"Twin" different wonderful

Without any drawing models, more than 3 million components were simulated and tested in virtual space. The final rework volume was reduced by 50%, and the R & D cycle was shortened by 40%. This is the achievement created by the Boeing 777 passenger plane using digital twin technology.

A model of the same thing in the virtual world of the computer is exactly the same as the real thing. The two are like a pair of twins, which is "digital twin". Digital twins that start in the field of aviation are moving towards more fields. Rockets are also in -depth research and apply digital twin technology in different fields.

Make the future rocket smarter

What kind of sparks will digital twin technology be wiped out if combined with the rocket?

The Rocket Institute Research and Development Department is conducting relevant thinking and research.

According to Wang Haoliang, the designer of the Ministry of Studies and Development, based on digital twin technology, designers can realize parallel mirror images of rocket production plants and even development processes in the future. According to the needs of the task, they can independently seek excellent engine selection and dynamic optimization of rocket architecture design. Equipment and manufacturing processes, virtual production, virtual trials, and parallel guide rocket production and development.

At the same time, the digital twin of the carrier rocket can record the life cycle of each batch of the carrier rocket and each component in real time. Based on the performance of each part in the actual flight process of each part in the carrier rocket digital twin simulation flight test and the actual flight process of twin acquisition, intelligent global excellence, optimizing the design of the rocket structure and control system to provide support for the improvement of the product.

Not only the Rockets develop and test can be used in digital twin technology. In the future, this technology can also be applied to the production and assembly of the Rockets. Parallel mirror rockets from workshop parts to large components and the assembly of the entire arrow. The mirror and analyzes the abnormalities that may affect the rocket operation. Dynamic reminders of some unspoken components, unconnected installations, etc., fundamentally reduced the failure of faults.

Nature reserve management is more direct

The area of ​​the forest land of the protected area, the number of wild protection animals and plants, population conditions, mountains, rivers, and engineering construction situations are clear at a glance in the "certain natural environment and resource comprehensive visual management system".

This system is created by the Beijing Aerospace Automatic Control Research Institute in the Rocket Institute, which is based on the comprehensive management of natural environment and resources. The three -dimensional visual surveillance technology of "what you see is obtained" can realize "all -weather, full elements, and all -round". Through it, the protection site can timely understand the growth of vegetation in various regions in the park, and it can also detect personnel and animals in the park and animals in the park. Movement tracking.

At the same time, this system is deductible. According to the collected data information, the protection of weak protection during natural disasters is deduced, manual intervention is dispatched in advance to reduce the incidence of accidents. This system is of great significance to improving the security of the entire nature reserve.

The gas station is safer

Gas leakage can easily cause explosion accidents, so the safety of gas field stations is very important. Beijing Aerospace Wanyuan Technology Co., Ltd.'s Beijing Aerospace Top Tortex High Technology Co., Ltd. applied digital twin technology in the field of energy and developed the "Digital Twin Smart Field Station" to escort the safety of gas delivery.

Digital twin smart field stations are supported by key technologies such as digital twin model construction and AI+algorithms. The full -scale stations and full -time information of the energy field station line and more accurate control can be achieved.

Compared with the traditional energy field management mode, the digital twin smart field station has 4 advantages: uncertainty or unsafe factors to reduce human reasons, improve the operating efficiency and reliability of the stations; reduce or avoid people's patrol patches Inspection, thereby reducing the duration of personnel in the dangerous area; reducing the risk of operation and operation of the smart equipment on the stations, increasing the level of prediction of operation and maintenance; saving management costs, human resources, and operation and maintenance costs.

At present, the "Digital Twin Smart Field Station" has been promoted and applied at a gas field station. In addition, it can be used in the fields of heat, water, and enterprise production.

China has positioned digital twin technology as one of the seven new generation of digital technologies. It represents a major direction of future scientific and technological development. Rocket Academy follows the trend of scientific and technological development and use digital twins to create different wonderful excitement in different fields.
