Today, the Shenzhou 13 manned spacecraft was successfully launched at the Jiuquan Satellite Launch Center.
With the rapid development of the aerospace industry, staying in the "Chinese space station" has become the new normal, the 149 factory of the Eighth Academy of China Aerospace Science and Technology Group grasps the new situation and new requirements, opens up the "new production capacity, new technological process, new management mode", comprehensively improves the equipment supply guarantee capability, enhances the pattern of independent innovation, enhances the service and integration into the new development pattern, always grasps the pulse of the times, shoulders the mission and responsibility in the fight, and bravely climbs the new "peak" of manned engineering.
New production capacity: Promote the construction of "digital" final assembly plants
In the face of the situation of multi-model and new normal, Factory 149 has carried out special planning with the goal of "grasping the whole, controlling the process, improving efficiency and strengthening quality", taking the problem as the guide and focusing on front-line technological innovation, thereby changing the production mode and promoting the construction of the "digital" assembly plant.
In recent years, a series of digital developments applicable to Shenzhou spacecraft have gradually entered the main line of production. In the construction of the problem-oriented and digital special project of quality and efficiency, the team has established product-oriented design simulation capabilities around the digital process layout of the model, carried out the design of conduits and cable networks, branch design, and then to the on-site process design process, and gradually opened up the digital work mode.
"As the pipeline of aerospace products, in fact, they are like our blood vessels, they have their own unique 'dna'." Pi Gang, director of the third department of the 149 factory (ninth branch factory), looked at the intricate conduit and said, "The original manual bending production efficiency is relatively low, we are now through digital manufacturing, the constraint parameters and production needs to adapt, so that the digital technology of the product control to achieve the best, so as to achieve the catheter production once formed." ”
After the digital catheter production was officially applied to the assembly site, Ge Jiajun, the main post of the 149 plant pipeline, compared the product map from a seemingly similar catheter, and changed the original multiple revision of the pipeline and installation coordination into a comparison and installation, and the environmental control pneumatic pipeline was shortened from the original production time of nearly one week to two days, which greatly improved the production efficiency and quality of the assembly.
New management model: production and insurance work escorts "Shenzhou"
In order to adapt to the construction of China's space station engineering tasks, Factory 149 carried out the work of "product" and "personnel" in two dimensions, thus solving the working state of "people staring at people" and "people staring at products", and releasing more capacity to ensure the circular production of model tasks.
In the "product" dimension, Factory 149 has realized the transformation from single product delivery to "group production" of small batch product production delivery. In terms of first delivery time management, the team clarifies the relationship between production time and product effectiveness from raw material procurement, such as preparation of materials, conduit production, cable network preparation, product assembly delivery, etc., so as to ensure that the technical requirements and product quality are "double implemented". At the same time, in terms of product traceability management, the team refines the management measures for the entry and exit and storage of supporting products, refines the management mechanism of the periodicity and overlap rate of ground equipment and facilities and equipment, and establishes long-term closed-loop management of "peripheral" products, so that the "tracks" of products can be traced.
In the "personnel" dimension, the team is mainly based on professional skills, highlighting professionalism, improving comprehensiveness, and cultivating "one specialty, multiple abilities" compound talents, so as to maintain the stability of the team and adapt to the normalization of work in the new era.
For "post-95" Ling Xiaofeng, since he joined the company for more than a year, he has changed from a general assembly second post to a "little mage" of the Tianzhou and Shenzhou experimental tasks. In the "big belly" of the propulsion module, the pipes and cables are "crisscrossed" between the two. In order to make them "complement each other", he always refers to the cable file first and carefully determines the characteristics and specifications of each cable. He said that only by understanding the "ins and outs" of all products can we truly understand the principle, do a good job, eat the problem "thoroughly", and not let go of any "doubts". Because of this, the team has trained the comprehensive ability of "understanding the principle and proficient in equipment, being able to operate accurately in place, and being able to deal with calm responses", and always "do things right and do well the first time, and strictly handle every pass." As the most basic requirement, shoulder the burden of "thousands of gold" in the space industry.
Whether it is driven by the development of the times or the responsibility of the space mission. A new journey has begun, the 149 factory will have higher requirements, more stringent standards, they are unswervingly galloping on the new runway, with their own hard work and sweat to cultivate the stars, the dream of aerospace.
