Description

Technical Field

[0001] The utility model relates to the technical field of attitude indicators, in particular to a mechanical attitude instrument simulation device for a flight simulator. Background Technique

[0002] The attitude indicator is used to measure the pitch angle, roll angle and sideslip state of an aircraft, and is mainly widely used on training aircraft. During the flight of an aircraft, the aircraft will make various flight postures and headings. The pilot cannot observe the flight attitude of the aircraft in the cockpit of the aircraft. At this time, it is necessary to look at the attitude indicator. The pilot judges the attitude of the aircraft as left or right, up or down. The working principle of the attitude indicator is a highly rotating gyroscope. No matter how the attitude of the aircraft changes, the fixed-axis property of this gyroscope remains the same in space, so it can display the pitch and tilt angle attitudes of the aircraft. The attitude indicator is the central instrument during instrument flight. In flight weather with poor visibility, losing the attitude indicator, the pilot is extremely likely to get lost in space.

[0003] At present, the attitude indicators on the market are mainly realized through graphic simulation instruments, which cannot intuitively display the true flight attitudes of different levels. In flight trainers, highly simulated aviation instruments help to enhance the realism of simulated flight and improve the user experience. The traditional simulation solution is to use graphic simulation instruments in combination with the appearance of the instruments, that is, to directly display the instrument status through a display, and the pointers of the instruments are all realized by software. Although this method can realize the basic functions of the instruments, there is still a large sensory difference from real instruments, which cannot enhance the realism of simulated flight, but instead affects the pilot's visual senses and causes potential hazards during real flight.
