The sky light environment simulation system can manually simulate all the all-weather sky light environments encountered in flight on the ground, take the optical integration test of each type of cockpit as the starting point, take each model of head prototype as the maximum subject, and fully consider the scalability of subsequent models in order to adapt to the subsequent derivative or new aircraft cockpit. This system provides multi-functional and reproducible optical verification conditions for the optical integration design of the cockpit, visual efficacy design, verification test, human factor engineering research, etc. The prototype transshipment system in the optical environment simulation includes a platform car, prototype transshipment tooling, and dispatching management system. It can transfer each type of aircraft head prototype to the internal designated test point of the sky light environment simulation to conduct various cockpit-related experimental research.
