Description

Technical Field

[0001] This utility model belongs to the field of mechanical structure design, specifically relating to an altimeter simulation device for a helicopter flight simulator. Background Technology

[0002] Helicopter altimeters, typically located in the helicopter cockpit instrument panel, display the vertical distance of the helicopter from a horizontal reference plane, transmitting this information to the pilot as a visual signal. Flight simulators, being ground-based equipment, do not produce actual altitude changes; however, to enhance the pilot's immersion, the helicopter's instruments need to be replicated one-to-one, maintaining a display effect consistent with the real aircraft.

[0003] However, existing helicopter flight simulators do not require precise control of their altimeter devices, resulting in poor control accuracy and stability, and reducing the pilot's immersion. Summary of the Invention
