Description

Technical Field

[0002] The horizontal tail servo actuator system of an aircraft is the core component for realizing the change of the pitch direction of the aircraft and is one of the key components for controlling the lift and attitude of the aircraft. Its normal operation is crucial for the flight safety and performance of the aircraft. To ensure the flight safety and reliable performance of the aircraft, it is necessary to regularly inspect the horizontal tail servo actuator system to detect potential problems or faults in a timely manner.

[0003] Carrying out inspections, adjustments, and circuit detections on the horizontal tail servo actuator system helps to detect potential faults early and prevent aircraft accidents caused by faults. Through regular maintenance and inspections, components with problems can be repaired or replaced in a timely manner, improving the reliability and maintenance efficiency of the aircraft.

[0004] However, the inspection work on the actual aircraft requires the aircraft to be parked in the maintenance area and a series of preparatory work such as starting and stopping the engine, which consumes a lot of time. Using actual aircraft and equipment may incur costs such as downtime costs and labor costs. Professional technicians are required for operation and maintenance, and a large amount of time and resources are needed to train these personnel. During the inspection process of the actual aircraft, due to complex operations or technical problems, misoperations or faults may occur, posing risks to the safety of the aircraft and personnel. The inspection work on the actual aircraft involves manual operations and coordination, and a large amount of time and energy are required for communication and cooperation among personnel.

[0005] Based on the need for training in the inspection work of the aircraft horizontal tail actuator system and to solve the problems of long preparation time, high cost consumption, and high safety requirements in the inspection work of the actual aircraft, it is urgent to develop a simulation training device.
