On August 31, in the high-end equipment manufacturing workshop of Baoti Group, the "Warm Congratulations to the Completion and Delivery Ceremony of the Titanium Alloy Manned Ball for Ten Thousand Meters Deep Submersible" was held, which marked the domestic 10,000m deep sea submersible titanium alloy manned ball. The cabin was successfully developed.

After three and six months, the 702nd Research Institute of China Shipbuilding Industry Corporation was responsible for the design, and Baoti Group undertook the manufacturing and processing of the national key research and development plan "Development of titanium alloy manned cabin for deep-sea manned submersibles" project, research and manufacture Make milestone progress.

On the morning of August 29th, Ye Cong, a national pioneer of reform, deputy director of the 702nd Research Institute of China Shipbuilding Industry Corporation, and chief designer of 10,000-meter manned submersibles, went to Baoti Group to discuss the "Titanium Alloy Carrier for All-Sea Deep Manned Submersibles" "Human cabin development" project team leader Jia Shuanxiao, general manager of Baoti Co., Ltd., Wang Dingchun, deputy general manager, and project team members went to the deep-sea submersible titanium alloy manned spherical cabin manufacturing and processing site to witness the assembly process of the manned spherical cabin. In a series of inspections, all components meet the requirements of the drawings, successfully assembled, and the manned ball cabin is allowed to leave the factory after completion.

Chief planner Ye Cong fully affirmed the work undertaken by Baoti Group in the development of 10,000-meter-scale manned titanium alloy spherical cabin, and congratulated the project for multiple technological breakthroughs and development results, and represented the overall project The team would like to express its heartfelt thanks to the leaders at all levels of Baoti and all the participants for their hard work! He said that the successful development of the manned ball cabin has greatly improved my country's manned deep-diving equipment manufacturing technology and brought my country's manned deep-diving career to a new level.

The 10,000-meter manned submersible is a manned submersible that is independently designed, developed and manufactured by my country after the 4,500-meter manned submersible of the "Deep Sea Warrior". Its operating range can cover all sea areas in the world. The manned ball cabin is the core component of the manned submersible, and its manufacturing quality is the basic guarantee for the life safety of the submariner. As the diving depth of the submersible and the size of the ball cabin increase, the difficulty of development has increased exponentially. The manned spherical capsule developed by this plan is the deep-sea manned capsule with the largest space and the largest number of people in the world. Its design and manufacturing requires the integration of top technologies in multiple fields and multiple disciplines, making it difficult to successfully develop.

During the development of the 10,000-meter manned submersible, Baoti Group undertook the research and development of all titanium components except the main frame, including the manned spherical shell. The project team has overcome many difficulties such as short development cycle and heavy tasks. It took three years to successfully break through a number of key technologies and fill in many technical gaps in the international titanium and titanium alloy fields. The research and development technology and results have been unanimously recognized and praised by the Ministry of Science and Technology, the overall project unit and the expert group.

The titanium alloy manned spherical cabin of the 10,000-meter manned submersible is another manned spherical cabin developed by Baoti Group after the “Deep-Sea Warrior” manned spherical cabin. Its successful development makes the deep-sea pressure equipment manufacturing technology of Baotai Group reach It has achieved a new height and accumulated rich practical experience for the future development of similarly difficult titanium and titanium alloy equipment. At the same time, it will lay the most solid foundation for the smooth and safe dive of China's 10,000-meter-class manned submersible, which will enable China's deep sea The research and development technology in the field of detection and equipment has achieved a historic leap from "parallel running" to international "leading".
