[0031] Embodiment 2:

[0032] The present invention realizes the simulation of a lightweight flight skill enhancement training cabin by constructing the bottom structure of the cockpit, the layout of the equipment in the cabin, the equipment installation interface, the wiring space, etc. The hardware skeleton simulates the size and layout of the aircraft cockpit, including the cabin structure, the layout of the equipment in the cabin, the equipment installation interface, the wiring space, etc. The hardware skeleton subsystem is the installation basis of the cockpit electrical equipment, display and control equipment, the operating mechanism, etc. The cockpit adopts interior and exterior design, and the interior is basically the same as that of the teaching aircraft. The exterior has ornamental and "military" properties, and adopts fiberglass composite materials to reduce the weight of the system and improve convenience.

[0033] The hardware skeleton mainly includes: cockpit bottom bracket, cockpit floor, simulated seats, left and right control consoles, instrument panel, display bracket, wiring trough, equipment box, etc.

[0034] (1) Cockpit bottom bracket

[0035] The bottom bracket of the cockpit includes the bottom universal wheels, support frame and floor, which can support the weight of the cockpit and trainees;

[0036] There are no protrusions around, and the edges are rounded, so it will not cause harm to the human body if accidentally touched;

[0037] The bottom bracket is equipped with 6 universal wheels, which are durable and easy to move;

[0038] The bottom bracket must be securely fixed to the ground, and the cockpit must not move when people enter and exit the cockpit environment or perform technical flight maneuvers in the cockpit;

[0039] While ensuring structural strength, the bottom bracket should be hollowed out appropriately to reduce weight and improve the appearance.

[0040] Equipment material: The front end of the equipment is made of fiberglass, which has a smooth and beautiful shape; the overall frame is made of aluminum profiles, which can greatly reduce the weight of the frame; the front panel and the left and right control consoles are made of 0.8mm lightweight aluminum panels; the seat surface, backrest and structure are made of 304 stainless steel metal; the structure is sturdy and durable, and the paint will not fall off.

[0041] Entering and exiting the cockpit: Considering that the left console simulates hardware equipment, but the right console does not, people enter and exit from the right console, and the bottom bracket has an appropriate height to facilitate people entering and exiting the cockpit.

[0042] Cockpit color: The interior of the cockpit and the left and right control consoles are gray, the front dashboard is gray-black, which is basically the same as the real aircraft, and the exterior of the cockpit is mainly blue.

[0043] (2) Cockpit floor

[0044] The cockpit floor is the installation base for the entire cabin equipment. The floor is made of 7075 aviation aluminum profile laser cutting, which not only meets the shape and strength requirements of the entire floor, but also reduces the weight of the whole machine to meet the lightweight design requirements.

[0045] (3) Simulation seat

[0046] Simulate the shape, structure and safety harness of the pilot's seat to provide users with a realistic cockpit environment and driving experience;

[0047] The seats are designed and manufactured with weight reduction in mind;

[0048] The ride is comfortable and it is convenient for trainees to operate the equipment.

[0049] (4) Left and right control panels

[0050] The design of the left and right control consoles makes it easy for trainees to see, touch and operate;

[0051] The left and right control panels have the same structural dimensions as the CJ-6 aircraft and are installed in blocks independently, that is, they are separated from the bottom frame and support independent disassembly.

[0052] The left and right control consoles are made of 0.8mm lightweight aluminum veneer material, with metal frame support inside. Hollowing is used appropriately to reduce weight, which can reduce weight to the greatest extent and improve appearance without affecting structural strength.

[0053] The left control panel can securely fix the equipment in the cabin. It is equipped with pitch handle, throttle handle, altitude adjustment handle, handle tension handle, flap control handle, and fire switch handle. There are no other hardware equipment. The panel and equipment will not shake during operation.

[0054] The table height and relative position of the left and right control panels are consistent with those of the CJ-6 aircraft;

[0055] The left and right knee guards and the front control panel of the cockpit are plate structures, and other places can use tube beam structures;

[0056] The right-side control panel takes into account the convenience of entering and exiting the cockpit and meets the requirements of lightweight design.

[0057] (5) Instrument panel and display bracket

[0058] A display bracket is reserved at the front of the cockpit for installing a fixed display, which displays the virtual main instruments, indicators, switches, and buttons in the middle area of ​​the front dashboard;

[0059] The instrument panel is the installation platform for the magneto switch, landing gear handle, and various switches. The instrument panel and its landing gear retracting and extending handle and its left latch, instrument panel switch, start button, and magneto switch are all fixed on the upright mounting bracket in front of the cabin. The left and right sides of the bracket are fixed to the cockpit base, and the left side is fixed to the left control panel to ensure stability during use and prevent shaking when actually operating the equipment on it.

[0060] The dashboard is made of fiberglass, which reduces the use of large areas of metal and reduces the weight of the cabin.

[0061] Some of the physical equipment in the cabin are real, and some are displayed in the virtual vision. It is mainly composed of the joystick assembly, throttle assembly, pedal assembly, landing gear handle, flap handle, fire switch handle assembly, 14 electric switch assemblies under the dashboard, start button, magneto switch, etc.

[0062] Sensors are installed on the equipment in the cabin, which can output the position information of the control stick, throttle lever, pitch lever, altitude lever, pedals, etc. and the gear information of the switch button. The movement hinge point and movement stroke of the control stick and pedals are consistent with those of the real aircraft, and there are appropriate force springs to simulate the control force. The movement stroke of the throttle lever, pitch lever and altitude lever handle is consistent with that of the real aircraft and has adjustable damping characteristics.

[0063] In summary, by constructing a lightweight cabin composed of the above-mentioned hardware skeleton and cabin equipment, the requirements for conducting virtual and real combined flight skill enhancement training can be met.

[0064] In order to improve the teaching effect of reading and using the equipment in the cabin, complete the training tasks, and take into account the needs of personnel entering and exiting the cockpit, some equipment is displayed in real objects, and some equipment is displayed in virtual scenes. The control equipment with high operation frequency and importance is displayed in real objects, and the equipment or control buttons that do not need to be operated or have low operation frequency and low importance are displayed in virtual scenes.

[0065] Division principle: Considering that the cabin is designed based on the primary trainer aircraft and is used for primary training, and does not involve special situation training, virtual devices are used for switches used for special situation training. In addition, various instruments and switches on the dashboard and console are low-cost, and the use of physical equipment is less effective in increasing pilots' flight skills, so virtual devices are used.

[0066]

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should all be covered within the protection scope of the present invention.
