The Jiaotong University helps to "ask the sky" to set sail and go to deep space!

At 14:22 on July 24, 2022, Beijing time, at the Wenchang Aerospace launcher in China, the Long March 5 Yao Three Laureate Rockets put the first experimental compartment of the China Space Station — Ask the Sky Experiment Curring, accurately send it into the scheduled track, the task is successful success.

Ask the Tianyan experimental cabin is the first experimental compartment of my country's space station. The experimental cabin is huge, powerful, complex in structure, and advanced indicators, condensing the wisdom and hard work of countless people. Among them, the National Key Laboratory of Shanghai Jiaotong University and Metal Base Composite Materials made important contributions to the development and supply of light -quality high -strength multi -functional metal base composite materials that help my country ’s space station“ asking Tianqi ”!

Super long wing exhibition, refresh the domestic solar wing

Maximum record

At 3:13 on July 25th, I asked the Tianhe Experimental Curring to successfully connect to the front port of the heaven and core compartment. The solar wing of the Tiangan experimental cabin was successfully expanded, providing the need for the power guarantee for the work of the Tianjin experimental cabin!

Asking the solar wing of the Tianjin experimental cabin is the main source of work and living electricity in the space station. In addition to the use of equipment in the space station, it is also necessary to store electrical energy. The materials of the exhibition agency that supports the solar wing work must have light quality, high -strength, high -mode volume, and high wear resistance, and under temperature changes, the materials and institutions must have size stability to ensure and support the solar wings in complex and harsh and harsh. Working normally under the conditions of multiple games!

With more scientific experimental tasks, the demand for material performance in the space station has also doubled. Compared with the Tianhe core cabin, asking the sun wings of the Tianhe experimental cabin to be longer, larger, higher -bearing requirements, and more stringent service conditions. With such a large pair of "soft wings" It is unprecedented to control the difficulty.

Asked the exhibition and support institutions of the solar wings of the Tiangtian Experimental Cels adopted ten specifications developed by Shanghai Jiaotong University and metal -based composite materials, hundreds of light -quality high -performance multifunctional aluminum -based composite materials and components It supports the maximum area developed by my country that can be exhibited flexible solar wings. The single -wing is 27 meters long and the area can reach 138 square meters. The sky and the core cabin sun wings are twice as many as the electric energy necessary for work and life every day. The energy generated is enough for ordinary families to use it for one month to effectively ensure the simultaneous operation of multiple experimental load projects in the space station and refresh the refresh my country's spacecraft uses the record of the sun wings on the orbit.

Light quality, "material" to help the sky dream of the sky

In order to develop a large -scale aerospace exhibition and supporting mechanism such as a huge -scale spacecraft such as the Sky Experimental Card, the supporting mechanism of the supporting institutions with a light and high -strength metal -based composite material, Shanghai Jiaotong University, metal -based composite materials, Professor Zhang Ye, Ouyang The team of Professor Professor Professor's team on the strict requirements of the comprehensive performance of materials for the comprehensive performance of materials in the space station solar wing exhibition agency, and in the existing application basic research, through the in -depth system, the system has been developed from the design optimization, composite processing, formation processing, and the actual service environment of the system. Basic research, further optimize research on the composite process and processing molding of materials and components, have the courage to innovate breakthroughs, overcome all kinds of unimaginable difficulties. The urgent demand light, high -strength multifunctional aluminum -based composite material, has been successfully applied to the solar wing exhibition agency of my country's space station "Tianhe Core Card" on April 29, 2021.

This is the team's great goal of the team's space station combination after the successful launch of the "Tianhe Core Card", which once again helped my country's space station combination.

The solar wing of the Tiantian experimental cabin is not only much larger than the sky and the core compartment, but its design requirements are also more stringent. The development of the sun wings will be carried out in seven steps in "two steps". During this period, there will be a "midfield rest", which takes 80 minutes throughout the journey. It is necessary to complete the hardcore technical actions that are "high -reliable and reliable can be exhibited", which are locking, tightening, re -expanding, and locking. At the same time, the collision shock load generated during the interchange of the composition of the experimental compartment and the space station combination. During the service of the later space station, the solar wing of the Tiangan experimental cabin must be turned to the sun for 24 hours through the dual degree of freedom to ensure the efficiency of the highest state power generation. Therefore, the solar wing of the Tiangtian experimental cabin proposes a more rigid, tough, wear -resistant, impact resistance, and harsh comprehensive performance requirements for its stretching mechanism. Zhang Ye and Ouyang Qi Insurance Research Team of the National Key Laboratory of Metal Base Composite Materials provided key materials and component guarantee for the skeleton of "free, rigid and soft" of the skeleton of the experimental compartment , Always ensure "electricity online".

Professor Zhang Ye and Professor Ouyang Qianshong have independently developed and developed in response to the difficulty of compound regulation, interface matching, and difficulty in deformity processing in restricting the use of non -continuous enhanced metal base composite materials in my country. Research and application of basic research, and continue to improve the performance of various materials, forming a batch, multi -variety development and production capacity of high -performance aluminum -based composite materials, and look forward to the national key laboratory of Shanghai Jiaotong University and metal -based composite materials to achieve China's aerospace The dream of a strong country has made greater contributions!
