"Ask the sky" to explore the sky what to "ask" what "heaven"?Vice Chairman of the reporter connection to the International Aerospace Space Transport Committee

Zhejiang News Client reporter He Dongjian

At 14:22 pm today (24th), the Long March 5 Yao Three Lauret Rockets bearing the Experimental Class "One Flying to the Sky" from Wenchang Aerospace launches. After about 495 seconds, I asked the Tianjin Experimental Cels and the Rockets to be separated and entered the predetermined orbit, and the launch was successful.

It is understood that the Tianshi Experimental Curring is the first laboratory module of China Tiangong Space Station. The upcoming launch is the Tianzhou 5 freight ship, Shenzhou 15 manned spacecraft, etc. After the arrival of the Mengtian experimental cabin, you can form a space laboratory with Tianhe, Tian, ​​and Mengtian as the core. Basically, the goal of building Tiangong Space Station can be completed. You can carry out multi -disciplinary cross -space scientific research to reach the international advanced level.

Maybe many friends want to ask, what tasks do the questioning compartment of this launching test compartment do? Yang Yuguang, vice chairman of the International Aerospace Space Transport Committee of this side reporter, chose a few interesting pieces of them, and asked him to interpret the magic of this task.

Two major studies explore the mystery of the universe

Yang Yuguang told us that the scientific experiments that asked the Tiandi experimental cabin include two categories: scientific research and engineering research.

When it comes to space, everyone will emerge like the astronauts float in the space station, as if they are completely separated from the restrictions of gravity. In fact, astronauts are not zero -gravity but in a micro -gravity state in the space capsule.

"The scientific research in the space station mainly uses its unique micro -gravity environment and high radiation environment, and the environment that is not interfered with by the earth's atmosphere for scientific exploration." Yang Yuguang said. Qi Tian's experimental cabin is equipped with a gravity science experimental cabinet and biotechnology experimental cabinet, which can conduct research on biomagram mechanisms under different gravity.

For example, the liquid bridge capacity of the liquid bridge in my country No. 2 in China is of great significance to the basic research of the flow and dispersing mechanism of the space and the dispersion mechanism.

The universe is so vast. The earth is just a drop in the sea. Why should we explore time and labor?

When human beings are still obscure, they are curious and exploring the distant starry sky, observation of the starry sky and observation of the age of the starry sky, making astronomy one of the oldest subjects in human history.

"What is the practical significance of human spending effort to find the cosmic celestial bodies such as pulse stars and supernovas? Scientific research is the need for humans to explore unknown needs, and it is not necessary to have a designated goal." Yang Yuguang said.

In addition, in the test compartment, engineering research is also essential. According to Yang Yuguang, some of the engineering research in the universe serves the aerospace itself, such as the iteration upgrade of the spacecraft, the performance of a certain precision component in space, and some provide ideas for the ground.

"We intend to use space micro -gravity, high vacuum, super clean, strong radiation and rich solar energy to prepare for the earth's high -quality products that are difficult to make or costly costly, such as high -purity large crystal silicon materials for electronic industry.铟 材 材 and other materials; these use of special environmental conditions for space to carry out theoretical research and practice of materials preparation will be the prototype of the future space manufacturing and space industry. Once the cost of round -trip costs is solved, space manufacturing will directly benefit all human beings ."He says.

Short truss design provides sufficient energy

Asked about the total length of the experimental compartment of 17.9 meters, which is equivalent to the six -story building, which is the longest -directional single spacecraft in the world. In terms of design, the end is designed with a short truss, using the questioning compartment of the sky and the subsequent Dreaming experimental compartment confront layout to form a horizontal 40 -meter span.

"This is where our space station is clever." Yang Yuguang said that similar spacecraft usually arranged solar exhaust (also known as the solar wings) in the middle of the cabin, but on the asks of the day and Dream Tianshi experimental cabin, solar energy, solar energy The winding rolls are located at the tail of the cabin. Asking the cabin and Mengtian's cabin played a similar role as the international space station, so that the two pairs of solar windsurdies will not be blocked.

Earlier in the early years, the number of solar energy windsuries on the third -generation space station was not small, but due to improper design, the windsurfing on the cabin was blocked each other, so the power generation efficiency was not high.

He said happily: "More importantly, it uses two sets of independent and vertical shafts, which can adjust the optimal direction at any time to collect solar energy."

Ask the solar tanks of the Tiangtian experimental cabin with a flexible three -tiers arsenide battery with high photoelectric conversion efficiency, which has a conversion efficiency of more than 30%. One -day power generation can be used for ordinary Sankou home for one and a half months.

In addition to providing energy to scientific research, solar windsurfing also undertakes its own operation and the entire space station power supply. Therefore, the dilemma of picking up the search in the laboratory in space is gone.
