructor’s workplace (RMI) of the simulator includes a control unit for controlling the simulator’s work, video monitors, which show the off-cab environment for both pilots and the airspace operator, an image of the dashboard and the main flight and navigation instruments, information from video cameras installed in the cockpit (and cargo compartment).

The simulator is equipped with a computing system that allows you to simulate regular and special modes of operation of the helicopter and its systems, including the impact on the helicopter of the cargo transported to the VP.

Helicopter crew training on the simulator is as follows. Crew members occupy their jobs: pilots in the cockpit, operator of the airspace in the cargo compartment and prepare for flight in accordance with the requirements of the Flight Manual, for example, the Mi-8MTV helicopter.

The instructor of the simulator with RMI loads a flight task into the computer complex (sets the initial conditions, weather conditions, parameters of the transported cargo and airspace, route and other necessary source data). In accordance with the programs laid down in the computer complex, real-time simulation of the operation of helicopter systems begins, the corresponding parameters are transmitted via an adapter system to simulators of flight and navigation instruments in the cockpit. On the screens, the booth visual environment is reproduced both for pilots and for the airspace operator, as close as possible to the real one. Speakers are included that reproduce the noise of the propeller and helicopter power plants. Radio communication is turned on and the instructor sends commands to the crew similar to those transmitted from the ground-based flight control command center.

Pilots carry out a training flight in accordance with the task, acting on the simulators of the helicopter controls, the signals from which through the adapters enter the computer complex of the simulator and are used to simulate the flight.

The airspace operator through the hatch visually monitors the behavior of the transported cargo and through the intercom gives commands to the pilots to change the flight mode (speed, altitude, course) or to perform operations with the cargo (hitching, lifting, stacking, dumping).

The simulator instructor on his video monitors monitors the progress of the training flight, through the intercom, gives commands to the crew if necessary, changes the flight conditions using the control panel, for example, introduces system failures or changes weather conditions, etc.

In the cockpit there may be an instructor observer who directly controls the actions of the crew. The cockpit and cargo compartment can be mounted on a movable platform to simulate acceleration effects.

All information about the training flight is archived in the computer complex of the simulator for subsequent analysis and analysis of crew actions.

Thus, the simulator allows training the helicopter crew to carry out the transportation of cargo on an external sling in regular and special situations.
