3-in-1 Functional Clamshell Sky Dome (equipment required for observatories, planetariums, astronomical museums, and omnimax theaters integrated systems)

The three-in-one clamshell observatory, planetarium, and astronomy dome screen is one of the key equipment of the "Cosmos Exploration Hall," available in sizes from 3m to 12m (typically 7m to 9m). This large-scale astronomical educational equipment boasts multiple functions including an observatory, planetarium hall, dome cinema, and astronomy center. The clamshell dome screen system comes with an integrated skylight (no additional structure required), offering a dual-directional double-group astronomical dome when open, and a planetarium hall canopy when closed (with a perfectly rounded inner canopy) and can also expand the dome cinema screen function. The clamshell dome screen is designed based on Bernoulli's principle of fluid mechanics, ensuring the scientific safety and reliability of the system. The left and right dome screens are designed with an overlapping structure and differential control technology to ensure consistent and seamless seams.
