Description

The utility model relates to aviation technology and can be used to create helicopter simulators with a hinged rotor to instill the initial skills of piloting a helicopter, training the crew to simulate the operation of helicopter equipment in standard and special situations, in particular in helicopter simulator devices with a hinged rotor, as well as in simulators for cultural entertainment.

Known integrated simulator helicopter MI-8 (patent RU No. 2061257, IPC G09B 9/46, publ. 05.27.1996), containing a cabin in internal geometric dimensions, composition and placement of equipment is fully consistent with the cabin of the helicopter Mi-8, 98 series and equipment was installed in the form of a complex of electronic and electromechanical devices of an analog type, externally subjected to modernization, allowing devices to simulate the operation of real equipment, and a calculator, in the form of a single unit based on electronic devices and electromechanical equipment Ia, the calculator simulator consists of acoustic noise, visual conditions, power conditions, flight instruments, flight dynamics, systems and equipment of the helicopter, over et al., as well as embedded control system. The acoustic noise simulator is connected to the speakers installed in the cab, and the visual environment simulator is connected to the monitors. The instructor’s workplace provides the ability to control and train pilots and is equipped with control instruments for the aerobatic group and engine operation, a flap for selecting flight conditions and entering the selection of failure models, as well as an alarm system, and the cockpit is mounted on a movable base.

A disadvantage of the known technical solution of the specified simulator is the large size, which is due to the presence of a large amount of hardware to ensure its operation. The consequence of this is the complete lack of mobility of such an integrated simulator. This does not allow for training (retraining) or restoration of the skill of piloting pilots in the field of operation of helicopter equipment.

The closest in technical essence to the claimed utility model and taken as a prototype is a helicopter simulator (patent RU No. 2230371, IPC G09B 9/46, published June 10, 2004) containing a helicopter cockpit equipped with video cameras, speakers, a set equipment, the appearance of the elements of which, their relative position repeats the appearance and arrangement of the equipment elements of the cockpit kit of a particular helicopter, a simulated cockpit visual unit, and a display unit of a cockpit visa The actual situation may be a system that includes projectors and a diorama screen installed in front of the cockpit, a computer system that allows you to simulate regular and abnormal flight modes of a helicopter.

At the instructor’s workstation, video monitors are installed, connected to the cabin’s video cameras.

A disadvantage of the known technical solution is the design complexity, which consists in large overall dimensions and, accordingly, the large number of hardware (technical) support for functioning, which reduces reliability and mobility for restructuring another helicopter on the model, as well as the inability to simulate the flight characteristics of a helicopter equipped with a jointless rotor , reducing the accuracy, and in general, the effectiveness of the flight stand of the helicopter (simulator) for training and training crew.

The technical problem of the claimed utility model is the creation of an effective flight stand (simulator) of the helicopter to instill the initial skills of piloting, training the crew by simplifying the design by increasing reliability, mobility, accessibility, and accuracy of simulating flight characteristics.

The technical result is achieved by the fact that in the aerobatic stand of a helicopter with a hingeless rotor containing a control unit, which is a frame structure with a pilot's seat fixed to it and power controls located in full accordance with the ergonomics of the helicopter cockpit, a control unit for the cockpit visual environment, a computer complex simulating regular and abnormal modes of operation of a helicopter and equipped with a block for simulating acoustic noise, containing a programmable block model of flight dynamics and modes, connected to the control unit, the instructor's workplace includes control means connected to the computer complex, according to which the computer system is based on the input of one main computer with software for visualizing the cockpit space in various climatic and meteorological conditions, simulating acoustic noise , as well as simulations of the operation of helicopter assemblies and the flight and navigation instrument panel, with an additional monitor and the instrument panel was introduced with the possibility of simulating any existing type of helicopter, without changing the hardware, and an additional laptop computer was introduced as the instructor’s workplace, cyclic step control knobs and power steering controls rotor pitch pedals are equipped with spring loading mechanisms configured to the impact of the effort on the controls proportional to their movements, the visualization system monitor is introduced into the control unit of the cabin visual environment e concave screen to convey the depth of space and the feeling of being in the current technique, in addition, the monitor of the visualization system is located next to the input speakers that simulate the noise of helicopter screws, while enhancing the real effect of being in the current technique.

computer; surge protector - SF; UPS is an uninterruptible power supply.

