Description

Technical Field

[0001] The invention relates to the technical field of flight simulation, and in particular to a modular roll-on / roll-off platform and a cabin changing method for a level D flight simulator. Background Art

[0002] Flight simulators are indispensable tools in the flight training and certification process. They can safely simulate the flight status, flight conditions and environment of an aircraft on the ground. Among them, Class D flight simulators have become the preferred equipment for professional flight training because they provide advanced dynamic and visual simulations. Class D flight simulators can accurately simulate the cockpit environment of the aircraft model, including realistic simulation of the flight cockpit, simulated instruments, displays, indicators, control lights, switches, buttons, circuit breakers and control devices. The appearance, installation location, signage and functions of these components are consistent with the real aircraft, ensuring the realism and effectiveness of flight training.

[0003] However, the existing flight simulator technology has several significant disadvantages: First, the cost of building a new Class D flight simulator is extremely high, mainly because it requires a dedicated operating site and a dedicated simulated flight cockpit customized for a specific aircraft model. This "one aircraft, one cabin" model not only leads to high initial investment and operating costs, but also makes the maintenance of the dedicated simulated flight cockpit complicated and expensive, especially when replacing parts or upgrading, which is time-consuming and labor-intensive, and will cause the simulator to be out of service for a long time, affecting the continuity and efficiency of training. Secondly, traditional flight simulators have low flexibility. Since each aircraft model requires a dedicated simulated flight cockpit, the equipment utilization rate is not high, and it is difficult to meet the diverse training needs. This design limits the application of simulators in training of different types of aircraft, increases operating costs and management difficulties, and at the same time, the customization and maintenance of each simulated flight cockpit requires a lot of resources, further exacerbating cost pressure and management burden, and it is difficult to achieve the optimal allocation of resources. Some existing solutions try to improve flexibility by sharing simulated flight cockpits or using multi-functional cockpits, but these methods usually bring new problems, such as interface incompatibility, long conversion time, complex operation and additional adaptation costs, and fail to fundamentally solve the problem.

[0016] 1. In order to solve the problem that the maintenance of existing dedicated simulated flight cockpits is complicated and expensive, especially when replacing parts or upgrading, it is time-consuming and labor-intensive, and will cause the simulator to be out of service for a long time, affecting the continuity and efficiency of training. Secondly, the flexibility of traditional flight simulators is low. Since each aircraft model requires a dedicated simulated flight cockpit, the equipment utilization rate is not high and it is difficult to meet the diverse training needs. The present invention significantly shortens the cockpit change time of the D-level flight simulator through an automated slide rail system and a roller retracting and extending mechanism. According to the embodiment, the total time for changing the cockpit can be reduced from the traditional multiple hours to no more than three hours, greatly improving the availability of the training equipment. At the same time, due to the modular design, when changing the cockpit, the overall frame and shell of the D-level flight simulator No disassembly is required, which avoids possible operational errors during cabin change. The modular design and central control system simplify the steps of cabin change operation. The operator initiates the cabin change command through the touch screen interface, and the system automatically performs most of the physical operations, reducing the complexity of the operation and the possibility of human operation errors. The automatic positioning and locking devices ensure that each module is accurately aligned and fixed during the cabin change process, avoiding possible errors in manual operation. The universal design of the base frame and slide rail system enables a flight simulator platform to adapt to different training needs, increasing the applicability and flexibility of the equipment. Due to the ease of operation and shortened time, the dependence on highly skilled operators is reduced, thereby reducing long-term labor costs.

[0017] 2. In order to solve the problem that customization and maintenance of each simulated flight cockpit require a lot of resources, further aggravating cost pressure and management burden, making it difficult to achieve optimal resource allocation, some existing solutions attempt to improve flexibility by sharing simulated flight cockpits or using multi-functional cockpits, but these methods usually bring new problems, such as interface incompatibility, long conversion time, complex operation and additional adaptation costs. The present invention ensures that each module is accurately aligned and fixed during the cabin change process through automatic positioning and locking devices, avoiding possible errors in manual operation. In addition, multiple safety inspection mechanisms further ensure safety during operation.

[0018] 3. The present invention also reduces maintenance costs and improves the economic benefits of the overall system through modular design and rapid replacement of wearing parts; all key components have undergone anti-corrosion treatment and environmental adaptability design to ensure stability and durability under different climates and usage conditions. The system design allows adaptation to possible deformation, wear or expansion due to temperature changes, ensuring the reliability of the system in long-term operation.
