英国航宇公司用了象早先单球顶空战模拟设备的基本原理,根据以前的经验及开发模拟器训练潜力的要求,决定作几种改进,采用一种充气式园顶代替原来的固体结构,这种结构便于运输、装配而且成本低,所存在的唯一问题是入口和出口端的密封。 新模拟器大约有比周围更好一些的30°视场,在一定角度范围内安装的投影器使飞行员眼睛水平线以上的垂直视场增加到100°（在头部上方留有许可的视野情况下）。在方位方向,现在的视场是每边150°,这是用重新设计的龙门架支撑投影器来完成的。英国航宇公司按非成本效率进一步考虑增大视场,而与实际飞机的视觉相比,该系统仅失去少量视觉。 主要的改进是增强了计算能力,公司的一个浮点AP—12OB矩阵处理机加上32位VAXll/780计算机能够做许多简单的快速计算。英国航宇公司这种计算机系统使最大刷新速度从25赫增加到300赫,应用这种速度是为了空气动力计算和显示驱动,较低的刷新速度对于气动数据及划线计算也是足够的。 在每个球顶内,目标是一个模型的投影闭路电视图象,该模型是按照计算的飞机姿态运动的,有两个目标机模型,一个机头朝前安装,另一个机尾朝前安装,其距离变化
British Aerospace Company used the basic principle of the previous single-dome air combat simulation equipment and decided to make several improvements based on previous experience and the requirements for developing the training potential of the simulator. Instead of using the original solid structure with an inflatable garden, This structure facilitates transportation, assembly and low cost, with the only problems being the sealing of the inlet and outlet ports. The new simulator has about a 30 ° field of view that is better than the surroundings, and projectors installed over a range of angles increase the vertical field of view above the pilot’s eye level to 100 ° (with a permitted field of view above the head ). In azimuth, the current field of view is 150 ° on each side, which is done with the redesigned gantry supporting the projector. British Aerospace further considered non-cost-effective increases in the field of view, and compared to the actual aircraft vision, the system lost only a small amount of vision. The main improvement is the increased computational power. One of the company’s floating-point AP-12OB matrix processors plus a 32-bit VAX11 / 780 computer can do many simple quick calculations. This type of computer system at British Aerospace has increased the maximum refresh rate from 25 Hz to 300 Hz. This speed is used for aerodynamic and display drives, and lower refresh rates are sufficient for aerodynamic data and scribing calculations. In each dome, the target is a projected CCTV image of a model that is based on a calculated attitude of the aircraft with two target models, with one nose mounted forward and one tail facing forward , Its distance changes
