Since 2001, Yantai Hongyuan oxygen Industry Co., Ltd. has accepted the development of Shenzhou series simulated return capsule, an important scientific and technological research project of the General Equipment Department of the Chinese people's Liberation Army. Through close cooperation with relevant domestic experts, overcoming many difficulties and organizing scientific and technological research, Yantai Hongyuan oxygen Industry Co., Ltd. successfully completed the task in a relatively short period of time, and produced a simulation return capsule with advanced technology and reliable quality.

       The simulated re-entry module has two types: Marine and land-based, which are mainly used for astronaut escape training; GPS satellite positioning search and rescue; salvage experiment and training in low sea conditions; and on-site disposal training of simulated re-entry module on the ship deck. After repeated tests and experiments, the technical parameters and performance of the equipment meet the requirements of the relevant departments of the state, and have good stability and advanced nature. The equipment has been recognized and praised by the relevant departments and users. Since 2001, Yantai Hongyuan oxygen Limited by Share Ltd has manufactured the simulated return capsule 4. Taiwan has made due contributions to the successful launch of Shenzhou series spaceships!
