Technical Field

[0002] Flight simulators have developed rapidly due to their outstanding advantages, including safety, reliability, convenience, economy, high efficiency, and unrestricted by weather conditions. Their history dates back to the 1920s. Over the past seventy years, flight simulators have evolved through three stages: mechanical, electronic, and digital. Motion systems have progressed through single, two, three, and finally six degrees of freedom. Control methods have transitioned from mechanical and electronic to digital. Training methods have evolved from manual and mechanical to fully digital computer simulation. Visual systems have evolved from optical transparency and film to the widespread use of closed-circuit television and camera projection, and finally to the most popular computer-simulated reality graphics and imaging technology. Simulated cockpits have evolved from having only partial analog instruments to a complete, synchronized flight instrumentation pod.

[0003] Flight simulators, broadly speaking, can be divided into two categories: engineering research simulators and training simulators. The former are used for researching and testing new aircraft and improving existing ones; the latter are used to train pilots, enabling them to master flight control techniques and related skills such as navigation, bombing, shooting, and air combat, as well as the use of complex equipment. Training flight simulators allow pilots to control the aircraft from the ground, using the same methods as in an actual aircraft, and experience the sensation of flying in the air.

[0074] S1, determine the relative positions and sizes of the frame 3 and the support arms 4 according to the outer dimensions of the dome roof;

[0075] S2, determining the angles of the first positioning card assembly, the second positioning card assembly, and the third positioning card assembly according to the curvature of the dome top cover;

[0076] S3, frame 3 is made of Q2353 steel square tube and standard parts, support arm 4 is made of Q235 steel square tube and standard parts, and various positioning clamps are made of Q235 steel plate and standard parts;

[0077] S4, the support seat 6 is composed of Q235 angle steel, angle iron, positioning pins, connecting plates, etc., which are all standard parts of corresponding specifications.

[0078] The above is only an embodiment of the present invention. Common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme in combination with their own abilities under the guidance of this application. Some typical well-known structures or well-known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention.