The flight stand contains the main computer 1 of the flight stand, which is recommended to be installed behind the pilot's back (not strictly regulated). The concave monitor of the visualization system 2 is installed at such a distance that the viewing angle allows you to "capture" the picture from the screen completely. Only in this case, the side points located at the edges of the right and left parts of the screen, as well as the central point between them, will have an equal distance from the viewer's eyes. In this case, the only true position of the viewer will be exactly in the middle of the TV (monitor), so that the viewing angle allows you to "capture" the picture from the screen completely. The imaging system monitor 2 connects to the host computer using an HDMI cable. The dashboard simulation monitor 3 is located directly in front of the pilot of the stand. Monitor 3 is connected to the host computer via a VGA cable. The monitor is powered by an uninterruptible power supply.

The pilot seat 10, the cyclic step control knob 5, the general step 6 control knob, the engine control knobs 7, the tail rotor 8 pedals, the rotor 9 friction brake are located on the fastening frame 4 in full accordance with the ergonomics of the helicopter cockpit. Controllers (KUs) that digitize the movements of knobs and pedals are connected to the host computer using a USB cable. An additional control system computer (KUS) control (laptop) can be located anywhere and is connected to the host computer with an Ethernet cable. Audio speakers 11 are also connected to the host computer using an AUX cable. Inside the frame 4, control controllers are installed. On the handles are installed simulators of spring force. The efforts made to change the position of the knobs and control pedals vary linearly (spring effect), but there is no feedback. In the absence of impact from the pilot’s side, the control knobs of general 6 and the rotational steps 5 of the rotor (HB), as well as the pedals of step 8 of the tail rotor (PB) are in the neutral position. When extreme positions are reached, the efforts on these power control bodies reach their maximum values. The general control knobs 6 have position locks. The engine control knobs 7 do not provide additional power resistance to their movement (have position locks).

Training flights are as follows.

The pilot (at the stand) and the instructor occupy their jobs. The instructor loads one of the tasks: sets the coordinates of the departure point, time of year and day, weather conditions, helicopter loading data and other necessary source data. On the concave monitor of the visualization system 2, an indented visual environment is reproduced. The pilot or instructor launches the power plant. In this case, the acoustic speakers 11 emit the noise of spinning screws. On the monitor screen of the visualization system 2, the rotation of the propellers as well as dust clouds arising due to the inductive flux created by the rotor of the helicopter are displayed.

A training flight is carried out by the pilot by influencing the power controls 5,6,7, 8, 9 of the aerobatic stand. Through a system of controllers (KU), the digitized signal is transmitted to the computer complex of the main computer with software simulating the dynamics of flight of a helicopter with a hingeless screw, which calculates the trajectory of the helicopter displacement from the course set by the instructor for the current period of time. Data on the movement of the helicopter is transmitted to the visualization system 2 of the cockpit space and displayed on the concave monitor 2 (Fig 3).

During training flights, the crew, independently or at the instruction of the instructor, changes the navigation parameters that are displayed on the additional simulation monitor of the dashboard 3 of the navigation system: course, speed, altitude, location coordinates. The instructor changes the external conditions (time of day, visibility, etc.), and the crew must complete a training flight. Thus, the work of the aerobatic bench allows for training flights.

The proposed utility model of a helicopter flight bench with a hinged rotor, in terms of its technical and economic advantages compared to its known analogues, is due to its rational design solution by simplifying the design by increasing the reliability, mobility and accuracy of simulating flight characteristics, i.e. creating an effective stand (simulator) of a helicopter with a hingeless screw allows you to provide high-quality inculcation of the initial skills of piloting a helicopter, training pilots. At the same time, it has small dimensions, low cost and power consumed by it, which is achieved through the use of virtually only one personal computer and the rational layout of the inventive flight bench.
