Reducing cost and increasing efficiency, starting from “small”
Recently, AVIC launched the project application and project approval work of “five primary schools” of cost engineering in 2020, collecting projects and suggestions on promoting scientific research and production technology improvement, cost saving and efficiency improvement, etc., so as to stimulate the enthusiasm of employees to participate in cost reduction and efficiency increase, and deepen the effective implementation of cost engineering.
Focus on Problems and improve quality
Recently, China Hangfa Dong’an line held an assembly product quality improvement project meeting to analyze the root causes of the low-level assembly quality problems diagnosed from the aspects of process management, quality control and production management, and formulate solutions to promote the quality improvement of assembly products.
Loop iterative re optimization
Recently, AVIC Power Institute of China organized and carried out the “redesign” activity of engine, comprehensively summarized the redesign work results from the aspects of engine development capacity and system construction, displayed and exchanged typical cases, promoted the implementation of “redesign” achievements, and helped improve engine design and R & D system capacity.
Increase production capacity and reduce inventory
Recently, the construction of China Southern test tube control center has made phased progress. Through the intelligent analysis of assembly process information, the maximum simultaneous assembly quantity is calculated, so that the warehouse rolling operation can reduce the inventory pressure and further improve the assembly efficiency.
AEOs construction speeds up again
Recently, China Aviation Development turbine Institute organized a work meeting of AEOs construction leading group office. Discuss and exchange the framework model, organizational structure, management regulations and 2020 top-level strategic deployment objectives of AEOs construction, and arrange the follow-up key work to accelerate the pace of AEOs construction.
Picture of the day
The national development and Reform Commission said on March 23 that the state will give subsidies to small and medium-sized and micro enterprises to recruit graduates, making it clear that state-owned enterprises should expand the recruitment scale of graduates for two consecutive years.
Recently, with the global outbreak of coronavirus, the major aviation and space activities in Europe in summer, such as van Burow air show and Royal International Air Show (RIAT), were cancelled.
Recently, Gulfstream Aerospace’s new g700 business aircraft is equipped with performance enhanced winglets made by DAHER. The winglet is made of composite metal hybrid components, which are bent upward at the wing tip of the aircraft for aerodynamic extension components, thus achieving structural and weight optimization and enhancing aesthetic feeling.
Learn once a day
The application of ceramic matrix composites (CMC) in aeroengines and hypersonic vehicles is expanding. Its high reliability and high precision machining is a great challenge to the traditional processing technology system of metal. As a solution, laser technology can improve the processing efficiency and end the repetitive cost of cutting tools, but the heat generated by laser will be transmitted to the material, which may produce microcracks and material degeneration; laser cutting at the focus of the beam will also lead to V-notch, which will affect the accurate control of the common error. Compared with the traditional laser, this technology will not make the material burn or thermal degradation, produce less burr, make the surface smoother, and can achieve straight edge cutting and higher precision.
Laser plays an increasingly important role in aviation manufacturing. The application of laser micro jet technology further illustrates this point. Laser micro jet can improve the processing efficiency and product quality of ceramic matrix composites and carbon fiber composites. With the continuous expansion of the application of aviation composite materials, similar innovative processes will continue to emerge in the future to subvert the existing traditional technology mainly developed for metal processing.
