Abstract: In order to improve the effect of visual display system in helicopter simulator system, and to enhanc the installation and maintenance of equipment, the method is based on x-type side-cabin helicopter, studying from optical design, dome design, projection support and shelter design, geometry correction and edge blending design. Research was discussed from a theoretical analysis of optical design method, taking fully into account the practicality and versatility of the structure of the dome design, integrated projectors support and shade structures, as well as the unique geometric correction method of geometric reference system. This method was validated by actual project application, on the premise of meeting the various technical indicators, depending on the design, transport of structure is easy to install and easy to maintain, focusing on practical application of visual solution.

Key words: helicopter flight simulator, optical design, projection support and shelter structure, geometric reference system
