Display System Solution

　　Off-axis virtual image display system. The principle is that the image of the back projection screen acts as an object in the system, and is placed off-axis in the focal plane of the Spherical Mirror, forming a orthostatic magnified infinite virtual image at the eye point. In front of the pilot to form a continuous, deep sense of the extravehicular scene, and produce the pilot in the air consistent with the visual effect.

　　The system consists of two parts: the display and the housing. The display part consists of spherical collimation mirror, back projection screen, Gantry, spherical reflector base, Projector Bay, back projection screen cover, spherical reflector cover, negative pressure control system, mask and other major components; The display part aims to form a dark space for an optical system to work and form a good imaging environment. At the same time, each component of the display part has strict requirements of strength and stiffness to meet the installation needs of optical components. Simple housing (including platform maintenance ladder) and other components

MATERIAL AND PROCESS DESCRIPTION:
　　The projection screen, the shading plate, the cockpit wall plate connection place uses the metal type riveting welding structure, the material uses the glass fiber reinforced plastic. With anti-corrosion, waterproof, fire-proof, moisture-proof insulation characteristics. And it has enough strength to ensure that it will not deform during normal use. The exterior of the cockpit will be customized to 1:1 size of the real cockpit, made of fiberglass, which will not only have a certain strength, but also reduce the weight of the ball screen display system. The base of the moving platform, the bracket of the projector and the Keel of the rear cabin are designed with high strength structure, so that the whole display system will not deform under the normal use of the simulation system. All metal surfaces shall be smooth and free of burrs; joints between different metals shall be provided with the necessary corrosion protection; all rivets shall be precisely positioned and aligned, and all rivets shall be fully filled with rivet holes. The whole adopts the unique streamline design. Additional Ladders, boarding ladders, guardrails. Ensure the overall effect of beautiful, strong, environmental protection, easy to clean.

Interior design:
Installation of internal cabin operating mechanism; installation of loudspeakers for the sound simulation system, cockpit lighting, ventilation, and low-light video monitoring system for the monitoring of the cockpit. The ball curtain will be equipped with ventilation channels for the cab’s heat dissipation and ventilation, to keep the cab’s air fresh. The ventilation system will be designed by the air conditioning supplier. Operating continuously for 12 hours, the average temperature in the cab does not exceed 23 ° C-28 ° C.
