直升机飞行模拟器视景显示系统的研究

Research on Visual Display System of Helicopter Flight Simulator

为提高视景显示系统在直升机模拟器中的显示效果,增强设备的可安装性和维护性,此系统以某型并座式座舱直升机有研究对象,从光路设计、球幕设计、投影器支持和遮挡结构设计、几何校正和边缘融合设计进行深入分析。研究论述了从理论上分析论证的光路设计方法,充分考虑到结构的实用性和通用性的球幕设计方法,一体化设计的投影器支撑和遮挡结构,以及具有独特几何参考系统的几何校正实现方法。此研究方法经过实际项目应用验证,在满足各项技术指标的前提下,视场设计合理,结构便于安装运输,设备便于维护,是一套侧重于实际应用的视景解决方案。

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.
